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 / 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

clockwise to loosen.

Remove the washer, outer blade washer (or laser guide),

and the blade. Do not remove the inner blade washer.

Wipe a drop of oil onto the inner blade washer and the

outer blade washer (or laser guide) 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.

Fit saw blade inside lower blade guard and onto spindle. The blade teeth point downward at the front of saw as shown in figure 13.

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.

Replace outer blade washer (or laser guide). The double “D” flats on the blade washers align with the flats on the spindle.

Depress spindle lock button and replace the washer and hex bolt.

NOTE: The hex bolt has left hand threads. Turn blade bolt counterclockwise to tighten.

Tighten hex bolt securely.

Replace the lower blade guard and blade bolt cover.

Retighten the screw securely.
