•
Loosen the tensioning clamp by opening the screw, then carefully remove the filter
housing. Clean the housing and check all parts for possible damage. Remove the
filter element by pulling it down. Check the O-ring and, if necessary, replace it.
•
The filter element features twistlocks (bayonet or quarter-turn fasteners). This
facilitates changing it. All that needs to be done is to turn the element by 90° in a
clockwise or counterclockwise direction.
•
Release the filter element and carefully unscrew it by hand.
When opening the tensioning clamp be careful as there may be
residual oil in the filter housing.
•
Wet the O-ring between the filter housing and middle part and the O-rings on the filter
element with clean operating fluid. Now the new filter element can be inserted and
pressed tightly onto the connection piece.
•
Check the O-ring of the contamination retainer seal for damage and, if necessary,
replace it.
•
Slip the filter housing over the element, making sure that it seals properly and secure
it with the quick-action fastener.
Tightening torque for the quick-action fastener: 5
Nm (max. 10 Nm).
•
(Make sure that the drain screw located on the underside of the filter housing has
been securely screwed back in.)
6.2.2 Changing the Cartridge/Spin-on Filter Elements (MA, MG)
•
Switch the unit off and relieve the filter of pressure by carefully opening the drain
screw (wrench size: 6 mm) on the bottom of the filter housing (do not unscrew the
drain screw completely). Release the filter element and carefully unscrew it by hand.
Watch out for exiting oil.
•
Make sure that no further oil from the tubing of the hydraulic system enters the filter
unit and that nobody can switch the unit on again during maintenance.
•
Replace all gaskets and seals with the new ones supplied, slightly wet the sealing
ring with oil, and
manually
screw the filter cartridge tight.
There may be up to 1 liter of oil left in the filter element.
