Replacing Oil Filter - Peri VARIOKIT VBC Assembly Instructions Manual

A5 Maintenance
Filling with new hydraulic oil:
1. Fill tank with hydraulic oil.
– Fill tank only up to the top mark-
ing. Do not overfill!
– The hydraulic oil used must be free
of water and dirt.
– Pour in the hydraulic oil using a fil-
ter pump or clean filling sieve (sep-
arate filling sieve, filling funnel with
sieve insert, or using an ultra-fine
filter).
– Do not mix hydraulic oils of differ-
ent manufacturers and quality.
2. Close the filling opening with an end
cap.
3. Check oil level.
4. Check the tightness of the oil tank
(e.g. caps, pipe penetrations,
flanges).
5. Record the type of oil used and vol-
ume in the maintenance chart and
note down on the unit.
Recommended hydraulic oil:
HM10 – ISO 11158, art. no. 131270.
HVI22 – ISO 11158, art. no. 131274
HVI46 – ISO 11158, art. no. 057376

Replacing oil filter

Preparations
1. Completely retract all hydraulic cylin-
ders, lower all loads. Alternatively,
short circuit all hydraulic lines. See
"Venting the system" on page 27 .
2. Switch off the hydraulic unit and dis-
connect the mains plug.
3. Remove residual pressure by actuat-
ing the control valves.
4. Caution!
Hot surface, hot oil!
Allow system to cool down.
5. Prepare collection tray and cleaning
cloths/cleaning rags to deal with
overflowing oil.
6. Secure the system against being
switched on.

Assembly
1. Carefully clean the area around the
filter.
2. If necessary, unscrew the oil filter
from the filter head in the anti-clock-
wise direction by means of a strap
wrench. Collect and correctly dispose
of any leaking oil.
3. Remove the protective cover from
the new filter element and attach it
on the used filter element.
– Do not reuse the residual oil in the
used filter element, and correctly
dispose of it together with the
element.
4. Uniformly wet the sealing ring of the
new filter element with hydraulic oil.
5. Hand-tighten the filter element onto
the filter head – no tools required.
6. After the hydraulic system has be-
come operational again, check for
leaks as well as the oil level. Top up
as required.
Disposal
1. Mop up any excess hydraulic oil with
cleaning rags.
2. Correctly dispose of the used filter
element and oil-contaminated auxilia-
ry materials.
