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.
1.Place the trimmer on the ground, then start the engine, and then allow it to idle
2.If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw
3.If a tachometer is available, the engine idle speed should be final adjusted to 2,750 (±250) RPM
4.Carburetor fuel mixture adjustments are preset at factory and cannot be serviced in the field.
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 ricochet. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS!
Use only authorized Shindaiwa parts and accessories with your Shindaiwa trimmer. Do not make modifications to your unit 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 at-
tachment vibrates, replace the attachment with a new one and
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, or attachments.
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 dam- aged fasteners or attachment holders.
Using a Hand-Held Edger
Guidelines for Operating the Edger.

Remove debris and other obstacles that could be thrown by the rotating blade.
Plan your work so the edger blade is always on your

CAUTION!
Low-speed edging can lead to prema- ture clutch failure.
Do not move the edger into the work so fast that the engine or blade bogs down.
Regular and frequent use of the edger will make a neater lawn, and a frequently trimmed edge will be easier to maintain.
