Service
Safe Handling of Gasoline:
Slope Operation
Slopes are a major factor related to slip and fall
accidents which can result in severe injury. Operation
on slopes requires extra caution. If you feel uneasy on a
slope, do not mow it. Before operating this unit on a
slope or hilly area, use the slope gauge on page 6 to
measure slopes. If the slope is greater than 15 degrees,
do not mow it.
1. To avoid personal injury or property damage use
extreme care in handling gasoline. Gasoline is
extremely flammable and the vapors are explosive.
Serious personal injury can occur when gasoline is
spilled on yourself or your clothes which can ignite.
2. Wash your skin and change clothes immediately.
3. Use only an approved gasoline container.
4. 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.
5. If possible, remove gas-powered equipment from
the truck or trailer and refuel it on the ground. If this
is not possible, then refuel such equipment on a
trailer with a portable container, rather than from a
gasoline dispenser nozzle.
Do:
1. Mow across the face of slopes; never up and down.
Exercise caution when changing direction.
2. Watch for holes, ruts, rocks, hidden objects, or
bumps which can cause you to slip or trip. Tall
grass can hide obstacles.
3. Always be sure of your footing. A slip and fall can
cause serious personal injury. If you feel you are
losing your balance, release the blade control
handle immediately, and the blade will stop rotating
within 3 seconds.
6. 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.
7. Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
Do Not:
1. Do not mow near drop-offs, ditches or
embankments, you could lose your footing or
balance.
8. Never fuel machine indoors because flammable
vapors will accumulate in the area.
4

9. Never remove gas cap or add fuel while the engine
is hot or running. Allow engine to cool at least two
minutes before refueling.
10. Never over fill fuel tank. Fill tank to no more than ½
inch below bottom of filler neck to provide space for
fuel expansion.
11. Replace gasoline cap and tighten securely.
12. If gasoline is spilled, wipe it off the engine and
equipment. Move unit to another area. Wait 5
minutes before starting the engine.
13. Never store the machine or fuel container inside
where there is an open flame, spark or pilot light as
on a water heater, space heater, furnace, clothes
dryer or other gas appliances.
lead to improper performance and compromise
safety!”
4. Mower blades are sharp and can cut. Wrap the
blade or wear gloves, and use extra caution when
servicing them.
5. Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
6. Never tamper with safety devices. Check their
proper operation regularly.
7. After striking a foreign object, stop the engine,
disconnect the spark plug wire and ground against
the engine. Thoroughly inspect the mower for any
damage. Repair the damage before starting and
operating the mower.
14. To reduce fire hazard, keep mower free of grass,
leaves, or other debris build-up. Clean up oil or fuel
spillage and remove any fuel soaked debris.
15. Allow a mower to cool at least 5 minutes before
storing.
8. Never attempt to make a wheel or cutting height
adjustment while the engine is running.
9. Grass catcher components, discharge cover, and
trail shield are subject to wear and damage which
could expose moving parts or allow objects to be
thrown. For safety protection, frequently check
components and replace immediately with original
equipment manufacturer’s (O.E.M.) parts only,
listed in this manual. “Use of parts which do not
meet the original equipment specifications may
lead to improper performance and compromise
safety!”
10. Do not change the engine governor setting or
overspeed the engine. The governor controls the
maximum safe operating speed of the engine.
11. Maintain or replace safety and instruction labels, as
necessary.
General Service:
1. Never run an engine indoors or in a poorly
ventilated area. Engine exhaust contains carbon
monoxide, an odorless and deadly gas.
2. Before cleaning, repairing, or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire and
ground against the engine to prevent unintended
starting.
3. Check the blade and engine mounting bolts at
frequent intervals for proper tightness. Also,
visually inspect blade for damage (e.g., bent,
cracked, worn) Replace blade with the original
equipment manufacture’s (O.E.M.) blade only,
listed in this manual. “Use of parts which do not
meet the original equipment specifications may

carburetor may be required to compensate for
differences in fuel, temperature, altitude and load.
Adjusting Cutting Height

relative position. For rough or uneven lawns, move the
height adjustment lever to a higher position. This will
