2. Be sure that the battery cable connections are tight and free of corrosion.
3. Be sure that the battery hold-down bars are secure.
4. Remove the battery vent caps.
5. Check the battery acid level. If needed, replenish with distilled water to the bottom of the battery
fill tube. Do not overfill.
6. Install the vent caps.
A-4 Test the Oscillate System
The oscillate system is designed so that all four tires maintain firm contact with the ground on unlevel
terrain, improving traction and machine stability.
Proper axle oscillation is essential to safe machine operation. If the axle oscillation system is not
operating correctly, the stability of the machine is compromised and it may tip over.
Test The Oscillate System (Stowed Position)
1. Drive the left steer tire up onto a 4 in (10 cm) high ramp.
• Result:
All four tires should maintain firm contact with the ground.
2. Drive the right steer tire up onto a 4 in (10 cm) high ramp.
• Result:
All four tires should maintain firm contact with the ground.
Note:
Verify that there are no fault codes shown on ground control display.
Test The Oscillate System (Elevated Position)
1. Press the lift function select button. Raise the platform approximately 8 ft (2.4 m) from the
ground.
2. Drive the left steer tire into a 4 in (10 cm) deep hole.
• Result:
All four tires should maintain firm contact with the ground.
3. Drive the right steer tire into a 4 in (10 cm) deep hole.
• Result:
All four tires should maintain firm contact with the ground.
Note:
Verify that there are no fault codes shown on ground control display.
A-5 Check the Engine Oil Level
• Tools will be required to perform this procedure.
Maintaining the proper engine oil level is essential to good engine performance and service life.
Operating the machine with an improper oil level can damage engine components.
