WARNING
Bevel Angle Stops and Detents
The saw has bevel angle stops that accurately
stop at critical angles: 45° left, 0°, and 45°. It
comes factory-set and should not need to be
adjusted. However, after extensive use or if the
tool has received a hard impact, it may require an
adjustment.
The saw has a bevel angle detent pin which can
only be engaged at 33.9° left or right - this is the
bevel angle required when cutting 38° "spring
angle" crown molding flat on the table. NOTE: If
the bevel detent pin automatically engages at
33.9° and prevents tilting the saw to another
angle, simply pull it to the front and rotate its cross
pin 1/4 turn so it rests in the disengaged position.
If pin is sticking in, tilt and rock saw head side to
side as you pull on it (see Figure 52).

Setting Saw to Make a Bevel Cut
1. Lift up the bevel lock lever to unlock (see item 14
– page 8).
2. Choose the desired bevel range using the bevel
range selector knob. NOTE: If in the 0° position
and moving to "0-45° Range," it may be necessary
to move the head assembly slightly to the left
before the selector knob can be turned.
3. Grasp the main handle and tilt the saw head
assembly to the desired angle while watching one
of the bevel angle pointers – watch the right
pointer when tilting to the left or the left pointer
when tilting to the right.
4. Continue to hold saw and push down on the bevel
lock lever (with your left hand) to lock. Let go of
tool.
5. Follow the chop cut or slide cut procedures in this
manual.
