POWER SOURCE.
2. Remove the blade guard and spreader assembly.
NOTE: SEE THE SECTION “REMOVING BLADE
GUARD/SPREADER ASSEMBLY.”
3. Raise the saw blade to its maximum height.

tilting mechanism as far as possible to the left and
tighten the blade tilting lock handle.
5. Place a square (A) Fig. 20, on the table with one end
of the square against the blade, as shown, and check to
see if the blade is at 90 degrees to the table. If it is not,
loosen screw (B) a few turns and move the blade tilting
mechanism until the blade measures 90 degrees to the
table. Then tighten blade tilting lock handle and tighten
screw (B) until it bottoms. NOTE: CHECK TO SEE IF THE
TILT INDICATOR POINTER POINTS TO THE ZERO
MARK ON THE SCALE. ADJUST IF NECESSARY.
