BEFORE USE
• Read the operator's manual completely
and familiarize yourself thoroughly with the
product, its components and recognize the

reaches its maximum height.

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.

• Engage release valve with notched end
of jack handle. Open the release valve
b y t u r n i n g t h e j a c k h a n d l e
