Wear Bushing Replacement on Boom Lift
Inspect and renew the wear bushes 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.
Wear Bushing Renewal on Steering
If too much play is found in the steering, the wear bushes must be replaced.
This should be done at your local HARDI dealer.
Suspension Rubber Dampers
If the rubber dampers loose their efficiency, they should be replaced.
1. Connect the sprayer to a tractor to prevent overbalancing.
2. Lift the rear end of the sprayer with e.g. a crane. Use lifting points as described in "Sprayer setup".
3. Loosen the nut below the suspension rubber dampers.
4. Remove the suspension rubber dampers and replace with new ones.
5. Tighten the nut below the suspension rubber dampers.
6. Lower the rear of the sprayer again.

Change of Light 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.
