HYDRAULIC/HYDROSTATIC SYSTEM (Cont’d)
Replacing Hydraulic Fluid
See the Service Schedule Page 1–3 for the service
interval.
The fluid must also be replaced if it becomes
contaminated or after major repairs.
Remove the reservoir fill cap (Item 1) [A].
NOTE: Before installing the fill cap, make sure the
rubber gasket is installed on the fill cap
(Inset) [A].
Remove the screen (Item 1) [B] and thoroughly clean with
clean solvent.
Raise the operator cab. (See Page 1–8.)
Disconnect the hose from the hydrostatic motor case
drain filter (Item 1) [C].
NOTE: There is a 90 micron filter in each hydrostatic
motor case drain line.
Remove the two case drain filters (Item 1) [C] &[D] (one
for each hydrostatic motor) and clean thoroughly.
When all the fluid is removed from the reservoir, connect
and tighten the filters and case drain hoses.
Add the correct fluid to the reservoir until the fluid level is
between the marks on the dipstick. DO NOT fill above the
top mark on the dipstick.
Diesel fuel or hydraulic fluid under pressure
can penetrate skin or eyes causing serious
injury. Fluid leaks under pressure may not be
visible. Use a piece of cardboard or wood to
find leaks. Do not use your bare hand. Wear
safety goggles. If fluid enters skin or eyes, get
immediate medical attention.

Always clean up spilled fuel or oil. Keep heat,
flames, sparks or lighted tobacco away from
fuel and oil. Failure to use care around
combustibles can cause explosion or fire
which can result in injury or death.

Lower the operator cab. Start the engine and operate the
