SAFETY INSTRUCTIONS
WARNING! When using electric tools, basic safety
precautions, including the following, should always
be followed to reduce the risk of fire, electric shock
and personal injury. Read all these instructions
before operating this product and save these
instructions.
WARNING:
The vibration emission during actual use of the
power tool can differ from the declared emission
value depending on the ways in which the tool is
used.
Be sure to identify safety measures to protect the
operator that are based on an estimation of
exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it
is running idle in addition to the trigger time).
For safe operations:
1.
Keep work area clean.
Cluttered areas and benches invite injuries.
Consider work area environment.
Do not expose power tools to rain. Do not use
power tools in damp or wet locations. Keep work
area well lit. Do not use power tools where there is
risk to cause fire or explosion.

ADDITIONAL SAFETY RULES
FOR TOOL
Keep cutting tools sharp and clean for better and
safer performance. Follow instructions for
lubrication and changing accessories. Inspect tool
cord periodically and if damaged have it repaired
by an authorized service facility. Inspect extension
cords periodically and replace, if damaged. Keep
handles dry, clean and free from oil and grease.
15. Disconnect tools.
1.
Always use safety glasses, dust mask and ear
protector.
2.
Use only Makita genuine carbide-tipped saw
blade 305 mm in diameter for metal cutting.
Never use abrasive cut-off wheel or other type
of saw blades.
3.
4.
Check the blade carefully for cracks or
damage before operation. Replace cracked or
damaged blade immediately.
Never secure the safety cover (safety guard).
Always be sure that the safety cover moves
smoothly before operation. Any irregular
operation of the safety cover should be
corrected immediately. Do not use the saw
without guards in position.
When not in use, before servicing and when
changing accessories such as blades, bits and
cutters.
16. Remove adjusting keys and wrenches.
Form the habit of checking to see that keys and
adjusting wrenches are removed from the tool
before turning it on.
17. Avoid unintentional starting.
5.
6.
Be sure shaft lock is released before the
switch is turned on.
Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced blade.
Do not carry a plugged-in tool with a finger on the
switch. Ensure switch is off when plugging in.
18. Use outdoor extension leads.
When tool is used outdoors, use only extension
cords intended for outdoor use.
19. Stay alert.
7.
Keep your hands and body away from rotating
blade.
Always secure the workpiece with the vise.
Make sure the blade is not contacting the
workpiece before the switch is turned on.
Watch what you are doing. Use common sense.
Do not operate tool when you are tired.
20. Check damaged parts.
8.
9.
Before further use of the tool, a guard or other part
that is damaged should be carefully checked to
determine that it will operate properly and perform
its intended function. Check for alignment of
moving parts, free running of moving parts,
breakage of parts, mounting and any other
conditions that may affect its operation. A guard or
other part that is damaged should be properly
repaired or replaced by an authorized service
center unless otherwise indicated in this
instruction manual. Have defective switches
replaced by an authorized service facility. Do not
use the tool if the switch does not turn it on and off.
10. Watch out for flying sparks when operating.
They can cause injury or ignite combustible
materials.
11. Do not touch the blade, workpiece or cutting
chips immediately after operation; they may be
extremely hot and could burn your skin.
12. If the blade stops during operation, makes an
odd noise or begins to vibrate, switch off the
tool immediately. Then check the tool and
blade.

When mounting the blade, make sure that the
direction of the arrow on the surface of the blade
matches the direction of the arrow on the blade
case.
Use only the Makita socket wrench provided to
install or remove the blade. Failure to do so may

•
Always set the vise nut to the right fully when
securing the workpiece. Failure to do so may result
in insufficient securing of the workpiece. This could
cause the workpiece to be ejected or cause
damage to the blade.

By turning the vise handle counterclockwise and then
flipping the vise nut to the left, the vise is released from
the shaft threads and can be moved rapidly in and out. To
grip workpieces, push the vise handle until the vise plate
contacts the workpiece. Flip the vise nut to the right and
then turn the vise handle clockwise to securely retain the
workpiece.
OPERATION
Cutting operation
CAUTION:
•
Never attempt to cut workpieces less than 2 mm
thick except pipe or workpieces which cannot be
secured firmly with the vise. The piece cut off may
be caught by the blade, causing dangerous
scattering of chips and/or damage to the
carbide-tips. Possible serious injury may result.
Do not apply excessive pressure on the handle
when cutting. Too much pressure may result in
overload of the motor, decreased cutting efficiency
and/or damage to the carbide-tips or blade itself.
Too little pressure on the handle may result in more
sparks and premature blade wear.

Long workpieces must be supported by blocks of
non-flammable material on either side so that it will be
level with the base top.
Do not touch the blade, workpiece or cutting chips
immediately after operation; they may be extremely
hot and could burn your skin.
•
If the blade stops during operation, makes an odd
noise or begins to vibrate, switch off the tool
immediately. Replace cracked or damaged blade
with a new one.
•
•
Do not cut aluminum, wood, plastics, concrete, tiles,
etc.
Always use carbide-tipped saw blades appropriate
for your job. The use of inappropriate saw blades
may cause a poor cutting performance and/or
present a risk of personal injury.

Hold the handle firmly. Switch on the tool and wait until
the blade attains full speed. Then lower the handle gently
to bring the blade close to the workpiece. When the blade
makes contact, ease into the cut gently at first, then
gradually add pressure as the cutting position steadies.
Your pressure on the handle should be adjusted to
produce the minimum amount of sparks.
Cutting angles
A
When the cut is completed, switch off the tool and WAIT
UNTIL THE BLADE HAS COME TO A COMPLETE
STOP before returning the handle to the fully elevated
position. If the handle is raised while the blade is still
rotating, the piece cut off may be caught by the blade,
causing dangerous scattering of chips. When cutting
only part of the way into a workpiece, raise the handle
while the blade is rotating. Switching off during the cut
may cause damage to the carbide-tips as they contact
the workpiece.

Secure the workpiece in the vise as shown in the Figure
A and proceed to cut it. The saw blade life will be
shortened if the workpiece is cut as shown in the Fig B.
Cutting rectangles
CAUTION:
•
Do NOT cut the workpiece as shown in the Fig. C
since this may cause it to be ejected from the vise,
possibly resulting in injury.
The saw blade is subjected to greater wear when the
area A in the Fig. B is cut. Place a wooden block up
against the workpiece as shown in the Fig. D so that the
saw blade will enter area A at an angle. This will help to
extend the saw blade life.
The allowable cutting dimensions are reduced when a
wooden block is used. Use a wooden block whose
dimensions are equivalent to the maximum allowable
cutting dimensions minus the dimensions of the
workpiece to be cut. This will further minimize the
shortening of the saw blade life.

CAUTION:
•
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may
result.
003783
The saw blade is subjected to greater wear when the
areas A and B in figure F and figure G are cut. Place a
wooden block up against the workpiece as shown in
figure H and figure I so that the saw blade will enter areas
A and B at an angle. This will help to minimize the
shortening of the saw blade life.
The allowable cutting dimensions are reduced when a
wooden block is used. Use a wooden block whose
dimensions are equivalent to the maximum allowable
cutting dimensions minus the dimensions of the
workpiece to be cut. This will further minimize the
shortening of the saw blade life.

Replacing saw blade
Continuing to use a dull and worn blade may cause
motor overload and decreased cutting efficiency.
Replace with a new blade as soon as it is no longer
effective.
