Autoquip VERTICAL RAM LIFTS - DUAL RAM - Manual (Page 26)

Familiarize yourself with this operator’s manual before operating the equipment!!!
The remote self-contained power unit consists of an electric motor directly coupled to a
pump with a suction filter, check valve, relief valve, and solenoid down valve mounted to
a reservoir.
1. Ram 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 typically furnished with constant pressure pushbutton controls.
Actuating the "UP" button will cause oil to enter the ram(s) and the lift will rise.
3. When the desired height or upward travel of the platform is attained, removing
pressure from the button deactivates the “UP” circuit. The oil stops flowing and the
upward
movement will stop.
4. Activate the "DOWN" button to lower the lift. Opening the down control valve allows
the oil in the ram(s) 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 button deactivates the “DOWN” circuit. The oil stops
flowing from the ram(s) and the downward movement will stop.
CAUTION!
Do not continue to activate the "UP" button if the lift is not raising or if it
has reached the fully raised position. To do so may result in permanent
damage to the lift.
