Corrective Action
• Ensure release valve tightly
closed. Use the provided handle
to engage the release valve.
Turn the release valve clockwise
until firm resistance is felt.
• Consider higher capacity jack.
• Discontinue use, 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 instructions on page 4
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 instructions on page 4 for
bleeding air from system.
• Ensure proper fluid level.
• With ram fully retracted, follow
the instructions for bleeding
air on page 4.
• Contact Customer Support.
• Ensure proper fluid level.
