Changing the Hydraulic Fluid for the Lift and Slew System
1. Park the machine on a level surface, move the motion-control levers to the NEUTRAL-
LOCK position, engage the parking brake, raise the hopper, and install the cylinder lock.
2. Shut off the machine and remove the key. Allow the machine to cool completely.
3. Remove the filler cap from the reservoir tank
CAUTION
The hydraulic breather/filler cap is designed to pressurize the reservoir to 34 kPa (5
psi).
Loosen the cap slowly to avoid injury whenever adding fluid or working on the
hydraulic system. Use a wrench on the hex
directly under the cap.
4. Place a large drain pan under the fittings at the bottom of the reservoir tank.
5. Disconnect a hose fitting and allow the fluid to drain into the pan.
6. When finished, install and tighten the fitting. Note: Dispose of the used fluid at a certified
recycling center.
7. Fill the reservoir tank with approximately 5.9 L (200 fl oz) and install the filler cap.
8. Remove the cylinder lock.
9. Start the engine. Raise and lower the hopper 3 times to fill the cylinder and hoses with
fluid.
10. Raise the hopper and install the cylinder lock.
11. Shut off the engine.
12. Add 0.73 L (25 fl oz) of hydraulic fluid and install the filler cap.
Note: The fluid level should be at the Cold fill line. Do not fill past this line.
13. Remove the cylinder lock.
14. Start the engine. Raise and lower the hopper several times to remove air from the
system.
