TIPS FOR BEST TRIMMING
(Fig. 19)
◾
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 efficiency 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.
◾
Wire and picket fences can cause extra string wear or breakage. Stone and brick
walls, curbs, and wood may wear strings rapidly.
◾
Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can
easily be damaged by the strings.
ADJUSTING THE CUTTING LINE
LENGTH
The Line-IQ feeding trimmer head is
equipped with advanced technology.
If either end of the cutting line wears less
than 7 inches (18cm) during trimming,
trimmer head will release cutting line
automatically, and the extra part of the
cutting line will be cut off by the line-
cutting blade (Fig. 20).
NOTICE: No need to tap the trimmer head to release the cutting line. If you feel a
