CHECKING FOR ACCURACY
A good craftsman makes periodic checks of his machine
to be sure that related parts are in correct alignment.
Here is what to look for and good methods for checking.
1 - AT "0" TRUNNION SETTING, THE TABLE MUST
BE SQUARE TO THE SAW BLADE
This is checked with the table as low as possible and
locked in position about 1/8" away from the saw blade.
Be sure the square used for checking rests flat against
the blade and that it seats between the teeth.
IF TABLE, WITH TRUNNION SET AT "0," IS NOT
EXACTLY 90 DEGREES TO SAW BLADE
Loosen table tilt lock and pull out trunnion plunger ("A",
Fig. 16). Set table at exactly 90 degrees and secure table
tilt lock. Push in plunger turn auto - stop set screw until
it just bears against plunger (Fig. 16). Adjust trunnion
vernier plate until middle calibration is lined up exactly
with "0" mark on trunnion.
Pull out plunger and tilt table to the right until middle calibration on trunnion vernier plate lines up exactly with
45 degree mark on trunnion. Lock table. Push in plunger and adjust auto-stop set screw until it just bears against
plunger.
2 TABLE SLOTS MUST BE PARALLEL TO SAW
BLADE. Check by setting table as low as possible in normal
sawing position. Place miter gauge in either slot and clamp
Allen wrench to its face so that it extends just enough to
touch one tooth of the blade set In direction of miter gauge
(Fig. 17). Mark tooth with a pencil or chalk. (Miter gauge
stop rod, if available, may be used in place of Allen wrench.)
Rotate saw blade backwards by hand until that SAME tooth
is at rear of the insert slot.
