(TESTING PROCEDURES)
Single Column Test
(Repeat these procedures on each Column in Single

Lifting Test
1. After setting the Operation Mode to SINGLE on the
control panel, raise the lift unloaded by pressing and
holding the “UP” button to check if the carriage rises
normally.
If the Carriage raises slowly or jerks, the Cylinder may
have to be bled to release any trapped air in the hydraulic
system. If not, go to Step 3.
2. Raise the carriage above about 5”\127mm and
loosen the Cylinder Bleed Screw on the top of the
Cylinder one full turn or until air or oil ows out. DO NOT
completely remove bleed screws. Retighten after trapped
air has escaped. (See Fig 9.1)
Safety and Lowering Test
3. With the Carriage above 21”/533mm press and hold
the “PARK” button that became available when the lift
passed the indicated height. The lift will lower onto the
nearest safety lock. Continue holding the “PARK” button
and then check that the Carriage is securely on the safety
lock before continuing.
NOTE: When the PCL-18B is not loaded with a vehicle
the SPEED should be set to Rabbit mode or a fault
condition may be detected.
4. Press and hold the “DOWN” button. The carriage will
start to move up to clear the safeties and then down to the
to the ground or until the “DOWN” button is released.
Emergency Button Test
5. Test the Emergency Stop Button by hitting the
Emergency Stop Button while the lift is rising or lowering.
The lift should immediately stop. To Reset, twist button
clockwise. The button will pop back out.
