OPERATIONS
IMPORTANT
To help perform the safest and most precise
mitre saw cut, make the cut and then release the
power switch. Hold the power head down and
keep your hands in place until the blade stops
rotating. Then raise the power head and remove
workpiece from work table.
BEVEL CUTTING (WITH SLIDE ACTION) (Fig. 13)
A bevel cut is made by cutting across the grain of the
■
workpiece with the blade angled to mitre table.
A bevel cut is made with the mitre table set at zero
degree position and the blade set at an angle
between 0° and 45° to the table.
Pull out the lock pin (14) and lift the saw head to its
■
full height (Fig. 1).
Loosen the mitre lock knob (9).
■
Press and hold mitre lock handle (5).
■
Turn the table until the mitre pointer aligns with zero
■
on the mitre scale (10).
Release the mitre lock handle (5). Tighten the knob
■
(9) to hold the table in position.
Loosen the bevel lock lever (16) and turn the saw
■
head by hand to the left to the desired bevel angle.
Bevel angles can be set from 0° to 45° (Fig.1).
Align the bevel pointer with the desired angle.
■
Tighten the bevel lever (16) securely (Fig. 1).
■
Switch on the laser.
■
Lay the workpiece on the table against the fence (13)
■
and adjust its position so that the pencil mark is on
the laser line.
Use the vice (12) to secure the workpiece.
■
Loosen the slide lock knob (21).
■
Grasp the operating handle (25) and pull the blade to
■
the foremost position.
Squeeze the power trigger (3) and allow the saw to
■
reach full speed (Fig. 1).
Press and hold the lower guard release lever (20)
■
(Fig. 1).
Push the saw handle all the way down and cut
■
through the leading edge of the workpiece.
Gently push the saw towards the fence until it
■
reaches the aftermost position.
Release the trigger (3) and allow the saw to stop
■
completely before raising the blade out of the
workpiece (Fig. 1).

COMPOUND MITRE CUTTING (Fig. 14)
A compound mitre cut is a cut made using a mitre
■
angle and a bevel angle at the same time. This type
of cut is used to make picture frames, cut molding,
make boxes with sloping sides, and for certain roof
framing cuts.
To make this type of cut the control arm on the mitre
■
table must be rotated to the correct angle and the
saw arm must be tilted to the correct bevel angle.
Care should always be taken when making
compound mitre setups due to the interaction of the
two angle settings.
Adjustments of mitre and bevel settings are
■
interdependent with one another. Each time you
adjust the mitre setting you change the effect of the
bevel setting. Also, each time you adjust the bevel
setting you change the effect of the mitre 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.
To aid in making the correct settings, the compound
■
angle setting chart is as provided (Fig. 17).
Each B (Bevel) and M (Mitre) Setting is Given to the
Closest 0.005°.

CUTTING CROWN MOLDING

Your compound mitre saw does an excellent job of
■
cutting crown molding. In general, compound mitre
saws do a better job of cutting crown molding than
any other tool made.
In order to fit properly, crown molding must be
■
compound mitred with extreme accuracy.
The two contact surfaces on a piece of crown molding
■
that fit flat against the ceiling and the wall of a room
are at angles that, when added together,
equal exactly 90°. Most crown molding has a top rear
angle (the section that fits flat against the ceiling)
of 52° and a bottom rear angle (the section that fits
flat against the wall) of 38°.
