Chain, adjustment
1. The chain tension is controlled by two sets of plate springs
and adjusting nuts.
2. The chain play should be max 10-15 mm at retracted attach-
ment, when pressing with the thumb.
3. Adjust if needed with adjusting nuts. Lock with locknuts.
4. After 1–2 years or if the adjustment is fully utilized, remove a
link from the chain.
5. If the chain is slipping over the gear wheel, check the lubri-
cation, specially the fixed beam bottom surface, see section
Adjustment and lubrication of sliding plates.
Bleeding the damping cylinders
1. Set the boom in its lowest position.
2. Allow the engine to idle.
3. Carefully loosen the hose connection to one of the damping
cylinders until hydraulic fluid starts to leak out.
First air-free fluid will come from the connection and thereaf-
ter, fluid mixed with air. Re-tighten the connection once air-
free fluid again starts to flow.
4. Repeat this bleeding process for all four connections.
5. Run the boom up to its highest position and then down again.
