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 Figures 16 and 17.

Make sure the bevel locking lever is securely pushed to the left. Raise the blade arbor to its full height by turning the blade adjusting handle clockwise.

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 left hand threads.

Check all clearances for free blade rotation.

See To Set the Scale to the Blade in the Operation Section. In cutting operations, the scale will be set to the side of the blade where the cut will be measured and made.

TO INSTALL BLADE GUARD ASSEMBLY

Move the bevel locking lever to the right for angle mode. Slowly turn the blade adjustment handle to put the blade at 30˚. The handle will "pop out" slightly as it engages the clutch.

Holding the blade adjusting handle with one hand, use the other hand to push the bevel locking lever firmly to the left to lock the bevel angle.

Raise 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 19. 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 29.

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.
