Receiving The Saw; Installation & Assembly; Cast Iron Extensions; Mounting Blade - Powermatic 74A Instruction Manual & Parts List

RECEIVING THE SAW

Remove the saw from its shipping carton and check
for damage. Report any damage to your distributor
immediately. Accessories and rails were shipped in
separate cartons. Read the instruction manual thor-
oughly for assembly, alignment, maintenance and
safety instructions.
NOTE: Exposed metal parts such as the top and
extension wings have been given a protective coating
at the factory. This should be removed with a solvent
(such as mineral spirits) once the machine has been
assembled.
INSTALLATION & ASSEMBLY
Mount the machine on a solid foundation and secure
to the floor with high-quality lag screws through the
four holes provided in the machine's base.

CAST IRON EXTENSIONS

1. Mount the cast iron extensions using the (6)
1/2 x 1-1/4" hex. hd. cap screws and lock washers.
Holding the wing in upright position to the saw table,
insert the middle screw and lock washer first but do
not tighten completely.
2. Pivot the wing to level position and insert the
outside screws. Do not tighten completely.
3. Level the extension with the table, using a
straight edge so that they form a flat plane with the
table top.
4. Tighten all screws.

MOUNTING BLADE

If your blade came uninstalled, refer to "Changing Saw
Blades," page 9. NOTE: Blade must be mounted
before making rail and fence adjustments.
RAILS & ACCU-FENCE

Fence ® to assemble rails and fence at this point.)
SPLITTER & GUARD ASSEMBLY

shaft through slot in rear of saw and into hole in trun-
nion, Figure 1. Make sure the square head setscrew
is backed out enough to allow easy insertion.

into the groove of the shaft as shown in Figure 2.
(NOTE: The groove will be in the proper position if the
end of the shaft is made flush with the opposite side of
the trunnion hole.) Tighten the locknut. The upright
member of the rear splitter support must be on the left
side of the shaft (observed from the saw's front).
