Autoquip ABS AIR BAG LIFT - Manual (Page 20)

WARNING!
To avoid personal injury, NEVER go under the lift platform until the load is
removed and the scissors mechanism is securely blocked in the open position.
See the "Lift Blocking Instructions" section.
PROBLEM POSSIBLE CAUSE AND SOLUTION
Lift does not raise • The load may exceed the rating for the specific line
pressure.
• There may not be enough, or any, line pressure.
Check the supply pressure with a gauge and ensure
it provides the minimum pressures required.
• Make sure the air supply line is connected to the
correct port on the hand or foot control valve. It is
marked “Inlet”.
• It may be that an obstruction was introduced into the
system during installation. Check for obstructions at
the inlet of the control valve, in the connecting hose
to the lift, and at the restrictor in the bottom of the air
bag.
Lift drifts down slowly during
non-operation.
• Make sure all of the connections are tight and that
no leaks are occurring in the system.
Lift seems bouncy during
operation. • This is normal for large volume (air bag) air-powered
systems due to the compressible nature of air,
especially at raised elevations between fully
lowered and fully raised positions.
