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.
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).
5. Depress the blade lock (K) while turning the saw spindle with the
blade wrench until the blade lock engages and the blade stops
rotating (Fig. 5).
6. Tighten the blade clamping screw firmly with the blade wrench.
NOTE: Never engage the blade lock while saw is running, or engage
in an effort to stop the tool. Never turn the saw on while the blade lock
is engaged. Serious damage to your saw will result.
