11. Replace the desiccant breather when necessary (see
the Replacing Desiccant Breather
topic).
12. Replace the filter elements.
13. Fully close the drain valve (8).
14. Loosen the tube nut fitting (11) located on the suction
manifold.
15. Remove the vent cap (12) from the suction manifold.
16. Fill the tank manually through the plug opening (2a) or
by pumping oil through the power-fill coupling (2b) with a
portable pump. Use new hydraulic oil filtered through a
10-micron filter.
Do not fill the tank through the breather port. The
hydraulic system could be contaminated from
unfiltered oil.
Fill the hydraulic tank to the full cold level (87 to 90%)
while watching the hydraulic tank display on the
information screen (see Figure 2-2
). Use the proper
hydraulic oil (see Section 9).
Do not fill the tank to 100%. Oil will contaminate the
desiccant breather.
17. Watch the vent cap (11) and fitting (12). When oil
appears at either location, tighten the fitting.
18. Apply 0.2 to 0.3 bar (3 to 4.4 psi) air pressure to the air
valve (4a) or to the coupler (4b) on the hydraulic tank.
Observe the vent ports and tighten the vent caps when
clear oil starts flowing from the vent ports.
19. Disconnect the air supply.
20. Check the tank level and refill as required.
21. Start the engine and allow the hydraulic system to return
to the normal operating pressure and temperature.
Check for leaks and tighten parts as required.
22. Stop the engine, check the tank level, and refill the tank
as required.
NOTE: If the hydraulic system was extremely dirty (gum or
lacquer formation on parts indicated by erratic,
jerky, or sluggish operation), repeat the Changing
Oil procedure after 48 hours of operation.
Servicing Pumps
It is not necessary to drain the hydraulic tank when servicing
the hydraulic pumps. To service the pumps, close the shut-
off valve (7a, Figure 2-1
).
Open the valve prior to starting the engine after servicing the
pumps.
CAUTION
Avoid Damage to Pumps!
Open the hydraulic tank shut-off valve before starting the
engine. Failing to open the valve will result in damage to
the pumps.
