BASE INSERT

Two base inserts, like the one shown in Fig. 3, are available to reduce splintering the top fibers of plywood and other splinter-prone materials. One insert has a short center slot for use with tapered tooth blades up to 1/4" wide. The other insert has a long center slot for use with tapered tooth blades that are 3/8" wide. DO NOT USE BASE INSERTS WITH ANY TYPE BLADES OTHER THAN THOSE DESCRIBED. TO DO SO, MAY RESULT IN BLADE BREAKAGE OR DAMAGE TO THE SAW.

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.

When cutting plywood with the base insert installed in the saw, it is not necessary for the good or finished side of the material to be down as would be the practice with an ordinary jig saw. The small teeth of the blade and speed of the saw in conjunction with the base insert will prevent splintering or chipping of the top surface.
