Support the work properly and hold it firmly
against gauge or fence. Use a push stick or
push block when ripping short, narrow (6"
width or less), or thin work. Use a push block
or miter gauge hold-down when dadoing or
molding.
Never use the fence as a length stop when
crosscutting. Do not hold or touch the free
end or cutoff section of a workpiece. On
through-sawing operations, the cutoff section
must NOT be confined.
Always keep your hands out of line of the
saw blade and never reach back of the
cutting blade with either hand to hold the
workpiece.
Bevel ripping cuts should always be made
with the fence on the right side of saw blade
so that the blade tilts away from the fence
and minimizes possibility of the work binding
and the resulting kickback.
9.2 Rip sawing
Ripping is feeding the workpiece with the grain into
the saw blade using the fence or other positioning
device as a guide to ensure desired width of cut
(Figure 9-2).
Before starting a rip cut, verify
that fence is clamped securely and aligned
properly.
Never rip freehand or use miter gauge in
combination with the fence.
Never rip workpieces shorter than the saw
blade diameter.
Never reach behind the blade with either
hand to hold down or remove the cutoff piece
with the saw blade rotating.
Figure 9-2
Always use blade guard, splitter/riving knife and
anti-kickback pawls. Make sure splitter/riving knife
is properly aligned. When wood is cut along the
grain, the kerf tends to close and bind on the blade
and kickbacks can occur.
Note: A warning decal is affixed to the guard to
remind
the
operator
procedures.
The rip fence should be set for the width of the cut
by using the scale on the front rail, or by measuring
the distance between blade (A) and fence (B).
Stand out of line with saw blade and workpiece to
avoid sawdust and splinters coming off the blade or
a potential kickback.
If the workpiece does not have a straight edge, nail
an auxiliary straight edged board on it to provide
one against the fence. To cut properly, the board
must make good contact with the table. Do not
attempt to cut warped boards.
In ripping, use one hand to hold the board down
against the fence or fixture, and the other to push it
into the blade between blade and fence. If
workpiece is narrower than 6" or shorter than 12",
use a push stick or push block to push it through
between fence and blade (Figure 9-4). Never push
in a location such that the pushing hand is in line
with the blade. Move the hand serving as a hold-
down a safe distance from blade as cut nears
completion.
For very narrow ripping where a push stick cannot
be used, use a push block or auxiliary fence.
Always push the workpiece completely past the
blade at the end of a cut to minimize the possibility
of a kickback.
