Bevel cutting (Fig. 12 & 13)
Always unplug the tool before making any adjust-
With the base titled, you can make bevel cuts at any
angle between 0° and 45° (left or right). Loosen the
base securing lever and move the base so that the
dent mark in the motor housing is aligned with the
slot in the base. Tilt the base until the desired bevel
angle is obtained. The edge of the motor housing
indicates the bevel angle by graduations. Then
tighten the base securing lever to secure the base.
Flush cutting (Fig. 14)
Loosen the base securing lever and slide the base all
the way back. Then tighten the base securing lever to
secure the base.
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole (Fig. 15)
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.
B) Plunge cutting (Fig. 16)
Your need not bore a starting hole or make a
lead-in cut if you carefully do as follows:
Tilt the tool up on the front edge of the base, with
the blade point positioned just above the work-
piece surface.
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
As the blade pierces the workpiece, slowly lower
the base of the tool down onto the workpiece
Complete the cut in the normal manner.
Finishing edges (Fig. 17)
To trim edges or make slight dimensional adjust-
ments, 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. 18)
Use the plastic base plate when cutting decorative
veneers, plastics, etc. It protects sensitive or delicate
surfaces from damage. To replace the base plate,
remove the four screws.
Anti-splintering devise (Fig. 19)
To reduce the potential for workpiece surface splinter-
ing, the anti-splintering device can be used. Fit it into
the base from below so that it surrounds the sides of
the blade.
Guide rule (rip fence; optional accessory)
(Fig. 20)
When cutting width of under 150 mm repeatedly, use
of the guide rule 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. 21)
Use of the circular guide insures clean, smooth cut-
ting or circles under 200 mm in radius. Insert the pin
through the center hole and secure it with the
threaded knob. Move the base of the tool full forward.
Then install the circular guide on the base in the
same manner as the guide rule (rip fence).
Vacuum head (optional accessory)
(Fig. 22 & 23)
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 vacuum
cleaner to the vacuum head.


Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Cleaning the clamp on the blade holder
(Fig. 24)
If chips or foreign matter get into the clamp on the
blade holder, clean out the clamp after removing it
from the blade holder.
To remove the clamp, rotate the blade installing lever
(for 4304T) or knob (for 4305T) in the blade loosening
direction as far as it will go. Then remove the clamp
from the blade holder while rotating the clamp coun-
terclockwise. To install the clamp, first make sure that
the blade installing lever (for 4304T) or knob (for
4305T) has been rotated in the blade loosening
direction as far as possible. Insert the clamp into the
blade holder while rotating it clockwise one quarter to
one full turn. Grasp the clamp with your fingers so
that it will not turn, then rotate the blade installing
lever or know in the blade tightening direction so that
the clamp will go into the blade holder.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
a Makita Authorized Service Center.
