Cutouts
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole:
1
For internal cutouts without a lead-in cut from an
edge, pre-drill a starting hole 12 mm (1/2") or more
in diameter. Insert the blade into this hole to start
your cut.
B) Plunge cutting:
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
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.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.

If chips or foreign matter get into the clamp on the blade
holder, clean out the clamp after removing it from the
