Then connect a Makita vacuum cleaner to the dust noz-
zle. (Fig. 14)
OPERATION
CAUTION:
• Always hold the base flush with the workpiece. Failure
to do so may cause blade breakage, resulting in a seri-
ous injury. (Fig. 15)
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 for-
ward along the previously marked cutting line.
NOTE:
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.
When cutting curves, advance the tool very slowly.
Bevel cutting (Fig. 16)
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before tilting the base.
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 bevel slot in the base. (Fig. 17)
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. 18)
Front flush cuts
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 tool base. (Fig. 19)
Cutouts
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole (Fig. 20):
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.
B) Plunge cutting (Fig. 21):
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.
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. 22)
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.
Rip fence set (optional accessory)
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
accessories.
1. Straight cuts (Fig. 23 & 24)
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 rectangu-
lar 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. 25 & 26)
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.
Guide rail adapter set (accessory) (Fig. 27)
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.
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. 28)
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. 29)
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.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before attempting to perform
inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
