ADJUSTING TRIMMING LINE LENGTH
The bump head cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 6) while operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter.
NOTE: Do not rest the bump head on the ground while the unit is running.
Some line breakage will occur from:
•Entanglement with foreign matter
•Normal line fatigue
•Attempting to cut thick, stalky weeds
•Forcing the line into objects such as walls or fence posts.
CAUTION: Do not remove or alter the line cutting blade assembly. Excessive line length will make the clutch overheat. This may lead to serious personal injury or damage to the unit.
TIPS FOR BEST TRIMMING RESULTS
•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 in. (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.
•Cut from right to left whenever possible. Cutting to the left improves the unit’s cutting efficiency. Clippings are thrown away from the operator.
•Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a
•Trim only when grass and weeds are dry.
•The life of your cutting line is dependent upon:
•Following the trimming techniques
•What vegetation is being cut
•Where vegetation is cut
For example, the line will wear faster when trimming against foundation wall as opposed to trimming around a tree.

Each time the head is bumped, about 1 in. (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.
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more. Rotate the whole unit so that the cutting attachment is at 30° angle to the ground (Fig. 7)
