TO INSTALL THE BLADE

1. Place inner clamp washer (N) on saw spindle with the large flat
surface facing out toward the blade (Fig. 4).
2. Retract the lower blade guard (G) and place blade on saw spindle
against the inner clamp washer, making sure that the blade will
rotate in the proper direction (the direction of the rotation arrow on
the saw blade and the teeth must point in the same direction as the
direction of rotation arrow on the saw). Do not assume that the
printing on the blade will always be facing you when properly
installed. When retracting the lower blade guard to install the blade,
check the condition and operation of the lower blade guard to
assure that it is working properly. Make sure it moves freely and
does not touch the blade or any other part, in all angles and
depths of cut.
3. Place outer clamp washer (O) on saw spindle with the large flat
surface against the blade with beveled side facing out.
4. Thread blade clamping screw (H) into saw spindle by hand (screw
has left-hand threads and must be turned counterclockwise to
tighten).
