Your Shindaiwa unit may be equipped with
one of several Shindaiwa trimmer head mod-
els, each with features for specific applica-
tions and/or operational requirements.
NOTE:
For proper operation, always refer to the
instructions accompanying the trimmer
head being used. Available trimmer head
styles include:
n Semi-automatic. Trimmer line is
indexed when the operator taps the
trimmer head on the ground during
operation.
n Manual. The operator indexes line
manually with the grass trimmer
stopped.
n Fixed. The operator must stop the unit
and add new lengths of trimmer line
manually.
n Flail. This device, designed for clear-
ing weeds and light brush, features
three nylon blades attached to the head
by pivots.
NOTE:
Additional hardware may be required to
mount the Fixed Line or the Flail type trim-
mer heads.
Cutting Grass—Units Equipped with a Trimmer Head
CAUTION!
Operation at low RPM can lead to
premature clutch failure.
Trimming and Mowing Grass
Hold the trimmer so the trimmer head is
angled slightly into the area to be cut. To
ensure maximum trimmer-line service life,
cut only with the tip of the trimmer line.
Cut grass by
swinging the
trimmer from left
to right. Keep the
trimmer head
horizontal.
See Figure 24.
Edging
Tilt the handle
about 100° to the left
(from horizontal)
and move forward,
holding the trimmer
vertically as shown
in Figure 25.

CAUTION!
Operation of trimmer without a cutting
attachment shield and using exces-
sive line length can lead to premature
clutch failure.
CAUTION!
Do not push the rotating line into
trees, wire fences or any material that
could tangle or break line ends.
Engine Operating Speeds
Operate the unit at full throttle while cut-
ting grass.
Figure 24
Shoulder Strap
Adjust the shoulder strap so the shoulder
pad rests comfortably on the off-side
shoulder and the cutting path of the cut-
ting attachment is parallel to the ground.
Make sure all hooks and adjustment
devices are secure.

NOTE:
Although a shoulder strap accessory is not
required for use with a grass trimmer, a
shoulder strap can increase operator com-
fort during extended periods of operation.
See Figure 23.
WARNING!
Always wear a shoulder strap
when operating this unit with
a blade. A shoulder strap is also recom-
mended when using trimmer line.
NOTE:
Using a shoulder strap when operating this
unit with a blade allows you to maintain
proper control of the unit and reduces fatigue
during extended operation.

and check for damage if you strike a
foreign object or if the unit becomes
tangled. Do not operate with broken or
damaged equipment.
n NEVER allow the engine to run at high
