the gear case. (The small arrow on the tab will be pointing
downwards when it is shifted correctly).

SETTING UP FOR ANNULAR CUTTERS
1. If another arbor or accessory is in place, remove it from the
machine.
2. Insert the Coolant Feed Spring with the Seal facing
downwards into the shaft of the Annular Cutter Arbor.
3. Mount the Annular Cutter Arbor into the machine by pressing up on the Quick Release Collar and turning
the arbor until the collar snaps closed. Once it is closed, tighten the Knurled Lock Ring by turning
clockwise by hand.
4. Insert the proper sized pilot pin in the annular cutter. Using the L-hex key, loosen the 2 set screws to allow
the mounting of the annular cutter. Ensure that the flat of the cutter shank is facing the set screw and
then tighten.
5. If it is in tapping mode, shift the gearbox to drilling mode by swinging the gear selector tab out of the
detent slot then shifting upwards into drilling mode. Then pop the selector tab back into the detent. It
will usually be necessary to grab the arbor and push the spindle upwards while turning a little by hand to
get the selector to shift all the way up. Only grab the Arbor when turning the spindle, never the Quick-
Release Collar. Otherwise, it will be easy to accidentally release the arbor and it will fall out. Follow the
Twist drill & annular cutter” symbol on the gear case. (The small arrow on the tab will be pointing
downwards when it is shifted correctly).
