Changing Blades

TO INSTALL THE BLADE (FIG. 4, 5)
1. Place inner clamp washer (N) on saw spindle with the large flat
surface facing out toward the blade (Fig. 4a, 4b).
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 lower
blade guard). 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.
