For a shape that is not shown in the chart, use the following formula: 180°
divided by the number of sides equals the mitre (if the material is cut
vertically) or bevel angle (if the material is cut laying flat).
Cutting Compound Mitres (Fig. T)
A compound mitre is a cut made using a mitre angle and a bevel angle at
the same time. This is the type of cut used to make frames or boxes with
slanting sides like the one shown in Figure T.
WARNING: If the cutting angle varies from cut to cut, check that the
bevel lock knob and the mitre lock handle are securely locked. These
must be locked after making any changes in bevel or mitre.
The chart shown below will assist you in selecting the proper bevel and
mitre settings for common compound mitre cuts.
•
Select the desired angle A (Fig. T) of your project and locate that angle
on the appropriate arc in the chart.
•
From that point follow the chart straight down to find the correct bevel
angle and straight across to find the correct mitre angle.
•
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 26° exterior angles (Angle A, Fig. T),
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. K, U)
To complete straight 90° cuts, position the wood against the fence and hold
it in place as shown in Figure U. Turn on the saw, allow the blade to reach
full speed and lower the arm smoothly through the cut.
Cutting Base Moulding from 70 mm up to 150 mm High
Vertically Against the Fence (Fig. K, U)
nOTE: Use the slide lock lever
moulding measuring from 70 mm to 150 mm high vertically against
the fence.
Position material as shown in Figure U.
All cuts should be made with the back of the moulding against the fence
and with the bottom of the moulding against the table.

Cutting Crown Moulding (Fig. A1, V1, V2)
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 22.5°, 31.6° and
35.3° left and right for cutting crown moulding at the proper angle and
bevel stop pawls at 22.5° and 30° left and right. There is also a mark on
the bevel scale

at 33.9°. 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

Alternative Method for Cutting Crown Moulding
Cutting crown moulding using this method does not require a bevel cut.
Minute changes in the mitre angle can be made without affecting the
bevel angle. When corners other than 90° are encountered, the saw can be
quickly and easily adjusted for them.
Instructions for Cutting Crown Moulding Angled Between
the Fence and Base of the Saw for All Cuts (Fig. V2)
1. Angle the moulding so the bottom of the moulding (the part which
goes against the wall when installed) is against the fence
top of the moulding is resting on the saw table
2. The angled "flats" on the back of the moulding must rest squarely on
the fence and saw table.
