CIRCLE CUTTER INSTRUCTIONS
Step One: Assemble Circle Cutter
Unscrew pivot foot knob 1 and turn pivot foot
2 over so that center point 3 is down. For
holes 3/4"-9" (2cm-22cm), assemble with
center point 3 towards the tool. For holes 4"-
12" (10cm-30cm), assemble with center point
3 away from tool. Reattach the pivot foot
knob 1 and pivot foot 2 (Fig. H1).
Disconnect the plug
from the power source
before making any
adjustments or changing accessories.
Such preventive safety measures reduce the
risk of starting the tool accidentally.

Rotary Tool
If the Dremel chuck is installed, remove it
from the tool and replace it with the collet
and collet nut 4. Then remove nose cap 5
from your rotary tool and set nose cap aside.
The nose cap 5 must be reinstalled when this
attachment is not used (Fig. H2).
Do not use Dremel

attachment. Only use a collet and collet
nut.

Tool
The flutes on the bit are

handled with caution.
Insert the shank of the bit 6 into the collet so
that at least 1/8" of the smooth part of the
shank is visible above the collet, depress
shaft lock button and securely tighten collet
nut 4 (Fig. H3).
