LIFT ADJUSTMENT AND TESTING PROCEDURE
(should be carried out in each detail by the installer)
WARNING: BEFORE PROCEEDING WITH THE TESTING OF THE LIFT, CAREFULLY CLEAN AND DRY ALL
THE CONNECTIONS, THE PISTONS AND THE OTHER PARTS OF THE LIFT HYDRAULIC SYSTEM.
• ADJUSTMENT OF THE CARRIAGE MECHANIC ALIGNMENT AND CORRECT ENGAGEMENT
OF THE MECHANICAL SAFETY LOCKS
1) Bring the carriages to the maximum height and align them hydraulically keeping the UP
push-button and the braking cut-off button pressed for a few seconds.
2)
Check the position of the carriages: the space between the first tooth of the carriage safety
lock and the movable wedge should be about 10 mm.
3)
Press UP for a few seconds, let the mechanic locks engaged and check that the wedges are
locked on the first tooth of the relevant carriages.
4)
Press DOWN push-button for a few seconds, then release it and check that the stop of the
two carriages on the safety devices is simultaneous; if it is not the case, adjust the P2 carriage
by blocking the checknut on the cylinder top and screw or unscrew the main nut to delay or
anticipate the carriage stop (every turn corresponds to 1.5 mm).
• TEST OF SAFETY DEVICE OPERATION (SEE INSTRUCTION MANUAL § 5.1.3)
1)
Check of the correct operation of the safety devices controlling carriage misalignment
2) Overhead safety shut-off system correct functioning check: stop of the lift raising by working
on the shut-off bar.
TESTING OF LIFT OPERATIONS
•
1) Load a vehicle on the lift and check:
2) correct hydraulic alignment at the maximum height.
3)
Correct lowering manoeuvre with safety lock release in the automatic mode (lift should go up
about 30-40mm before lowering)
4)
Correct engagement of the safety locks in the automatic mode.
5)
Correct operation of FCE: CUT-OFF OF THE SAFETY LOCK AUTOMATIC ENGAGEMENT
WITH MICROSWITCH ON.
HYDRAULIC SYSTEM TESTING
•
1) Lift the vehicle of about 50 cm using the UP push-button and the AUTOMATIC BRAKING
CUT-OFF PUSH-BUTTON (yellow) to prevent lift positioning on the mechanical safety locks.
2) Measure the carriages height at a specific point and write down the measured values.
After about 15 minutes, check for the tightness of the connections and of the other hydraulic
3)
parts.
4)
Measure the carriages height at the same point measured before and check with the starting
measured values: maximum shifting (lower) 1-2 mm.
WARNING!! IN CASE OF DOUBT WAIT WITHOUT MOVING THE LIFT AND CHECK AGAIN.
IN CASE OF DOUBT CONTACT THE A.G.M. SERVICE DEPARTMENT
