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.
• Lubricate the ram, linkages, saddle and pump mechanism with light oil. Grease wheel bearings and axles.
• Visually inspect for cracked welds, bent, loose missing parts or hydraulic oil leaks.
• If jack is subjected to abnormal load or shock, remove from service and have it examined by a customer service
representative prior to use.
• Clean all surfaces and maintain all labels and warnings.
• Check and maintain the ram oil level.
• 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 oils as they can damage the seals.
Always purchase and use products labelled Hydraulic Jack Oil.
Check oil level
1. Turn release valve counterclockwise 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. 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.
System air purge
1. Turn the release valve counterclockwise one full turn to open.
2. Pump handle eight full strokes.
3. Turn release valve clockwise to close valve.
