Compound Miter Cutting - COMPANION 172.21199 Operator's Manual

To Bevel Cut cont.
6. Loosen the bevel lock knob and move the saw arm to the left to the desired bevel angle.
7. Bevel angles can be set from 0° to 45 °.
8. Align the indicator point with the desired angle.
g. Once the saw arm has been set at the desired angle, securely tighten the bevel lock knob.
10. Place workpiece flat on the miter table with one edge securely against the fence. If the board
is warped, place the convex side against the fence. If the concave edge of the board is against
the fence, the board could collapse on the blade at the end of the cut and jam the blade.
11. When cutting long pieces of lumber or molding, support the workpiece with a roller stand or other
support to bring the workpiece level with the saw table (see Fig. 28).
12. Align cutting line on the workpiece with the edge on the saw blade.
13. Hold the stock firmly with one hand and secure it against the fence. Use the hold-down clamp
or a C-clamp to secure the workpiece when possible.
WARNING:
To avoid serious personal injury, ALWAYS keep your hands outside the
"no hands zone"(red lines); at least 3 inches from blade. Also, NEVER perform any cutting
operation "freehand" (i.e. without holding workpiece against the fence); the blade could grab the
workpiece, causing it to slip and twist.
14. Before turning on the saw, perform a dry run of the cutting operation just to make sure that
no problems will occur when the cut is made.
15. Hold the saw handle firmly when squeezing the trigger switch. Allow several seconds for the
blade to reach maximum speed.
16. Slowly lower the blade into and through the workpiece.
17. Release the trigger switch and allow the saw blade to stop rotating BEFORE raising the
blade out of the workpiece. Wait until the electric brake stops the blade from turning BEFORE
removing the workpiece from the miter table.
COMPOUND MITER CUTTING
A compound miter cut is a cut made using a miter angle and a bevel angle at the same time.
This type of cut is used for moldings, picture frames, and boxes with sloping sides.
To make this type of cut the control arm on the miter table must be rotated to the correct angle and
the saw arm must be tilted to the correct bevel angle.
ALWAYS take special care when making compound miter setups due to the interaction of the
two angle settings.
Adjustments of miter and bevel settings are dependent on one another. Each time you adjust the
miter setting, you change the effect of the bevel setting. Also, each time you adjust the bevel setting,
you change the effect of the miter setting.
It may take several settings to obtain the desired cut. The first angle setting should be checked after
setting the second angle, since adjusting the second angle affects the first.
Once the two correct settings for a particular cut have been obtained, ALWAYS make a test cut in
scrap material BEFORE making a finish cut in good material.
