Metal Cutting; Dust Extraction - Makita 4351T Instruction Manual

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:
008036
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:
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.

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.

The dust nozzle (accessory) is recommended to
perform clean cutting operations.
To attach the dust nozzle on the tool, insert the hook of
dust nozzle into the hole in the base.
The dust nozzle can be installed on either left or right
side of the base.
Then connect a Makita vacuum cleaner to the dust
nozzle.
