diameter cutters when using auto-feed mode.
THE FEED RANGE SELECTOR
There is a 3-position range selector switch on the switch panel which
allows ideal feed rate for various sized cutters. Select the feed range
which corresponds to the cutter diameter being used.
POSITION
RANGE
1
1/2" to 3/4"
2
13/16" to 15/16"
3
1" to 1-3/16"
AUTO-FEED OPERATION
1.
Always begin drilling manually (with the handles pointing out) as described above in “OPERATION-
GENERAL”.
2.
Only after the cutter has begun cutting for a few seconds and has raised a chip should the auto feed be
engaged.
NOTE: Do not cut manually for more than 10 seconds before shifting into auto feed. If manual cutting
continues for more than 10 seconds, as soon as auto feed is engaged, rather than cutting, it will directly
stop.
3.
To engage auto-feed, push any of the lever handles in. The gears may not always line up perfectly. If the
handle will not push in, simply raise the feed upward slightly and the lever will engage.
4.
As a precaution, always keep one hand near to the motor shut off switch in order to shut off quickly in
the event of any problem.
5.
Once the hole is drilled, the machine will continue to feed for 3 seconds (to fully finish hole) and then
will automatically shut off.
NOTE: This machine is equipped with safety override systems which will automatically engage: If the
load exceeds maximum for 2 seconds or more, the motor and feed will stop and stay in that position.
Only the magnet will stay on. This will alert the operator of an overload problem. If this happens
repeatedly, stop operation and find the cause of the excessive load. It could be a bad cutter or other
problem.
WARNING: WHENEVER THE MACHINE STOPS DUE TO OVERLOAD IN THIS WAY, RAISE THE CUTTER CLEAR
OF THE WORKPIECE BEFORE RESTARTING
NOTE: When drilling very deep holes with long reach cutters, there is considerable build up of chips.
This may interfere with operation and even cause the machine to stop from overload. In this situation,
we recommend stopping to clear the chips after the first 25mm (1 inch) or so, then continuing to finish
the cut.
