MAINTENANCE
Monthly maintenance is recommended. Lubrication is very important for 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 ram, linkages, saddle and pump mechanism with light oil. Grease wheels bearings and
axles.
2. Visually inspect for cracked welds, bent, loose, missing parts or hydraulic oil leaks.
3. If 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 ram oil level.
6. Check ram every 3 months for any sign of rust or corrosion. Clean as needed and wipe with an oil
cloth.
Always store your jack in the fully lowered position. This will help to 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.
CHECK OIL LEVEL
1. Turn release valve counterclockwise to allow ram to fully retract. It may be necessay 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 type HL or HM
3. Replace fill plug.
4. Check jack operation
5. Purge air from system if required.
TROUBLE SHOOTING
System air purge:
1. Turn release valve counterclockwise one full turn to open.
2. Pump handle several full strokes.
3. Turn release valve clockwise to close valve.
