 Clean, nonflammable solvent
When
Every 1000 hours of service or yearly
Procedure
Follow the procedure below to clean the hydraulic tank breather (a).
1. Open the engine compartment.

Changing the Hydraulic Oil and Filter
Set all controls in neutral, stop the engine, and allow the engine and fluids to cool before
performing this procedure.
All oils eventually shear or thin out with use, reducing their lubricating ability. In addition,
heat, oxidation, and contamination may cause the formation of sludge, gum, or varnish in
the system. For these reasons, it is important to change the hydraulic oil at specified
intervals. See Maintenance Schedule.
1. Remove the filler cap/filter cartridge from top of the hydraulic tank.
2. Remove the drain plug on the drain hose and allow the hydraulic fluid to drain.
Note: In the interests of environmental protection, place plastic sheeting and a container
under the machine to collect the liquid which drains off. Dispose of this liquid properly.
3. Unscrew the return line filter and replace the filter cartridge.
4. Install the drain plug on the drain hose.
5. Fill the hydraulic tank through the filler port with clean hydraulic fluid.
