WARNING
The AC Reach Truck has a cooling fan installed
under the front left cover to regulate the mo-
tor controller temperatures. Some trucks have
a motor door fan installed as an added option
for higher temperatures or extreme duty cycle
operations. The cooling fans of the motor con-
trollers and motor compartment (if installed)
run continuously when power is on. Remove
power from the truck by turning the key switch
OFF and unplugging the battery before servic-
ing the truck or removing covers.
If power-on diagnostic checks are necessary re-
quiring servicing the truck with the covers re-
moved or the motor door open, the fans should
be unplugged first or suitable guards installed
over the fans to prevent possible injury from
the rotating blades of the fans. If diagnostic
checks require the lift motor or drive motor to
be used, the motor controller fan is required to
prevent the motor controllers from overheat-
ing and the front left cover for the fan must re-
main in place during operation of the truck.
CAUTION
Electrical components on this truck are po-

incorrectly. Make sure each electrical wire
connection is tagged and properly identified
before removal or installation. If the proper
location for connection is unclear, consult the
wiring diagram for the truck. Make sure test-
ing meters have adequate voltage and current
capacities to handle the output of the electri-
cal components they are used to check. Never
wire aftermarket components to this truck
without factory approval.
