Autoquip PLTC DOCK LIFT - Manual (Page 38)

38
WARNING !
Familiarize yourself with this manual before operating this
equipment. Only trained and qualified personnel should
operate this equipment.
1.
Scissors lifts have maximum lifting capacity ratings (see “Specifications” section).
The safety relief valve has been factory set to open at a pressure slightly above
the rated load capacity and allows the oil to bypass into the reservoir to prevent
damage to the lift and its hydraulic power unit. The safety relief valve should
not be adjusted for any reason as it could cause the motor to prematurely
burn out. Applying loads exceeding the rated capacity of the lift may result in
excessive wear and damage to the lift.
2.
This type of lift is designed primarily for dock applications and is typically
furnished with constant pressure pushbutton (or foot switch) controls. Actuating
the "UP" button will cause oil to enter the cylinders and the lift will rise.
3.
When the desired height or upward travel of the platform is attained, removing
the operator’s hand or foot from the switch deactivates the “UP” circuit button.
The oil stops flowing and the upward
movement will stop.
4. To lower the lift, activate the "DOWN" button. Opening the down control valve
allows the oil in the cylinders to flow through the down valve at a controlled rate
and return oil to the reservoir.
5. When the desired height or downward travel of the platform is attained,
removing the operator’s hand or foot from the switch deactivates the “DOWN”
circuit. The oil stops flowing from the cylinders and the downward movement
will stop.
WARNING !
Non-operating personnel should always maintain a safe distance
of at least 36” any time the lift is operated up or down.
NOTICE !
Do not operate the power unit on relief for more than a few
seconds. When on relief, the valve will make an audible
squealing sound.
