ANTI-SPLINTER
INSERT
PLUNGE CUTTING
See Figure 12.
WARNING:
To avoid loss of control, broken blades, or damage 
to the material being cut, always use extreme 
caution when making plunge cuts. We do not 
recommend plunge cutting on materials other 
than wood.
n
Mark the line of cut clearly on the workpiece.
n
Set the cutting angle at 0°.
n
Tilt the saw forward so that it rests on the front edge
of the base and blade will not come in contact with the 
workpiece when the saw is turned on.
n
Make sure the blade is inside the area to be cut.
n
Using high speed, start your saw and slowly lower the
blade into the workpiece until the blade cuts through the 
wood.
n
Continue lowering the blade into the workpiece until the
base rests flat on the work surface, then move the saw 
forward to complete the opening.
n
Use only the 7 teeth per inch blade for this type of cut.
SPLINTER-FREE CUTTING
See Figure 13.
This saw has an anti-splinter insert to permit splinter-free 
cutting. It is especially useful when cutting plywood. This 
feature should only be used when making straight cuts or 
circle cuts. It is not for bevel cutting or plunge cutting.
NOTE:
The non-orbital setting also helps reduce splintering
when cutting plywood.
n
Remove the battery pack.
n
Set the cutting angle at 0°.
n
Attach the anti-splinter insert in the front of the base as
shown. Make sure it snaps securely into place.
n
Replace the battery pack.
