ASSEMBLING BLADE AND BLADE GUARD TO MACHINE

1.DISCONNECT MACHINE FROM POWER SOURCE.

USE ONLY 10" BLADES WITH 5/8" ARBOR HOLES AND RATED FOR 5000 RPM OR HIGHER.

2.Assemble the inside (thick) arbor flange (A) Fig. 44, onto the arbor shaft with the recessed side of flange (A) facing out.

3.With the blade guard (B) Fig. 45, in the left hand, insert saw blade (C) into the blade guard (B) and onto the arbor shaft.

4.Assemble the outside (thin) blade flange (D) Fig. 45, with the recessed side of flange (D) facing in and arbor nut (E) onto the arbor shaft. NOTE: ARBOR NUT (E)

FIG. 45, HAS A LEFT HAND THREAD.

5.Lift cam (F) Fig. 46, and assemble blade guard (B) onto cutting-head assembly. NOTE: MAKE CERTAIN

TONGUE ON GUARD SEATS INTO GROOVE OF CUTTING-HEAD.

6.Pull back on blade guard (B) Fig. 47, so that it rotates to the rear, and tighten arbor nut (E) using two wrenches (G) supplied. Place the 7/8" box wrench around the arbor nut (E), and place the 7/8" open end wrench on the flat on the arbor, to hold the arbor while removing the arbor nut.

7.Rotate blade guard (B) Fig. 46, to the horizontal position and tighten clamp knob (H). IMPORTANT:

CLAMP KNOB (H) FIG. 46, MUST BE TIGHT AND BLADE GUARD SECURE DURING OPERATION.

NOTE: The lower retractable blade guard provides operator protection in an axial direction to the saw blade. Help eliminate potential hazards of the lower blade guard by using the following rules.

A)KEEP YOUR HANDS AWAY FROM THE GUARD. As the blade cuts, the guard will lift and leave part of the blade exposed.

B)SHUT OFF POWER BEFORE FREEING A JAMMED LOWER GUARD. The guard can get jammed in previous kerfs in table or fence. Always anticipate the path of the guard.

C)USE CAUTION when making bevel cuts to be sure the lower guard is never pinched towards the blade.

D)THE LOWER GUARD CAN JAM AGAINST THE FENCE DURING NARROW IN-RIPS. Should the guard jam against the fence, dis- connect the saw from power, wait for the blade to stop, then lift the blade guard and rest it on top of the fence.
