The protector must be installed to protect the operator from contact
with the cutting tool and thrown stones and debris.

protector extension is designed so that it will only mount onto the
protector in one direction. (Fig. 11)
NOTE: Remove tape adhered to the cord cutter, which cuts nylon
cord, on the protector extension at the first use.
To remove the protector extension, place a hex wrench or flat-blade
screwdriver into the small notch provided on the locking nub. Press

When replacing an accessory with another, the weight balance
of the equipment may change. In such case, adjust the hanger
position and shoulder harness length as follows.
To change the hanger position, loosen the fixing screw on the

farther away from the hanger.
After adjusting the hanger position, tighten the screw with a wrench
or screwdriver (depending on the power unit) securely.
