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 refi lled 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 com-
pletely.
The oil level must be checked at least once a day,
if necessary top the oil up to the upper edge of the
sight glass (Fig. 9/I) First oil change after 500 hours
of operation. Subsequent oil changes after 500 -
2000 hours of operation. Reduce the change inter-
vals accordingly depending on how contaminated
the discharged medium is.
When changing the oil the oil must be discharged
from the oil cooler (see oil discharge screw (Fig. 9/
K

Only lubricating oils complying with DIN51506 group
VC/VCL or a synthetic oil approved by Elmo Riet-
schle must be used. The viscosity of the oil must
comply with ISO-VG100 as per DIN51519.Elmo Ri-
etschle oil types: MULTI-LUBE 100 (mineral oil) and

mendation plate (Fig. 9/M)).
If the oil is subject to high temperatures (ambient or
intake temperatures over 30°C, insuffi cient cooling,
60 Hz operation etc.) the oil change interval may be
extended by using the recommended synthetic oil.
