Bevel Cutting - Porter-Cable SAW BOSS 345 Instruction Manual

Do not force the cut. Let the saw do the cutting at the rate of speed permitted
by the type of cut and the material being cut. When the cut is completed,
release the switch and allow the blade to stop before lifting the saw from the
work. On through-cuts, be sure the lower blade guard is closed, before setting
the saw down.
CROSS-CUTTING
Cutting directly across the grain of a piece of lumber is called crosscutting.
Fig. 14 illustrates a crosscut operation. Position the work so that the cut will
be on the left, as shown.
RIPPING
Cutting wood lengthwise is referred to as ripping. This operation is performed
in the same manner as crosscutting with the exception of supporting the
material to be cut. If material is supported on a large table, bench or floor,
several pieces of scrap stock approximately one inch thick should be placed
beneath the material to allow clearance for the portion of the saw blade that
extends thru the material. Large sheets of paneling or thin plywood supported
on saw horses should have 2 x 4's placed lengthwise between the horses and
the material, to prevent it from sagging in the center.
For narrow rip cuts, the rip guide, available as an accessory can be used. The
saw is guided by keeping the inner face of the rip guide Fig. 13 tight against
the edge of the board.
For making wider cuts, such as might be made in plywood and wide sheets, a
wooden guide strip, against which the right edge of the saw base can be
guided, can be tacked or clamped to the work, as shown in Fig. 15. NOTE: The
depth of cut must be adjusted to allow for the thickness of the wooden guide
strip.

BEVEL CUTTING

Bevel cuts are made in the same manner as crosscuts and rip cuts. The only
difference is that the blade is set at an angle between 0° and 45°, as shown
in Fig. 16.
The bevel cut made at an angle to the edge of a board is called a compound
cut. There are certain compound cuts, on which it may be necessary to
manually retract the telescoping guard to allow the blade to enter into and/or
through the cut.
