TRACTION MOTOR ELECTRICAL INPUT CHECK
1. Drive the machine on a level ground.
2. Turn the ignition key (10) to OFF position and activate the parking brake (17).
3. Open the hood (21) and fix it with the support rod (36).
4. Disconnect the battery electrical connector (38).

6. Disconnect the traction motor cables (A and B) from the deactivation key (43) connection (C) and from the
connection (D) on the electronic board.
7. Hook the machine at the front anchorages (34) by means of a proper lifting system and lift it 10 cm from the
ground. Then securely fix it in this position to allow to the rear wheels (24) to rotate freely without touching
the ground in the following tests.
8. Connect the traction motor to the machine battery, as described in the underlying diagram, inserting the 10
A fuse (H), for safety’s sake.
9. With an ammeter (F) check that the traction motor input is less than 8 A at 24V.
If the input is greater, carry out the motor brush check (see the procedure on the following pages). If
necessary, disassemble the traction motor (see the procedure on the following page), clean it and check its
moving parts.
If the above-mentioned procedures do not lead to a correct motor input it is necessary to replace the motor
(see the procedure on the following page).
10. Carry out steps from 1. to 8. in the reverse order.
