Autoquip CMD DOCK LIFT - Manual (Page 16)

16
1. Scissors lifts have maximum lifting capacity ratings (See the “Specifications”
section). The safety relief valve has been factory set to open at a point slightly
above the rated load and allows the oil to bypass into the reservoir. The safety
relief valve should not be adjusted for any reason as it could cause the motor
or pump 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 furnished with
constant-pressure pushbutton 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
operators’ hand 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 from the switch deactivates the “DOWN” circuit. The oil stops
flowing from the cylinders and the downward movement will stop
.
CAUTION!
Do not operate the power unit on relief for more than a few seconds. When on
relief, the valve will make a squealing sound.
PORTABILITY
The portability set is provided on the CMD as a means of moving the lift from one
location to another without a load on the lift. The portability wheels are located on each
side of the lift where the lifting cylinder is mounted to the lift platform (See Figure 7).
Each lift is supplied with a Dolly-T-Handle that is also necessary for making the unit
portable.
1. Raise the lift approximately half way.
2. Flip the portability wheels on the platform over to a vertical hanging position.
