ripping guide is set a distance away from the saw
equal to the width of the strip to be ripped off. It is
then placed against the edge of the piece as a guide for
the saw. To make a bevel angle cut up to 45° (view
B), you just set the bevel adjustment knob to the angle
you want and cut down the line. To make a pocket cut
(views C and D), a square cut in the middle of a piece
of material, you retract the guard back and tilt the saw
so that it rests on the front of the base. Then, lowering
the rear of the saw into the material, hold it there until
it goes all the way through the wood. Then, follow
Observe the following safety precautions when
operating a circular saw:
Dont force the saw through heavy cutting
stock. If you do, you may overload the motor
and damage it.
Before using the saw, carefully examine the
material to be cut and free it of nails or other
metal objects. Cutting into or through knots
should be avoided, if possible.
Disconnect the saw from its power source
before making any adjustments or repairs to
the saw. This includes changing the blade.
Make sure all circular saws are equipped with
guards that automatically y adjust themselves to
the work when in use so that none of the teeth
protrude above the work. Adjust the guard
over the blade so that it slides out of its recess
and covers the blade to the depth of the teeth
when you lift the saw off the work.
Wear goggles or face shields while using the
saw and while cleaning up debris afterward.
Grasp the saw with both hands and hold it
firmly against the work. Take care to prevent
the saw from breaking away from the work and
thereby causing injury.
Inspect the blade at frequent intervals and
always after it has locked, pinched, or burned
the work. Disconnect the saw from the power
source before performing this inspection.
Inspect daily the electric cords that you use for
cuts or breaks. Before cutting boards, make
sure the cord is not in the way of the blade.
The saber saw (figure 3-18) is a power-driven
jigsaw that cuts smooth and decorative curves in
wood and light metal. Most saber saws are light-duty
machines and not designed for extremely fast cutting.
There are several different, easily interchangeable
blades (figure 3-19) designed to operate in the saber
saw. Some blades are designed for cutting wood and
some for cutting metal.
The best way to learn how to handle this type of
tool is to use it. Before trying to do a finished job
with the saber saw, clamp down a piece of scrap
plywood and draw some curved as well as straight
lines to follow. You will develop your own way of
