Shoulder Strap
NOTE:
Using a shoulder strap with a brush-cutter
allows you to maintain proper control of
the unit and reduces fatigue during ex-
tended operation.

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.
NOTE:
Although a shoulder strap is not required
for use with a trimmer head, a shoulder
strap can increase operator comfort dur-
ing extended periods of operation.
WARNING!
Always wear a shoulder strap when op-
erating this unit with a blade. A shoul-
der strap is also recommened when
using trimmer line.
IMPORTANT!
Adjust the shoulder strap or harness 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 adjust-
ment devices are secure.
