 Applying feed force when ripping to the
cutoff (free) section of workpiece instead of
the section between saw blade and fence.
 Ripping wood that is twisted (not flat), or
does not have a straight edge, or has
twisted grain.
To minimize or prevent injury from kickbacks:
 Avoid conditions listed above.

Wear a safety face shield, goggles, or
safety glasses.
 Do not use miter gauge and rip fence in
the same operation unless provision is
made by use of a facing board on the
fence, to allow the cutoff section of
workpiece to come free before the actual
cut begins (See Figure 37).
 As the machine
operation of the anti-kickback pawls should
be checked periodically (Figure 30). If the
pawls do not stop the reverse motion of a
workpiece, resharpen all the points.
Figure 30
 Where possible, keep your face and body
out of line with potential kickbacks,
including when starting or stopping the
machine.

Dull, badly set, improper, or improperly
filed cutting tools, and cutting tools with
gum or resin adhering to them can cause
accidents. Never use a cracked saw blade.
The use of a sharp, well maintained, and
correct cutting tool for the operation will
help avoid injuries.
 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
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.
10.2 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 31).
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 31
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 of
procedures.
The rip fence (A, Figure 32) 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.
