1. Place the trimmer on the ground, then
start the engine and 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.
3. If a tachometer is available, the engine
speed should be adjusted to 3,000 (±250)
RPM (min-1).
4. Carburetor fuel mixture adjustments
are preset at the factory and cannot be
serviced in the field.

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.
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

Checking Unit Condition
NEVER operate the unit with the cutting
attachment shield or other protective de-
vices (ignition switch, etc.) removed!
WARNING!
A cutting attachment shield or other
protective device is no guarantee of
protection against thrown objects and
ricochet. YOU MUST ALWAYS GUARD
AGAINST FLYING DEBRIS!
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trim-
mer. Do not make modifications to your
machine without the written approval of
Shindaiwa, Inc.
AlwAys make sure the cutting attach-
ment is properly installed and firmly tight-
ened before operation.
NEVER use a cracked or warped cutting at-
tachment: replace it with a serviceable one.
AlwAys make sure the cutting attach-
ment fits properly into the appropriate
attachment holder. If a properly installed
attachment vibrates, replace the attach-
ment 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 entangled.
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 the unit with worn or
damaged fasteners or cutting attachment
holders.
Edging with an Hand-held Edger
CAUTION!
Low-speed edging can lead to pre-
mature clutch failure.
 Do not move the edger into the work so
fast that the engine or blade bogs down.
 Do not pull the unit backward over the
ground with the engine running. Doing
so will tend to bury the blade.
Regular and frequent use of the edger
will make a neater lawn, and a frequently
trimmed edge will be easier to maintain.
Before edging, make sure the area is
soft enough so the blade does not bog
down. If necessary, water the area be-
fore edging.

Guidelines for Operating the Edger

WARNING!
Wear eye protection, long pants, and
boots when operating this unit!
Whenever you strike a hard object
with the blade, always stop the edger
and carefully inspect the blade for
damage. NEVER OPERATE THE
EDGER WITH A DAMAGED BLADE!
Figure 20
 Remove debris and other obstacles that
could be thrown by the rotating blade.
 Plan your work so the edger blade is
always on your right-hand side.
Begin each pass by positioning the unit
over the work, and with the engine run-
ning at about half-throttle. Slowly lower
the blade to the ground while applying full
throttle. See Figure 20.
