WARNING!
The cutting attachment must NEVER
rotate at engine idle! If the idle speed
cannot be adjusted by the procedure
described here, return the unit to your
Shindaiwa dealer for inspection.
1. Place the unit on the ground, then start
the engine, and then allow it to idle 2-3
minutes until warm.
2. If the attachment rotates when the
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise. See Figure 26.
3. If a tachometer is available, the engine idle
speed should be final adjusted to 2,750
(±250) RPM (min -1 ).
4. Carburetor fuel mixture adjustments are
preset at factory on units with emission
control systems and cannot be serviced
in the field.
The engine must return to idle speed
whenever the throttle lever is released.
Idle speed is adjustable, and must be set
low enough to permit the engine clutch to
disengage the cutting attachment.

required for use with a grass trimmer, a
shoulder strap can increase operator comfort
during extended periods of operation. See
Figure 29.
Grass Trimming
Using a Blade
WARNING!
Always wear a shoulder strap when op­
erating this unit with a blade. A shoul­
der strap is also recommended when
using trimmer line.
NOTE:
Using a shoulder strap with a brush-cutter
allows you to maintain proper control of the
unit and reduces fatigue during extended
operation.

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.
Checking Unit Condition
NEVER operate the unit with the cut-
ting attachment shield or other protective
devices (harness, ignition switch, blade
retention clip, etc.) removed!
AlwAys make sure the cutting attach-
ment is properly installed and firmly tight-
ened before operation.
NEVER use a cracked or warped cutting
attachment: If a properly installed attach-
ment vibrates, replace the attachment with
new one and
re-check.
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 equip-
ment.
WARNING!
A cutting attachment shield or other
protective device is no guarantee of
protection against ricochet. YOU MUST
ALWAYS GUARD AGAINST FLYING
DEBRIS!
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer,
brushcutter, or lawn edger. Do not make
modifications to this unit without the writ-
ten approval of Shindaiwa, Inc.
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.
NEVER cut with a dull blade. Doing so will
increase the risk of blade thrust and may
also cause equipment damage.
