OPERATION
1. Before making the connection to the electric control panel, check that the line voltage
corresponds to that shown on the motor plate. In case of three-phase motor, check also the row
or triangle connection of each phase.
2. The user must provide the electrical connection to the hoist using insulated conductors of
adequate cross-section and a multiple socket fitted upstream with a suitable switch with
differential magneto-thermal relay to protect form over current and indirect contacts. Also check
that the ground terminal in the socket is actually connected to the grounding system.
3. The cross-section of the power supply cable must be sized according to its length.
4. At the time of installation, check so that when the hook descends to the endpoint of its travel, at
least three turns of rope remain wound on the drum. The rope must never be unwound further
that this. The unwinding limit is shown on the rope by a red mark.
5. Do not under any circumstances use the hoist for lifting loads in a non-vertical direction.
6. In order to stop the hoist when running, it is usually enough to release the push-button on the
remote. Should an EMERGNECY STOP be necessary, press the red stop button to stop
operation, or disconnect from power source immediately.
7. During operating, constantly check that the rope winds onto the drum correctly.
8. It is strictly forbidden to cause the load to fall in an uncontrolled manner.
9. At intervals of no more than 15 days, check:
a). All the nuts and bolts on the hoist and the support are tight
b). The support is perfectly horizontal; if not, re-adjust
c). The brake suspending the load works effectively. If necessary re-adjust as follows: remove
the motor casing by loosening the 4 self-tapping screws on the fan cover; adjust the air gap by
unlocking the hexagonal socket head screw “A” and turning the nut “B”; the distance “C” must
be between 0.4 and 0.6mm. While the motor is running, the fan “D” must turn freely without
rubbing against the disc. Check that the brake works correctly, then replace the casing and fix in
place with the screw.
