-
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 in fuel containers over the winter unless you use a fuel stabilizer.
-
Do not add oil to gasoline.
Important: To reduce starting problems, add fuel stabilizer to the fuel all season, mixing it with fuel less than 30 days old; run the machine dry before storing it for more than 30 days.Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.
Filling the Fuel Tank
Fuel tank capacity: 37.8 L (10 US gallons)
-
Park the machine on a level surface, shut off the engine, and allow the engine to cool.
-
Clean around the fuel-tank cap and remove it.
-
Fill the tank to approximately 25 mm (1 inch) below the top of the tank (the bottom of the filler neck).
Important: This space in the tank allows the fuel to expand. Do not fill the fuel tank completely full.
-
Install the fuel-tank cap securely.
-
Wipe up any spilled fuel.
Checking the Engine-Oil Level
The engine is shipped with high-quality oil in the crankcase; however, the oil level must be checked before and after the engine is first started.
Crankcase capacity is approximately 1.9 L (2 US qt) with the filter.
Note: The best time to check the engine oil is when the engine is cool before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the Add mark on the dipstick, add oil to bring the oil level to the Full mark. Do not overfill. If the oil level is between the Full and Add marks, you do not need to add oil.
-
Park the machine on a level surface, shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
-
Clean around the oil dipstick so that dirt cannot fall into the filler hole and damage the engine (Figure 8).
-
Remove the dipstick, wipe it clean, and install it until it is fully seated.
-
Remove the dipstick and check the oil level on the dipstick.
The oil level should be up to the Full mark on the metal end of the dipstick.
-
If the oil level is below the Full mark, remove the filler tube cap and add oil until the level reaches the Full mark on the dipstick (Figure 9).
Important: Do not overfill the crankcase with oil because this may cause engine damage. Do not run the engine with oil below the low mark because the engine may be damaged as a result.
-
Install the filler tube cap and dipstick.
During Operation Safety
-
The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

Slope Safety
Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death.
-
Review the traction unit specifications to ensure that you do not exceed its slope capabilities.
-
Survey the site to determine which slopes are safe for operating the machine and establish your own procedures and rules for operating on those slopes. Always use common sense and good judgment when performing this survey.
-
If you feel uneasy operating the machine on a slope, do not do it.
-
Keep all movement on slopes slow and gradual. Do not suddenly change the speed or direction of the machine.
-
Avoid operating the machine on wet terrain. Tires may lose traction. A rollover can occur before the tires lose traction.
-
Travel straight up and down a slope.
-
Turning while going up or down a slope can be dangerous. If you must turn on a slope, do it slowly and cautiously.
-
Heavy loads affect stability on a slope. Carry a reduced load and reduce your ground speed when operating on a slope or if the machine has a full hopper.
-
Avoid starting, stopping, or turning the machine on a slope, especially with a full hopper. Stopping while going down a slope takes longer than stopping on level ground. If you must stop the machine, avoid sudden speed changes, which can cause the machine to tip or roll over.
Starting the Engine
-
Place all the controls in the OFF or DISENGAGED position.
-
Move the throttle lever midway between the SLOW and FAST position.
-
Move the choke lever to the ON position.
Note: Choke is not required when starting a warm engine.
-
Insert the key into the ignition switch and rotate it clockwise to start the engine. Release the key when the engine starts. Regulate the choke to keep the engine running smoothly.
Important: To prevent overheating of the starter motor, do not engage the starter longer than 10 seconds. After 10 seconds of continuous cranking, wait 60 seconds before engaging the starter motor again.
-
Move the throttle lever to the desired engine speed.
-
Pull the flap lever as far forward as possible.
-
Push the reel lever forward until the catch releases, then push it to the rear until the lever hits STOP.
Note: Do not allow the machine to stand still with the rake engaged as turf damage may occur.
Shutting Off the Engine

-
Turn the ignition key to the OFF position and remove the key.
Note: To stop the machine in an emergency, move the ignition switch to the OFF position.
Adjusting the Rake Depth
The flex tip reel should be adjusted to ensure that the rake tips slightly touch surface but do not penetrate the turf.
-
Position the machine on a level surface.
-
Turn the depth-adjustment bolt until the rake slightly contacts the top of the turf grass. If a broom is installed, slight contact should be made with the surface. When the broom is operating, the contact width surface should be about 25 mm (1 inch) wide across the entire length of the broom (Figure 10).
-
Repeat the procedure on the opposite side of the machine.
After Operation Safety
-
Park the machine on a firm, level surface. Avoid soft ground because the jack stand could sink and cause the machine to tip over.
-
Shut off the engine and remove the key. Wait for all movement to stop and allow the machine to cool before adjusting or cleaning it.
-
Do not disconnect the machine from the traction unit on hills or without engaging the front jack.
-

Inspecting and Cleaning Up after Operation
After sweeping, thoroughly clean and wash the machine. Air out the dry hopper. After cleaning, inspect the machine for possible damage to the mechanical components and blower.
Important: When towing the machine for long distances, fasten the gauge wheel arm securely to the machine frame with the transport hooks. Allowing the gauge wheel arm to fall to the ground may damage the machine.
Operating Tips
General
-
Before starting to sweep, survey area to determine the best direction to sweep.
Note: To maintain a straight line when sweeping, sight of an object in the foreground.
-
Always try to make a long, continuous run with a slight overlap on the return run.
-
On turf areas, the flex tip reel picks up twigs, clippings, leaves, pine needles and cones, small debris (beverage cans, small bottles, paper plates, etc.).
-
The rake teeth are made of flexible nylon and easily changed. To prevent damage, the rake is protected from solid obstructions by spring action. The nylon teeth do not mar bronze, stone markers, sidewalks or pavement.
-
Because of its unique design, the machine also grooms the turf. The flex tip reel combs through and lifts grass for a uniform cut when mowed. As it cleans, the light scarifying action increases water and pesticide penetration, thus reducing the need for renovation.
Important: Do not make sharp turns when using the thatching reel to prevent damaging the turf.
Important: Do not operate the machine while the reel is turning and in the raised position. Damage to the rake and tires may result if teeth come in contact with tires.
-
To empty the hopper, pull the tailgate latch rope.
