ASSEMBLING & USING
STEP 1.
With the cutter blades correctly adjusted and holders perfectly
secure, slide the spindle through the hole in the protection cowl.
STEP 2.
Slide the compression spring on to the protruding spindle.
STEP 3.
Screw the wing nut on to the threaded end of the spind le in the
manner shown so that the assembly is secure.
Attach the assembly to a suitable variable speed hand drill
ensuring the spindle is perfectly secure. Select a speed in
accordance with the chart below.
Very carefully offer the complete assembly up to the workpiece,
switch ON and allow the pilot drill to begin its work.
The protection cowl will quickly come into contact with the
workpiece, ensure it is SQUARE.
Continue to push the spindle inwards, but DO NOT force it, allow
the cutters to come into contact with the work very gently. If the
cutters grab, the tool could be wrenched from your grasp. Take
care at this point.
NOTE:
Depth of cut may be set by adjusting the compression
spring wing nut, noting that it has a left hand thread.
Please note that it is possible to cut material, up to 34mm in
thickness. However, th is could cause damage to the perifery
of the hole in the material being cut, as the cutting blade
holders would create score marks on the surface. It is preferable
therefore to restrict cutting thickness to 30mm.
If it is possible to cut from both sides of the workpiece, then
the maximum thickness that may be cut is 60mm (or 68mm if
scoring of the work is not a problem).
In order to do this, first proceed to cut from one side as
described, then using a 8mm drill bit, drill the pilot hole through
the remaining thickness. Finally, very carefully cut from the
reverse side of the workpiece ensuring the pilot drill of the cutter,
neatly enters the pilot hole previously drilled.

SETUP
Using the Allen Key supplied, adjust the cutting blade holders
so that the cutting blades are at the desired diameter.
The inner edge of the holders should line up with the
appropriate graduation on the arm. See diagram A.
It is important to note the orientation of the cutting
blades, ensure they are correct. They should both be pointing
the same way as in the diagram B.
