Operation - Makita 4334D Instruction Manual

Vacuum head (optional accessory) (Fig. 9 & 10)
The vacuum head is recommended to perform clean cut-
ting operations. Install the plastic cover on the tool by fit-
ting 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 vac-
uum head.
Installing or removing the saw blade
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the blade.
• Always clean off the blade and blade holder before
installing the blade. Chips or foreign matter on them
may cause insufficient securing of the blade, possibly
resulting in blade breakage or serious injury.
Installation
1. Push the blade installing lever in the (1) direction to
release it. (Fig. 11)
2. Pull the blade installing lever in the (2) direction until
it stops with a little click. If you have difficulty pulling
it out, try to do so while moving it back and forth in
the (3) direction.
3. Rotate the blade installing lever in the (4) direction
until the clamp protrudes 5 – 7 mm from the blade
holder. (Fig. 12)
CAUTION:
If you rotate the blade installing lever excessively, the
clamp will also rotate and finally come off. In this
case, re-install it properly as lately described in
"Installing clamp".
4. With the blade teeth facing forward, insert the blade
into the blade holder as far as it will go. Make sure
that the back edge of the blade fits properly into the
groove of the roller. (Fig. 13)
5. With the blade held against the blade holder, rotate
the blade installing lever in the (5) direction until it
stops. (Fig. 14)
6. With the blade installing lever held in this position,
push it in the (6) direction. Then rotate the blade
installing lever to its original position. (Fig. 15)
Removal
1. Push the blade installing lever in the (1) direction to
release it. (Fig. 16)
2. Pull the blade installing lever in the (2) direction until
it stops with a little click. If you have difficulty pulling
it out, try to do so while moving it back and forth in
the (3) direction.
3. Rotate the blade installing lever in the (4) direction
and remove the blade. (Fig. 17)
4. Rotate the blade installing lever in the (5) direction
until it stops. (Fig. 18)
5. With the blade installing lever held in this position,
push it in the (6) direction. Then rotate the blade
installing lever to its original position. (Fig. 19)

OPERATION

Cutting operation
CAUTION:
• Always hold the tool with the base flush with the work-
piece. Failure to do so may cause a slanted cutting sur-
face and blade breakage.
• Advance the tool very slowly when cutting curves or
scrolling. Forcing the tool may cause a slanted cutting
surface and blade breakage.
Turn the tool on without the blade making any contact.
Rest the base flat on the workpiece and gently move the
tool forward along the previously marked cutting line.
(Fig. 20)
Bevel cutting (Fig. 21 & 22)
CAUTION:
Always remove the battery from the tool before making
any adjustments.
With the base tilted, 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. The tighten the base securing lever to
secure the base.
NOTE:
Always remove the plastic cover (chip shield) from the
tool when you make bevel cuts using an optional guide
rule (rip fence) or circular guide.
Flush cutting (Fig. 23)
Loosen th base securing lever and slide the base all the
way back. Then tighten the base securing lever to secure
the base.
Cutouts (Fig. 24 & 25)
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 and hold the
tool firmly against the workpiece to start your cut.
B) Plunge cutting:
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 slices into the workpiece, slowly
lower the base of the tool down onto the work-
piece surface.
4. Complete the cut in the normal manner.
Finishing edges (Fig. 26)
To trim edges or make slight dimensional adjustments,
run the blade lightly along the cut edges.
