Trimmer Operating Position

Before using the Trimmer, check the following:

1.

The Trimmer should be on the operator’s right
side.

2.

The operator’s right hand should be holding the
shaft grip, with his or her fingers on the throttle
trigger.  The right arm should be slightly bent.

3.

The left hand should be holding the loop handle
with the fingers and thumb fully enclosed around
the grip.  The left arm should be extended.
Reposition the loop handle up or down the drive-
shaft if necessary for a comfortable position.

4.

The Trimmer weight should be evenly distributed
between the arms.  The trimmer head should be
near and parallel to the ground.

5.

Accelerate and hold the engine at cutting speed
before entering the material to be cut.

6.

Always release the throttle trigger and allow the
engine to return to idle speed when not cutting.

7.

Stop the Trimmer engine when moving between
work sites.

• If the trimmer head becomes jammed, stop the

engine immediately.

• Make certain all moving parts have stopped and

disconnect the spark plug before inspecting the
equipment for damage.

• Never use a String Trimmer that has chipped,

cracked or broken trimmer head.

Cutting with Nylon Trimmer Line

• The tip of the line does the cutting.  The line

should stay extended while cutting.

• Do not force the line into the material.  Forcing

the line will cause it to slap against the material,
increasing line usage and causing poor cutting
results.

CAUTION

• Always wear gloves and protective cloth-

ing when operating the String Trimmer.
