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 piston, linkages, saddle and pump mechanism with light oil. Grease the wheel bearings and axles.
2. Visually inspect for cracked welds, bent, loose, missing parts or hydraulic oil leaks.
3. If the 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 piston oil level.
6. Check the piston 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 piston all the way down.
Always store the 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 the piston 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 the fill hole. If not, top off. Do not overfill. Always fill with new, clean hydraulic jack oil.
3. Reinstall the fill plug.
4. Check the jack's 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 the handle fully eight times.
3. Turn release valve clockwise to close valve.
4. Pump the handle until the piston reaches maximum height and continue to pump several times to remove trapped air in the piston.
5. Carefully and slowly pinch oil fill plug to release trapped air.
6. Turn release valve counter-clockwise one full turn and lower the piston 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 ensure air
is evacuated totally.

Causes and solutions
Release valve is not completely
closed (Turn handle clockwise).
Weight capacity has been
exceeded.
Air is in the hydraulics.
Purge air from system.
●
Low oil level. Add oil as required.
Oil reservoir is overfilled.
Drain excessive oil.
Lubricate moving parts.
Jack is jammed or there is a
foreign obstruction.
Power unit malfunctioning.
Replace the power unit.
