BEFORE USE
•Read the operator's manual completely
and familiarize yourself thoroughly with the
product, its components and recognize the
hazards associated with its use.
•Occasionally during shipment and/or
handling air can get trapped in the system,
which can interfere with the jacks lifting
performance.
• It is recommended to cycle the jack a few
times without applying load:
• Engage release valve with notched end
of jack handle. Close release valve by
turning the jack handle clockwise until

• Insert jack handle into handle sleeve.
Pump the handle until the jack saddle
reaches its maximum height.
• Engage release valve with notched end
of jack handle. Open release valve by
turning jack handle counterclockwise, but
no more than 1/2 full turn. Allow the saddle
to reach its lowest position.
• Repeat the above procedure a few times.
•To release air from the hydraulic system:
• Engage release valve with notched end
of jack handle. Open the release valve
by turning the jack handle
counterclockwise, but never by more than
