9.1.1 Carrying out a gear oil exchange

1.

Have the PULVERISETTE 13 classic line run for approx. 15 minutes

so that the gear oil inside warms up and drains better.

2.

Remove the coupling cover by unscrewing the fastening screws

with a no. 4 hexagon socket screw key on both sides.

3.

Take off the coupling cover.

4.

Remove the motor fastening screw under the oil drain screw with

a no. 6 hexagon socket screw key.

5.

Hold a 25 ml laboratory scoop under the oil drain screw and

unscrew the screw with a no. 5 hexagon socket screw key. Hold

the oil drain screw with the hexagon socket screw key. The oil

flows into the laboratory scoop.

6.

If the laboratory scoop is full, screw in the oil drain screw and

empty the scoop into a container that is at least 250 ml.

7.

Repeat steps 5 and 6 until all the gear oil has run out of the gears.

8.

Wipe up any oil that spills with a paper towel and clean the con-

tact surface of the oil drain screw.

9.

Screw the oil drain screw and sealing washer back in firmly. Reas-

semble the motor fastening screw and the coupling cover.
