To remove the blade, follow the installation procedure in
reverse.
NOTE:
• Occasionally lubricate the roller.
Hex wrench storage (Fig. 6)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
First, insert the hex wrench into the hole. Then push it into
the hook until it locked.
Dust cover (Fig. 7)
CAUTION:
• Always wear safety goggles even when operating the
tool with the dust cover lowered.
Lower the dust cover to prevent chips from flying.
However, when making bevel cuts, raise it all the way.
OPERATION
CAUTION:
• Always hold the base flush with the workpiece. Failure
to do so may cause blade breakage, resulting in a
serious injury.
• Advance the tool very slowly when cutting curves or
scrolling. Forcing the tool may cause a slanted cutting
surface and blade breakage. (Fig. 8)
Turn the tool on without the blade making any contact and
wait until the blade attains full speed. Then rest the base
flat on the workpiece and gently move the tool forward
along the previously marked cutting line.
Bevel cutting (Fig. 9)
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before tilting the base.
• Raise the dust cover all the way before making bevel
cuts. (Fig. 10)
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 cross-shaped slot in the base. (Fig. 11)
Tilt the base until the desired bevel angle is obtained. The
edge of the motor housing indicates the bevel angle by
graduations. Then tighten the bolt to secure the base.
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)
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.
Rip fence (optional accessory)
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before installing or
removing accessories.
1. Straight cuts (Fig. 17)
When repeatedly cutting widths of 160 mm or less,
use of the rip fence will assure fast, clean, straight
cuts. (Fig. 18)
To install, insert the rip fence into the rectangular hole
on the side of the 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
When cutting circles or arcs of 170 mm or less in
radius, install the rip fence as follows. (Fig. 19)
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. (Fig. 20)
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.
