the blade is at the desired height, tighten lock knob (A).
To lower the blade, loosen lock knob (A) Fig. 44, and turn
the handwheel (B) counterclockwise. NOTE: One full turn
of the handwheel will change blade height approxi-
mately 1/4".
TILTING THE BLADE
To tilt the saw blade for bevel cutting, loosen lock knob
(C) Fig. 44, and turn the tilting handwheel (D). When the
desired blade angle is obtained, tighten lock knob (C).
6. Adjust the pointer (D) Fig. 46, to point to the zero
degree mark on the scale by loosening screw (E),
adjusting pointer (D), and tightening screw (E).
7. Turn the blade tilting handwheel clockwise as far as
it will go and using a combination square, check to see
if the blade is at 45 degrees to the table.
8. If the blade is not at 45 degrees to the table, loosen
set screw (F) Fig. 45, and turn blade tilting handwheel
until you are certain the blade is 45 degrees to the table.
Turn set screw (F) clockwise until it bottoms.
ADJUSTING 90 DEGREE AND
45 DEGREE POSITIVE STOPS
Your saw is equipped with positive stops that will quickly
and accurately position the saw blade at 90 degrees and
45 degrees to the table. To check and adjust the positive
stops, proceed as follows:
1. DISCONNECT MACHINE FROM
POWER SOURCE.
2. Raise the saw blade to its highest position.
3. Set the blade at 90 degrees to the table by turning
the blade tilting handwheel counterclockwise as far as it
will go.
4. Using a combination square (A) Fig. 45, check to
see if the blade is at 90 degrees to the table surface as
shown.
5. If the blade is not at 90 degrees to the table, loosen
set screw (B) Fig. 45 with a hex wrench, and turn the
blade tilting handwheel until you are certain the blade is
at 90 degrees to the table. Turn set screw (B) clockwise
until it bottoms.
