NOTICE
Always change the oil when the machine is at
operating temperature and in an atmospherically
ventilated area.
If it is not completely emptied the amount that can
be refilled is reduced.
The waste oil must be disposed of in compliance with
the local environmental protection regulations.
If you are going to use another oil type, empty the oil
removing device housing and oil cooler completely.
A minimum oil quantity can get out of the vent screw
due to pressure compensation. If larger quantities of
oil escape, wash the internal filter of the vent screw.
The oil level in the sight glasses (Fig. 4/I) must be
checked every month.
The machine must be switched off and vented to at-
mospheric pressure to top up the oil.With clean op-
erations the oil must be changed after every 20,000
operating hours.
The oil viscosity must comply with ISO VG 150 as
per DIN 51519.
Designation as per DIN 51502: CLP HC 150.
We recommend the following oil brand:
GEAR-
LUBE 150 or equivalent oils by other manufacturers
(also see oil recommendation plate (Fig. 4/M)).
