ATTACHING & REMOVING BLADES
1. BE SURE SAW IS DISCONNECTED FROM POWER SUPPLY!
2. To remove blade clamping screw (Fig. 1):
—a. ON NEW SAWS (without blade attached). Turn screw counter-clockwise with
blade wrench provided. If screw does not loosen easily from spindle, tap the outer
end of the wrench sharply in a counter-clockwise direction with a piece of wood
to "free" the screw threads. Remove screw and outer clamp washer.
—b. ON SAWS WITH BLADE ATTACHED. Using the retracting lever, retract the
lower blade guard and place the Saw on a piece of scrap lumber as shown in
Figure 2. Press down on the Saw so that the blade teeth dig slightly into the lum-
ber and prevent the blade from turning. Then, with the blade wrench provided,
turn the clamping screw counter-clockwise and remove the screw and outer clamp
washer. Disengage the blade teeth from the lumber, and with the lower blade
guard still retracted, lift off the blade.
3. To attach the blade: Place inner clamp washer on spindle if previously re¬
moved. Retract lower blade guard and place blade over inner clamp washer with
printed side of blade out (teeth at bottom of blade pointing forward). Fit outer
clamp washer onto spindle . . . "flats" on the outer washer must mesh with the
"flats" on the spindle. Thread on clamping screw firmly by hand to hold washers
in position. Place Saw on piece of scrap lumber as shown in Figure 2 and press
down on the Saw so that blade teeth dig slightly into wood and prevent the blade
from turning. Tighten clamping screw (clockwise) firmly with the blade wrench.
NOTE: An alternate way to keep the blade from turning, when tightening or loosen¬
ing the blade screw, is to hold a large nail through the hole in the blade and
against the forward part of the shoe. Rest the nail on top of the shoe when tight¬
ening, against the bottom when loosening. CAUTION: Remove nail before con¬
necting plug.
