Powermatic 1791228K, 64A operating instructions Operating Procedures, Ripping

•Check the operation of the anti-kickback pawls before starting a cut. If the pawls do not stop the reverse motion of a workpiece, resharpen all the points.

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

3.Dull or improperly sharpened blades and blades with gum or resin adhering to them may cause an accident with the tilting arbor saw. Never use a cracked saw blade. The use of a sharp, well maintained, and correct cutting tool for the operation will help avoid kickbacks.

4.Support the work properly and hold it firmly against the gauge or fence. Use a push stick or push block when ripping short, narrow (6" width or less), or thin work. Use a push block or miter gauge hold-down when dadoing or molding. (Figure 36)

5.For added safety in crosscutting use an auxiliary wood facing attached to the miter gauge using the holes provided. (Figure 37)

6.Never use the fence as a length stop when crosscutting. Do not hold on to or touch the free end or cutoff section of a workpiece. On through-sawing operations, the cut-off section must not be confined.

7.Always keep your hands out of line with the saw blade and never reach past the rotating blade with either hand to hold down the workpiece.

8.Use the miter gauge on the left hand side of the saw blade when doing miter or compound miter cuts to provide more hand clearance and safety.

Operating Procedures

Ripping

1.Ripping is a sawing process where the workpiece is fed with the grain into the saw blade using the fence both as a guide and a positioning device to ensure the desired width of cut (Figure 38).

2.Many manufacturers make blades specifically designed for this operation.

Before starting a ripping cut, be sure the fence is clamped securely and properly aligned.
