9.9Arbor/Arbor Bearing Removal

The saw arbor is press fitted in the saw raising arm 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 front cover.

10.0Operations

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.

10.1Kickback 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:

ˆConfining the cutoff piece when crosscutting or ripping.

ˆReleasing workpiece before completing operation or not pushing workpiece all the way past saw blade.

ˆNot using splitter/riving knife when ripping or not maintaining alignment of splitter/ riving knife with saw blade.

ˆUsing dull saw blade.

ˆNot maintaining alignment of rip fence so that it tends to angle toward rather than away from saw blade front to back.

ˆApplying feed force when ripping to the cutoff (free) section of workpiece instead of the section between saw blade and fence.

ˆRipping wood that is twisted (not flat), or does not have a straight edge, or has twisted grain.

To minimize or prevent injury from kickbacks:

ˆAvoid conditions listed above.

ˆWear a safety face shield, goggles, or safety glasses.

ˆDo 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).

ˆAs 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

ˆWhere possible, keep your face and body out of line with potential kickbacks, including when starting or stopping the machine.

ˆDull, badly set, improper, or improperly filed cutting tools, and cutting tools with gum or resin adhering to them can cause
