DECORATIVE TRIMMING

1. Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences, etc. Use a 30-
degree angle when trimming with this method (Fig. 14).

TIPS FOR BEST TRIMMING RESULTS

1. Hold the cutting line parallel to the ground, and the
cutting head will be at the correct angle.
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 motor.
3. Grass over eight (8) inches (200 mm) should be cut by
working from top to the bottom in small increments to
avoid premature line wear or motor drag.
4. Whenever possible, cut to your left. When cutting to
the left, the unit's cutting efficiency is improved slight-
ly. Also, the clippings are thrown away from the oper-
ator.
5. Slowly move the trimmer into and out of the area being
cut, maintaining the trimmer at the desired cutting
height. This can be either a forward-backward or side-
to-side motion. Maintain top speed for best cutting.
6. Trim only when grass and weeds are dry.
7. The life of your cutting line is dependent upon following
the previously stated trimming techniques, as well as
what is being cut, and where the cutting is being done.
For example, the line will wear faster when trimming
against a foundation wall as opposed to trimming
around a tree. Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds in excess of
the unit's capability.
• Forcing the line into objects such as walls or
fenceposts
MAINTENANCE AND
REPAIR INSTRUCTIONS
INSTALLING A NEW
TRIMMING LINE
The trimming line may be replaced by two different meth-
ods — rewinding the existing reel or installing a convenient
prewound reel.
Rewinding the Existing Reel
To rewind the existing reel you must:
1. Check for the correct line size
2. Remove the existing inner reel
3. Wind the existing reel with the new line
4. Reinstall the existing reel.
The Correct Line to Use
WARNING
Always use genuine Monoflail ®
line. Do not use metal-reinforced line.
It is very important to use the correct size line. Line with a
diameter of 0.065 inches (1.65 mm) must be used. The
motor may overheat or be damaged if you use a larger
line.
Removing the Existing Reel
1. Squeeze the tabs on the Bump Head cover and
remove the cover (see inset in Fig. 15).
2. Remove the existing inner reel and spring (Fig. 15).
