• Contact with the moving blade will cause serious injury. Do not put your fingers under the housing when adjusting the cutting height.
Fuel Safety
• Fuel is extremely flammable and highly explosive.
A fire or explosion from fuel can burn you and others and can damage property.
– To prevent a static charge from igniting the fuel, place the container and/or machine directly on the ground before filling, not in a vehicle or on an object.
– Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.
– Do not handle fuel when smoking or around an open flame or sparks.
– Do not remove the fuel cap or add fuel to the tank while the engine is running or hot.
– If you spill fuel, do not attempt to start the engine. Avoid creating a source of ignition until the fuel vapors have dissipated.
– Store fuel in an approved container and keep it out of the reach of children.
• Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.
Filling the Fuel Tank
• For best results, use only clean, fresh, 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. Using unapproved gasoline is not covered under the product warranty.
• Do not use gasoline containing methanol.
• Do not store fuel either in the fuel tank or in fuel containers over the winter unless fuel stabilizer has been added to the fuel.
• Do not add oil to gasoline.
Important: To reduce starting problems, add fuel stabilizer to the fuel all season, mixing it with gasoline less than 30 days old.

Operating Tips
General Mowing Tips
• Inspect the area where you will use the machine and remove all objects that the machine could throw.
• Avoid striking solid objects with the blade. Never deliberately mow over any object.
• If the machine strikes an object or starts to vibrate, immediately shut off the engine, disconnect the wire from the spark plug, and examine the machine for damage.
• For best performance, install a new blade before the cutting season begins.
• Replace the blade when necessary with a Toro replacement blade.
• If there are more than 13 cm of leaves on the lawn, mow at a higher cutting height and then again at the desired cutting height.
• Slow down your mowing speed if the machine does not cut the leaves finely enough.
Cutting Grass
• Cut only about a third of the grass blade at a time. Do not cut below 51 mm unless the grass is sparse or it is late fall when grass growth begins to slow down.
• When cutting grass over 15 cm tall, mow at the highest cutting height setting and walk slower; then mow again at a lower setting for the best lawn appearance. If the grass is too long, the machine may plug and cause the engine to stall.
• Wet grass and leaves tend to clump on the yard and can cause the machine to plug or the engine to stall. Avoid mowing in wet conditions.
• Be aware of a potential fire hazard in very dry conditions, follow all local fire warnings, and keep the machine free of dry grass and leaf debris.
• Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization.
• If the finished lawn appearance is unsatisfactory, try 1 or more of the following:
– Replace the blade or have it sharpened.
– Walk at a slower pace while mowing.
– Raise the cutting height on your machine.
– Cut the grass more frequently.
– Overlap cutting swaths instead of cutting a full swath with each pass.
Cutting Leaves
• After cutting the lawn, ensure that half of the lawn shows through the cut leaf cover. You may need to make more than a single pass over the leaves.

Changing the Engine Oil
Changing the engine oil is not required, but if you desire to change the oil, use the following procedure.
Engine oil capacity: 0.55 L
Oil viscosity: SAE 30 or SAE 10W-30 detergent oil
API service classification: SJ or higher
Note: Run the engine a few minutes before changing the oil to warm it. Warm oil flows better and carries more contaminants.
1.
Move the machine to a level surface.
2.
Refer to
Preparing for Maintenance (page 15)
.
3.
Remove the dipstick by rotating the cap
counterclockwise and pulling it out ( Figure 24 ).
6.
Carefully pour about 3/4 of the engine capacity of oil into the oil-fill tube.
7.
Wait about 3 minutes for the oil to settle in the engine.
8.
Wipe the dipstick clean with a clean cloth.
9.
Insert the dipstick into the oil-fill tube, then remove the dipstick.
10.
Read the oil level on the dipstick (
).
• If the oil level on the dipstick is too low, carefully pour a small amount of oil into the oil-fill tube, wait 3 minutes, and repeat steps
8 through 10 until the oil on the dipstick is at the correct level.
• If the oil level on the dipstick is too high, drain the excess oil until the oil on the dipstick is at the correct level.
Important: If the oil level in the engine is too low or too high and you run the engine, you may damage the engine.
11.
Install the dipstick securely.
12.
Recycle the used oil properly.
