SELF--DIAGNOSTIC TEST
The machine is capable of running a
self-diagnostic test of its electrical system and
components.
1. Turn the machine power off.
2. Press and hold the squeegee switch while
turning the machine power on. Continue
holding the squeegee switch for five
seconds, then release the switch.
3. While the self--diagnostic test is running, the
battery discharge indicator on the far right
will flash. The machine systems will activate
as follows:
D
The brushes and squeegee raise.
D
The vacuum fan starts and the
squeegee lowers. The squeegee raises
and the vacuum fan shuts off.
D
The scrub head lowers and raises.
D
The brushes turn on and off.
D
The solution valve turns on and off.
D
The vacuum fan relay is momentarily
energized (the vacuum fan does not
turn on).
D
The brushes turn on and off.
4. If the electrical system passes the
self-diagnostic test, the indicator light above
the squeegee switch will blink (green).
If the self-diagnostic test finds an error in the
system, the recovery tank full indicator will
blink (red).
To determine which errors were found, hold
down the
rear squeegee switch
and record
which, if any, of the brush down pressure
indicators illuminate or blink. Repeat this
operation with the
scrub switch
. Be sure to
record which pressure indicators illuminate
or blink when each switch is held down.
Contact service personnel with the error
code data.
5. Turn off the self--diagnostic test by turning
off the machine power.
