Before any electrical service is performed on 48 volt mod-
el vehicles, the Run-Tow/Maintenance switch must be
placed in the ‘Tow/Maintenance’ position.
If a power wire (battery, motor or controller) is discon-
nected for any reason on the 48 volt model vehicle, the
Run-Tow/Maintenance switch must be left in the ‘Tow/
Maintenance’ position for at least 30 seconds after the
circuit is restored.
To prevent electrical shock, the BL- wire must
be removed before discharging the controller
by shorting the B+ and B- terminals of the con-
troller with a large screwdriver. Be sure to hold
screwdriver by the insulated portion.
Using an insulated wrench, remove the BL- wire from
