Operation - Makita 4351TJ Instruction Manual

Lighting up the lamps
For 4351FCT only
CAUTION:
• Do not look in the light or see the source of light
directly.
To turn on the lamp, pull the trigger. Release the trigger
to turn it off.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing saw blade (Fig. 4, 5 & 6)
CAUTION:
• Always clean out all chips or foreign matter adhering to
the blade and/or blade holder. Failure to do so may
cause insufficient tightening of the blade, resulting in a
serious personal injury.
• Do not touch the blade or the workpiece immediately
after operation; they may be extremely hot and could
burn your skin.
• Tighten the saw blade securely. Failure to do so may
cause a serious injury.
• When you remove the saw blade, be careful not to hurt
your fingers with the top of the blade or the tips of work-
piece.
To install the blade, open the tool opener to the position
shown in the figure. (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 seri-
ous injury.
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 cut-
ting line. When cutting curves, advance the tool very
slowly. (Fig. 8)
Bevel cutting
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). (Fig. 9)
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:
For internal cutouts without a lead-in cut from an
edge, pre-drill a starting hole 12 mm or more in diam-
eter. Insert the blade into this hole to start your cut.
(Fig. 13)
B) Plunge cutting:
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 work-
piece surface. (Fig. 14)
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 sur-
face.
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.
