blade and the arrow on the upper guard are pointing in
the same direction.
NOTE: The saw teeth point upward at the front of the saw
as shown.
 Fit the saw blade inside the lower blade guard and onto
the spindle.
 Replace “D” washer.
 Replace spring washer with cupped side against “D”
washer.
 Depress spindle lock button and replace blade screw.
 Tighten blade screw securely by turning it clockwise with
the blade wrench.
NOTE: Never use a blade that is too thick to allow the
“D” washer to engage with the flat on the spindle.
REMOVING BLADE
See Figures 2 - 4, pages 15 and 16.
 Unplug the saw.

Depress and hold spindle lock button.
 Remove blade screw by turning it counterclockwise with
the blade wrench, while keeping the spindle lock button
depressed.

WARNING:
Do not connect to power supply until assembly is
complete. Failure to comply could result in accidental
starting and possible serious personal injury.
WARNING:
A 7-1/4 in. blade is the maximum blade capacity of the
saw. Also, never use a blade that is too thick to allow
outer blade washer to engage with the flat on the spindle.
Larger blades will come in contact with the blade guards,
while thicker blades will prevent blade screw from se-
curing blade on spindle. Either of these situations could
result in a serious accident.
CAUTION:
To prevent damage to the spindle or spindle lock, always
allow motor to come to a complete stop before engaging
spindle lock.
