CROSS-CUT STOP
A block of wood placed at (B) Fig. 74A clamped to the
track arm with a small “C” clamp will prevent
unnecessary travel (T) of the cutting-head on the track
arm. This is especially useful when performing repetitive
operations. Clamp the block of wood to the right side of
the track arm at a position which will stop the cutting-
head travel as soon as the saw blade cuts through the
workpiece.

AUXILIARY TABLE BOARD FACING
To prevent repeated cutting into the table surface which will eventually cause the table to sag, an auxiliary table board
facing can be cut and fitted to the table. It can be made from 1/4″ plywood or particle board and should be cut to a
size that will exactly cover all of the table boards in front of the fence. The auxiliary table board facing should be placed
flat on the table and butted against the table fence. Fasten it to the table with a small brad or finish nail in each corner.
The life of the table boards will be greatly extended by the use of an auxiliary facing.The auxiliary facing can readily be
replaced as often as is necessary to protect the table boards and to insure accurate and safe work.
USING A TABLE EXTENSION
When a table extension more than 24 inches long is attached to the saw, a sturdy outrigger support should be provided
or the stand or bench must be secured to the floor.
OPERATIONS
CROSS-CUTTING
The first operation which should be learned on the radial
saw is cross-cutting (Fig. 74). Cross-cutting consists of
supporting the workpiece against the fence and pulling
the saw blade through the material at right angles to it.
When cross-cutting, the track arm should be indexed at
“0” and the track arm clamp handle tightened. The fence
should be clamped between the table boards. The saw
blade is to be to the left and behind the fence. The
workpiece is placed on the table and butted against the
fence. The saw blade should be clear of the fence and
table when the machine is turned on. Then the saw blade
is lowered until it lightly cuts into the table surface. The
operator should position himself a little to the left of the
machine for better visibility while cutting. Pull the saw
blade across the work, just far enough to cut it off, and
return the saw blade to its starting position. Turn tool off.
and wait for the blade to stop before touching the cut-off
piece. The operator should always be sure to return the
cutter-head carriage to the full rear position after each
cross-cut operation.
NOTE: When cross-cutting material more than 1
″″
thick, the fence must be positioned immediately
behind the fixed front table board.

MITER CUTTING
Miter cutting is similar to cross-cutting except the
workpiece is cut off at an angle (up to 45 degrees right or
left) rather than being cut off square. The settings and
operation are performed in the same manner as cross-
cutting except that the track arm is first positioned to the
desired angle on the miter scale before it is clamped in
place. The operator should position the hand holding the
workpiece on the opposite side to the direction of the
miter so the blade is pulled through the workpiece and
away from the hand. Fig. 75, shows a typical miter cutting
operation on the radial saw.
