008037
You need not bore a starting hole or make a lead-in
cut if you carefully do as follows.
(1) Tilt the tool up on the front edge of the base
with the blade point positioned just above the
workpiece surface.
(2) Apply pressure to the tool so that the front
edge of the base will not move when you
switch on the tool and gently lower the back
end of the tool slowly.
(3) As the blade pierces the workpiece, slowly
lower the base of the tool down onto the
workpiece surface.
(4) Complete the cut in the normal manner.
Finishing edges
008038
To trim edges or make dimensional adjustments, run the
blade lightly along the cut edges.

Metal cutting

Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause significant blade wear.
The underside of the workpiece can be greased instead
of using a coolant.

1. Straight cuts
When repeatedly cutting widths of 160 mm (6-5/16") or
less, use of the rip fence will assure fast, clean, straight
cuts. To install, insert the rip fence into the rectangular
hole on the side of the tool base with the fence guide
installing or removing
facing down. Slide the rip fence to the desired cutting
width position, then tighten the bolt to secure it.
