Maintenance and repair
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 (5x) can become con-
taminated by dust particles after they have been
running for some time (power consumption and
pump temperature increase). Replace these compo-
nents (Fig. 7/L) every 2000 operating hours or when
the filter resistance is 0.7 bar (see pressure gauge
➝
Accessories, Checking 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).
