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.
Idle Speed Adjustment
WARNING!
The cutting attachment must
NEVER rotate at engine idle! If the idle
speed cannot be adjusted by the proce-
dure described here, return the trimmer
to your Shindaiwa dealer for inspection.
1. Place the trimmer on the ground, then
start the engine, and then allow it to idle
- 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 15.
. If a tachometer is available, the engine idle
speed should be final adjusted to ,000
(±00) rpm (min -1 ).
4. Carburetor fuel mixture adjustments are
preset at factory and cannot be serviced
in the field.
NEVER operate the unit with the cutting
attachment shield or other protective
devices removed!
Checking Unit Condition
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer. Do
not make modifications to this unit without
written approval from Shindaiwa, Inc.
ALWAYS make sure the cutting attachment
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 attachment
fits properly into the appropriate attachment
holder. If a properly installed attachment
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 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
damaged fasteners or attachment holders.
WARNING!
A cutting attachment shield or
other protective device is no guarantee
of protection against ricochet. YOU
MUST ALWAYS GUARD AGAINST
FLYING DEBRIS!
