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 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, is 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.
8. When not in use, always leave the saddle and ram all the way down.
9. Always store your jack in the fully lowered position. This will help protect critical areas from
corrosion.
10. Do not use brake or transmission fluids or regular motor oil as they can damage the seals. Always
purchased and use products labeled Hydraulic Jack Oil.
CHECK OIL LEVEL
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 rubber oil fill
plug 1 (green).
3. Stand jack in vertical position with handle socket down.
The oil level should be 10 mm under the bottom of fill hole.
If not, top off. Do not overfill. Always fill with new, clean
hydraulic jack oil.
4. Replace fill plug and inspection plate.
5. Check jack operation.
6. Purge air from system as required.
ATTENTION: Never turn the red or yellow marked screws. Failure to consists an safety risk.
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 the handle until the lift arm reaches maximum height 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 lift arm 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.
