TO INSTALL THE BLADE (FIG. A–D)
1.  Using the lower guard lever (k), retract the lower blade 
guard (i) and place blade on saw spindle against the inner 
clamp washer (o), 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.
2.  Place outer clamp washer (n) on saw spindle with the 
large flat surface against the blade and the wording on the 
outer clamp washer facing you.
3.  Thread blade clamping screw (j) into saw spindle by 
hand (screw has right-hand threads and must be turned 
clockwise to tighten).
4.  Depress the blade lock (c) while turning the saw spindle 
with the blade wrench until the blade lock engages and the 
blade stops rotating.
5.  Tighten the blade clamping screw firmly with the blade 
wrench (s).
