HOLDING THE TRIMMER
Before operating the unit, stand in the
operating position (Fig. 10). Check for the
following:
• The operator is wearing eye protection and

proper clothing

• With a slightly-bent right arm, the

operator’s right hand is holding the shaft
grip

• The operator’s left arm is straight, the left

hand holding the handle

• The unit is at waist level
• The cutting attachment is parallel to the

ground and easily contacts the grass
without the need to bend over

BUMP KNOB LINE ADVANCE
Tap the bump knob on the ground to advance the cutting line when
necessary.
TIPS FOR BEST TRIMMING RESULTS
• For best trimming results, operate unit with throttle control fully

squeezed.

• 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.

• Cut from right to left.

WARNING:

Always wear eye, hearing, foot and body

protection to reduce the risk of injury when operating
this unit.

30°

• 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. It is normal for
some line breakage to occur from regular use.
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. 11).
