Flush Hydraulic System
IMPORTANT: Flush the hydraulic system any time
there is a severe component failure or the system is
contaminated (oil appears milky or black or con-
tains metal particles).
IMPORTANT: Flush hydraulic system when chang-
Ing from petroleum base hydraulic fluid, such as
Mobil DTE 15M, to biodegradable fluid, such as Mo-
bil EAL 224H. Operate machine under normal oper-
ating conditions for at least four (4) hours before
draining.
1. Park machine on a level surface. Lower cutting units,
stop engine, engage parking brake, and remove key
from ignition switch.
2. Clean area around filter mounting area. Remove fil-
ter and drain reservoir into a suitable container. Drain
hydraulic system. Drain all hoses, tubes, and compo-
nents while the system is warm. Discard filter.
3. Inspect and clean reservoir (see Inspecting Reser-
voir Parts).
4. Make sure filter mounting surface is clean. Apply hy-
draulic oil to gasket on the new filter. Screw filter on until
gasket contacts mounting plate, then tighten filter half a
turn.
NOTE: Use biodegradable fluid, such as Mobil EAL
224H, for this step if you are changing to this type of fluid.
Use only hydraulic fluids specified in Traction Unit Oper-
ator’s Manual. Other fluids could cause system dam-
age.
5. Fill hydraulic reservoir.
6. Disconnect electrical connector to the fuel stop sole-
noid to prevent engine from starting.
7. Turn ignition key switch to start; engage starter for
ten (10) seconds to prime hydraulic pump. Repeat this
step again.
8. Attach electrical connector to the fuel stop solenoid.
9. Start engine and let it idle at low speed for a minimum
of two (2) minutes.
10.Increase engine speed to high idle for minimum of
one (1) minute under no load.
11. Raise and lower cutting units several times.

12.Shut off engine and check for hydraulic oil leaks.
Check oil level in hydraulic reservoir and add correct oil
if necessary.
13.Operate the machine for two (2) hours under normal
operating conditions.
14.Check condition of hydraulic oil. If the fluid shows any
signs of contamination, or if you are changing to biode-
gradable fluid, repeat steps 1 through 14 again.
15.Resume normal operation and follow recommended
maintenance intervals.
