Front flush cuts
Fig.20
Loosen the bolt on the back of the base with the hex
wrench and slide the base all the way back. Then tighten
the bolt to secure the base.
Cutouts
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole:
Fig.21
For internal cutouts without a lead-in cut from an
edge, pre-drill a starting hole 12 mm or more in
diameter. Insert the blade into this hole to start your
cut.
B) Plunge cutting:
Fig.22
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
Fig.23
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.
Replacing carbon brushes

Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.
