Diagnostic Display
Your truck has the Diagnostic Dis-
play. It should display "8888" on the
digital readout for about one second
after you turn the key switch to ON.
This indicates that the digital read-
out is OK. Then, either the battery
symbol or the wrench symbol light
should come on.
If the LED above the battery symbol
comes on, the digital readout shows
the percentage of usable charge
remaining on the battery. When the
remaining charge registers as 20%
or less, the Diagnostic Display
flashes on and off. When the display
registers 10%, the lift function be-
comes inoperable.

Symbol
If the LED above the wrench symbol comes on, a fault code appears on
the digital readout. The fault code may indicate an easily correctable
"operator fault" or it may indicate that you need to have the truck
serviced.
Fault codes -01 through -03, -06 and 08 are usually operator fault codes,
and can be corrected by the operator as explained in "Section 5,
Operating Procedures." If you see any other codes displayed, the truck
needs to be serviced.
Turn the key switch to the OFF position. The hourglass symbol light
should come on, and the hours registered on the truck should appear on
the digital readout for about four seconds. Write the hour meter reading
on the PM Report Form. Turn the key switch back to ON and apply the
parking brake.
