Operation; Metal Cutting; Bevel Cutting; Dust Extraction - Makita 4351T Instruction Manual

Fig.4
Keeping that situation, insert the saw blade into the
blade clamp as far as the two protrusions of the blade
can not be seen.
Fig.5
Return the tool opener to its original position.
After installing, always make sure that the blade is
securely held in place by trying to pull it out.
CAUTION:
Do not open the tool opener excessively, or it may
•
cause tool damage.
To remove the blade, open the tool opener to the
position shown in the figure. Pull the saw blade out
toward the base.
Fig.6
NOTE:
Occasionally lubricate the roller.

Hex wrench storage
Fig.7
When not in use, the hex wrench can be conveniently
stored.

OPERATION

CAUTION:
Hold the tool firmly with one hand on the switch
•
handle and the other hand on the front grip when
performing the tool.
Always hold the base flush with the workpiece.
•
Failure to do so may cause blade breakage,
resulting in a serious injury.
Fig.8
Turn the tool on and wait until the blade attains full speed.
Then rest the tool base flat on the workpiece and gently
move the tool forward along the previously marked cutting
line. When cutting curves, advance the tool very slowly.

Bevel cutting

Fig.9
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before tilting the base.
With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right).
Loosen the bolt on the back of the base with the hex
wrench. Move the base so that the bolt is positioned in
the center of the bevel slot in the base.
Fig.10
Tilt the base until the desired bevel angle is obtained.
The V-notch of the gear housing indicates the bevel
angle by graduations. Then tighten the bolt firmly to
secure the base.
Fig.11
Front flush cuts
Fig.12
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.13
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.14
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.15
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

Fig.16
Fig.17
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.
Fig.18
CAUTION:
If you try to remove the dust nozzle forcibly, the
•
hook of the dust nozzle can be diminished and
removed unintentionally during operation.
