• 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)
8
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.
Dust extraction
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. (Fig. 16 & 17)
The dust nozzle can be installed on either left or right
side of the base.
Then connect a Makita vacuum cleaner to the dust noz-
zle. (Fig. 18)
CAUTION:
• If you try to remove the dust nozzle forcibly, the hook of
the dust nozzle can be diminished and removed unin-
tentionally during operation.
Rip fence set (optional accessory)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing accessories.
1) Straight cuts (Fig. 19 & 20)
When repeatedly cutting widths of 160 mm or less,
use of the rip fence will assure fast, clean, straight
cuts. To install, insert the rip fence into the rectangular
hole on the side of the tool base with the fence guide
facing down. Slide the rip fence to the desired cutting
width position, then tighten the bolt to secure it.
2) Circular cuts (Fig. 21 & 22)
When cutting circles or arcs of 170 mm or less in
radius, install the rip fence as follows.
Insert the rip fence into the rectangular hole on the
side of the base with the fence guide facing up. Insert
the circular guide pin through either of the two holes
on the fence guide. Screw the threaded knob onto the
pin to secure the pin.
Now slide the rip fence to the desired cutting radius,
and tighten the bolt to secure it in place. Then move
the base all the way forward.
NOTE:
• Always use blades No. B-17, B-18, B-26 or B-27
when cutting circles or arcs.
