10.14  Changing the cooling oil

The machine must be isolated from the compressed air network and completely vented before

undertaking any work on the pressure system.
Drain the oil completely from the oil separator tank and oil cooler. Always change the oil filter

and oil separator cartridge when changing the oil.

Compressed air helps to expel the oil. This compressed air can be taken either from the compressor

itself or from an external source.

An external source of compressed air is necessary in the following cases:
■ The machine is not operational.
■ The machine is to be restarted after a long period of standstill.

Material Cooling oil

Cooling oil receptacle
The maintenance hose with hose coupling and shut-off valve is stowed beneath the oil separator tank.

WARNING

There is risk of burns from hot components and oil.
➤ Wear long-sleeved clothing and gloves.
