2-Cycle Gas Trimmer/Brushcutter Operator's Manual

12
HOLDING THE TRIMMER
Before operating the unit, stand in the operating position
(Fig. 19). 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.
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. 20)
while operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult as the cut-
ting line becomes shorter.
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. 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.
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
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.
