Assembly (continued)

6.Remove the arbor screw, arbor washer, outer blade collar, and the blade.

NOTE: Pay attention to pieces removed, noting their position and direction they face (see illustration). Wipe the blade col- lars clean of any sawdust before installing the new blades.

CAUTION: To reduce the risk of cuts from extremely sharp teeth: Wear gloves when installing or removing sawblade.

See cautions in “Using Carbide Tipped Blades” section concerning inspection, use, and selection of carbide tipped and other sawblades.

7.Install the new 12" blade (see recom- mended accessory list). Make sure the rotation arrow on the blade matches the clockwise rotation arrow on the upper guard. The blade teeth should always point downward at the front of the saw.

8.Install the outer blade collar, blade washer and arbor screw. Press the arbor lock and turn the combination wrench or the 1/2" wrench counter clockwise to secure the blade. Tighten arbor screw using moderate force, but do not overtighten.

9.Lower the lower blade guard until the slot in cover plate rests all the way down on the cover plate stop screw. Tighten the screw with the Phillips end of the combination wrench.

DANGER: Never use saw without guard cover plate securely in place. It keeps the arbor screw from falling out if it accidentally loosens, and prevents the spin- ning blade from coming off the machine.

10.Be sure the arbor lock is released so the blade turns freely.

NOTE: The arbor lock can be damaged by improper use. If the arbor lock will not hold, lower the blade down on to a scrap piece of wood positioned against the fence. This will serve as an alternate lock- ing means.

WARNING: Make sure the collars are clean and properly arranged. After installing a new blade, make sure the blade clears the table slot at the 0° and 45° bevel positions. Lower the blade into the table slot and check for any contact with the base or turn table structure. If blade contacts table, seek authorized service.

If blade contacts insert, refer to “Align- ment“section for adjustment.
