ASSEMBLY
WARNING:
Your tool should never be connected to power supply
when you are assembling parts, making adjustments,
cleaning, performing maintenance, or when not in
use. Disconnecting your tool will prevent accidental
starting that could cause serious injury.
WARNING:
7-1/4 in. (184 mm) blade is the maximum blade
capacity of your 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 securing blade on
spindle. Either of these situations could result in a
serious accident.
ATTACHING BLADE
See Figures 2 and 3.
Follow these directions to attach the blade.
■ UNPLUG YOUR CIRCULAR SAW.
WARNING:
Failure to unplug the tool could result in accidental
starting causing serious injury.
■ Remove wrench from storage area.
CAUTION:
To prevent damage to the spindle or spindle lock,
always allow motor to come to a complete stop before
engaging spindle lock.
■ Depress spindle lock button.
■ Remove blade screw by turning it counterclockwise
with the wrench.
■ Remove spring washer and outer washer
(“D” washer).
■ Wipe a drop of oil onto inner washer and outer
washer ("D" washer) where they contact blade.
WARNING:
If inner washer has been removed, replace it before
placing blade on spindle. Failure to do so could cause
an accident since blade will not tighten properly.
