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 (V-VC 40/50/75 ¦ 3x,
V-VC 100/150 ¦ 4x) can become contaminated by
dust particles after they have been running for some
time (power consumption and pump temperature in-
crease). Replace these components (Fig. 7/L) every
2000 operating hours or when the filter resistance is
0.7 bar (see pressure gauge
¦ Accessories, Check-
ing with short term, atmospheric suction) because it
is not possible to clean them.
Reduce the change intervals accordingly depending
on how contaminated the discharged medium is.
Changing: Undo the air oil removers (Fig. 7/L) with a
ring spanner (spanner width 19 mm or 3/4”) rotating
counter clockwise. Insert new air oil removers with
the open lock symbol (see Fig. 8) with the arrow
‚
on the insert and fix turning clockwise (until it clicks
into place).
