a
well ventilated, unoccupied
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.
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. DO NOT leave the machine with the engine
running. STOP BLADE and STOP ENGINE before

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.
11. STOP engine and wait until the blade comes to
complete STOP before removing grass bag
and/or clearing grass.
12. DO NOT operate mower without the entire grass
catcher or guards in place. DO NOT point
discharge at people, passing cars, windows or
doors.
13. Slow down before turning.
14. Watch out for traffic when near or crossing
roadways.
15. DO NOT operate engine in enclosed areas.
Engine exhaust gases contain carbon monoxide,
a deadly poison.
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
SNAPPER dealer at least once a year and have
the dealer install any new safety devices.
12. Use only genuine SNAPPER replacement parts to
assure that original standards are maintained.
