Adjusting Engine Idle

Operating Techniques

ENGLISH

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.

Operate the PowerBroom at or near full throttle with its sweeper fins resting on the work surface.

IMPORTANT!

It is both tiring and unnecessary to lift or hold the fins from the work surface during sweeping.

When sweeping narrow areas such as sidewalks, the PowerBroom can be used to throw material directly ahead of the operator. Clearing wider areas may require sweeping at an angle to create windrows to one side of the path being cleared.

Windrows of lighter materials often can be combined into one main row or pile for eventual pickup, while heavy or bulky material may need to be collected row-by-row. See Figure 22.

Sweeping Windrows

To pull debris from corners, reverse sweeper drum rotation by turning the powerhead over (throttle facing “up”). See Figures 23 and 24.

WARNING!

Reversing the PowerBroom will cause debris to be thrown back toward the operator. When reversing the PowerBroom, use lower throttle settings and be aware that thrown debris may also affect your footing!

DIRECTION OF

ROTATION

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 21.

3.If a tachometer is available, the engine idle speed should be final adjusted to 3,200 (±300) rpm (min-1).

NOTE:

Carburetor fuel mixture adjustments are preset at factory and cannot be serviced in the field.
