Stopping The Engine; Adjusting Engine Idle; Checking Unit Condition - Shindaiwa PB3410 POWERBROOM Owner's/Operator's Manual

Starting the Engine (continued)
When the Engine Starts...
■
After the engine starts, allow the engine
to warm up at idle 2 or 3 minutes before
operating the unit.
■
After the engine is warm, pick up the
unit and clip on the shoulder strap
if so equipped. Refer to the section
"Operating: Optional Accessories" for
more information.

Stopping the Engine

Idle the engine briefly before stopping
(about 2 minutes), then slide the ignition
switch to the "O" (Engine OFF) position.

Adjusting Engine Idle

The engine must return to idle speed when-
ever the throttle lever is released. Idle
speed is adjustable, and must be set low
enough to permit the engine clutch to dis-
engage the cutting attachment.
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.

Checking Unit Condition

NEVER operate the unit with the protective
devices (ignition switch, etc.) removed!
ALWAYS make sure the PowerBroom tool
is properly installed and firmly tightened
before operation.
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa Multipur-
pose Tool. Do not make modifications to
your machine without the written approval
of Shindaiwa.

■
Advancing the throttle makes the cutting
attachment turn faster; releasing the throt-
tle permits the attachment to stop turn-
ing. If the cutting attachment continues to
rotate when the engine returns to idle, car-
buretor idle speed should be adjusted (see
"Adjusting Engine Idle" below).
Idle Speed Adjustment
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.
3. If a tachometer is available, the engine idle
speed should be final adjusted to 3,000
(±300) rpm (min ).

4. Carburetor fuel mixture adjustments are
preset at factory and cannot be serviced
in the field.
NEVER use a cracked or warped Power-
Broom drum or axle: replace it with a ser-
viceable one.
ALWAYS stop the engine immediately and
check for damage if you strike a foreign
object or if the machine becomes tangled.
Do not operate with broken or damaged
equipment.
OFF
NEVER allow the engine to run at high
RPM without a load. Doing so could dam-
age the engine.
NEVER operate a machine with worn or
damaged fasteners or attachment holders.
