the pump has reached its upper limit, the user will feel increased resistance at the crank
handle.
4.2 Retraction Cycle:
(Refer to Movotec
®
Crank Driven Schematic on page 6)
The crank is mechanically coupled to the pump leadscrew shaft. When the crank is
rotated in a counter-clockwise (CCW) direction, the leadscrew shaft rotates in the same
(CCW) direction. As the crank continues to rotate in a (CCW) direction, the threaded
pusherblock moves down the leadscrew in the direction of arrow “B”. As long as there is
sufficient load on the lift cylinder piston rods, the fluid in the lift cylinders flows back
through the hydraulic tubing and into the pressure elements. It is important to note that
the user will feel increased resistance at the crank handle when the pump has reached its
lower limit.
5.0 Unpacking Instructions
The system comes packaged in a cardboard carton. To unpack the system:
•
Check the carton label to confirm that you have received the correct system; open
the carton and remove packaging material.
•
Carefully remove the system from the carton, and verify all components are
present (reference chart below), and that the correct lift system was received.
Do not handle the lift cylinders and motorized pump by the hydraulic tubing. Incorrect
handling of hydraulic tubing could weaken the tubing material and system tubing
connections.
DAMAGE TO TUBING OR TUBING CONNECTIONS
COULD CAUSE FLUID LOSS AND UNCONTROLLED
DESCENT OF THE WORK-SURFACE.
