CAUTION: Always perform a "dry run" cut to determine if the operation being
attempted is possible before power is applied to Mitre Saw.
COMPOUND MITRE CUTTING
(Fig. 30)
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 for decorative mouldings, picture frames, and
other fine joinery.
To make this type of cut, the mitre table
must be rotated to the correct mitre
angle and the saw arm must be tilted to
the correct bevel angle.
Always take special care when making
compound mitre cuts, due to the
interaction of the two angle settings.
Adjustments of mitre and bevel settings
are dependent on one another. Each
time the mitre setting is adjusted, the
effect of the bevel setting also changes. Each time the bevel setting is adjusted, the
effect of the mitre setting is changed.
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 Make a Compound Mitre Cut with the Mitre Saw
1. Unplug the saw.
WARNING: Failure to unplug the saw could result in accidental starting,
causing serious injury.
2. Pull out the locking pin to release the saw arm.
3. Loosen the mitre-lock knob to loosen the mitre table.
4. Hold the base of the saw arm firmly and use it to rotate the mitre table while
holding the saw base steady.
5. The 0°, 15°, 22.5°, 31.6°, and 45°, left and right settings are quickly identifiable
with the stops at the angle settings.
6. When the desired mitre-table setting is achieved, tighten the mitre-lock.
WARNING: To avoid serious personal injury, always securely tighten the
mitre-lock lever before making a cut. Failure to do so could result in movement of the
control arm or mitre table while making a cut.
7. To set the bevel angle, loosen the bevel-lock knob (Fig. 1-22) by turning the knob
counter clockwise.
8. Tilt the saw arm to the desired bevel angle, as shown on the bevel scale. Bevel
angles can be set from 0°to 45°left bevel.
