Only lubricating oils complying with DIN 51506
group VC/VCL or a synthetic oil approved by Elmo
Rietschle must be used. The viscosity of the oil must
comply with ISO-VG46 as per DIN51519.Elmo Ri-
etschle oil types: MULTI-LUBE 46 (mineral oil) and
SUPER-LUBE46 (synthetic oil) see also oil recom-
mendation plate (Fig. 4/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..
WARNING
Heavily contaminated air oil removing devices lead
to increased pump temperatures and in extreme
cases may cause the lubricating oil to ignite spon-
taneously
The oil separator element may be contaminated with
particles of dirt when it has been running for a long
time (power consumption and pump temperature
increase). We therefore recommend replacing the
device every 3,000 operating hours (Fig. 5/L) as it is
not possible to clean it.
Reduce the change intervals accordingly depending
on how contaminated the discharged medium is.
Changing: Undo the screw button (Fig. 5/g). Remove
the fi lter cover (Fig. 5/h). Unscrew the oil reservoir
cover (Fig. 5/T). Replace the oil separator element
Fig. 5/L). Re-use the O ring (Fig. 5/L

).
