1. Cautions
• Always disconnect the A.C. Cord from the outlet and and D.C. Cord from the
battery pack before servicing the machine. Except for making voltage and
current measurements.
• Before replacing or disconnecting any electrical componets, disconnect the
battery pack from the machine first. Failure to do so could cause a short
circuit.
• After any repair work test the machine for proper operation.
• When servicing the machine always observe the general safety and accident
prevention guidlines.
• Do not attempt to power up the controllers with battery chargers. Permanent
damage will occur to the controller.
36 volt chargers usually have an output in excess of 48 volts.
• Use only Minuteman approved battery chargers.
• Do not apply power directly to the motors without first disconnecting them
from the controller circuit.
