terference between moving and stationary
parts of the saw. Do not operate the saw in
the following range of miter and bevel combi-
nations: Left Bevel 45° to 47° PLUS Right
Miter 40° to 42°. These miter and bevel com-
binations may result in interference between
the sliding and stationary parts of the saw or
between the sliding parts and the work piece.

What's a Compound Cut?

• A "compound cut" is a single cross-cut
made with the saw blade preset at two an-
gles combining a miter angle (relative to the
vertical fence) with a bevel angle (relative to
the horizontal table).
• Miter angles will be with the table rotated
away from 0° and within this saw's range
from 52° left to 60° right.
• A bevel angle is when the blade is tilted
away from 0°. This saw's range is from 47°
left to 47° right. NOTE: If the bevel detent
pin automatically engages at 31.6° and pre-
vents tilting the saw to another angle, sim-
ply pull it to the front and rotate its cross
pin 1/4 turn so it rests in the disengaged po-
sition. If pin is sticking in, tilt and rock saw
head side to side as you pull on it.
• A compound cut can be made as a chop cut
or a slide cut.
Follow these instructions for making
your compound cut:
1. Extend the base extensions and fence. (See
Sliding Fences and Base Extensions on page
34 and 35).
2. Properly position workpiece. Make sure
workpiece is clamped firmly against the
table or the fence (figure 54).

Saw Operations

Compound Cuts

For compound cutting, adjust sliding fence clear of blade path and guard
system.
Before sawing, always
check that there is no in-
Clamp
Bevel Angle
Sliding Scale
Base
Use clamping position
that does not interfere
with operation. Before switching on, lower
head assembly to make sure clamp clears
guard and head assembly.
Be aware of the path of
the saw blade. Make a dry
run with the saw Off by conducting a simu-
lated cutting cycle, and observe the projected
path of the saw blade. Keep hands at least six
(6) inches away from the projected path of
the saw blade.
3. Set miter and bevel angles according to the
instructions on page 41 – 47 for miter and
bevel cuts.
4. Follow the procedures for chop cut or slide
cut.
5. Wait until blade comes to a complete stop
before returning head assembly to the
raised position and/or removing workpiece.

quires compound cuts. See cutting crown
