Removing And Replacing Hydraulic Fluid
For the service interval (See SERVICE SCHEDULE on
Page 61.)
The fluid must be replaced if it becomes contaminated or
after major repairs. If the fluid is replaced, the hydraulic
filter must be replaced.
Remove the reservoir fill cap (Item 2) [Figure 106]. Put a
suction hose into the fill tube to remove the hydraulic
fluid.
Replace the hydraulic filter (Item 1) [Figure 106].
Add the correct fluid to the reservoir until the fluid level is
at the correct level (Do not overfill). Install fill cap.
Start the engine and operate the hydraulic controls. Stop
the engine and check for leaks.
Check the fluid level in the reservoir and add as needed.
Hydraulic fluid escaping under pressure can have
sufficient force to enter a person’s body by
penetrating the skin. This can cause serious injury
and possible death if proper medical treatment by a
physician familiar with this injury is not received
immediately.
