changing/installing the blade.
1. Install a 7-1/4 in. blade with a 5/8
in. arbor making sure the rotation
arrow on the blade matches the
clockwise rotation arrow on the
upper guard, and the blade teeth
are pointing downward.
2. Place the arbor collar (6) against
the blade and on the arbor. Thread
the arbor bolt (4) on the arbor. in a
counterclockwise direction. (Fig. M)
IMPORTANT: Make sure the flats
of the blade collars are engaged
with the flats on the arbor shaft.
Also, the flat-side of the arbor collar
must be placed against the blade.

it in firmly while turning the blade
counterclockwise. When it engages,
continue to press the arbor lock

its original position until the slot in
the cover plate engages with the

guard must be raised to the upright
position to access the cover plate
screw.
