OPERATING INSTRUCTIONS
MACHINE INSTALLATION ADJUSTMENTS AND MAINTENANCE cont'd
BLADE RAISING MECHANISM ADJUSTMENT:
If binding accurs, clean off all sawdust and pitch
build-up and re-Iubricate with a good non·hardening
grease such as Fisk Company Lubriplate. If binding
continues, check the fit-up of the worm and worm
gear segment. The worm must be centered with the
worm gear segment. If it is not centered, loosen the
saw raising arm setscrews and move the arm as re-
quired (Fig. 15) and relock. If saw arm has been re-
located, the table may have to be realigned so as to
provide clearance between the saw blade and table
insert slot and the splitter will have to be realigned.
NOTE: The saw arm setscrew must be tight to a-
void the possibility of movement which could cause
the blade to hit the insert.
SPLITTER ALIGNMENT:
One of the most critical adjustments to help avoid
kickbacks is the splitter alignment. It should be
checked and readjusted, if required after each blade
change. To align the splitter to the blade use a com-
bination square against the side of the raised up miter
gauge bar and slide the scale against the top of the
tooth. Check the splitter for parallelism to the miter
slot and readjust if required, and for clearance. Move
the miter gauge to the opposite side of the blade and
using the combination square, slide the scale against
the top of a tooth. Check for clearance. Clearance
should be approximately equal on both sides of the
blade (Fig. 16) The insert will have to be removed to
get at the adjustment jackscrew mounted in the cen-
ter trunnion.
INSERT ADJUSTMENT:
Adjust the set screws as required in the insert (Fig.17)
to insure that the insert is stable and flush with or :
slightly below the table top.
