hook receiver.

WARNING!

NEVER operate the unit without the cutting attachment

shield installed and tightly secured!

WARNING!

A cutting attachment shield or other protective device is

no guarantee of protection against ricochet. YOU MUST

ALWAYS GUARD AGAINST FLYING DEBRIS!

IMPORTANT!

Discard blades that are bent, warped,

cracked, broken or damaged in any way.Use

a sharp blade. A dull blade is more likely to

snag and thrust.

combination spark plug wrench/screwdriver, tighten the bolt rmly in a

counter-clockwise direction.

Remove the hex wrench.6.

The unit should now be completely assembled and ready for use with a

blade.

IMPORTANT!

Units with adjustable carburetors must be readjusted for blade use, otherwise

serious engine damage can occur.

WARNING!

A standard grass trimmer unit with loop handle should NEVER be operated with blade-type attachments. For blade use,

the trimmer must be tted with a bicycle-type handlebar or barrier bar that is located in front of the operator to reduce the

risk of the operator coming in contact with the cutting attachment. (Per ANSI B175.3). When using a blade, the unit must

be equipped with a harness or strap.

Shoulder Strap

NOTE:

Although a shoulder strap accessory is not required for use with a grass

trimmer, a shoulder strap can increase operator comfort during extended

periods of operation.

WARNING!

Always wear a shoulder strap when operating this unit with a blade. A

shoulder strap is also recommended when using trimmer line.

NOTE:

Using a shoulder strap with a brush-cutter allows you to maintain proper

control of the unit and reduces fatigue during extended operation.

Adjust the shoulder strap so the shoulder pad rests comfortably on the off-side

shoulder and the cutting path of the cutting attachment is parallel to the

ground.
