Operator Safety

Safe Handling of Gasoline
(Continued From Previous Page)

6. DO NOT fill fuel containers inside a vehicle or on a truck
or trailer bed with a plastic liner. Always place the contain-
ers on the ground away from the vehicle before filling.
7. Remove gas-powered equipment from the vehicle or
trailer and refuel it on the ground.  If this is not possible,
then refuel equipment using a portable container, rather
than a gasoline dispenser nozzle.
8. DO NOT start gas powered equipment in enclosed vehi-
cles or trailers.
9. 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
10. If fuel is spilled on clothing, change clothing
immediately.
11. DO NOT overfill a fuel tank. Replace fuel cap and tighten
securely.

Operation

1. DO NOT put hands or feet near or under rotating parts.
Keep clear of discharge area while engine is running.
2. STOP engine when crossing gravel drives, walks, or
roads, and under any conditions where thrown objects
might be a hazard.
3. Mow only in daylight or good artificial light.
4. DO NOT operate mower while under the influence of
alcohol or drugs.
5. After striking a foreign object or if mower vibrates
abnormally, STOP the engine, disconnect and secure spark
plug wire. Inspect the mower for any damage and repair the
damage before starting.
6. DO NOT mow near drop offs, ditches or embankments.
Operator could lose footing or balance.
7. STAY ALERT for holes and other hidden hazards. Tall
grass can hide obstacles. Keep away from ditches,
washouts, culverts, fences and protruding objects. 
8. DO NOT mow on wet grass. Always be sure of your
footing. Keep a firm hold on the handle and walk, never run.
Slipping could cause injury.
9. ALWAYS stay behind handle when engine (motor) is
running.
10. DO NOT leave the machine with the engine running.
STOP BLADE and STOP ENGINE before leaving the opera-
tors position for any reason.
11. Before cleaning, repairing or inspecting make certain
engine, blade and all moving parts have STOPPED.
Disconnect and secure spark plug wire away from plug to
prevent accidental starting.
12. STOP engine and wait until the blade comes to com-
plete STOP before removing grass bag and/or clearing
grass.

Operation
(Continued From Previous Column)

13. DO NOT operate mower without the entire grass catch-
er, or guards in place discharge guard, rear guard or other
safety devices in place and working. DO NOT point dis-
charge at people, passing cars, windows or doors.
14. DO NOT discharge material against a wall or obstruc-
tion. Material may ricochet back towards the operator.
15. Slow down before turning.
16. Watch out for traffic when near or crossing roadways.
17. DO NOT operate engine in enclosed areas.  Engine
exhaust gases contain carbon monoxide, a deadly poison.
18. Only use accessories approved by the manufacturer.
See manufacturer’s instructions for proper operation and
installation of accessories.

Maintenance and Storage

1. DO NOT store mower or fuel container inside where
fumes may reach an open flame, spark or pilot light such as
in a water heater, furnace, clothes dryer or other gas appli-
ance. Allow engine to cool before storing machine in an
enclosure. Store fuel container out of reach of children in a
well ventilated, unoccupied building.
2. Keep mower and engine free of grass, leaves or excess
grease to reduce fire hazard and engine overheating.
3. When draining fuel tank, drain fuel into an approved
container outdoors and away from open flame.
4. Keep all bolts, especially blade bolts, nuts and screws
properly tight. Check that all cotter pins are in proper
position.
5. Always provide adequate ventilation when running
engine. Engine exhaust gases contain carbon monoxide, a
deadly poison.
6. Service engine and make adjustments only when engine
is stopped. Removed spark plug wire from spark plug and
secure wire away from spark plug to prevent accidental
starting.
7. DO NOT change engine governor speed settings or
overspeed engine.
8. Check grass bag assembly frequently for wear or
deterioration to avoid thrown objects and exposure to
moving parts. Replace with new bag if loose seams or tears
are evident. Replace slider or bag adapter if broken or
cracked.
9. Mower blades are sharp and can cut. Wrap the blades or
wear heavy leather gloves and use CAUTION when handling
them.
10. DO NOT test for spark by grounding spark plug next to
spark plug hole; spark plug could ignite gas exiting engine.
11. Have machine serviced by an authorized dealer at least
once a year and have the dealer install any new safety
devices.
12. Use only genuine replacement parts to assure that
original standards are maintained.
