WARNING

Do not attempt to check and reset circuit breakers

while driving the tractor. Always pull safely to side

of road ﬁrst. If tractor cannot be safely operated due

to a circuit breaker that cannot be reset, do not

attempt to operate tractor. Failure to comply may

result in damage to equipment or possible injury or

death to personnel. Seek medical attention in the

event of an injury.

There are nine 20 amp circuit breakers on the access

panel. If an electrical component will not function or

ceases to function (for example, the heater fan stops

with FAN switch in HIGH position), the circuit

breaker may have tripped and should be checked and

reset. To reset any circuit breaker, open panel cover,

identify circuit breaker by its number or if button is

out, and depress the button. If button remains in after

depressing it and component becomes operational,

close panel cover. If circuit breaker trips again, an

overload or short in the circuit has taken place. If

tractor can be safely operated without the affected

electrical item, complete mission and notify Field

Maintenance. If tractor cannot be safely operated,

secure tractor and notify Field Maintenance.
