Operation - Makita 4334D Betriebsanleitung

Speed adjusting dial (Fig. 4)
The tool speed can be adjusted and maintained between
500 and 2,800 strokes per minute by turning the adjust-
ing dial. The dial is marked 1 (lowest speed) to 5 (full
speed).
Refer to the table below to select the proper speed for the
workpiece to be cut. However, the appropriate speed
may differ with the type or thickness of the workpiece. In
general, higher speeds will allow you to cut workpieces
faster but the service life of the blade will be reduced.
Workpiece to be cut
Wood
Mild steel
Stainless steel
Aluminum
Plastics
CAUTION:
Adjust the speed adjusting dial only within the range of
numbers 1 through 5. Do not force the dial beyond this
range or damage to the tool may result.
Anti-splintering device (Fig. 5)
To reduce the potential for workpiece surface splintering,
the anti-splintering device can be used. Fit it into the
base from below so that it surrounds the sides of the
blade.
Plastic base plate (optional accessory) (Fig. 6)
Use the plastic base plate when cutting decorative
veneers, plastics, etc. It protects sensitive or delicate sur-
faces from damage. To replace the base plate, remove
the four screws.
Guide rule (rip fence; optional accessory) (Fig. 7)
When cutting widths 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. 8)
Use of the circular guide insures clean, smooth cutting 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.
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.
