NOTE: Always keep the trimming line fully extended. Line
release becomes more difficult as cutting line becomes
shorter.
Switch will be in the On position at all times.
1.
2.
Release your hand from the throttle control. Allow the
engine to cool down by idling.
Each time the head is bumped, about 1 inch (25.4 mm) of
trimming line releases. A blade in the cutting attachment shield
will cut the line to the proper length if any excess line is released.
For best results, tap the bump knob on bare ground or hard
soil. If you attempt a line release in tall grass, the engine may
stall. Always keep the trimming line fully extended. Line release
becomes more difficult when the cutting line gets shorter.
Press the On/Off Stop Control in the OFF (O) position and
hold until the unit completely stops running. (Fig. 2)

the clutch overheat. This may lead to serious
personal injury or damage to the unit.
NOTE: Do not rest the Bump Head on the ground while the
unit is running.

Forcing the line into objects such as walls or fence posts
TIPS FOR BEST TRIMMING RESULTS
•
•
•
For best trimming results, operate unit at full throttle.
Keep the cutting attachment parallel to the ground.
Do not force the cutting attachment. Allow the tip of the line to
do the cutting, especially along walls. Cutting with more than the
tip will reduce cutting efficiency and may overload the engine.
•
Cut grass over 8 inches (200 mm) by working from top to
bottom in small increments to avoid premature line wear or
engine drag.
