Adjusting Engine Idle

Idle Adjusting

Screw

Figure 28

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 unit to your Shindaiwa dealer for inspection.

1.Place the unit 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 26.

3.If a tachometer is available, the engine idle speed should be final adjusted to 2,750 (±250) RPM (min-1).

4.Carburetor fuel mixture adjustments are preset at factory on units with emission control systems and cannot be serviced in the field.

Checking Unit Condition

NEVER operate the unit with the cut- ting attachment shield or other protective devices (harness, ignition switch, blade retention clip, 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, brushcutter, or lawn edger. Do not make modifications to this unit without the writ- ten 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 attachment: If a properly installed attach- ment 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 equip- ment.

NEVER allow the engine to run at high RPM without a load. Doing so could dam- age the engine.

NEVER operate a unit with worn or dam- aged fasteners or attachment holders.

NEVER cut with a dull blade. Doing so will increase the risk of blade thrust and may also cause equipment damage.

Shoulder Strap

Adjust the shoulder strap so the shoulder pad rests comfortably on the off-side shoulder and the cutting path of the cutting attachment is parallel to the ground. Make sure all hooks and adjustment devices are secure.

Grass Trimming

NOTE:

Although a shoulder strap accessory is not required for use with a grass trimmer, a shoulder strap can increase operator comfort during extended periods of operation. See Figure 29.

Using a Blade

WARNING!

Always wear a shoulder strap when op­ erating this unit with a blade. A shoul­ der strap is also recommended when using trimmer line.

NOTE:

Using a shoulder strap with a brush-cutter allows you to maintain proper control of the unit and reduces fatigue during extended operation.
