Adjusting Engine Idle - Shindaiwa PowerBroom PB2500 Operator's Manual

Adjusting Engine Idle

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 2-3 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
-1
3,200 (±300) rpm (min ).
NOTE:
Carburetor fuel mixture adjustments are
preset at factory and cannot be serviced
in the field.

Operating Techniques
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
Figure 22
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!
