OPERATING INSTRUCTIONS

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 a 30° angle to the ground (Fig. 24).
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
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. 23) while operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended. Line release
becomes more difficult as the cutting line becomes shorter.
Fig. 23
Each time the head is bumped, about 1 inch (25.4 mm) of trimming line is
released. A blade in the cutting attachment shield will cut 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 line release is attempted in tall grass,
the engine may stall.
NOTE: Do not rest the Bump Head™ on the ground while the unit is running.
HOLDING THE TRIMMER
Before operating the unit, stand in the
operating position (Fig. 22). Check for
the following:
• The operator is wearing eye
protection and proper clothing
• With a slightly-bent right arm, the
operator’s right hand is holding the
shaft grip
• The operator’s left arm is straight,
the left hand holding the J-handle
• The unit is at waist level
• The cutting attachment is parallel to
the ground and easily contacts the
grass without the need to bend over
Once you are in the operating position,
hook the shoulder strap to the unit.

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.
• Cut from left to right whenever possible. Cutting to the right 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 forward-backward or side-to-side motion. Cutting
shorter lengths produces the best results.
• Trim only when grass and weeds are dry.
• The life of your cutting line is dependent upon:
— Proper adherence of trimming techniques (explained above)
— What vegetation is 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.
WARNING: Always wear eye, hearing, foot and body
protection to reduce the risk of injury when operating this unit.
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.
