cleaning plastic parts. Most plastics are susceptible to damage from various types of

Tips for best trimming results
(Fig. 13)
◾
The correct angle for the cutting
attachment is parallel to the ground.
◾
Do not force the trimmer. Allow the
very tip of the line to do the cutting
(especially along walls). Cutting
with more than the tip will reduce
cutting efciency and may overload
the motor.
◾
The cutting height is determined by the distance of the cutting line from the lawn
surface.
◾
Grass over 8 inches (200mm) should be cut by working progressively from top to
the bottom in small increments to avoid premature line wear or motor drag.
◾
Slowly move the trimmer into and out of the area being cut, maintaining the
cutting head position at the desired cutting height. This movement can be either
a forward-backward motion or a side-to-side motion. Cutting shorter lengths
produces best results.
◾
Trim only when grass and weeds are dry.
