With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right).
Fig.8
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.9
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.10
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.11
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.12
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.13
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.14
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.
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
unplugged before installing or removing
accessories.
1. Straight
cuts
Fig.15
When repeatedly cutting widths of 160 mm or less,
use of the rip fence will assure fast, clean, straight
cuts.
Fig.16
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
Fig.17
Fig.18
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.
Anti-splintering device for steel base
(optional accessory)
Fig.19
For splinter-free cuts, the anti-splintering device can be
used. To install the anti-splintering device, move the base
all the way forward and insert it between the two
protrusions of the base.
NOTE:
•
The anti-splintering device cannot be used when
making bevel cuts.
