Checking Unit Condition; Shoulder Strap; Cutting Grass With A Trimmer Head - Shindaiwa 81601 Owner's/Operator's Manual

Checking Unit Condition

Use only authorized Shindaiwa parts and ac-
cessories with your Shindaiwa trimmer. Do
not make modifications to this unit without
written approval from Shindaiwa, Inc.
WARNING!
A cutting attachment shield
or other protective device is
no guarantee of protection against ric-
ochet. YOU MUST ALWAYS GUARD
AGAINST FLYING DEBRIS!

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 3.
Cutting Grass—Units Equipped with a Trimmer Head
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.
ALWAYS make sure the cutting attachment
is properly installed and firmly tightened
before operation.
NEVER use a cracked or warped cutting at-
tachment: replace it with a serviceable one.
ALWAYS make sure the cutting attachment
fits properly into the appropriate attachment
holder. If a properly installed attachment
vibrates, replace the attachment with new
one and re-check.

ting grass.

ALWAYS stop the engine immediately and
check for damage if you strike a foreign
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 damage the
engine.
NEVER operate a unit with worn or dam-
aged fasteners or attachment holders.
NEVER operate the unit with the cutting at-
tachment shield or other protective devices
removed!
T231X Operating With A Blade
-
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.
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 4.
Edging
Tilt the handle
about 100° to the left
(from horizontal)
and move forward,
holding the trimmer
vertically as shown
in Figure 5.
