Slope Operation

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. operating the machine on any slope requires extra caution. Before using the machine on a slope, you must:
- Review and understand the slope instructions in the manual and on the machine.
- Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Always use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.
Raising the hopper on a slope affects the stability of the machine. Keep the hopper in the lowered position when on slopes.
When operating on a slope, fold the platform up and walk behind the machine until it is on flat ground.
Operate up and down slopes with the heavy end of the machine uphill. Weight distribution changes with a full hopper. A full hopper makes the front of the machine the heavy end, so when traveling up or down slopes with a full hopper, walk-behind the machine with the full hopper uphill.
Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water or other hazards. The machine could suddenly roll over if a wheel or track goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard.
Avoid starting, stopping, or turning the machine on a slope. Avoid making sudden changes in speed or direction; turn slowly and gradually.
Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.
Do not operate the machine under any conditions where traction, steering, or stability is in question. Be aware that operating the machine on wet grass, across slopes or downhill may cause the machine to lose traction. Loss of traction to the wheels or tracks may result in sliding and a loss of braking and steering. The machine can slide even if the wheels or tracks are stopped.
Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.
If you lose control of the machine, step off and away from the direction of travel of the machine.

Maintenance and Storage

Let the engine cool before storing and do not store the machine near an open flame.
Engage the parking brake, shut off the engine, remove the key, and wait for all movement to stop before adjusting, cleaning, or repairing the machine.
Clean debris from drives, mufflers, and the engine to help prevent fires. Clean up oil or fuel spills.
Do not store fuel near flames or drain indoors.
Park the machine on level ground. Never allow untrained personnel to service the machine.
Use jack stands to support components when required.
Carefully release pressure from components with stored energy.
Disconnect the battery, negative terminal first and positive terminal last, before making any repairs. Connect the battery positive terminal first and negative terminal last.
Keep your 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 the charger before connecting or disconnecting it from the battery. Wear protective clothing and use insulated tools.
Keep all parts in good working condition and all hardware tightened. Replace all worn or damaged decals.
Use the cylinder lock to secure the hopper in the raised position.
Keep nuts and bolts tight. Keep equipment in good condition.
Never tamper with safety devices.
Use only genuine Toro replacement parts to ensure that original standards are maintained.
Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes, and clothing. Protect your face, eyes, and clothing when working with a battery.
Battery gases can explode. Keep cigarettes, sparks, and flames away from the battery.
Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks; never use your hands. Hydraulic fluid escaping under pressure can penetrate skin and cause injury requiring surgery within a few hours by a qualified surgeon; otherwise, gangrene may result.

Adding Fuel

For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
ETHANOL: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.
Do not use gasoline containing methanol.
Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.
Do not add oil to gasoline.

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 tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.
Never fill the fuel tank inside an enclosed trailer.
Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows fuel to expand.
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, which 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 fuel-powered 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 nozzle and fuel tank or conditioner opening.
Keep fuel away from eyes and skin.

Using Stabilizer/Conditioner

Use fuel stabilizer/conditioner in the machine to keep the fuel fresh longer when used as directed by the fuel-stabilizer manufacturer.

Important: Do not use fuel additives containing methanol or ethanol.

Add the amount of fuel stabilizer/conditioner to fresh fuel as directed by the fuel-stabilizer manufacturer.
