Autoquip DOUBLE PANTOGRAPH LIFT - Manual (Page 34)

34
WARNING !
Familiarize yourself with this operator’s 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 inplant 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 !
Personnel should always maintain a safe operating 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.
