fully retracted into the blade cover, remove the saw
blade. (Fig. 16)
2. Mounting the saw blade
(1) Thoroughly remove any sawdust which has
accumulated on the spindle, bolt and washers.
(2) For mounting saw blade, the concave sides of both
washers (A) and (B) must be fitted to the saw blade
sides. Mount the saw blade on the spindle, and
finally affix washer (B) (See Fig. 17)
