• Loosen the fence clamping knob (91) and slide the upper part of the
side fence to the left as far as it will go.
• Loosen the bevel clamp knob (17) and set the bevel as desired.
• Tighten the bevel clamp knob fi rmly.
• Proceed as for a vertical straight cross-cut.
Compound mitre (fi g T1 - T4)
A compound mitre is a cut made using a mitre angle (fi g. T1) and a bevel
angle (fi g. T2) at the same time. This is the type of cut used to make
frames or boxes with slanting sides like the one shown in fi g. T3.
WARNING: If the cutting angle varies from cut to cut, check
that the bevel clamp knob and the mitre lock knob are securely
tightened. These knobs must be tightened 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. To use the chart,
select the desired angle "A" (fi g. T4) of your project and locate that
angle on the appropriate arc in the chart. From that point follow the
chart straight down to fi nd the correct bevel angle and straight across
to fi nd the correct mitre angle.
• Set your saw to the prescribed angles and make a few trial cuts.
• Practice fi tting the cut pieces together.
• Example: To make a 4 sided box with 25° exterior angles (angle "A")
(fi g. T4), use the upper right arc. Find 25° on the arc scale. Follow the
horizontal intersecting line to either side to get the mitre angle setting
on the saw (23°). Likewise follow the vertical intersecting line to the top
or bottom to get the bevel angle setting on the saw (40°). Always try
cuts on a few scrap pieces of wood to verify the settings on the saw.

Cutting base mouldings
The cutting of base moulding is performed at a 45° bevel angle.
• Always make a dry run without power before making any cuts.
• All cuts are made with the back of the moulding laying fl at on the saw.
Inside corner
- Left side
• Position the moulding with top of the moulding against the fence.
• Save the left side of the cut.
- Right side
• Position the moulding with the bottom of the moulding against the
fence.
• Save the left side of the cut.
SQUARE BOX
Outside corner
- Left side
• Position the moulding with the bottom of the moulding against the
fence.
• Save the right side of the cut.
- Right side
• Position the moulding with top of the moulding against the fence.
• Save the right side of the cut.
Cutting crown mouldings
The cutting of crown moulding is performed in a compound mitre. In
order to achieve extreme accuracy, your saw has pre-set angle positions
at 35.3° mitre and 30° bevel. These settings are for standard crown
mouldings with 45° angles at the top and 45° angles at the bottom.
• Make test cuts using scrap material before doing the fi nal cuts.
• All cuts are made in a left bevel and with the back of the moulding
against the base.
Inside corner
- Left side
• Top of the moulding against the fence.
• Mitre right.
• Save the left side of the cut.
- Right side
• Bottom of the moulding against the fence.
• Mitre left.
• Save the left side of the cut.
Outside corner
- Left side
• Bottom of the moulding against the fence.
• Mitre left.
• Save the right side of the cut.
- Right side
• Top of the moulding against the fence.
• Mitre right.
• Save the right side of the cut.
Sawing in the bench mode
• Always use the riving knife.
• Always ensure that the riving knife and blade guard are correctly
aligned.
• Always ensure that the mitre saw is set and locked in 0° mitre.
WARNING: Do not cut metal in this mode.
Ripping (fi g. U1 & U3)
• Set the bevel angle to 0°.
• Adjust the saw blade height.
• Set the parallel fence to the required distance.
• Hold the workpiece fl at on the table and against the fence. Keep the
workpiece approx. 25 mm away from the saw blade.
• Keep both hands away from the path of the saw blade.
• Switch the machine on and allow the saw blade to reach full speed.
• Slowly feed the workpiece underneath the upper blade guard, keeping
it fi rmly pressed against the fence. Allow the teeth to cut, and do not
force the workpiece through the saw blade. The saw blade speed
should be kept constant.
• Remember to use the push stick (23) when close to the blade.
