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. 19).

MAINTENANCE AND REPAIR INSTRUCTIONS
WARNING: To prevent serious injury, never
perform maintenance or repairs with unit running.
Always service and repair a cool unit. Disconnect
the spark plug wire to ensure that the unit cannot
start.
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.
• 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 explained trimming techniques
• 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.
FIXED LINE INSTALLATION
Always use original equipment
manufacturer 0.105 inch (2.67 mm)
replacement line. Lines other than
those specified may make the
engine overheat or fail.
To install the trimming line:
1.
Insert each end of the
replacement line into the holes
on either side of retention
hook (Fig. 20).
2. Push the ends through until
they stick out of the sides of
the head (Fig. 21).

WARNING: Never use metal-reinforced line, wire,
chain, or rope. These can break off and become
dangerous projectiles.
3. Pull the ends through making
sure that the ends are of
equal length and the middle
of the line is centered
between the insertion holes
(Fig. 22).
4. If the ends are not of equal
length, push the longer end
back through the head part
way and pull the shorter end to
compensate. Repeat until both
ends are the same length.
