TO REPLACE MACHINE CIRCUIT BREAKER
FOR SAFETY: Before Leaving Or Servicing

Machine; Stop On Level Surface, Set Parking

Brake, Turn Off Machine And Remove Key.

1. Remove the battery cables from the battery.

2. Go in the machine operators compartment

and locate the removable circuit breaker

plate.

3. Remove the six M6 screws holding the

removable circuit breaker panel to the

machine. Pull the panel back far enough to

allow access to the wires on the circuit

breakers.

4. Locate the circuit breaker that needs to be

replaced. Remove the wires leading to that

circuit breaker.

5. The round, metal lock ring, that is holding

the circuit breaker to the panel, must be

removed.

NOTE: A new lock ring is provided with the new

circuit breaker in case the old one is damaged

during the removal procedure.

6. Pull the old circuit breaker out of the hole

and discard it. Retain the clear rubber boot.

NOTE: Re--use the clear rubber boot on the new

circuit breaker.

7. Position the new circuit breaker in the panel.

NOTE: The circuit breaker is ”D” shaped and will

only go in the hole one way.

8. Install the lock ring on the new circuit

breaker. Push it down all the way to the

panel.

9. Reconnect the wires to the new circuit

breaker. See electrical schematic in this

section.

10. Reinstall the circuit breaker plate to the

machine. Tighten the six M6 screws to

8 -- 10 Nm (5 -- 6 ft lb).

11. Reconnect the battery cables and start the

machine, checking for proper circuit breaker

operation.
