Operating Procedures Ripping - Powermatic 64S Operating Instructions And Parts Manual

c. Do not use the mitre gauge and rip fence in the
same operation unless provision is made of a facing
board on the fence to allow the cutoff section of the
workpiece to come free before the cut is started. (See
page 24).
d. Check the operation of the anti-kickback pawls
before starting a cut. If the pawls do not stop the re-
verse motion of a workpiece, resharpen all the points.
e. Keep your face and body out of line with poten-
tial 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 blade 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 block
when ripping short, narrow (6" width or less), or thin
work. Use a push stick or mitre gauge hold-down when
dadoing or molding as shown in Figure 32.
5. For added safety in crosscutting use an auxil-
iary wood facing board attached to the mitre gauge
using the holes provided as shown in Figure 33.
6. Never use the fence as a length stop when cross-
cutting. Do not hold on to or touch the free end or
cutoff section of a workpiece. Throughout the sawing
operations, the cutoff 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 ei-
ther hand to hold down the workpiece.
8. Use the mitre gauge on the left hand side of the
saw blade when doing mitre 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 aligned with the saw blade using
the fence both as a guide and a positioning device to
ensure the desired width of cut as shown in Figure 34.
Many manufacturers make blades specifically designed
for this operation.
CAUTION: Before starting a ripping cut, be
!
sure the fence is clamped securely and
properly aligned.
