4. The trapeze arms (D)(Fig. 11) must hang freely. Re-adjust the
length of the link arms if necessary.
5. Tighten the jam nuts (C)(Fig. 10).
Boom Suspension Sensitivity
The factory setting of the boom suspension should normally suit most
conditions and will not require any adjustment. The suspension will
keep the boom parallel to the ground and compensate for uneven
ground.
However, special conditions or situations may require adjusting the
suspension to react faster or slower. Fine tuning can be done by
adjusting the inclination of the link arms.
When the RH and LH Link arm rods are parallel to each other (factory
setting), the boom suspension will react immediately, but dampened.
If the boom needs to follow the movements of the trailer more relaxed
(less dampened), the link arms may be adjusted inwards at the rear.
80', 90', 100', 120', 132' Suspension Sensitivity Adjustment
Remove the 4 bolts (E)(Fig. 12) holding the link
arm to the center section and move the rear of
the link arm to one of the available set of holes.
Note: There are 3 possible positions for
20
Link arms
attaching the rear of each link arm
to the center section. Make sure all
4 link arms are adjusted to the same
position (outside, middle or inside).
