For checking of the hydraulic oil level proceed as follows:
1) Remove the hood on top of the pump unit by opening the 8
allen screws on the bottom end of the hood.
2) Remove the yellow filler screw on top of the oil reservoir.
3) Push the diaphragm downwards until oil is coming out of the
filler screw so as to make sure that no air remains in the tank
and lock the tank with the filler screw.
4) For checking the correct filling volume adjust the upper part of
the oil tank to a horizontal position. Measure the distance bet-
ween reservoir bottom and upper edge.
The correct distance would be 147 mm.
5) Should the distance be other than 147 mm, refill or drain hydraulic oil.
10.4 Changing hydraulic oil
For changing of the hydraulic oil proceed as follows:
1)
Remove the hood on top of the pump unit by opening the 8 allen screws on the bottom end
of the hood.
2) Remove the yellow filler screw on top of the oil reservoir
3) Put the pump upside down and drain the oil completely
4) Adjust the tank so that the distance between reservoir bottom and upper edge is 147 mm.
5) Fill in fresh hydraulic oil until oil is coming out of the filler screw so as to make sure that no
air remains in the tank..
6) Hold the tank in its position and lock the tank with the filler screw.
7) Connect the battery (see 8.2), couple the two hydraulic hoses with each other and open
the drain valve (see 8.3).
8) Switch the motor several times on and immediately off again before it reaches high speed.
9) Switch the motor on, close the drain valve and keep the motor running for a few seconds.
10) Open the dump valve, switch the motor off and uncouple the hoses.
11) Open the filler screw again and repeat the procedure as per para 5 and 6, if necessary.
12) Lock the tank with the filler screw and clean the tank surface with a suitable cloth.
13) Mount the hood again.
10.5 For LUKAS hydraulic devices, use mineral oil in accordance with
DIN 51 524 and others
Recommended viscosity range: 10 ... 200 mm²/s,
