Fig.13: Removing the high-pressure stage
1. Loosen screws(72013) between bellows(82300) and compressor casing(72000) and re-
move with washer(72014). The air suction branch(82000) with the bellows does not have
to be dismantled from the air line. To protect the bellows, the high-pressure stage must
not be lifted up together with the radial air suction branch and the bellows.
2. If present: Unplug the plug to the speed sensor(86505) and secure the rolled-up
cable(2m) to the high-pressure stage. This protects the plug from being crushed.
3. Treat the threads of the threaded rods(42191) and fixing screws(02) of the sup-
port(61300) with penetrating oil and allow it to take effect. Do not oil the pressure
screws of the clamping nut(42201).
4. Attach lifting gear to high-pressure stage with two swivel lifting eyes(03).
5. Loosen and remove the fixing screws(02) of the support(61300).
u Loosen the clamping nuts (42201) in accordance with the following section.
