FITTING THE CUTTER
N.B. Safety strap and guards have been omitted from the photo's for clarity.
Insertion of pilot pin
• The pilot pin is used to both center the cutter and
to eject the slug on completion of the cut. It has a
flat side to allow coolant to run down to reach the
center of the cut where the heat is greatest. Slide
the pin through the hole in the center of the cutter
shank.

To insert the cutter in the arbor, first loosen the grub
screws, using an M5 hexagonal wrench. Ensure the grub
screws are sufficiently loose enough to allow the shank of
the cutter to enter freely.

• Cutting oil ensures longer cutter life and enables
the slug to be ejected cleanly. A 500 ml bottle is
included with every machine.
• Oil will be automatically delivered to the cutter
when the cut commences.
• When cutting on vertical surfaces or upside down,
