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 Unlocking the pump
Unlock (1.) the shipping lock of the pump by
sliding the locking pin in the direction of the
hand wheel until it comes against the stop.
To lock (2.) the pin, move it until it comes
against the stop in the other direction. To do
this, the lever must be in the home position
(at the tank).

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!
