Checking Unit Condition

NEVER operate the unit with the cut-
ting attachment shield or other protective
devices removed!
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.
Do not make modifications to this unit with-
out written approval from Shindaiwa, Inc.

7. Operating the throttle will automatically
disengage the fast idle setting.
IMPORTANT!
If the engine fails to start after several at-
tempts with the choke in the closed posi-
tion, the engine may be flooded with fuel.
If flooding is suspected, move the choke
lever to the open position and repeatedly
pull the recoil starter to remove excess
fuel and start the engine. If the engine still
fails to start, refer to the troubleshooting
section of this manual.
When the Engine Starts...
n After the engine starts, allow the engine
to warm up at idle 2 or 3 minutes before
operating the unit.
341020 n After the engine is warm, pick up the
unit and clip on the shoulder harness or
strap. See page 13.
n Advancing the throttle makes the cut-
ting attachment turn faster; releasing
the throttle permits the attachment to
stop turning. If the cutting attachment
continues to rotate when the engine
returns to idle, carburetor idle speed
should be adjusted (see "Adjusting
Engine Idle" below).
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 procedure
described here, return the trimmer to
your Shindaiwa dealer for inspection.
ALWAYS make sure the cutting attach-
ment is properly installed and firmly tight-
ened 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
attachment holder. If a properly installed at-
tachment vibrates, replace the attachment
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.

Stopping the Engine

Idle the engine briefly before stopping
(about 2 minutes), then slide the ignition
switch to the "O" (Engine OFF) position.

1. Place the trimmer 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 28.
3. If a tachometer is available, the engine
idle speed should be final adjusted to
3,000 min .

4. Carburetor fuel mixture adjustments are
preset at factory and cannot be serviced
in the field.
Do not operate with broken or damaged
equipment.
NEVER allow the engine to run at high
speeds without a load. Doing so could
damage the engine.
NEVER operate a unit with worn or
damaged fasteners or attachment holders.
When transporting, make sure the engine
is not running and the blade is covered
with the blade cover.
