Maintenance mode allows you to test individual
circuits of switches and inputs while the lift
truck is stationary or under normal operation.

bad, you can verify the switch circuit input to
the
manager.
Enter the maintenance mode. See "Enter"
below. There are two methods for entering
Maintenance Mode, using the
pedal or
using the horn button. After you enter
maintenance mode, follow the instructions in
"General Testing."

1. Turn the key switch ON. The horn beeps
three (3) times after self-diagnostics is
complete.
2. Within 10 seconds after the three (3) horn
beeps, step on and off the
pedal
3-6 times. The horn will start clicking
when the truck is in maintenance mode.

lift, etc.
When the switch turns on or off, or
an
analog input crosses a threshold, the
truck determines whether the circuit is
good or bad.
If the
circuit is
good,
the horn clicks and
the heartbeat LEDs on the
manager and carriage manager, and the
steer indicator LEDs on the operator
display blink during the operator request.
If the
circuit is
bad,
the horn does not
click and the LEDs do not blink during the
operator request.
