Cutouts

Cutouts can be made with either of two methods A or B.

A) Boring a starting hole

002760

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

002761

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

002767

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.

Dust extraction

002771

Clean cutting operations can be performed by connecting this tool to a Makita

vacuum cleaner. Insert the hose of the vacuum cleaner into the hole at the

rear of the tool. Lower the dust cover before operation.

NOTE:

•

Dust extraction cannot be performed when making bevel cuts.
