9.3 Gear oil exchange
The gears of the motor are filled with gear oil at delivery (ISO VG 220
Ord. no.: 85.0110.00). To change the transmission oil, there is a filler
screw (o) at the top of the gear housing. To access it, the housing cover
needs to be removed as explained in Ä Chapter 4.3 ‘Setting up’
on page 18.
The oil needs to be changed after about 5 years.
9.3.1 Carrying out a gear oil exchange
1. Have the PULVERISETTE 13 premium line run for about 15 minutes
so that the gear oil inside warms up and drains better.
2. Remove the mains plug.
DANGER!
Disconnect the mains plug from the mains and secure
the device against being unintentionally switched
back on.
3. Disassemble the hood. (See Ä Chapter 4.3 ‘Setting up’
on page 18).
