CHIP BLOWER
This saw is equipped with a chip blower to keep the cutting area free of
chips. This blower may be switched “ON” or “OFF” by moving lever (A), Fig.
8, to the “OPEN” position (blower “ON”) or the “CLOSED” position (blower
“OFF”).
PLUNGE CUTTING
When cutting into a
wall avoid contact with all exposed
metal on the tool to prevent
electrical shock hazard resulting
from accidentally cutting into a live
wire. HOLD SAW AS ILLUSTRATED
IN FIG. 9.
One of the distinctive and important
features of the Porter-Cable bayonet
saw is the ability to start the cut (in
wood only) within an area without
making drilled holes first. This is
especially important when making
cutouts for electrical outlets in finished
walls, openings in cabinet tops for sinks and openings for plumbing fixtures.
NOTE: When plunge cutting, it is recommended the orbit knob be set
to position “3”.
