9.9 Arbor/Arbor Bearing Removal

housing. If the arbor needs to be removed for
bearing replacement, it should be done by a
qualified service technician. Call your customer
service representative at the phone number on the

10.0 Operations
Familiarize yourself with the location and operation
of all controls and adjustments and the use of
accessories such as miter gauge and rip fence.
Note: The following figures may or may not show
your exact saw model, but procedures are
identical.
10.1 Kickback prevention
Serious injury can result from kickbacks which
occur when a workpiece binds on the saw blade or
binds between the blade and rip fence or other
fixed object. This binding can cause the workpiece
to lift up and be thrown toward the operator.
Listed below are conditions which can cause
kickbacks:
Confining the cutoff piece when
crosscutting or ripping.
Releasing workpiece before completing
operation or not pushing workpiece all the
way past saw blade.
Not using splitter/riving knife when ripping
or not maintaining alignment of splitter/
riving knife with saw blade.
Using dull saw blade.
Not maintaining alignment of rip fence so
that it tends to angle toward rather than
away from saw blade front to back.
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 receives use, the
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
