Hold the shaft grip with the right hand. Keep the right arm
slightly bent.

Keep the cutting head parallel to the ground so that it easily _ ,_

ADJUSTING THE TRiMMiNG LiNE LENGTH
This unit is equipped with a Bump Head. Trimming line can be
released from the cutting head without stopping the engine.
To release more line, lightly tap the bump knob on the ground (Fig. 10)
while operating the unit at high speed. For best results, tap the bump
knob on bare ground or hard soil. Attempting to release line in tall
grass may stall the engine.
NOTE: Do not rest the cutting head on the ground while the unit is
running.
Each time the bump knob is tapped, about 1 inch (25.4 mm) of
trimming line is released.
NOTE: Always keep the trimming line fully extended. Line release
becomes more difficult when the cutting line gets shorter.
A blade in the cutting head shield will cut the line to the proper
length if any excess line is released.
CAUTION:
Do not remove or alter the line cutting blade
assembly. Excessive line length will make the unit
overheat. This may lead to serious personal injury or
damage to the unit.

Cut from left to right whenever possible. This improves the unit's

Entanglement with foreign matter
Normal line fatigue
Attempting to cut thick vegetation
Forcing the line into objects such as walls or fence posts

unit so that the cutting head is at a 30 ° angle to the ground (Fig. 11).
