NOTE:
With the LUKAS hand pump, a little idle stroke may occur when the unit is first
used in the high pressure range.
However, this idle stroke independently stops after a device is operated
2-3 times.
7.1 Locking the pump
ATTENTION!
The hand pump should be as close to horizontal as possible, because otherwise
the usable amount changes!
The oil fill plug must always be unscrewed one turn before starting operation of
the hand pump! This enables the aeration and bleeding of the hydraulic tank.
After the work is completed but before transport, the oil fill plug should be
retightened!
Commissioning 7.
7.2 Bleeding the pump
1. Open the discharge valve.
2. Open the oil fill screw plug on the tank container and check the oil fill level. The oil fill
level should come up to approximately 1-2 cm below the top edge of the oil reservoir.
3. In this state, work the pump handle several times.
