Metal Cutting - Makita BJV140 Manual De Instrucciones

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:
014142
For internal cutouts without a lead-in cut from an
•
edge, pre-drill a starting hole 12 mm (1/2") or more
in diameter. Insert the blade into this hole to start
your cut.
B) Plunge cutting:
014143
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.

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
When repeatedly cutting widths of 160 mm (6-5/16") 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.
