SETUP INSTRUCTIONS
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. Depress the upper handle lock in the upper handle while simultaneously inserting the end of the upper handle in the lower handle. Rotate
the upper handle back and forth until the handle lock seats in the hole in the lower handle lock hole.
2. Unscrew the handle bolt so that it will not interfere with the insertion of the handle in the handle socket. Insert the handle in the handle
socket and rotate the handle assembly back and forth until the release valve fits in the receiver in the bottom of the handle. Secure the
handle in the handle socket by tightening the handle bolt.
3. Sometimes air gets trapped in the hydraulic system during shipping and handling. If the pump feels spongy, or there is not a full
incremental pump stroke, or the jack will not raise to maximum height, follow these instructions in order to purge air from the system:
a) With the lift arm in its completely retracted position and the pump handle rotated all the way in a clockwise direction until it stops,
rotate the pump handle in a counterclockwise direction two full revolutions.
b) Proceed to pump the jack 15 full incremental pump strokes.
c) Rotate the pump handle clockwise until it stops and proceed to pump the handle until the lift arm reaches maximum height.
d) Repeat steps "A" through "C" until all air is purged from the system.
