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.

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.

5. Check jack operation.
6. Purge air from system as required.
