INSTALLING THE BLADE

Remove the battery pack.

1.Remove any accumulated sawdust in the guards, around the arbor, and the telescoping guard spring. Check the telescoping guard to ensure that it is in working order.

2.Clean the inner blade flange,

retract the telescoping guard, and place a sharp blade on the arbor making sure that the teeth

point up at the front of the sawFig. 6 (Fig. 6).

3.Place the outer blade flange on the arbor with the flange toward the blade. Mate the flats with those on the arbor.

4.Replace the blade retaining bolt and finger tighten by turning counter- clockwise.

5.Push in the blade lock and rotate the blade arbor by hand until the lock engages the arbor. Tighten the blade retaining bolt with the blade wrench (C) Fig. 4 just enough to prevent blade slippage during normal cutting, and release the blade lock.

TELESCOPING GUARD

The telescoping guard (E) Fig. 7 is an important safety device. Each time you use the saw, see that the telescoping guard rotates freely and returns quickly and completely to its closed position. Frequently check the retracting spring (F) Fig. 8 to see that it is functional and free of debris. At least once a month, remove any accumulated sawdust, pitch, or other debris from the area around the hub (G) Fig. 7 of the telescoping guard, and add a few drops of light machine oil at each end of the hub. NEVER block or wedge the telescoping guard in the open position.

DO NOT use your saw if the telescoping guard is not in working order. If the telescoping guard movement is sluggish or binding exists, return the saw to your nearest AUTHORIZED PORTER-CABLE SERVICE STATION or PORTER-CABLE SERVICE CENTER for repair.
