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.
The restrictor for adjusting of boom folding speed is located in the
main hydraulic block located behind the pendulum suspension
springs.
The adjusting screw is adjusted as follows
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.
There are restrictors for adjusting of boom folding speed - one per
each boom wing. The restrictor are located near the big pendulum
damping cylinder.
The adjusting screw is adjusted as follows
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.
