Boom

Damping adjustment

When altered the guide rod setting in "Suspension performance
adjustment" then it is possible to adjust more accurately in the field. This
is done with the electrical damping control, which is situated at the
centre section of the boom.
When the throttle valve (A) is screwed all the way in, followed by three
reverse turns out (factory setting), the boom suspension will react
immediately, and the boom will move independently of the trailer or
tractor.
To obtain more damping: Throttle valve (A) must be screwed inward.
To obtain less damping: Throttle valve (A) must be screwed outward.

Boom folding speed adjustment

There are restrictors for adjusting of boom folding speed - one per each
boom wing. The restrictor are located near the big pendulum damping
cylinder.
Adjustment
• To decrease folding speed:
Loosen counternut (arrowed) and to adjust folding speed valve
(arrowed) must be screwed inward. Lock counternut again.
• To increase folding speed:
Loosen counternut (arrowed) and to adjust folding speed valve
(arrowed) must be screwed outwards. Lock counternut again.
ATTENTION! The system must not be pressurized during
adjustment.
