WARNING: Gasoline is highly flammable and
precautions:
Store fuel only in containers specifically designed and approved
for the storage of such materials.
Always stop the engine and allow it to cool before filling the
tank. Never remove the fuel tank cap or add fuel when the
engine is hot. Always loosen the fuel tank cap slowly to relieve
any pressure in the tank before fueling.
Always add fuel in a clean, well-ventilated outdoor area where
there are no sparks or flames. DO NOT smoke.
Never operate the unit without the fuel cap securely in place.
Avoid creating a source of ignition for spilled fuel. Wipe up any
spilled fuel from the unit immediately, before starting the unit.
Move the unit at least 30 ft. (9.1 m) from the fueling source and
site before starting the engine. DO NOT smoke.
Never start or run the unit inside a closed room or building.
Breathing exhaust fumes can kill. Operate this unit only in a well
ventilated outdoor area.
m
WHILE OPERATING
Wear safety glasses or goggles that meet current ANSI / ISEA
Z87.1 standards and are marked as such. Wear ear/hearing
protection when operating this unit. Wear a face mask or dust
mask if the operation is dusty.
Wear heavy long pants, boots, gloves and a long sleeve shirt. Do

The cutting head shield must always be in place while operating
the unit. Do not operate the unit without both trimming lines
extended and the proper line installed. Do not extend the
trimming line beyond the length of the shield.
This unit has a clutch. The cutting head remains stationary when
the engine is idling. If it does not, take the unit to a Sears or
other qualified service dealer for an adjustment.
Adjust the handle to provide the best grip, if applicable.
Make sure the attachment is not in contact with anything before
starting the unit.

job. Do not run the unit at high speed when not in use.
Do not force the unit. It will do a better, safer job when used at

debris that could block moving parts.
To reduce fire hazard, replace a faulty muffler and spark arrestor.
Keep the engine and muffler free from grass, leaves, excessive
grease or carbon build up.
