NOTE:

With the LUKAS hand and foot pump, a little idle stroke may occur when the 

unit is first used in the high pressure range.

However, this idle stroke independently disappears 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).

Locking pin

ATTENTION!

 

The hydraulic 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 the operation 

of the hydraulic 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!

7.  Commissioning

  7.2  Retracting the handle

You can pull out the handle by applying pressure to both sides of the thrust piece and 

simultaneously pulling in the direction of the handle end until the thrust piece re-engages.

  7.3  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.
