Starting the Engine (continued)
Starting A Flooded Engine
1. Disconnect the spark plug lead and use
the spark plug wrench to remove the
spark plug (turn counter clockwise to
remove).
2. Slide the ignition switch to the "O"
(STOP) position.
If the spark plug is fouled or
soaked with fuel, clean the plug as
necessary.

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
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.
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.

Checking Unit Condition

NEVER operate the unit with the cut-
ting attachment shield or other protec-
tive devices removed!
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer.
Do not make modifications to this unit with-
out written approval from Shindaiwa, Inc.
ALWAYS make sure the cutting attach-
ment is properly installed and firmly
tightened before operation.
NEVER use a cracked or warped
cutting attachment: replace it with a
ser viceable one.

ALWAYS make sure the cutting attach-
ment fits properly into the appropriate
attachment holder. If a properly installed
attachment vibrates, replace the attach-

and check for damage if you strike a
foreign object or if the unit becomes
tangled. Do not operate with broken or
damaged equipment.
NEVER allow the engine to run at high
RPM without a load. Doing so could dam-
age the engine.
