Fig. 7
BASE INSERT
A base insert #48367 (A) Fig. 7, is furnished with your bayonet saw.
This base insert will reduce splintering top fibers of plywood.
To install insert, remove saw blade from Bayonet Saw and locate
insert in the throat of the saw base with the slot forward and the
beveled side of the slot up. Install appropriate blade as outlined in
section INSTALLING THE BLADE with the blade body in the slot of
the insert.
PLUNGE CUTTING
WARNING: 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. 8.
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 cut-outs 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”.
