SAFETY INFORMATION
ENGINE SAFETY
DANGER

The engine fuel exhaust gases contain poisonous carbon
monoxide. This gas is colorless and odorless, and can
cause death if inhaled.

The engine of this equipment
requires an adequate free flow
of cooling air. NEVER operate
this equipment in any enclosed
or narrow area where free flow
of the air is restricted. If the air
flow is restricted it will cause


DO NOT place hands or fingers inside engine
compartment when engine is running.

NEVER operate the engine with heat shields or
guards removed.

DO NOT remove the engine oil drain plug
while the engine is hot. Hot oil will gush
out of the oil tank and severely scald any
