Porter-Cable 345 Instruction Manual page 17

For narrow rip cuts, use the rip guide,
available as an accessory. You can
guide the saw by keeping the inner
face of the rip guide (Fig. 14) tight
against the edge of the board.
For making wider cuts (plywood or
other wide sheets), tack or clamp a
wooden guide strip on the workpiece
to guide the right edge of the saw
base (Fig. 16).
NOTE: You will have to adjust the depth of cut 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,
but the blade is set at an angle
between 0° and 45° (Fig. 17).
The bevel cut made at an angle to
the edge of a board is called a
compound cut. Certain compound
cuts require the manual retraction of
the telescoping guard to allow the
blade to enter or cut through the
workpiece.
Use the lever (A) (Figs. 15A and 15B) provided on the
telescoping guard to retract the telescoping guard manually.
POCKET CUTS (PLUNGE CUTTING)
A pocket cut is made inside the area
of the workpiece and not starting
from the edge. Mark the area clearly
with lines on all sides. Adjust your
blade for the correct depth of cut.
Start near the corner of one side and
place front edge of the saw base
firmly on the workpiece. Hold the rear
of the saw up so that the blade clears
the workpiece. Push the telescoping
guard lever all the way back so that
the blade is exposed (Fig. 18). Start
the motor and lower the blade into the work. After the blade has cut through
and the base rests flat on the work, follow the line to the corner. Use a
keyhole or bayonet saw to cut the corners clean.
When making pocket cuts in stone, tile, etc., using the dry
diamond blade, exercise extreme care to prevent twisting to reduce the
possibility of blade damage.
