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 elements may be contaminated
with particles of dirt when the machine has been
running for a long time (power consumption and
pump temperature increase). Replace these com-
ponents (Fig. 10/L) every 2000 operating hours or
when the fi lter resistance is 0.7 bar (see pressure
gauge (Fig. 10/Y)
➝ Accessory, check with short
term atmospheric suction) because it is not possi-
ble to clean them.
Reduce the change intervals accordingly depending
on how contaminated the discharged medium is.
Changing: Unscrew the maintenance cover (Fig. 10/
W). Replace the oil separator elements (Fig. 10/L).
Re-assemble in reverse order. Before fi tting the O
ring lightly oil the new oil remover and tighten it to
15 Nm (wrench width 19 mm or
3
/

”).
