To start the miter saw, depress the switch trigger (A) Fig. 14. To stop the miter saw, release the switch trigger.

This saw is equipped with an automatic electric blade brake. As soon as the switch trigger (A) Fig. 14 is released, the electric brake activates and stops the blade in seconds.

A TURNING SAW BLADE CAN BE DANGEROUS. AFTER COMPLETING THE CUT, RELEASE THE SWITCH TRIGGER (A) FIG. 14 TO ACTIVATE THE BLADE BRAKE. KEEP THE CUTTINGHEAD DOWN UNTIL THE BLADE HAS COME TO A COMPLETE STOP.

THE TORQUE DEVELOPED DURING BRAKING MAY LOOSEN THE ARBOR SCREW. CHECK THE ARBOR SCREW PERIODICALLY AND TIGHTEN IF NECESSARY.

LOCKING THE SWITCH IN THE “OFF” POSITION

IMPORTANT: When the miter saw is not in use, lock the switch in the “OFF” position, using a padlock (B) Fig. 15 with a 3/16" diameter shackle to prevent unauthorized use of the saw.

POINTER AND SCALE

A pointer (A) Fig. 16 is supplied to indicate the actual angle of cut. Each line on the scale (B) represents 1 degree. When the pointer is moved from one line to the next on the scale, the angle of cut is changed by 1 degree.

ROTATING THE TABLE FOR MITER CUTTING

Your miter saw will cut any angle from a straight 90° cut to 47° right and left. Loosen the lock handle (A) Fig. 17 one or two turns, depress the index lever (B), and move the control arm to the desired angle. TIGHTEN THE LOCK HANDLE (A). The miter saw is equipped with positive stops at the 0°, 15.5, 22.5°, 31.62°, and 45° right and left positions. Loosen the lock handle (A) Fig. 17, and move the control arm until the bottom of the index lever (B) engages into one of the positive stops (C) Fig. 17. TIGHTEN THE LOCK HANDLE (A) Fig. 17. To disengage the positive stop, depress the index lever (B).

Additionally, a triangle indicator and positive stop are provided on the miter scale at the 31.62° right and left miter positions (D) Fig.18 for cutting crown moulding. (Refer to the “CUTTING CROWN MOULDING” section of this manual).

IMPORTANT: Always tighten the lock handle (A) Fig. 17 before cutting.
