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
