Cutting Compound Frames
A composite frame is a cut made using a square angle
and a chamfer angle at the same time. This type of cut
used to make frames or boxes with slanted sides.
NOTE:
if the cutting angle varies from cut to cut,
check that the chamfer firing button and the square
lock button are securely tightened. These buttons
must be pressed after any changes to the chamfer or
square have been made. The table shown will help to
select the appropriate settings for chamfer and square
for cutting common frame compounds.
Cutting of frames
In order to make a proper adjustment, the frames must
be cut very precisely. The two flat surfaces of a frame
have angles that, when joined, add exactly 90º. Most
frames have an upper back angle (the side that goes
against the flat part) of 52º and a lower back angle
(the side that goes against the wall) of 38º.
In this case, doing preliminary tests with patchwork of
frames is very important! Place the lower part (which
goes against the wall) against the guide of the miter
saw. Place the upper part (the one that goes against
the flat part) against the saw table and the frame
guide.
Instructions for cutting angular frames between the
guide and the saw table, for all types of cuts:
1. Place the frame so that the bottom of this (the
one that goes against the wall when affixed) is
against the guide and the upper part of the frame
against the saw table.
2. The miter plans at the rear of the frame must fit
directly on the guide and the saw table.
3. Check the cuts so that they are flat, thus avoiding
free spaces for their accuracy.

SPECIAL CUTS
NEVER MAKE A CUT IF THE MATERIAL IS NOT
SECURE ON THE TABLE AND GUIDE.
Aluminum Cutting
Use only specific discs for this cut. The instructions for
aluminum, such as those used to make frames, rails
etc., can be easily executed with the saw, using a disc
for cutting non-ferrous metals. Place the material so
that the thinnest part is exposed to the cut. When
cutting aluminum, use wax lubricant. Apply the wax
directly to the disc before cutting. Never apply wax
when the disc is in motion. The wax available in most
tool stores or in deposits of industrial suppliers offers
adequate lubrication and prevents the frames from
damaging the cutting disc. Make sure you have
properly fixed the part. Due to their size, shape and
surface finish, some parts may require
