Starting and Stopping Engine
Refer to the Engine Operator’s Manual packed with
your string trimmer for instructions on starting and
stopping the engine.
Using Your String Trimmer
Be sure trimming area is clear of stones, sticks, wire,
or other objects which could damage the string
trimmer or engine. Such objects could be accidently
thrown by the trimmer in any direction and cause
serious personal injury to the operator and others.
WARNING: The operation of any string
trimmer can result in foreign objects
being thrown into the eyes, which can
damage your eyes severely. Always wear
safety glasses while operating the string
trimmer, or while performing any
adjustments or repairs on it.

Figure 3-1
• The string trimmer is designed with the spindle
offset to the left side, allowing the operator to
trim along a fence, landscaping, or a house to
his or her’s right side without having to make
any adjustments to the machine.
• Operate the string trimmer at a slower walking
speed when trimming tall, thick weeds or grass.
• Clean the underside of the trimmer after each
use to remove any debris build up.
WARNING: Shut the engine off and wait
until the trimmer head comes to a
complete stop before cleaning the
discharge area. The trimmer head
continues to rotate for a few seconds after
the trimmer head control is released.
• Do not trim on excessively steep slopes. If a
slope is difficult to stand on, do not trim. Do
not trim on slopes when the ground is slippery
or wet. Trim across the face of a slope, not up
and down.
To use the Drive Control (if equipped):
• Once the engine is running, squeeze the drive
control lever against the upper handle to
propel the string trimmer.
• Release the single lever drive control to slow
down or stop the string trimmer from driving.
CAUTION: While operating the string trimmer, do not
allow the spindle to contact a concrete, asphalt, or
gravel surface. Doing so will result in premature wear.
Changing the Trimmer Line
To ease in removing worn trimmer line, change
the trimmer line before it becomes too short (i.e.
approximately half its original length).
1. Remove the worn trimmer line from the
spindle.
2. Fold the replacement trimmer line in half and
insert both ends through the loop near the
edge of the spindle.
3. Pull the ends of the trimmer line through the
loop until the line is securely beneath the
metal tab.
4. Cross the line ends and pull each tightly to
secure the trimmer line in place. See Figure 3-3.
