Metal Cutting - Makita 4304 Manual De Instrucciones

Bevel cutting (Fig. 7 & 8)
With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right). Loosen the
bolt on the bottom of the tool. Move the base so that
the bolt is positioned in the center of the cross-
shaped slot in the base. Tilt the base until the desired
bevel angle is obtained. The edge of the motor hous-
ing indicates the bevel angle. (See Fig. 8.) Then
tighten the bolt to secure the base.
Flush cutting (Fig. 9)
Loosen the bolt on the bottom of the tool and move
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:
For internal cutouts without a lead-in cut from an
edge, pre-drill a starting hole more than 12 mm in
diameter. Insert the blade into this hole to start
your cut. (Fig. 10)
B) Plunge cutting:
Your 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. 11)
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. 12)
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 cut-
ting metal. Failure to do so will cause significant
blade wear. The underside of the workpiece can be
greased instead of using a coolant.
Plastic base plate (Fig. 13)
Use the plastic base plate when cutting decorative
veneers, plastics, etc. It protects sensitive surfaces
from damage. To replace the base plate, remove the
four screws.
Anti-splintering devise (Fig. 14)
For splinter-free cuts, the anti-splintering device can
be used. Fit it into the base from below.
Guide rule (optional accessory) (Fig. 15)
When cutting widths of under 150 mm repeatedly,
use of the guide rule (rip fence) will assure fast,
clean, straight cuts. To install it, loosen the bolt on the
front of the base. Slip in the guide rule and secure the
bolt.
Circular guide (optional accessory) (Fig. 16)
Use of the circular guide insures clean, smooth cut-
ting of circles (radius; under 200 mm. Insert the pin
through the center hole and secure it with the
threaded knob. Move the base of the tool forward
fully. Then install the circular guide on the base in the
same manner as the guide rule (rip fence).
Dust extraction (Fig. 17, 18 & 19)
The vacuum head is recommended to perform clean
cutting operations. Install the plastic cover on the tool
by fitting it into the notches in the tool.
To attach the vacuum head on the tool, insert the
hook of the vacuum head into the hole in the base.
The vacuum head can be installed on either left or
right side of the base. Then connect a Makita vac-
uum cleaner to the vacuum head.
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,
maintenance or adjustment should be carried out by
a Makita Authorized Service Center.
