3. To adjust, loosen the locknut (B) Fig. 25, and turn the screw (C)
until the head of the screw (C) contacts the casting (D) when
blade is 90° degrees to the table. Tighten the locknut (B).
4. Loosen the bevel lock handle. Move the cutting arm all the way
to the left bevel position and tighten the bevel lock handle.
5. Use a combination square (A) Fig. 26 to see if the blade is at 45°
to the table.
6. To adjust, loosen the locknut (E) Fig. 27, and turn the screw (F)
until it contacts the casting (G). Tighten the locknut (E).
7. Check to see that the bevel pointer (P) Fig. 28 is pointing to the
45° mark on the bevel scale (S) Fig. 26. To adjust the bevel
pointer (P) Fig. 28, loosen the screw (H) and adjust pointer (P).
Tighten the screw (H) securely.
8. These positive stops enable you to rapidly position the blade at
the 90° and 45° bevel angle to the table.
ADJUSTING THE TENSION OF THE CUTTINGHEAD RETURN
SPRING
WARNING: CUTTING HEAD MUST RETURN QUICKLY TO
THE UP POSITION. DISCONNECT MACHINE FROM POWER
SOURCE.
The tension of the cuttinghead return spring was adjusted at the
factory so that the cuttinghead returns to the "up" position after
cutting.
To adjust the spring tension, loosen the locknut (A) Fig. 29 and turn
the screw (B) (clockwise to increase or counterclockwise to decrease
the spring tension). After adjustment, tighten the locknut (A).
ADJUSTING SLIDING FIT BETWEEN CUTTINGHEAD ARM AND
TRUNNION
After a long period of time, an adjustment of the sliding fit between
the cuttinghead arm (B) Fig. 29A, and the trunnion (C) may be
necessary. To adjust, turn the nut (D). This adjustment should not
be so tight that it restricts the sliding movement of the cuttinghead
arm (B) or so loose that it affects the accuracy of the saw cut.
ADJUSTING THE LOWER BLADE GUARD
WARNING: DISCONNECT THE MACHINE FROM POWER
SOURCE.
This machine incorporates a blade guard (A) Fig. 29B to cover the
rear section of the blade. After an extended period of use, the
movable lower blade guard may not operate smoothly when the
cuttinghead is lowered. This can be corrected by adjusting nut (B)
until the lower blade guard moves freely.
WARNING: Overtightening the nut could impair guard
movement.
NOTE: This unit has been designed with an articulating rear guard.
Before contacting the workpiece, the rear guard will rotate upward
to expose more of the blade as the cuttinghead is lowered.
WARNING: DO NOT REMOVE ANY OF THE BLADE
GUARDS.
WARNING: Make sure that all guards are in place and
functioning properly before operating the saw.
WARNING: Make sure that the fences are clear of the
guard and blade before operating the saw.
