Never allow children or people unfamiliar with these instructions to use or service the mower. Local regulations may restrict the age of the operator.
Never mow while people, especially children, or pets are nearby.
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property.
Do not carry passengers.
All drivers and mechanics should seek and obtain professional and practical instruction. The owner is responsible for training the users. Such instruction should emphasize the the need for care and concentration when working with ride-on machines.
The owner/user can prevent and is responsible for accidents or injuries occurring to people or damage to property.

Preparation

While mowing, always wear substantial, slip-resistant footwear, long trousers, safety glasses, and ear protection.
Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine.
Replace faulty silencers/mufflers.
Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by the manufacturer.
Check that the operator's presence controls, safety switches and shields are attached and functioning properly. Do not operate the machine unless they are functioning properly.

Safe Handling of Fuels

To avoid personal injury or property damage, use extreme care in handling fuel. Diesel fuel is extremely flammable and the vapors are explosive.
Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
Use only an approved fuel container.
Never remove the fuel cap or add fuel with the engine running.
Allow engine to cool before refueling.
Never refuel the machine indoors.
Never store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.
Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle before filling.
Remove equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container rather than from a fuel-dispenser nozzle.
Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock open device.
If fuel is spilled on clothing, change clothing immediately.
Never overfill fuel tank. Replace the fuel cap and tighten it securely.

Operation

Do not operate the engine in a confined space, where dangerous carbon monoxide and exhaust gases can collect.
Mow only in daylight or in good artificial light.
Before attempting to start the engine, disengage all blade attachment clutches, shift into neutral, and engage the parking brake.
Use counterweight(s) or wheel weights as recommended in the Operator's Manual.
Stay alert for holes in the terrain and other hidden hazards.
Watch out for traffic when crossing or near roadways.
Stop the blades rotating before crossing surfaces other than grass.
When using any attachments, never direct discharge of material toward bystanders nor allow anyone near the machine while in operation.
Never operate the machine with damaged guards, shields, or without safety protective devices in place. Make sure that all interlocks are attached, adjusted properly, and functioning properly.
Do not change the engine governor settings or overspeed the engine. Operating the engine at excessive speed may increase the hazard of personal injury.
Before leaving the operator's position, do the following:
- Stop on level ground.
- Disengage the power take-off and lower the attachments.
- Change into neutral and set the parking brake.
- Stop the engine and remove the key.
Disengage drive to attachments when transporting or not in use.

- Before removing the grass catcher/catchers
- Before making height adjustment unless adjustment can be made from the operator's position
- Before clearing blockages
- Before checking, cleaning or working on the mower
- After striking a foreign object or if an abnormal vibration occurs. Inspect the mower for damage and make repairs before restarting and operating the equipment
Reduce the engine speed setting during engine run-out and, if the engine is provided with a shutoff valve, turn the fuel off at the conclusion of mowing.
Keep hands and feet away from the cutting units.
Look behind and down before backing up to be sure of a clear path.
Slow down and use caution when making turns and crossing roads and sidewalks. Stop cylinders/reels if not mowing.
Do not operate the mower if tired, ill, or under the influence of alcohol or drugs.
Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine; seek shelter.
Use care when loading or unloading the machine into a trailer or truck.
Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

Slope Safety

Slow down the machine and use extra care on hillsides. Travel in the recommended direction on hillsides. Turf conditions can affect the stability of the machine.
Avoid starting, stopping, or turning the machine on a slope. If the tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.
Do not turn the machine sharply. Use care when reversing the machine.
When operating the machine on a slope, always keep all cutting units lowered.
Avoid turning the machine on slopes. If you must turn, turn slowly and gradually downhill, if possible.
Use extra care while operating the machine with attachments; they can affect the stability of the machine. Follow the recommendations for using the machine on a slope in this Operator’s Manual.

Maintenance and Storage

Keep all nuts, bolts and screws tight to be sure that the equipment is in safe working condition.
Never store the equipment with fuel in the tank inside a building, where fumes may reach an open flame or spark.
Allow the engine to cool before storing in any enclosure.
To reduce the fire hazard, keep the engine, silencer/muffler, battery compartment and fuel storage area free of grass, leaves, or excessive grease.
Check the grass catcher frequently for wear or deterioration.
Keep all parts in good working condition and all hardware and hydraulic fittings tightened. Replace all worn or damaged parts and decals.
If the fuel tank has to be drained, do this outdoors.
Be careful during adjustment of the machine to prevent entrapment of the fingers between moving blades and fixed parts of the machine.
On multi-cylinder/multi-reel machines, take care as rotating one cylinder/reel can cause other cylinders/reels to rotate.
Disengage drives, lower the cutting units, set parking brake, stop engine, and remove key from ignition. Wait for all movement to stop before adjusting, cleaning, or repairing the machine.
Clean grass and debris from cutting units, drives, silencers/mufflers, and engine to help prevent fires. Clean up oil or fuel spills.
Use jack stands to support components when required.
Carefully release pressure from components with stored energy.
Disconnect battery before making any repairs. Disconnect the negative terminal first and the positive last. Connect positive first and negative last.
Use care when checking the cylinders/reels. Wear gloves and use caution when servicing them.
Keep hands and feet away from moving parts. If possible, do not make adjustments with the engine running.
Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools.

Hauling

Checking the Engine-Oil Level

Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level.

Filling the Fuel Tank

Danger

In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

Fill the fuel tanks outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.
Never fill the fuel tanks inside an enclosed trailer.
Never smoke when handling fuel and stay away from an open flame or where fuel fumes may be ignited by a spark.
Store fuel in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of fuel.
Do not operate without entire exhaust system in place and in proper working condition.

Danger

In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property.

Always place fuel containers on the ground away from your vehicle before filling.
Do not fill fuel containers inside a vehicle or on a truck or trailer bed, because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.
When practical, remove equipment from the truck or trailer and refuel the equipment with its wheels on the ground.
If this is not possible, then refuel such equipment on a truck or trailer from a portable container rather than from a fuel-dispenser nozzle.
If you must use a fuel-dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Warning

Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

Avoid prolonged breathing of vapors.
Keep your face away from the nozzle and fuel tank opening.
Keep fuel away from your eyes and skin.

Fuel Specification

Important: Use only ultra-low sulphur diesel fuel. Fuel with higher rates of sulfur degrades the diesel oxidation catalyst (DOC), which causes operational problems and shortens the service life of engine components.Failure to observe the following cautions may damage the engine.

Never use kerosene or gasoline instead of diesel fuel.
Never mix kerosene or used engine oil with the diesel fuel.
Never keep fuel in containers with zinc plating on the inside.
Do not use fuel additives.

Petroleum Diesel

Cetane rating: 45 or higher

Sulfur content: Ultra-low sulfur (<15 ppm)

Fuel Table

JIS K2204 Grade No. 2	Japan
KSM-2610	Korea

Use only clean, fresh diesel fuel or biodiesel fuels.
Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

Use summer-grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter-grade fuel (No. 1-D or No. 1-D/2-D blend) below that temperature.

Note: Use of winter-grade fuel at lower temperatures provides lower flash point and cold flow characteristics which eases starting and reduces fuel filter plugging.Using summer-grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter-grade fuel.

Biodiesel

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petroleum diesel).

Sulfur content: Ultra-low sulfur (<15 ppm)

Biodiesel fuel specification: ASTM D6751 or EN14214

Blended fuel specification: ASTM D975, EN590, or JIS K2204

Important: The petroleum diesel portion must be ultra-low sulfur.

Observe the following precautions:

Biodiesel blends may damage painted surfaces.
Use B5 (biodiesel content of 5%) or lesser blends in cold weather.
Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time.
Fuel filter plugging may be expected for a time after converting to biodiesel blends.
Contact your Authorized Toro Distributor if you wish for more information on biodiesel.

Fill the tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.
Install the fuel-tank cap tightly after filling the tank.

Note: If possible, fill the fuel tank after each use. This minimizes possible buildup of condensation inside the fuel tank.

Checking the Cooling System

Maintenance Service Interval	Maintenance Procedure
Before each use or daily	Check the cooling system.

Clean debris off the screen, oil cooler, and front of the radiator daily and more often if conditions are extremely dusty and dirty. Refer to Removing Debris from the Cooling System.

The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol antifreeze. Check the level of coolant in the expansion tank at the beginning of each day before starting the engine. The capacity of the cooling system is 6.6 L (7.0 US qt).

Caution

If the engine has been running, the pressurized, hot coolant can escape and cause burns.

Do not open the radiator cap when the engine is running.
Use a rag when opening the radiator cap, and open the cap slowly to allow steam to escape.

Check the level of coolant in the expansion tank (Figure 29).

The coolant level should be between the marks on the side of the tank.
Figure 29

If the coolant level is low, remove the expansion-tank cap and replenish the system. Do not overfill.
Install the expansion-tank cap.

Checking the Hydraulic Fluid

Maintenance Service Interval	Maintenance Procedure
Before each use or daily	Check the hydraulic-fluid level.

The machines reservoir is filled at the factory with approximately 30 L (8 US gallons) of high-quality hydraulic fluid. Check the level of the hydraulic fluid before the engine is first started and daily thereafter. The recommended replacement fluid is as follows:

Toro Premium All Season Hydraulic Fluid (Available in 19 L (5 US gallon) pails or 208 L (55 US gallon) drums. See the Parts Catalog or your Toro Distributor for part numbers.)

Alternate fluids: If the Toro fluid is not available, other fluids may be used provided they meet all the following material properties and industry specifications. We do not recommend the use of synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product.

Note: Toro does not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who stand behind their recommendation.

High Viscosity Index/Low Pour Point Anti-wear Hydraulic Fluid, ISO VG 46
	Material Properties:
		Viscosity, ASTM D445	cSt @ 40°C 44 to 50cSt @ 100°C 7.9 to 8.5
		Viscosity Index ASTM D2270	140 to 160
		Pour Point, ASTM D97	-36.6°C (-34°F) to 9.4°C (-49°F)
	Industry Specifications:
		Vickers I-286-S (Quality Level), Vickers M-2950-S (Quality Level), Denison HF-0

Important: The ISO VG 46 Multigrade fluid has been found to offer optimal performance in a wide-range of temperature conditions. For operation in consistently high ambient temperatures, 18°C (65°F) to 49°C (120°F), ISO VG 68 hydraulic fluid may offer improved performance.

Premium Biodegradable Hydraulic Fluid-Mobil EAL EnviroSyn 46H

Important: Mobil EAL EnviroSyn 46H is the only synthetic biodegradable fluid approved by Toro. This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions. This fluid is compatible with conventional mineral oils, but for maximum biodegradability and performance the hydraulic system should be thoroughly flushed of conventional fluid. The oil is available in 19 L (5 US gallon) containers or 208 L (55 US gallon) drums from your Mobil Distributor.

Important: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 20 ml (2/3 oz) bottles. 1 bottle is sufficient for 15 to 22 L (4 to 6 gallons) of hydraulic oil. Order Part Number 44-2500 from your Toro Distributor. This red dye is not recommended for use with biodegradable fluids. Use food coloring.

Position the machine on a level surface, lower the cutting units, and stop the engine.
Clean the area around filler neck and cap of the hydraulic tank (Figure 30). Remove the cap from the filler neck.
Figure 30
1. Hydraulic-tank cap
Remove the dipstick from the filler neck and wipe it with a clean rag.
Insert the dipstick into the filler neck; then remove it and check the level of the fluid.

Note: The fluid level should be within 6.3 mm (1/4 inch) of the mark on the dipstick.

Important: Do not overfill.
If the level is low, add appropriate fluid to raise the level to the FULL mark.
Install the dipstick and cap onto the filler neck.

Checking the Reel-to-Bedknife Contact

Maintenance Service Interval	Maintenance Procedure
Before each use or daily	Check the reel-to-bedknife contact.

Each day before operating, check reel-to-bedknife contact, regardless if the quality of cut had previously been acceptable. There must be light contact across the full length of the reel and the bedknife (refer to Adjusting the Reel to Bedknife in the Operator's Manual for the cutting units).

Check the Torque of the Wheel Nuts

Maintenance Service Interval	Maintenance Procedure
After the first hour	Torque the wheel lug nuts to 94 to 122 N-m (70 to 90 ft-lb).
After the first 10 hours	Torque the wheel lug nuts to 94 to 122 N-m (70 to 90 ft-lb).
Every 250 hours	Torque the wheel lug nuts to 94 to 122 N-m (70 to 90 ft-lb).

Torque the wheel nuts to 94 to 122 N-m (70 to 90 ft-lb).

Warning

Failure to maintain proper torque of the wheel nuts could result in personal injury.

Burnishing the Brakes

To ensure optimum performance of the parking-brake system, burnish (break in) the brakes before use. Set the forward traction speed to 6.4 km/h (4 mph) to match the reverse traction speed (all 8 spacers moved to the top of the mow-speed control). With the engine at high idle, proceed forward with the mow-speed-control stop engaged and ride the brake for 15 seconds. Proceed backward at full reverse speed and ride the brake for 15 seconds. Repeat this 5 times, waiting 1 minute between each forward and reverse cycle to avoid overheating the brakes; refer to Adjusting the Parking Brakes.

Starting and Stopping the Engine

Important: The fuel system automatically bleeds itself when any of the following situations occur:

Initial start-up of a new machine.
The engine has ceased running due to lack of fuel.
Maintenance has been performed upon the fuel system components.

Starting the Engine

Sit on the seat, keep your foot off the traction pedal so that it is in NEUTRAL, engage the parking brake, set the engine-speed switch to the MIDDLE position, and ensure that the Enable/Disable switch is in the DISABLE position.
Remove your foot from the traction pedal and make sure that the pedal is in the NEUTRAL position.
Turn the ignition key to the RUN position.
When the glow indicator dims, turn the ignition key to the START position. Release the key immediately when the engine starts and allow it to return to the RUN position. Allow the engine to warm up (without load), then move the throttle control to the desired position.

Stopping the Engine

Move all controls to NEUTRAL, set the parking brake, move the engine-speed switch to the low idle position and allow the engine to reach low idle speed.
Turn the key to the OFF position and remove it from the switch.

Cutting Grass with the Machine

Note: Cutting grass at a rate that loads the engine promotes DPF regeneration.

Move the machine to the job site and align the machine outside the cutting area for the first cutting pass.
Ensure that the PTO switch is set to the DISABLE position.
Move the lever for the mow-speed limiter forward.
Press the throttle-speed switch to set the engine speed to HIGH IDLE.
Use the joystick to lower the cutting units to the ground.
Press the PTO switch to prepare cutting units for operation.
Use the joystick to raise the cutting units off the ground.
Begin moving the machine toward the cutting area and lower the cutting units.

Note: Cutting grass at a rate that loads the engine promotes DPF regeneration.
When you complete the mowing pass, use the joystick to lift the cutting units.
Perform a tear-shaped turn to quickly line up for your next pass.

Diesel Particulate Filter Regeneration

The diesel particulate filter (DPF) is part of the exhaust system. The diesel-oxidation catalyst of the DPF reduces harmful gasses and the soot filter removes soot from the engine exhaust.

The DPF regeneration process uses heat from the engine exhaust to incinerate the soot accumulated on the soot filter, converting the soot to ash, and clears the channels of the soot filter so that filtered engine exhaust flows out the DPF.

The engine computer monitors the accumulation of soot by measuring the back pressure in the DPF. If the back pressure is too high, soot is not incinerating in the soot filter through normal engine operation. To keep the DPF clear of soot, remember the following:

Passive regeneration occurs continuously while the engine is running—run the engine at full engine speed when possible to promote DPF regeneration.
If the back pressure is too high, the engine computer signals you through the InfoCenter when additional processes (assist and reset regeneration) are running.
Allow the assist and reset regeneration process to complete before shutting off the engine.

Operate and maintain your machine with the function of the DPF in mind. Engine load at high idle engine speed generally produce adequate exhaust temperature for DPF regeneration.

Important: Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the soot filter.

Caution

The exhaust temperature is hot (approximately 600°C (1112°F) during DPF parked regeneration or recovery regeneration. Hot exhaust gas can harm you or other people.

Never operate the engine in an enclosed area.
Make sure that there are no flammable materials around the exhaust system.
Never touch a hot exhaust system component.
Never stand near or around the exhaust pipe of the machine.

DPF Soot Accumulation

Over time, the DPF accumulates soot in the soot filter. The computer for the engine monitors the soot level in the DPF.
When enough soot accumulates, the computer informs you that it is time to regenerate the diesel particulate filter.
DPF regeneration is a process that heats the DPF to convert the soot to ash.
In addition to the warning messages, the computer reduces the power produced by the engine at different soot-accumulation levels.

Engine Warning Messages—Soot Accumulation

Indication Level	Fault Code	Engine Power Rating	Recommended Action
Level 1: Engine Warning	Figure 31 Check EngineSPN 3719, FMI 16	The computer de-rates the engine power to 85%	Perform a parked regeneration as soon as possible; refer to Parked Regeneration.
Level 2: Engine Warning	Figure 32 Check EngineSPN 3719, FMI 0	The computer de-rates the engine power to 50%	Perform a recovery regeneration as soon as possible; refer to Recovery Regeneration.

DPF Ash Accumulation

The lighter ash is discharged through the exhaust system; the heavier ash collects in the soot filter.
Ash is a residue of the regeneration process. Over time, the diesel particulate filter accumulates ash that does not discharge with the engine exhaust.
The computer for the engine calculates the amount of ash accumulated in the DPF.
When enough ash accumulates, the engine computer sends information to the InfoCenter in the form of a system advisory or an engine fault to indicate the accumulation of ash in the DPF.
The advisory and faults are indications that it is time to service the DPF.
In addition to the warnings, the computer reduces the power produced by the engine at different ash-accumulation levels.

InfoCenter Advisory and Engine Warning Messages—Ash Accumulation

Indication Level	Advisory or Fault Code	Engine Speed Reduction	Engine Power Rating	Recommended Action
Level 1: System Advisory	Figure 33 Advisory #179	None	100%	Notify your service department that advisory #179 displays in the InfoCenter.

Rear—rectangular axle tube on the rear axle.

Transporting the Machine

Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

Warning

Driving on the street or roadway without turn signals, lights, reflective markings, or a slow-moving vehicle emblem is dangerous and can lead to accidents causing personal injury.

Do not drive the machine on a public street or roadway.

If you are using a trailer, connect it to the towing vehicle and connect the safety chains.
If applicable, connect the trailer brakes.
Load the machine onto the trailer or truck.
Stop the engine, remove the key, set the brake, and close the fuel valve.
Use the metal tie-downs on the machine to securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes (Figure 57 and Figure 58).

Loading the Machine

Use extreme caution when loading the machine onto a trailer or a truck. Use a full-width ramp that is wide enough to extend beyond the front tires of the machine instead of individual ramps for each tire (Figure 59). If it is not possible to use a full-width ramp, use enough individual ramps to simulate a full-width continuous ramp.

The ramp should be long enough so that the angles do not exceed 15 (Figure 59). A steeper angle may cause mower components to get caught as the unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip backward. If loading the machine on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

Important: Do not attempt to turn the machine while on the ramp; you may lose control and drive off the side.

Warning

Loading a machine onto a trailer or truck increases the possibility of tipping over and could cause serious injury or death.

Use extreme caution when operating a machine on a ramp.
Use the ROPS (in the up position) while using the seat belt when loading the machine. Ensure that the ROPS clears the top of an enclosed trailer.
Use only a single, full-width ramp.
If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the machine.
Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.
Avoid sudden acceleration or deceleration while driving the machine up or down a ramp.

Repeat the procedure for all cutting units you want to backlap.
When finished, return the backlap levers to the MOW position, lower the seat, and wash all lapping compound off the cutting units.

Note: Adjust the cutting-unit reel to bedknife as needed. Adjust the cutting-unit reel speed to the desired mowing setting.

Important: If the backlap switch is not returned to the OFF position after backlapping, the cutting units do not raise or function properly.

Note: For a better cutting edge, run a file across the front face of the bedknife after lapping. This removes any burrs or rough edges that may have built up on the cutting edge.

Storage

Preparing the Traction Unit

Thoroughly clean the traction unit, cutting units, and engine.
Check the tire pressure. Inflate all traction unit tires to 83 to 103 kPa (12 to 15 psi).
Check all fasteners for looseness and tighten them as necessary.
Grease all grease fittings and pivot points. Wipe up any excess lubricant.
Lightly sand and use touch-up paint on painted areas that are scratched, chipped, or rusted. Repair any dents in the metal body.
Service the battery and cables as follows:
1. Remove the battery terminals from the battery posts.
2. Clean the battery, terminals, and posts with a wire brush and baking soda solution.
3. Coat the cable terminals and battery posts with Grafo 112X skin-over grease (Toro Part Number 505-47) or petroleum jelly to prevent corrosion.
4. Slowly recharge the battery every 60 days for 24 hours to prevent lead sulfation of the battery.

Preparing the Engine

Drain the engine oil from the oil pan and replace the drain plug.
Remove and discard the oil filter. Install a new oil filter.
Refill the oil pan with designated quantity of motor oil.
Start the engine and run it at idle speed for approximately 2 minutes.
Stop the engine.
Flush the fuel tank with fresh, clean diesel fuel.
Check antifreeze protection and add a 50/50 solution of water and antifreeze as needed for expected minimum temperature in your area.
Secure all fuel-system fittings.
Thoroughly clean and service the air-cleaner assembly.
Seal the air-cleaner inlet and the exhaust outlet with weatherproof tape.
Check the antifreeze protection and add as needed for expected minimum temperature in your area.

		The engine is cold—wait.
		The engine is warm—wait.
		The engine hot—regeneration in progress (percent complete).
