5. Remove the old filter (Figure 60) and wipe the
surface of the filter adapter gasket clean.
6. Apply a thin coat hydraulic fluid to the rubber gasket
on the replacement filter.
7. Install the replacement hydraulic filter onto the filter
adapter (Figure 60). Tighten it clockwise until the
rubber gasket contacts the filter adapter, then tighten
the filter an additional 3/4 turn.
8. Clean up any spilled fluid.
9. Start the engine and let it run for about two minutes
to purge air from the system.
10. Stop the engine and check for leaks.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed within
a few hours by a doctor familiar with this form
of injury or gangrene may result.
• Keep your body and hands away from pin
hole leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks, never use your hands.
11. Check the fluid level in the hydraulic tank (refer to
Checking the Hydraulic Fluid in Operation , page 19)
and add fluid to raise the level to mark on dipstick.
Do not over fill the tank.
12. Close the rear access cover.
Changing the Hydraulic Fluid
Service Interval: Every 400 hours/Yearly (whichever
comes first)
Change the hydraulic fluid after every 400 operating
hours or yearly.
1. Position the traction unit on a level surface.
2. Open the hood.
3. Install the cylinder lock, stop the engine, and remove
the key.
4. Allow the traction unit to cool completely.
5. Remove the hydraulic tank cap and dipstick
(Figure 61).
Note:
The filler cap is behind the front screen. If
you want to improve your access to it, remove the
screen.
