➀
Examines the number of 1/4 in. thousands that have accumulated over the
life of the current drill bit. If the bit has drilled between
100,000–101,999 1/4 in. increments of paper, the ”change drill” light
illuminates steadily. When the value is between 102,000–103,999, the
”change drill” light flashes at a 1.28 second rate. When the value
reaches 105,000, the ”change drill” light flashes, and the ”change drill
now” light illuminates.
