4. Check the oil fi ll hole and, if necessary, top off the oil fi ll hole with hydraulic oil.
5. Replace the oil plug and close the release valve.
6. Test the equipment several times for proper operation before attempting to lift a load.
If, after bleeding, the equipment still does not appear to be working properly, do not use the
equipment until it has been repaired by a qualifi ed service technician.
Lifting and lowering
1. Locate the hole on the boom with a weight limit higher than
the weight you will be lifting.
For example: locate the 500kg holes on the boom for a load
that is under 500kg. (See fi gure k)
2. Adjust the boom extension so the hole farthest from the
hook-end aligns with the chosen hole on the boom.
Secure into place by inserting the boom bolt through
all aligned holes and securing in place with the washer
and nut (see fi gure l).
Warning!
Keep clear of the object that is being lifted by the
crane. Be aware of the possibility of a load slipping off
the hook and chain.
An item that falls from the crane can cause serious
injury.
3. Move the crane so that the hook and chain are
directly above the item to be lifted.
4. Securely attach the hook and chain to the item.
5. To raise the boom, turn the ram's release valve fully clockwise (right). Insert the handle into the
ram and pump (up and down) repeatedly until the item has been lifted to the desired height.
WARNING!
Fully tighten the release valve or else the ram may lower or may not be able to reach the full
height.
To lower the crane, slowly turn the ram's release valve counterclockwise (left).
