spilled gasoline before starting the engine as it

may cause a fire or explosion.

c. Extinguish all cigarettes, cigars, pipes and other

sources of ignition.

vapors will accumulate in the area.

e. Never store the machine or fuel container inside

where there is an open flame or spark such as a
gas hot water heater, space heater, clothes

dryer or furnace.

Never run your machine in an enclosed area as the
exhaust from the engine contains carbon monoxide,
which is an odorless, tasteless and deadly poisonous

gas.
To reduce fire hazard, keep engine and muffler free of

leaves, grass, and other debris build-up. Clean up
fuel and oil spillage. Allow unit to cool at least 5

minutes before storing.

Before cleaning, repairing, or inspecting, make certain
the impeller and all moving parts have stopped.

Disconnect the spark plug wire and keep wire away
from spark plug to prevent accidental starting. Do not

use flammable solutions to clean air filter.

Check the blade and engine mounting screws at

frequent intervals for proper tightness. Also visually

inspect blades for wear and/or damage (e.g., bent,

cracked). Replace with blades which meet original

equipment specifications.

Keep all nuts, bolts, and screws tight to be sure the

equipment isin safe working condition.

Never tamper with safety devices. Check their proper

operation regularly.

After stdking e foreign object, immediately stop the

engine, disconnect the spark plug wire from the spark

plug, end thoroughly inspect the unit for any damage.

Repair damage before starting and operating unit.
