MAINTENANCE
NOTICE: Use premium quality hydraulic jack oil. Avoid mixing different types of fluid and NEVER use brake fluid, turbine oil,
transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the jack and the potential for sudden and
immediate loss of load.
Adding Oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug/screw.
2. Fill with oil even with the bottom of the oil filler hole. Reinstall the oil filler plug/screw.
Changing Oil
For best performance and longest life, replace the complete fluid supply at least once per year.
1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug/screw.
2. Lay the jack on its side and drain the fluid into a suitable container.
NOTICE: Dispose of hydraulic fluid in accordance with local environmental regulations.
3. Fill with oil even with the bottom of the oil filler hole. Reinstall the oil filler plug/screw.
Lubrication
A periodic coating of light lubricating oil to pivot points will help to ensure that pump piston linkages move freely. Do not apply
oil to saddle area.
Cleaning
Periodically check the pump piston and ram plunger/saddle for signs of rust or corrosion. Clean as needed and wipe with a clean,
oil soaked rag. Do not apply oil to saddle area.
Storage
Store the jack with pump piston, ram plunger/saddle fully lowered and release valve open, but never more than 1 turn. This will
help prevent rust and corrosion to those critical surfaces.
WARNING: The paint on this product contains lead, a chemical known in the State of California to cause cancer, birth
defects and other reproductive harm. Do not ingest paint chips and keep product away from children. Wash hands after
each use.

TROUBLESHOOTING
Symptom Possible Causes Corrective Action
Jack will not pressurize
• Release valve not tightly closed
• Load is too heavy
• Ensure release valve tightly closed
• Consider higher capacity jack
Jack bleeds off after lift
(load slowly and unintentionally
lowers)
• Hydraulic unit malfunction • Contact Service Center
While lowering, fluid leaks from
reservoir area.
Jack saddle will not descend to low-
est advertised height.
• Reservoir overfilled
• Ram plunger/cylinder deformed,
seized up in ram cylinder and/or
top nut, likely the result of off-center
loading
• Drain fluid to proper level
• Contact Service Center
Ram plunger will not remain lowered
after released from contact with load
(creeps back up)
• Air trapped in system • Perform Bleeding/Venting Trapped
Air procedure.
Poor lift performance
• Fluid level low
• Air trapped in system
• Hydraulic unit malfunction
• Ensure proper fluid level
• Perform Bleeding/Venting Trapped
Air procedure.
• Contact Service Center
Will not lift to full extension • Fluid level low • Ensure proper fluid level
