closed. Use the provided handle
to engage the release valve.
Turn the release valve clockwise
until firm resistance is felt.
• Consider higher capacity jack.
Jack *bleeds off after lift
* ‘bleeds off’ means
the load slowly and
unintentionally lowers
after lifting
• Hydraulic unit
malfunction.

leaks from reservoir
area.

descend to lowest
advertised height
• Reservoir overfilled.

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.
