ASSEMBLY

Adjusting the harness and clearing
saw

Standard harness

Safety release

At the front is an easily accessible, quick release. Use this if
the engine catches fire or in any other emergency situation
that requires you to free yourself from the machine and
harness.

Spreading the load on your shoulders

A well-adjusted harness and machine makes work much
easier. Adjust the harness for the best working position.
Tension the side straps so that the weight is evenly distributed
across both shoulders.

Correct height

1

Forestry clearing

The machine should be supported in a harness when
forestry clearing so that the cutting equipment is angled
slightly forwards in relation to the ground. Adjust the
height using the strap on the harness for the support
hook.

2

Grass clearing

The machine should be supported in a harness when
grass clearing so that the cutting equipment is parallel to
the ground.

Triobalance harness

Safety release

Push down the red release lever to release the machine from
the harness.

!

WARNING! When using a clearing saw it
must always be hooked securely to the
harness. Otherwise you will be unable to
control the clearing saw safely and this can
result in injury to yourself or others. Never
use a harness with a defective quick release.
