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
007494
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.
Rip fence set (optional accessory)
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before installing or
removing accessories.
