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). Replace the device (Fig. 7/L) every 2000
operating hours because it is not possible to clean
it.
Reduce the change intervals accordingly depending
on how contaminated the discharged medium is.
Changing: Remove the purging cover (Fig. 7/T) and
the gasket after undoing the screws (Fig. 7/s
3
). Un-
screw the oil separator element (Fig. 7/L) with a hex-
agonal wrench (size 10) and replace.
NOTICE
Ensure that the O ring is correctly seated on the new
oil separator element.
Re-assemble in reverse order. Before fi tting lightly oil
the O ring Fig. 7/L

) on the new oil removing device
and tighten it to 15 Nm.
