Cutting Crown Moulding (fig. 1, 24A, 24B)
Your mitre saw is well suited to the task of cutting crown moulding. In
order to fit properly, crown moulding must be compound mitred with
extreme accuracy.
Your mitre saw has special pre-set mitre latch points at 31.62º left and
right for cutting crown moulding at the proper angle and bevel stop
pawls at 33.86º left and right. There is also a mark on the bevel scale
(K) at 33.9º. The chart below gives the proper settings for cutting crown
moulding.
NOTE: Pretesting with scrap material is extremely important!
INSTRUCTIONS FOR CUTTING CROWN MOULDING LAYING FLAT AND
USING THE COMPOUND FEATURES (FIG. 24A)
1. Moulding should lay flat with the broad back surface down on the
saw table.
2. Place the top of the moulding against the fence.
3. The settings below are for 45° sprung crown moulding.

• Set your saw to the prescribed angles and make a few trial cuts.
Practise fitting the cut pieces together.
Example: To make a 4-sided box with 26º exterior angles (Angle A,
fig. 22), use the upper right arc. Find 26° on the arc scale. Follow the
horizontal intersecting line to either side to get mitre angle setting on saw
(42°). Likewise, follow the vertical intersecting line to the top or bottom
to get the bevel angle setting on the saw (18°). Always try cuts on a few
scrap pieces of wood to verify the settings on the saw.
Cutting Base Moulding (Fig. 13, 23)
• Straight 90º cuts:
– Position the wood against the fence and hold it in place as shown in
figure 23. Turn on the saw, allow the blade to reach full speed and
lower the arm smoothly through the cut.
CUTTING BASE MOULDING FROM 76 mm UP TO 171 mm (3" UP TO
6.75") HIGH VERTICALLY AGAINST THE FENCE
NOTE:
Use the slide lock lever (A6), shown in Figure 13, when cutting
base moulding measuring from 76 mm to 171 mm (3" to 6.75") high
vertically against the fence.
Position material as shown in figure 23.
All cuts should be made with the back of the moulding against the fence
and with the bottom of the moulding against the table.
