Maintenance unit
It is important that an automatic maintenance unit, consisting of oiler, filter ,water separator and air pressure
reducer is installed in the main air supply - if not assembled by the manufacturer this must be assembled by
the customer.
It serves for the necessary preparation of the operation air so that the pneumatic motor can work trouble-
free. Installation must be as close as possible to the motor; - in no cases should the distance to the motor
exceed 10 m.
Should higher pressure occur in the supply net, it will be reduced to the operating pressure of 6 bar by the
pressure reducing valve. The oiler enriches the air with oil. Setting of oil addition: approx. 2 drops of oil must
be added per minute.
NOTICE!
HADEF does not assume any responsibility for damage caused by non-observance of the instructions.
CAUTION!
Should the unit be assembled at the customer, the maintenance unit is supplied without oil.
Before putting the unit into operation, the main air supply line must be cleaned and the oiler of the
maintenance unit must be filled with oil. Should this not be done the unit may be severely damaged.
CAUTION!
The maintenance units are not approved for use with synthetic oil.
They must not be connected to compressed air systems which are supplied by compressors with synthetic
lubricants.

Gear
NOTICE!
For transport, some gear types are fitted with a plug screw. Replace the plug screw by a ventilation screw
(attached) before putting the unit into operation.
