OPERATING INSTRUCTIONS
HOLDING THE TRIMMER
Each time the head is bumped, about 1 inch (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.
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.
15). Check for the following:
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
•
•
Keep the cutting attachment parallel to the ground.
Do not force the cutting attachment. Allow the tip of the line
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.
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
The cutting attachment is parallel to the ground and easily
contacts the grass without the need to bend over
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. 16)
while operating the trimmer at high speed.
•
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.

NOTE: Always keep the trimming line fully extended. Line
release becomes more difficult when the cutting line
gets shorter.
