SAFETY RULES
KICKBACKS
A kickback occurs during a rip-type operation when a part or all of workpiece is
thrown back violently toward operator.
Keep your face and body to one side of the saw blade, out of line with a possible
kickback.
Kickbacks and possible injury from them can usually be avoided by:
• Maintaining rip fence parallel to saw blade.
• Keeping saw blade sharp. Replace or sharpen anti-kickback pawls when points
become dull.
• Keeping saw blade guard, spreader, and anti-kickback pawls in place and
operating properly. The spreader must be in alignment with the saw blade and
the pawls must stop a kickback once it has started. Check their action before
ripping.
• Avoiding the use of twisted pieces, or pieces that warped or does not have a
straight edge to guide along the rip fence.
• Not releasing work until you have pushed it all the way past the saw blade.
• Using a push stick for ripping widths less than 6 inches.
• Not confining the cutoff piece when ripping or crosscutting.
PROTECTION: EYES, HANDS, FACE, BODY, EARS
• If any part of your saw is missing, malfunctioning, or has been damaged or broken
(such as the motor switch, electronic controls, other operating control, a safety
device or power cord), cease operating immediately until the particular part is
properly repaired or replaced.
• Wear safety goggles and a face shield or dust mask if operation is dusty. Wear ear
plugs or muffs during extended periods of operation.
• Small loose pieces of wood or other objects that contact the rear of the revolving
blade can be thrown back at the operator at excessive speed. This can usually be
avoided by keeping the guard and spreader in place for all through-sawing
operations (sawing entirely through the work) and by removing all loose pieces
from the table with a long stick of wood immediately after they are cut off.
• Use extra caution when the guard assembly is removed for resawing, dadoing,
or rabbeting—replace guard as soon as that operation is completed.
• Never turn the saw ON before clearing the table of all tools, wood scraps, etc.,
except the workpiece and related feed or support devices for the operation
planned.
• Never place your face or body in line with the cutting tool.
• Never place your fingers or hands in path of saw blade.
• For rip or rip-type cuts, the following end of a workpiece to which a push stick or
push board is applied must be square (perpendicular to the fence) in order that
feed pressure applied to the workpiece by the push stick or block does not cause
the workpiece to come away from the fence, and possibly cause a kickback.
• During rip and rip-type cuts, workpiece must be held down on table and against
fence with a push stick, push block, or featherboards, as applicable (see Figures
1a and 1b).
Push Stick: A safety device used to push the workpiece through a cutting operation.
Used most often when rip cutting thin workpieces.
The push stick and push block examples shown below are useful for keeping hands
and fingers away from saw blade during ripping, rabbeting and dadoing. Apply
downward pressure and push workpiece through the cut and past the blades.
Several other configurations may be suitable for safe operation. Featherboards are
used to keep the work in contact with the rip fence or table during the cutting
operation. Use of featherboards can help to prevent kickbacks and binding.
Featherboards should be used for all "non through-sawing" operations.
• Never reach in back of the blade with either hand to hold down or support the
workpiece, remove wood scraps, or for any other reason. Avoid awkward
