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.

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.

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.

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