Corrective Action

closed. Use the provided handle
to engage release valve. Turn
release valve clockwise until
firm resistance is felt.
• Use higher capacity jack.
• Discontinue use, contact
Customer Support.
• Drain fluid to proper level.
• Contact Customer Support.
• If jack saddle is not in contact
with lifted load, remove jack
and follow instructions on
page 4 for bleeding air from

contact between saddle and
raised vehicle, STOP, use
another jack to raise vehicle
high enough to re-install jack
stands. Remove affected
jack, then jack stands. Using
a functioning jack, lower load,
then follow instructions on
page 4 for bleeding air from
system.
