Before you start
Installing nylon line cutting head
1. Be sure the blade retainer (A) remains on the output shaft
(B).
2. Align the locking hole in the blade retainer with a notch at the
edge of the angle transmission and insert the locking tool
(C).
3. Install the line head (D) onto the output shaft by turning it an-
ticlockwise until the head is tight against the blade retainer.
4. Remove the locking tool.
Adjusting the balance
Adjusting the shoulder harness
 The accompanying shoulder harness is suitable for people of
standard adult physique, who are 150 cm - 195 cm in height
and 60 cm - 140 cm in waist size.

Use a shoulder harness when provided or when recommend-
ed in this manual. Adjust both harness and the suspension
point (A) on the unit so the unit hangs with the cutting attach-
ment a few centimetres above ground level (B).
 The cutting attachment and shield should be level in all direc-
tions. Harness the unit on the right side as shown.
 Slide suspension point up and down the tube to find the right
balance. Rotate the clamp to level the cutting attachment and
shield. Lock in position. If the suspension point is a free-spin-
ning type, the unit may tend to roll over sideways, however,
you should still level the attachment and shield on the front-to-
rear axis.
 Balancing and levelling, as above, may require relocation of
the clamp and readjustment of the harness straps. Also, each
type of cutting attachment and shield mounted on the unit may
require balancing.
CAUTION
 Fix the output shaft securely using the locking tool in
order to prevent it from rotating when mounting the ny-
lon line head.
WARNING
 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.
IMPORTANT
 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.
