OPERATION
SETTINGS AND ADJUSTMENTS
TO REMOVE THE BLADE
See Figures 20 - 22.
Use the two wrenches supplied with the saw in this proce-
dure to replace the blade.
WARNING:
Unplug your saw and make sure the blade guard assembly
is installed and working properly to avoid serious personal
injury.
Raise the blade guard.
Remove the screw from the throat plate then remove the
throat plate.
Raise the blade to its full height by turning the blade
adjusting handle clockwise.
Place the open end of the small hex wrench into the slot
beside the blade. The wrench will fit over two flats on the
arbor (blade shaft).
See Figure 21.
Fit the large hex wrench onto the arbor nut. Turn clockwise
and remove the nut, taking care not to drag your knuckles
across the blade.
Note: The arbor nut has right-hand threads.
Remove the outer blade washer from the arbor and then
remove the blade. Make sure that inner blade washer and
both spacers are tight against arbor shoulder.
Replace with a new blade. Make sure the blade teeth are
pointing forward, toward incoming work.
Put the outer blade washer and arbor nut back on,
aligning with the flats on the arbor. Tighten the nut with a
clockwise turn.
Note: Use care not to cross thread arbor nut. Do not
overtighten.
Rotate the blade by hand to make sure it is turning freely.
Check the riving knife and adjust if needed (see next
procedure).
Lower the blade, insert the throat plate, then securely
tighten the throat plate screw.
