WARNING:

Always shut off engine before fueling. Never add fuel to
a machine with a running or hot engine. Move at least
30 ft. from refueling site before starting engine. Do not
smoke!

OPERATING THE TRIMMER

See Figure 15.

¿k WARNING:

Always position the unit on the operator’s right side. The

use of the unit on the operator’s left side will expose

the user to hot surfaces and can result in possible burn

injury.

FILLING TANK

■ Clean surface around fuel cap to prevent

contamination.

■ Loosen fuel cap slowly. Rest the cap on a clean

surface.

■ Carefully pour fuel into the tank. Avoid spillage.

■ Prior to replacing the fuel cap, clean and inspect the

gasket.

■ Immediately replace fuel cap and hand tighten. Wipe up

any fuel spillage.

NOTE: It is normal for smoke to be emitted from a new
engine after first use.

WARNING:

To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.

Flold the trimmer with your right hand on the rear handle and

your left hand on the front handle. Keep a firm grip with both
hands while in operation. Trimmer should be held at a com­
fortable position with the rear handle about hip height.

Always operate trimmer at full throttle. Cut tall grass from
the top down. This will prevent grass from wrapping around
the shaft housing and string head which could cause
damage from overheating. If grass becomes wrapped around
the string head, STOP TFIE ENGINE, disconnect the spark

plug wire, and remove the grass. Prolonged cutting at partial

throttle will result in oil dripping from the muffler.
