ASSEMBLY

ATTACHING THE BLADE

See Figure 2.

WARNING:

A 6-1/2 in. blade is the maximum blade capacity of the saw. Never use a blade that is too thick to allow outer blade washer to engage with the flats on the spindle. Larger blades will come in contact with the blade guard, while thicker blades will prevent blade screw from securing blade on spindle. Either of these situations could result in a serious accident.

nRemove the battery pack from the saw.

nRemove the hex key from the storage area.

nDepress the spindle lock button and remove the blade screw and outer blade washer.

NOTE: Turn the blade screw clockwise to remove.
