Bevel cutting
CAUTION:
• Always be sure that the tool is switched off and
unplugged before tilting the tool base.
With the tool 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 & 11)
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 tool base with the hex
wrench, then move the tool base all the way back. Then
tighten the bolt to secure the tool 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 diameter. 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.
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 nozzle. To remove the dust nozzle, follow the
installing procedure in reverse. (Fig. 18)
CAUTION:
If you try to remove the dust nozzle forcibly, the hook of
the dust nozzle can be diminished and removed uninten-
tionally during operation.
Rip fence set (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 tool 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 tool base all the way forward.
NOTE:
Always use blades No. B-17, B-18, B-26 or B-27 when
cutting circles or arcs.
Guide rail adapter set (accessory)
When cutting parallel and uniform width or cutting
straight, the use of the guide rail and the guide rail
adapter will assure the production of fast and clean cuts.
(Fig. 23)
To install the guide rail adapter, insert the rule bar into the
square hole of the base as far as it goes. Secure the bolt
with the hex wrench securely. (Fig. 24)
Install the guide rail adapter on the rail of the guide rail.
Insert the rule bar into the square hole of the guide rail
adapter. Put the base to the side of the guide rail, and
secure the bolt securely. (Fig. 25)
CAUTION:
Always use blades No. B-8, B-13, B-16, B-17 or 58 when
using the guide rail and the guide rail adapter.
Cover plate (Fig. 26)
Use the cover plate when cutting decorative veneers,
plastics, etc. It protects sensitive or delicate surfaces
from damage. Fit it on the back of the tool base.
Anti-splintering device (Fig. 27)
For splinter-free cuts, the anti-splintering device can be
used. To install the anti-splintering device, move the tool
base all the way forward and fit it from the back of tool
base. When you use the cover plate, install the anti-splin-
tering device onto the cover plate.
CAUTION:
The anti-splintering device cannot be used when making
bevel cuts.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
