Engine Idle Adjustment
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
when the throttle is released.
Idle Speed Adjustment
WARNING!
The cutting attachment must
NEVER rotate at engine idle! If the
idle speed cannot be adjusted by the
proceedure described here, have
the unit inspected at an authorized
Shindaiwa dealer.
Place the unit on the ground, then
start the engine and allow it to idle for
-3 minutes until warm.

If the attachment rotates when the
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise. See Figure 1.
.
NOTE:
Carburetor fuel mixture adjustments are
preset at factory on units with emission
control systems and cannot be serviced
in the field.
If a tachometer is available, the
engine idle speed should be final
adjusted to 3,000 (±50) min
-1
(rpm).

Checking Unit Condition
NEVER operate the unit with the cutting
attachment shield or other protective
devices (harness, ignition switch, blade
retention clip, etc.) removed!
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer
or brushcutter. Do not make modifica-
tions to the unit without the written
approval of Shindaiwa, Inc.
WARNING!
A cutting attachment shield
or other protective device is no
guarantee of protection against
thrown objects. YOU MUST ALWAYS
GUARD AGAINST FLYING DEBRIS!
ALWAYS make sure the cutting attach-
ment is properly installed and firmly
tightened before operation.
NEVER use a cracked or warped cutting
attachment: replace it with a serviceable one.
ALWAYS make sure the cutting attach-
ment fits properly into the appropriate
cutter holder. If a properly installed
attachment vibrates, replace the attach-
ment with a 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 equipment.
NEVER allow the engine to operate at
high RPM’s without a load. Doing so
could damage the engine.
NEVER operate a unit with worn or dam-
aged fasteners or attachment holders.
NEVER cut with dull blades. Doing so
will increase the risk of blade thrust and
may also damage your equipment.
