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 rotating.

INSTALLING THE BLADE

See Figure 12.

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

Depress and hold 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 clockwise to loosen.

Remove the laser guide or outer blade washer, and the blade. Do not remove the inner blade washer.

Wipe a drop of oil onto the inner blade washer and the laser guide or outer blade washer where they contact the blade.

WARNING:

If inner blade 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.

CAUTION:

Always install the blade with the blade teeth and the arrow printed on the side of the blade pointing down at the front of the saw. The direction of blade rotation is also stamped with an arrow on the upper blade guard.
