3. While holding the blade lock
engaged, use the blade wrench
to loosen the blade retaining bolt
by rotating clockwise. NOTE:
The blade bolt has a left-hand
thread.
4. Remove the blade retaining bolt,
release the blade lock, and
remove the outer blade flange.
5. Retract telescoping guard and
remove blade.
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 saw
(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.
