Section 6 - Maintenance
Annual Checklist
The following maintenance should be done every year (annual) or 1,000 hours of operation.
D-1 Replace the Hydraulic Tank Return Filter Element
• Tools will be required to perform this procedure.
• New parts will be required to perform this procedure.
• A cold engine is required before performing this procedure.
Replacement of the hydraulic tank return filter is essential for good machine performance and service
life. A dirty or clogged filter may cause the machine to perform poorly and continued use may cause
component damage. Extremely dirty conditions may require that the filter be replaced more often.
Bodily injury hazard. Beware of hot oil. Contact with hot oil may cause
severe burns.
1.
Remove the filter with an oil filter wrench. Clean the area where the hydraulic oil filter meets the
filter head.
Bodily injury hazard. Spraying hydraulic oil can penetrate and burn skin.
Loosen hydraulic connections very slowly to allow the oil pressure to
dissipate gradually. Do not allow oil to squirt or spray.
Note:
The hydraulic filter is mounted on the hydraulic tank.
2.
Apply a thin layer of fresh oil to the new oil filter gasket.
3.
Install the new filter and tighten it securely by hand.
4. Use a permanent ink marker to write the date and number of hours from the hour meter on the
filter
5. Clean up any oil that may have spilled during the replacement procedure.
6. Turn the ground red Emergency Stop button clockwise to the on position. Pull out the platform
red Emergency Stop button to the on position. Start the engine.
7. Raise the platform approximately 3 ft (1 m).
8.
Inspect the filter and related components to be sure that there are no leaks.
