FLUSHING THE HYDRAULIC SYSTEM 2.7
For flushing water from the hydraulic system, perform
the following procedures:
1 Remove any attachment.
2 Make sure all cylinders are fully retracted.
3 Change the hydraulic fluid. (fig. C1034)
4 Change the hydraulic filter. (fig. C2354)
5 Disconnect the hydraulic lines from one set of cylin-
ders. (fig. C2356, C1336)
6 Start the engine and set to the lowest idle.
7 Have someone hold the open hydraulic lines into a
container. Stroke the foot pedals, or hand operated, con-
trols slowly. Continue to repeat this cycle until the oil
comes out clear. Repeat for opposite set of cylinders.
8 Attach a hose and couplings to the auxiliary circuit.
Engage the auxiliary hydraulics, forward and reverse,
until the oil flows clear.
9 Connect 1 hose each, on each cylinder, to the fixed
end of the cylinder barrel.
10 Move the foot pedal or control lever to extend the
cylinder rods. This will flush the oil from inside the cylin-
der barrels. Be prepared to contain the waste oil.
11 Stop the engine.
12 Connect the hydraulic hoses to the rod end of the
cylinder barrel.
13 Replenish the hydraulic oil as required.
14 Replace the hydraulic filter.
