Flush Hydraulic System
IMPORTANT: Flush the hydraulic system any time
there is a severe component failure or the systemis
contaminated. Contaminated oil appears milky or
black or contains metal particles.
1. Parkmachineon alevelsurface. 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 entire hydraulicsystem. Drain all hoses, tubes
and componentswhile thesystem iswarm. Flushhoses
and tubes to remove any contamination.
IMPORTANT: If a failure occurred in the traction cir-
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 surethe mounting surfaces of the hydraulic fil-
tersareclean.Applycleanhydraulic oiltogasketonnew
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. Disconnectelectrical connector to the fuel stopsole-
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.Startengine andletitidle atlowspeedfor aminimum
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.
14.Operate the machine for two (2) hours under normal
operating conditions.
15.Checkconditionofhydraulicoil.Ifthefluidshowsany

16.Resume normal operationand follow recommended
maintenance intervals.
