ASSEMBLY

WARNING:

Make sure the spindle lock button is not engaged before reconnecting saw to power source. Never engage spindle lock button when blade is rotat- ing.

INSTALLING / REPLACING THE BLADE

See Figure 13.

WARNING:

A 12 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 guards, while thicker blades will prevent the hex bolt from securing the blade on the spindle. Either of these situations could result in a serious accident and can cause serious personal injury.

Unplug the saw.

Raise saw arm.

Rotate lower blade guard up and loosen screw. Rotate

blade bolt cover up and back to expose the hex bolt.

Depress the spindle lock button and rotate the hex bolt

until the spindle locks.

Using the wrench provided, loosen and remove the hex

bolt.

NOTE: The hex bolt has left hand threads. Turn hex bolt
