Prime the charge pump as follows:
A.
Shut off the engine and remove the key.
B.
Loosen the 2 socket-head capscrews
(

C.
Lift the charge pump housing upward and
wait for a steady flow of fluid to flow out
from under the housing.
D.
Tighten the capscrews.
E.
Repeat this for both pumps.
Note:
The hydraulic reservoir can be
pressurized to up to 34.5 kPa (5 psi) to speed up
this process.
8.
If either drive wheel still does not rotate, stop
and repeat steps
and
on the respective
pump. If the wheels rotate slowly, the system
may prime after additional running.
9.
Check the hydraulic-fluid level.
10.
Allow the machine to run for several minutes
after the charge pumps are primed with the drive
system in the F
AST
position.
11.
Check the hydraulic-control linkage adjustment;
