ting attachment shield or other protective

Edging
Tilt the handle about
100° to the left (from
horizontal) and move
forward, holding the
trimmer vertically as

Your Shindaiwa unit may be equipped with one
of several Shindaiwa trimmer head models,
each with features for specific applications
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 man-
ually 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 clearing
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.

CAUTION!
Operation of trimmer without a cutting at-
tachment shield and using excessive line
length can lead to premature clutch failure.
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer.
Do not make modifications to this unit with-
out written approval from Shindaiwa, Inc.
ALWAYS make sure the cutting attach-
ment is properly installed and firmly tight-
ened before operation.
NEVER use a cracked or warped cutting at-
tachment: replace it with a serviceable one.
ALWAYS make sure the cutting attach-
ment fits properly into the appropriate
attachment holder. If a properly installed
attachment vibrates, replace the attach-
ment with new one and re-check.
ALWAYS stop the engine immediately
and check for damage if you strike a for-
eign object or if the unit becomes tangled.
Do not operate with broken or damaged
equipment.
NEVER allow the engine to run at high
RPM without a load. Doing so could dam-
age the engine.
NEVER operate a unit with worn or dam-
aged fasteners or attachment holders.
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.
WARNING!
Always wear a shoulder strap
or harness when operating this unit.
Using a harness with a brushcutter
allows you to maintain proper control
of the unit and reduces fatigue during
extended operation.
Figure 25
IMPORTANT!
Adjust the shoulder strap so the shoulder pad
rests comfortably on the off-side shoulder and
the cutting path of the cutting attachment
is parallel to the ground. Make sure all
hooks and adjustment devices are secure.
Double Shoulder Harness
(optional accessory)
Adjust the double shoulder harness straps
so the shoulder pads rest comfortably
on the shoulders and the cutting path of
the blade is parallel to the ground. Make
sure all hooks and adjusting devices are
secure.

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 hori-
zontal. See Figure 24.
