TAPPING OPERATION
NOTE: It is recommended to always use cutting
oil on the tap to give longer tap life and better
results. The automatic coolant system only
works for annular cutters. Taps must be
lubricated manually.
1. Before tapping begins, there must be a proper
sized hole. Make sure that the hole is the
correct size for the tap.
2. With the magnet switch still off, maneuver the
tap and machine to ensure that the tap is
perfectly aligned with the hole. Actually insert
the nose of the tap into the hole slightly to
ensure perfect alignment, then switch on the
magnet.
3. If you are tapping a blind hole, please use the
Travel Limiter Stop and the tapping depth
meter see “THE PROPER USE OF THE TAPPING
DEPTH METER” and "SETTING THE TRAVEL
LIMITER STOP" above.
4. To begin tapping, start the machine by
turning on the motor switch and use the crank
to feed the tap to the work. When there is no
feed pressure from the crank, the spindle will
be in neutral and will not spin. When there is
forward feed pressure, the spindle will
automatically spin in the forward (right hand)
direction. Tap the hole, then simply back out
the crank to reverse the spindle and remove
the tap. When there is backward pressure from
the crank, the spindle will automatically spin
in the reverse (left hand) direction. (Note that
it is not possible to tap left-hand threads with
this machine).
CAUTION: Do not too much reverse pressure
when backing out the tap or the tap could pull
out of the chuck. This could lead to premature
wear of the chuck.
SETTING UP FOR TWIST DRILLING
CAUTION: Never use a cutting tool which is
larger than the maximum rated capacity of the
machine.
NOTE: It is recommended to always use cutting
oil on the twist drill to give longer drill life and
better results. The automatic coolant system
only works for annular cutters. Twist drills must
be lubricated manually
1. If it is not mounted, mount the chuck to the
Drill Chuck Arbor.
2. Push up on the Quick-Release Collar to mount
the Drill Chuck Arbor to the machine. Double
check to ensure that the arbor is locked in
place.
3. Insert the drill bit into the chuck and tighten
with the chuck key.
