PROBLEM

POSSIBLE CAUSE

SOLUTION

THE APPLIANCE 

DOES NOT SWITCH 

ON

The main switch is OFF (50D versions).

Make sure the main switch is in the work position, the 

LED inside it is ON, and the ON symbol is visible. If 

this is not the case, press the main switch.

The  main  switch  is  in  the  "0"  position  (traction 

versions).

Make sure that the main switch is at "I", if not turn the 

key a quarter turn to right.

Check there are no alarm messages on the control 

display when the appliance is switched on (traction  

versions).

Stop the machine and contact the technician at the 

service centre.

Make sure that the batteries are correctly connected to 

each other and that the battery connector is connected 

to the electrical system connector.

Insert the batteries into the machine (see the 

section 

CONNECTING THE BATTERIES TO THE 

MACHINE'S ELECTRICAL SYSTEM

”).

Check the charge level of the batteries.

If the battery charge level is critical, perform a 

complete charging cycle (read “

RECHARGING THE 

BATTERIES

” or “

RECHARGING THE BATTERIES 

(VERSIONS WITH BUILT-IN BATTERY CHARGER)

”).

Check to make sure that the appliance is not still in 

its battery charging phase (versions with battery 

charger).

Perform the procedure to disconnect the power cable 

from the battery charger.

THE BATTERIES 

DO NOT WORK 

CORRECTLY

The batteries are not connected correctly

Properly connect the cable bridge, the output voltage 

should be 24V.

Properly connect the battery cable connector to the 

connector of the general system cable.

The terminals of the batteries are oxidized.

Unplug all cables from the batteries, clean the 

battery terminals, apply a little grease and restore the 

electrical connections (read the battery user manual, 

the manual provided by the battery manufacturer).

THE BATTERY 

CHARGER DOES 

NOT WORK

The plug of the power cable is not correctly inserted in 

the socket in the battery charger incorporated into the 

machine (versions CB).

Check that the plug in the battery charger power cable 

is connected to the socket in the battery charger.

The power supply cable plug is not correctly inserted 

in the mains socket.

Check that the plug on the battery charger's power 

cable is connected to the mains socket. Try another 

socket if necessary.

The characteristics of the mains power supply do not 

correspond to those required by the battery charger.

Check that the characteristics in the battery charger 

plate are the same as those of the mains supply.

The LEDs of the battery charger blink repeatedly 

(battery charger versions).

Referring to the battery charger use and maintenance 

manual, check the meaning of the flashing signals that 

the battery charger emits dung the battery recharge 

stage.

The plug of the power cable is not correctly inserted in 

the socket in the battery charger incorporated into the 

machine (versions CB).

Check that the plug in the battery charger power cable 

is connected to the socket in the battery charger.

The battery charger is not connected to the mains.

Connect the battery charger to a powered electrical 

outlet.

The battery charger is not connected to the batteries.

Connect the battery charger to the batteries.

Check that the mains outlet is functioning properly, or that it is not a daytime socket.
