Flush Hydraulic System
IMPORTANT: Flush the hydraulic system any time
thereisa severe componentfailure or the systemis
contaminated. Contaminated oil appears milky or
black or contains metal particles.
1. Parkmachineonalevelsurface.Lowercuttingunits,
stop engine, engage parking brake and remove key
from ignition switch.
2. Drain hydraulic reservoir.
3. Clean area around the mounting areas of the hy-
draulic filters. Remove and discard hydraulic filters.
4. Drain entirehydraulicsystem. Drainallhoses,tubes
andcomponentswhilethesystemiswarm.Flushhoses
and tubes to remove any contamination.
IMPORTANT: If a failure occurred in the tractioncir-
cuit, traction circuit component disassembly and
thorough cleaning may be required to remove con-
taminates from the traction circuit. Because the
traction circuit is a closed loop, any contamination
will remain in the circuit and can cause additional
component damage unless it is removed.
5. Make surethemountingsurfacesofthehydraulic fil-
tersareclean.Applycleanhydraulicoiltogasketonnew
filters. Screw filters on until gasket contacts mounting
plate, then tighten filter 3/4 turn.
IMPORTANT: Use only hydraulic fluids specified in
Traction Unit Operator’s Manual. Other fluids could
cause system damage.
6. Fill hydraulic reservoir with new hydraulic oil.
7. Disconnectelectricalconnectortothefuelstopsole-
noid to prevent the engine from starting.
8. Make sure traction pedal is in neutral and the PTO
switch is OFF. Turn ignition key switch to start; engage
starter for ten (10) seconds to prime hydraulic pumps.
Repeat this step again.
9. Connect fuel stop solenoid to allow engine to start.
10.Startengineandletitidleatlowspeedforaminimum
of two (2) minutes.
11.Increase engine speed to high idle for minimum of
one (1) minute under no load.
12.Rotate steering wheel in both directions several
times. Raise and lower cutting units several times.
13.Shut off engine and check for hydraulic oil leaks.
Check oil level in hydraulic reservoir and add correct oil
if necessary.
