OPERATION

ADVANCING TRIMMER CUTTING LINE

String advance is controlled by tapping the string head on grass while running engine at full throttle.

Run engine at full throttle.

Tap the spool retainer on ground to advance string. The string advances each time the spool retainer is tapped. Do not hold the spool retainer on the ground.

NOTE: The line trimming cut-off blade on the grass deflector will cut the line to the correct length.

If the string is worn too short you may not be able to advance the string by tapping it on the ground. If so, stop the engine and manually advance the string by pushing the spool retainer down while pulling on string(s).

GRASS DEFLECTOR LINE TRIMMING CUT-OFF BLADE

See Figure 8.

The trimmer is equipped with a line trimming cut-off blade on the grass deflector. For best cutting, advance string until it is trimmed to length by the cut-off blade. Advance the string whenever you hear the engine running faster than normal, or when trimming efficiency diminishes. This will maintain best performance and keep the string long enough to advance properly.

OPERATING THE TRIMMER

See Figure 9.

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.

WARNING:

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

Hold 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 comfortable 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 THE ENGINE, disconnect the spark plug wire, and remove the grass. Prolonged cutting at partial throttle will result in oil dripping from the muffler.
