to a rotating part of the tool may result in personal injury. Do not overreach. Keep a proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hardhat, or hearing protection must be used for appropriate conditions. - Page 5 Symbol Name Designation/Explanation Volt Voltage (potential) Amperes Current Hertz Frequency (cycles per second) Watt Power Kilograms Weight Minutes Time Seconds Time Diameter Size of drill bits No load speed Rotational speed, at no load Revolutions per minute Revolutions, strokes, surface speed per minute.

MOUNTING ANNULAR CUTTERS CAUTION: Never use a cutting tool that is larger than the maximum rated capacity of the machine. To insert an annular cutter, first insert the pilot pin into the cutter. Then slide the cutter into the arbor, align the proper flat with the locking screw(s) and tighten securely with the supplied hex wrench. -
Page 8: Swivel Base
NOTE: Always ensure that the cutting tool is sharp. A dull cutter typically will have finer and/or choppy shavings. WARNING: ALWAYS clear chips when there is too much build-up. Excessive chip build-up could result in a jammed cutter or other hazardous situation. WARNING: the slug ejects at end of cut and is very hot. -

MT2 ANNULAR CUTTER ADAPTOR This machine is equipped with a unique annular cutter adaptor system with built-in coolant directly to the gearbox. To install the annular cutter adaptor, first insert the taper end of the adaptor into the arbor of the machine as described above. -
Page 10: Cutting Speeds
NOTE: whenever possible, it is always preferable to lower the speed by changing the gear rather than lowering the motor speed. A slower motor speed will have less cooling and somewhat less torque so always try to keep the motor going as fast as possible. Only lower the motor speed if you have no other option. -

MT2 SHANK ACCESSORIES If it is desired to use any of various MT2 shank accessories, such as twist drills, countersinks, reamers, etc., it may or may not be necessary to remove the arbor support bracket. If removal is necessary, then follow the instructions below for replacement. -

TAPPING For tapping, the arbor support bracket must be removed. To Replace, see the instructions above under: "ARBOR SUPPORT BRACKET REPLACEMENT". If using the optional two jaw universal tapping chuck, simply mount the unit in the spindle, insert the tap's square into the chuck and tighten firmly. (If using an outside sourced MT2 tapping chuck &... - Page 13 THE ARBOR SHAFT Keep the arbor shaft free of dirt and lightly grease as needed. If the arbor support bearing is noisy, it may be dirty or have a chip lodged in it. Remove the arbor shaft to clean and re-grease the arbor support bearing. THE GIBS (DOVETAIL SLIDES) The gibs require adjustment if too loose.
- Page 14 MAGNET TROUBLESHOOTING Full magnet performance is absolutely essential for magnetic drill operation. If the magnet works, but does not hold well, it is likely that one of the coils has failed. If the magnet does not work at all, it is likely to be a failed rectifier. (It is highly unlikely that both magnet coils would fail at the same time) NOTE: A faulty magnet coil can also damage the rectifier, so whenever there is a magnet problem, BOTH the magnet coils and rectifier must be checked.
