Where possible, keep your face and body out
of line with potential kickbacks including when
starting or stopping the machine.
Figure 8-1
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" (150mm) width or
less, or thin work. Use a push block or miter gauge
hold-down when dadoing or molding.
For increased safety in crosscutting, use an
auxiliary wood facing (Figure 8-2) attached to the
miter gauge, using the slots or holes provided in
the gauge.
Figure 8-2
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 the
possibility of the work binding and the resulting
kickback.
9.2 Rip sawing
Ripping is where the workpiece is fed with the grain
into the saw blade using the fence as a guide and
a positioning device to ensure the desired width of
cut (Figure 8-3).
Figure 8-3
Before starting a ripping 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.
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.
The rip fence (A, Figure 8-4) should be set for the
width of the cut (C) by using the scale on the front
rail, or by measuring the distance between blade
(B) and fence (A). Stand out of line with saw blade
and workpiece to avoid sawdust and splinters
coming off the blade or a kickback, if one should
occur.
If the work piece 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. If it
is warped, turn the hollow side down.
Do not
attempt to cut boards with significant warp.
