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

adjustment devices are secure.

brushcutter allows you to main-

tain proper control of the unit and

reduces fatigue during extended

operation.

hook stays at your right hand side.
Adjust the length of the shoulder

Using a shoulder strap when operat-

ing this unit with a blade allows you

to maintain proper control of the unit
