HOLDING THE TRIMMER
WARNING:
Always wear eye, hearing, foot and
body protection to reduce the risk of injury when
operating this unit.
Before operating the unit, stand in the operating position (Fig.
12). Check for the following:
• The operator is wearing eye protection and proper clothing
• With a slightly-bent right arm, the operator's hand is
holding the shaft grip
• The operator's left arm is straight, the left hand holding the
D-handle
• The unit is at waist level
• The cutting head is parallel to the ground and easily contacts
the grass without the need to bend over
ADJUSTING TRIMMING LINE LENGTH
The Bump Head™ cutting head allows you to release trimming
line without stopping the engine. To release more line, lightly tap
the cutting head on the ground (Fig. 13) 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.
Each time the head is bumped, about 1 inch (25.4 mm) of
trimming line releases. A blade in the cutting head 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.

OPERATING INSTRUCTIONS

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 head parallel to the ground.
• Do not force the cutting head. 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 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 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:
• 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.
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences and more.
Rotate the whole unit so that the cutting head is at a 30° angle
to the ground (Fig. 14).
