Wing tilt adjustment
The horizontal adjustment of the wings is carried out by the retracted tilt
cylinder. The boom must be straight and horizontal. If necessary, adjust
the wing as follows:
1.
Support the boom to relieve the load from the hydraulic cylinder.
2.
Loosen counter nut (A), which is positioned by the hinge ring on
the cylinder’s piston rod.
3.
With a wrench (on two flat spots on end of the ram), adjust the
cylinder ram inwards or outwards to get the desired wing level.
4.
Repeat the steps for the other side.
Slanting Indicator Adjustment (optional)
If the position of the pointer on the indicator does not correspond to the
actual boom position, the pointer (A) can be adjusted.
1.
Loosen the small bolt (B) sufficiently to allow the wire (C) to be
adjusted.
2.
Place the pointer (A) in correct position and fasten bolt (B) against
the wire (C) again.
Wear Bushing Replacement on Boom Lift
The wear bushes are inspected and renewed, before they are worn
through.
1.
Connect the trailer to a tractor and unfold the boom to working
position.
2.
Lift the boom centre frame with a lifting device and support it,
until the load is taken off the parallelogram arms.
3.
Remove the screws (A), and pull out the pins (B) at one of the
upper parallelogram arms and replace the wear bushes.
4.
Refit the arm.
5.
Repeat this on the other upper arm.
6.
The lower arms must be disconnected simultaneously
7.
Apply grease into all grease nipples.
8.
Remove the lifting gear again.
Change of Bulbs
1.
Switch off the light.
2.
Loosen the screws on the lamp and remove the cover or lens.
3.
Remove the bulb.
4.
Fit a new bulb, refit the cover and tighten the screws.

ATTENTION! If halogen bulbs are used, never touch the bulb with your fingers. Natural moisture in the skin will cause
the bulb to burn out, when the light is switched on. Always use a clean cloth or tissue when handling halogen bulbs.
