ASSEMBLY

BLADE AND GUARD ASSEMBLY

WARNING:

Do not connect to power supply until assembly is complete. Failure to comply could result in accidental starting and possible serious injury.

TO CHECK SAW BLADE INSTALLATION

￿To check the saw blade, first remove the screw holding the throat plate in place. Remove the throat plate. See Figure 14.

￿Make sure the bevel locking lever is locked. Raise the blade arbor to its full height by turning the blade adjusting handle counterclockwise.

￿Using the smaller hex wrench, insert the flat open end into the flats on the arbor shaft as shown. Insert the larger hex wrench over the hex nut, and, holding both wrenches firmly, pull the larger wrench forward to the front of the machine to loosen and push to tighten. Make sure the blade nut is securely tightened. Do not overtighten.

Note: Arbor shaft has right-hand threads.

￿Check all clearances for free blade rotation.

TO INSTALL BLADE GUARD ASSEMBLY

￿Lower the blade by turning the blade adjustment handle clockwise.

￿Using the small hex wrench, install the blade guard assembly by loosening the two attachment hex nuts enough to slide the riving knife down between the shims. See Figure 16. Partially retighten the two attachment nuts. Check the blade and riving knife alignment. Make sure riving knife clears blade by 1/8 in. See Figure 24.

￿Correctly align the blade and riving knife as shown, repeating above step as needed. Tighten attachment nuts securely. If riving knife is not positioned correctly with blade up, it could contact saw table when blade is lowered and restrict blade elevation.
