Page 9
WARNING!
The lift is equipped with a tamperproof pressure regulator. The regulator has been factory
preset and no attempt should be made to alter the setting. Resetting of the regulator or
replacement with a component not supplied by Presto-ECOA Lifts will void warranty and
could result in serious bodily injury.
D. TESTING THE LIFT WITH NO LOAD
1. Before testing the lift, clear the area of any loose material. Be sure the lift has no obstruction
above it or on any side. Using the controls provided, briefly oper- ate the lift (5-10 seconds). If the lift
begins to rise and functions properly, continue to the full upright position.
CAUTION!
If the lift does not rise immediately, or there is any operational problem, stop it immediately.
Refer to the troubleshooting section and correct the problem before continuing.
2. After raising the lift completely, lower the lift completely. It should lower slowly and smoothly. If satisfied
with the lift's operation, raise and lower the lift and stop at different levels in order to familiarize yourself
with the lift’s operation.
C. PNEUMATICS
AX/AXR/AXS/AT and AL Scissor Lifts are designed
for normal factory environments. Consult the
distributor for unusual applications. If your lift is
equipped with a turntable positioning lock, refer to
Section 6B.
CAUTION!
All pneumatic connections should
be performed by qualified authorized
service personnel.
1. The lift requires a minimum of 80 PSI, 15 CFM,
and clean dry air to function correctly.
2. Be certain that supply line is turned off and
residual air has been purged from the line.
3. The lift is shipped with the control line attached
to the control valve (B) and detached from the lift
base. Route the control line safely to the base and
make the connection (C).
4. Connect the supply line to the open port of the
control valve (A).
