3. Hold the Set Exercise switch until the generator starts
(approximately 10 seconds) and then release. The
generator will start and run for approximately 12
minutes and then shutdown on it's own. The exerciser
will then be set to start and run at that time of that day
each week. If the unit does not start, go to Test 73.
Retest after performing Test 73. If the generator still will
not start, replace the circuit board. If the generator does
not start after depressing the Set Exercise switch, wait
one week and watch for exercise operation. If exercise
fails to operate, replace the circuit board.
