OPERATION
5.1
Raise And Lower Lift
Prevent serious injury or death.
Before operating lift, all personnel interacting with lift must read, understand
and follow instructions and safety warnings in this manual.
Personnel must maintain a safe operating distance of at least 36” any time
lift is operated.
Adjusting safety relief valve may result in premature motor failure.
Do not adjust safety relief valve.
Raising loads exceeding rated capacity of lift may result in excessive wear and
damage to lift.
For lifts supplied with throw-over bridges, make sure bridges are in the stored
(raised) position prior to raising or lowering the lift, and when backing up trucks
for loading/unloading - to ensure that the bridges will clear all possible
obstructions and contact with a moving truck.
1. Verify all personnel are clear of lift.
2.
Press “UP” button to raise lift. Release button when lift reaches desired
position.
Do not operate lift on relief for more than a
few seconds. When on relief, valve will make a squealing
sound.
3. Press "DOWN" button to lower lift. Release button when lift reaches
desired position.
5.2
Raise And Lower Bridge (hydraulic)
If your lift has a hydraulically operated throw over bridge (TOB), it is equipped with UP/DOWN buttons and
a FLOAT switch. The FLOAT switch must be set to
“LOCK” for the UP/DOWN buttons to work. The
UP/DOWN operate just as the lift UP/DOWN. The FLOAT switch is to be used when the bridge is resting
on the truck bed. The “FLOAT” mode allows the bridge to float up or down with the truck.
This prevents damage to the equipment when loads are being moved across the bridge.
Note: Bridges that hang below 45 degrees are in violation of ANSI Standard MH29.1-2012 paragraph
4.12.2 which states “When a hinged bridge is in its fully lowered position and not resting on a truck bed or
landing, it should hang down at an angle not to exceed approximately 45 degrees from horizontal.…”
Autoquip
’s standard is to allow 20° of drop below horizontal.
