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.
