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

MAINTENANCE
Important
: Use only good grade 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. We recommend Mobil DTE13M or equivalent.
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.
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.
Lubrication
A periodic coating of light lubricating oil to pivot points will help to ensure that pump piston linkages move freely.
Note:
Never apply oil to saddle.
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.
Note:
Dispose of hydraulic fluid in accordance with local regulations.
3. Fill with oil even with the bottom of the oil filler hole. Reinstall the oil filler plug/screw.
