OPERATING INSTRUCTIONS
ADJUSTING TRIMMING LINE LENGTH
The Bump Head™ allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting head on the ground while operating the trimmer at high speed. See Figure 10.
FIGURE 10
NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as cutting line becomes shorter.
Each time the head is bumped, it releases about 25.4
mm(1 inch) of trimming line. A blade in the string guard cuts the line to the proper length if excess line is released.
For best results, tap the Bump Head™ on bare ground or hard soil. If you attempt to release line in tall grass, the engine may overheat. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.
NOTE: Do not rest the Bump Head™ on the ground while the unit is running.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.
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
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more. Use a

TIPS FOR BEST TRIMMING RESULTS
1.The correct angle for the cutting head is parallel to the ground.
NOTE: Do not rest the Bump Head™ on the ground.2.DO NOT FORCE THE UNIT. Allow the very 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.
3.Grass over 200 mm (8 in.) should be cut by working from top to the bottom in small increments to avoid premature line wear or engine drag.
4.Whenever possible, cut right to left. When cutting to the left, the unit's cutting efficiency is improved slightly. Also, the clippings are thrown away from the operator.
5.Slowly move the trimmer into and out of the area being cut, keeping the trimmer at the desired cutting height. Move either in a
6.Trim only when grass and weeds are dry.
7.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 a foundation wall as opposed to trimming around a tree.
