OPERATING INSTRUCTIONS
FOR TABLE SAWS
(NOTE: Your table saw may not resemble exactly
the machine shown in these photos, but the proce-
dures will be identical.)
1. Familiarize yourself with the location and opera-
tion of all controls and adjustments and the use of
accessories such as the mitre gauge and rip fence.
2. Serious injury can result from kickbacks which
occur when a work piece binds on the saw blade or
binds between the saw blade and rip fence or other
fixed object. This binding can cause the work piece
to lift up and be thrown toward the operator. Listed
below are the conditions which can cause kickbacks:
- Confining the cutoff piece when crosscutting or rip-
ping.
- Releasing the work piece before completing the op-
eration or not pushing the work piece all the way past
the saw blade.
- Not using the splitter when ripping or not maintain-
ing alignment of the splitter with the saw blade.
- Using a dull saw blade.
- Not maintaining alignment of the rip fence so that it
tends to angle toward rather than away from the saw
blade front to back.
- Applying feed force when ripping to the cutoff (free)
section of the work piece instead of the section be-
tween the saw blade and fence.
- Ripping wood that is twisted (not flat), or does not
have a straight edge, or a twisted grain.
3. To minimize or prevent injury from kickbacks:
- Avoid conditions listed above.
- Wear a safety face shield, goggles, or glasses.
- Do not use the mitre gauge and rip fence in the
same operation unless provision is made by use of a
facing board on the fence so as to allow the cutoff
section of the workpiece to come free before the next
cut is started (See Figure 30).
- As the machine receives use, the operation of the
anti-kickback pawls should be checked periodically.
See Figure 22. If the pawls do not stop the reverse
motion of a workpiece, resharpen all the points.
