Manual Extensions
When working with manual extensions, please note:
The load limits indicated for manual extension must never be exceeded.
Great care should be taken if the slewing system is to be activated during work with manual extensions.
If the crane is fitted with manual extensions or other equipment, the lifting capacity of the crane must be reduced by the weight of this equipment.
Always check that lock bolts are fitted correctly with a pin.
Only pull out the manual extensions when the jib is as close to horizontal as possible.
If the jib is pointing downwards when the lock bolt is removed, the extensions will drop out at uncontrollable speed.
This may ruin the stop at the risk of resulting in personal injury.
The load must not be extended from the stop, i.e., the extension lock pins must always remain in place.
