6.0 MAINTENANCE

Maintenance operations are listed hereinafter. A lower running cost and a longer machine life
depend, among other things, on the constant execution of these operations.
CAUTION: The listed time schedule is given for information, and relates to standard
operating conditions. It is susceptible of changes based on the type of service, level of
environmental dusts, frequency of usage, etc...
In case of heavier conditions, maintenance operations shall be carried out more frequently.
When topping-up or changing oil, always use the same type of oil used before.
WARNING: The following operations should be carried out with unladen lift.

6.1 VOLTAGE WARNING LIGHT

1) Turn Emergency Switch/Disconnector (19, Fig. 1) to «ON».
2) Check that the voltage warning light (21, Fig. 1) is on.

6.1.1 CARRIAGE BRAKING MECHANICAL SAFETY LOCKS

1) Press the UP push-button (22, Fig. 1) to lift the carriages completely.
2)
Release the UP push-button (22, Fig. 1) and wait for the carriages AUTOMATIC BRAKING
phase end.
3)
Remove central casings (1, Fig. 20) placed in every column outer side, to have access to the
electromagnets (3, Figg. 22-23).
4)
Pull the two screws controlling the electromagnet wedges outward (1, Fig. 22 - 23). If the
screws are blocked, the safety devices (2, Fig. 17) are engaged.

6.1.2 SAFETY DEVICES CONTROLLING THE CARRIAGE MISALIGNMENT

Raise the carriages up to approx. 1 metre off the floor and proceed as follows:
P1 carriage check:
1)
Place a wooden block (6, Fig.18) under P1 carriage to interrupt its down travel.
2)
Press the «DOWN» push-button (23, Fig. 1). When P1 carriage stops on the block, P2 carriage
should stop immediately as well.
DANGER: If P2 carriage does not stop, check the safety limit switch FC2 (Fig. 15) fixed
to the end of the cylinder of P1 column. Proper operation of limit switch FC2 is critical to
ensuring safe operation of the lift. Make sure it is correctly positioned and is operating
prop-erly before operating the lift.
P2 carriage check:
1) Place a wooden block (6, Fig.18) under P2 carriage to interrupt its down travel.
2)
Press the «DOWN» push-button (23, Fig. 1). When P2 carriage stops on the block, P1 carriage
should stop immediately as well.
