CROSS-CUTTING
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 through 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.
CROSS-CUT STOP
A block of wood placed at (B) Fig. 53 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.

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. 54 shows a typical miter cutting
operation on the radial saw.
