Operation - Makita BJV140 Bedienungsanleitung

OPERATION

CAUTION:
Always hold the base flush with the workpiece.
•
Failure to do so may cause blade breakage,
resulting in a serious injury.
Fig.14
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.
NOTE:
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
When cutting curves, advance the tool very slowly.
Bevel cutting
Fig.15
CAUTION:
Always be sure that the tool is switched off and the
•
battery 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.16
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.17
Front flush cuts
Fig.18
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.19
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.20
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.21
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
•
battery cartridge is removed before installing or
removing accessories.
1. Straight cuts
Fig.22
Fig.23
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.24
Fig.25
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.26
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.
