tool, press the lock-off lever and pull the switch trigger
with the lock-off lever being pressed.
NOTE:
• Use a cotton stick to wipe the dirt off the lens of lamp.
Be careful not to scratch the lens of lamp, or it may
lower the illumination.
• Do not use gasoline, thinner or the like to clean the lens
of lamp. Using such substances will damage the lens.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Removing or installing blade (Fig. 7)
CAUTION:
• Be sure the blade is installed with teeth pointing up at
the front of the tool.
• Use only the Makita wrench to install or remove the
blade.
To remove the blade, press the shaft lock so that the
blade cannot revolve and use the wrench to loosen the
hex bolt counterclockwise. Then remove the hex bolt,
outer flange and blade.
To install the blade, follow the removal procedure in
reverse. BE SURE TO TIGHTEN THE HEX BOLT
CLOCKWISE SECURELY. (Fig. 8)
When changing blade, make sure to also clean upper and
lower blade guards of accumulated chips and particles.
Such efforts do not, however, replace the need to check
lower guard operation before each use.
Hex wrench storage (Fig. 9)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.

OPERATION

CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. If you can see the red part on the upper
side of the button, it is not locked completely. Insert it
fully until the red part cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to you or
someone around you.
• Be sure to move the tool forward in a straight line
gently. Forcing or twisting the tool will result in
overheating the motor and dangerous kickback,
possibly causing severe injury.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
• Never twist or force the tool in the cut. This may cause
motor overload and/or a dangerous kickback, resulting
in serious injury to the operator.
• Always wear eye protection or goggle before operation.
(Fig. 10)
Hold the tool firmly. The tool is provided with both a front
grip and rear handle. Use both to best grasp the tool. If
both hands are holding the tool, they cannot be cut by the
blade. Set the base on the workpiece to be cut without the
blade making any contact. Then turn the tool on and wait
until the blade attains full speed. Now simply move the
tool forward over the workpiece surface, keeping it flat
and advancing smoothly until the cutting is completed.
To get clean cuts, keep your cutting line straight and your
speed of advance uniform. If the cut fails to properly follow
your intended cut line, do not attempt to turn or force the
tool back to the cut line. Doing so may bind the blade and
lead to dangerous kickback and possible serious injury.
Release switch, wait for blade to stop and then withdraw
tool. Realign tool on new cut line, and start cut again.
Attempt to avoid positioning which exposes operator to
chips and particles being ejected from the tool. Use eye
protection to help avoid injury.
The sight grooves in the base makes it easy to check the
distance between the front edge of the blade and the
workpiece whenever the blade is set to the maximum
depth of cut. (Fig. 11)
CAUTION:
• Do not use a deformed or cracked blade. Replace it
with a new one.
• Do not stack materials when cutting them.
• Do not cut hardened steel, stainless steel, wood,
plastics, concrete, tile, etc. Cut only mild steel and
aluminum.
• Do not touch the blade, workpiece or cutting chips with
your bare hand immediately after cutting, they may be
extremely hot and could burn your skin.
• Always use the blades appropriate for your job.
The use of inappropriate blades may cause a poor
cutting performance and/or present a risk of personal
injury.
Rip fence (guide rule) (Accessory)
(Fig. 12)
The handy rip fence allows you to do extra-accurate
straight cuts. Simply slide the rip fence up snugly against
the side of the workpiece and secure it in position with the
screw on the front of the base. It also makes repeated
cuts of uniform width possible.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Inspecting blade
• Check the blade carefully for cracks or damage before
and after each use. Replace a cracked or damaged
blade immediately.
• Continuing to use a dull blade may cause a dangerous
kickback and/or motor overload.
Replace with a new blade as soon as it no longer cuts
effectively.
• Blades for metal cutter cannot be re-sharpened.
Replacing carbon brushes (Fig. 13)
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep the
carbon brushes clean and free to slip in the holders.
