Maintenance
Monthly maintenance is recommended. Lubrication is critical to jacks as they support heavy loads. Any restriction due to dirt, rust, etc., can cause either slow
movement or cause extremely rapid jerks, damaging the internal components. The following steps are designed to keep the jack well lubricated:
1. Lubricate the ram, linkages, saddle and pump mechanism with light oil. Grease wheel bearings and axles.
2. Visually inspect for cracked welds, bent, loose, missing parts or hydraulic oil leaks.
3. If jack is subjected to abnormal load or shock, remove from service and have it examined by a customer service representative prior to use.
4. Clean all surfaces and maintain all labels and warnings.
5. Check and maintain the ram oil level.
6. Check ram every 3 months for any sign of rust or corrosion. Clean as needed and wipe with an oil cloth.
When not in use, always leave the saddle and ram all the way down.
Always store your jack in the fully lowered position. This will help protect critical areas from excessive corrosion. Do not use brake or transmission fluids or
regular motor oil as they can damage the seals. Always purchase and use products labeled Hydraulic Jack Oil.
Oil level check
1. Turn release valve counter-clockwise to allow ram to fully retract. It may be necessary to apply force to the saddle for lowering.
2. With the jack in the level position, remove the oil fill plug. Stand jack in vertical position with handle socket down. The oil should be level with the bottom
of fill hole. If not, top off. Do not overfill. Always fill with new, clean hydraulic jack oil.
3. Replace fill plug.
4. Check jack operation.
5. Purge air from system as required.
Troubleshooting
System air purge
1. Turn release valve counter-clockwise one full turn to open.
2. Pump handle eight full strokes.
3. Turn release valve clockwise to close valve.
4, Pump handle until the ram reaches maximum heigh and continue to pump several times to remove trapped air in the ram.
5. Carefully and slowly pinch oil fill plug to release trapped air.
6. Turn release valve counter-clockwise one full turn and lower ram to the lowest position. Use force if necessary.
7. Turn release valve clockwise to closed position and check for proper pump action. It may be necessary to perform the above more than once to assume air
is evacuated totally.
