READY TO MAKE THE CUT
1.
Insert the annular cutter in to the machine arbor, lining up the flats on the cutter shank with the set
screws on the arbor. Secure the set screws making sure the screws are recessed in arbor body.
2.
Fill the coolant reservoir with a water-soluble coolant. Do not overfill! If drilling horizontally or inverted, use coolant
paste.
3.
Position the d2 drill on the work surface. Always use safety strap to prevent injury. Refer to the drawing
below.
Position 1 / Low Speed
Position 2 / High Speed
4.
If necessary, adjust the gearbox speed by turning the gear selector to the appropriate position.
Position one (1) is used for cutters 1
1/8” or larger, and turns at 180 RPM. Position two (2) is used for
cutters smaller than 1
1/8” and turns at 360 RPM. The arbor may need to be turned slightly to shift the gear
selector.
5.
Lower cutter to surface of material. Turn on coolant flow valve. Coolant flow will start when pilot pin is
depressed. Lifting pilot pin off work surface will stop coolant flow. Always remember to close valve when not
in use.
6.
Position chip guard toward work area before drilling.
7.
Place the drilling machine on the work piece, with pilot pin
over the center of the hole to be cut.
8.
Move the magnet
“ON” switch to the ON position. The switch
will illuminate to indicate DC power is going to the magnet.

. Depress motor
“ON” switch to start drill. If drill momentarily
turns on but will not continue to run, check to make certain
material is thick enough. Insufficient thickness can cause
magnet to lose hold, causing an operator hazard. If
necessary, clamp an additional section of steel to the
work-piece to increase magnetic adhesion. If material
d
2
thickness is less than 1/4
” (6mm), the magnetic field control system will not allow motor to start. This system
will turn OFF the motor after even minor movement of magnetic base. If holes must be made regularly in thin
(less than
3/8”) material, the magnetic field control system can be disabled permanently. (Consult Factory)
*Operational Note:
Models manufactured after 11-2006 have an electronic overload feature. If the drill
experiences over-current due to excessive cutter penetration speeds, the circuit will stop the drill motor. If
this should occur, simply reset the motor switch to the off position and then turn back on. Proceed with a
slower feed rate without forcing the cutter.
