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.
