7 Adjust the shoulder strap to distribute the load evenly
across your shoulders. Press downwards on the
suspension hook to load the harness.
8 Adjust the side belts to fit around the rib cage until the
breast plate is centred on the chest.
Adjust the height of the hanging ring as per the
instructions. (For forest clearing, the suspension should
hang approx. 10 cm below your hip bone.)
9 If you need to lower the suspension hook, for trimming
for example, move the suspension strap (A) to the
lower mounting point on the backplate. The front belt
that is attached to the breast plate can also be
adjusted if necessary.
10 The elastic strap (B) can be tightened to transfer more
load from the shoulder straps to the hip strap.
Correct balance
1 Forestry clearing
The machine is balanced by moving the suspension
ring on the machine forwards or backwards. On some
models the suspension ring is fixed, however, this will
then have a number of holes for the support hook. The
machine is correctly balanced when it freely hangs
horizontally from the support hook. In this way the risk
of hitting stones is reduced if you need to release the
handlebar.

ASSEMBLY

i.e. close to the ground.
