Tilting Mechanism; General Maintenance - Powermatic 72A Instruction Manual & Parts List

If the saw arm has been relocated, the table may have
to be realigned so as to provide clearance between
the saw blade and table insert slot. The splitter will
also have to be realigned.
NOTE: The saw arm setscrew must be tight to avoid
the possibility of movement which could cause the
blade to hit the insert.
TILTING MECHANISM ADJUSTMENT
If binding occurs in the tilting mechanism, clean off
the saw dust and pitch accumulation and re-grease.
If binding continues, check the alignment and read-

just as required to center worm with the worm gear
segment on the trunnion.
If there is excessive play, loosen bracket mounting
screws (A) and turn adjustment screw (B) clockwise
to raise pinion. See Figure 21. A tight mesh without
binding is ideal. Retighten mounting screws and check
over the 90 degree to 45 degree range of tilt for exces-
sive play or binding. Readjust if required.

GENERAL MAINTENANCE

Good saw operation requires periodic preventive main-
tenance.
Keep the inside of the cabinet and trunnion area clean.
A stiff brush will remove sawdust before it cakes and
pitch or gum is easily removed with a commercial sol-
vent or with a good oven cleaner. To accomplish this,
remove the table by removing the three mounting
screws and exposing the working mechanisms of the
saw. After cleaning the tilting and raising worm and
worm gear segments and the trunnions, grease these
three areas with a good grade non-hardening grease.
Check periodically for excessive play in the tilting and
raising mechanism and in the saw arbor and re-adjust
as required.
Check periodically for belt tension and wear. Read-
just or replace belt as required.
The table surface must be kept clean and free of rust
for best results. Although some users prefer a wax
coating, white talcum powder applied with a black-
board eraser rubbed in vigorously once a week will fill
casting pores and form a moisture barrier. This method
provides a table top that is slick and allows rust rings
to be easily wiped from the surface. Important also is
the fact that talcum powder will not stain wood or mar
finishes as wax pickup does.
