DRIVE SYSTEM MOTOR ELECTRICAL INPUT CHECK

WARNING!
This procedure must be performed by qualified personnel only and with the help of an assistant.
1. Drive the machine on a level floor.
2. Apply proper wedges to rear wheels, so that the machine cannot move when the front wheel is lifted.
3. Slightly lift the front part of the machine and apply to the frame brackets two proper wooden shims high enough to keep the
front wheel lifted for about 3/4 in (20 mm) from the floor.
WARNING!
Pay attention to the rotation of the driving wheel when performing the following steps.
4. Use a jumper wire to disable the driver's seat microswitch (SW1).
5. Apply the amperometric pliers on the positive cable (red) of the battery wiring harness.
6. Turn the ignition key (58) to "I".
7. Drive the machine at the maximum forward speed by pressing the pedal (4) and check that the electrical input is 5 - 7 A at 24
V. Release the pedal (4). Turn the ignition key (58) to "0" and remove the amperometric pliers.
If the electrical input is higher, perform the following procedures to detect and correct the abnormal input:
• Check if there is dust or debris preventing the wheel rotation.
• If necessary, check if the electromagnetic brake slows down the wheel when the drive system motor is operating
[remove the electromagnetic brake and repeat the electrical input check (see the procedure in the electromagnetic brake
disassembly/assembly paragraph)].
• If necessary, check the motor carbon brushes (see the procedure in the following paragraph).
• If necessary, disassemble the motor (see the procedure in the drive system motor disassembly/assembly paragraph), and
check the condition of all its components.
If the above-mentioned procedures do not lead to a correct electrical input, the motor must be replaced (see the procedure in
the drive system motor disassembly/assembly paragraph).
