bearing replacement, it should be done by a
qualified service technician. Call your customer

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
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.
