TROUBLESHOOTING
Symptom
Jack will not lift load
Jack bleeds off* after lift
*"bleeds off" means the load
slowly and unintentionally
lowers after lifting
While lowering, fluid leaks from
reservoir area
Jack saddle will not descend to
lowest 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
Possible Causes
• 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
Corrective Actions
• Ensure release valve is closed. Use the
provided handle to engage the release
valve. Turn the release valve clockwise
until firm resistance is felt.
• Consider higher capacity jack.
• Contact Customer Support.
• Drain fluid to proper level.
• Contact Customer Support.
• IF there is no longer contact between
the lifted load and the jack saddle, simply
remove the jack and follow the Owners
Manual Maintenance instructions for
bleeding air from system. However, IF
there is any loaded contact between the
saddle and the vehicle, STOP. Use
another jack to raise the load high
enough to re-install jack stands.
Remove the affected jack, then the
stands. Using the other jack, lower the
load by turning the release valve
counter-clockwise, but never more than
1/2 full turn, then follow the Owners
Manual Maintenance instructions for
bleeding air from system.
• Ensure proper fluid level.
• Carefully follow the Owners Manual
instructions for bleeding/venting the jack.
• Contact Customer Support.
• Ensure proper fluid level.
