Adjusting the balance
Adjusting the shoulder harness
This product is designed to fit a wide variety of body sizes, but may not be adjustable for extremely tall persons. Do
not use the unit if your feet can reach the cutting attachment when the unit is attached to the harness.
A person's size can affect the balancing adjustment. Also the balancing procedure may not work with some units on some
persons. If the shoulder harness does not fit you or cannot be adjusted well, please ask your dealer for assistance.

of blade flying off during operation. Discard cracked blades
no matter how small the crack.

angle transmission while forcing retainer spring to the left
side.

Insert locking tool further into blade retainer fixing slot (C) to
fix output shaft.

ciently.
