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 extremely rapid jerks, damaging the
internal components. The following steps are designed to keep the jack maintained and operational.
1. Lubricate the ram, linkages, saddle and pump mechanism with light oil.
2. Visually inspect for cracked welds, bent, loose, missing parts or hydraulic oil leaks.
3. The product shall be inspected immediately if it is believed to have been subjected to abnormal load
or shock.
4. Any hydraulic jack found damaged in any way, found to be worn or operates abnormally, shall be
removed from service until repaired by an authorized customer service representative.
5. Clean all surfaces and maintain all labels and warnings.
6. Check and maintain the ram oil level.
7. Check the ram every three 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 the ram all the way down.
Always store your jack in fully lowered position. This will help protect critical areas from 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.
IMPORTANT!
If the jack does not maintain the pressure and sinks, stop working with it immediately. Make sure that the
jack is repaired, or scrapped.
Check oil level
1. Turn the release valve counterclockwise to allow the ram to fully retract. It may be necessary to
apply force on the saddle for lowering.
2. With the jack in the level position, remove the oil fill plug. Stand the jack in horizontal 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 the system as required.
TROUBLE SHOOTING
System air purge
1. Turn the release valve counterclockwise one full turn to open.
2. Pump handle eight full strokes.
3. Turn the release valve clockwise to close it.
4. Pump the handle until the ram reaches maximum height and continue to pump several times to
remove the trapped air in the ram.
5. Carefully and slowly open the oil fill plug to release the trapped air and then close it.
6. Turn the release valve counterclockwise one full turn and lower the ram to the lowest position. Use
force if necessary.
7. Turn the release valve clockwise to closed position and check for proper pump action. It may be
necessary to perform the above more than once to assure that the air is evacuated totally.
