4. Never short-circuit the rechargeable battery.
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
5. Do not dispose of the battery in fi re. If the battery is burnt,
it may explode.
6. Bring the battery to the shop from which it was purchased
as soon as the post-charging battery life becomes too
short for practical use. Do not dispose of the exhausted
battery.
7. Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or infl ammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
8. When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch. Therefore,
whenever the housing becomes hot, give the saw a
break for a while.
9. If the machine is used continuously at low speed, an
extra load is applied to the motor which can result in
motor seizure. Always operate the power tool so that
the blade is not caught by the material during operation.
Always adjust the blade speed to enable smooth cutting.
10. Always hold the body handle and front cover of the
power tool fi rmly as shown in Fig. 2. Otherwise the
counterforce produced may result in inaccurate and
even dangerous operation.
11. Mounting and dismounting the blade
○ Pull the back of the saw blade two or three times by hand
and check that the blade is securely mounted. When
pulling the blade, you will know it is properly mounted if it
clicks and the blade holder moves slightly. (Fig. 7)
○ When pulling the saw blade, be absolutely sure to pull it
from the back. Pulling other parts of the blade will result
in an injury.
○ Never touch the saw blade immediately after use. The
metal is hot and can easily burn your skin.
○ If the broken saw blade is hidden inside the small slit,
hook the broken blade using a tip of another saw blade
and take it out. (Fig. 9)
○ After use, blow away sawdust, earth, sand, moisture,
etc., with air or brush them away with a brush, etc., to
ensure that the blade mount can function smoothly.
○ Do not use any saw blade with a worn-out blade hole.
Otherwise, the saw blade can come off , resulting in

blade. Whenever the motor gets locked, switch it off
immediately.
19. Use clamps or another practical way to secure and
support the workpiece to a stable platform. (Fig. 14)
Holding the work by hand or against your body leaves it
unstable and may lead to loss of control.
20. When cutting metallic materials, use an appropriate
cutting fl uid (spindle oil, soapy water, etc.) to prolong the
bladeʼs service life.
21. Delay the feed speed when cutting the material into
small circular arcs. An unreasonably fast feed may break
the blade.
22. Plunge cutting
○ Avoid plunge cutting for metallic materials. This can
easily damage the blade.
○ Never pull the switch trigger while the tip of the saw
blade tip is pressed against the material. If you do so, the
blade can easily be damaged when it collides with the
material.
○ Make absolutely sure that you cut slowly while holding
the body fi rmly. If you apply any unreasonable force to
the saw blade during the cutting operation, the blade can
easily be damaged.
23. Keep the light ON during cutting operation only. If
it is lit ON in other cases, the main body switch can
be inadvertently turned ON, resulting in unexpected
accidents.
24. Do not expose directly your eye to the light by looking

5. Hold the charger fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period
is not activated, the electric discharge might be low when
using them the fi rst and second time. This is a temporary
phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2–3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery. If
you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate, and
the battery life will be shortened. Leave the battery and
recharge it after it has cooled for a while.
CAUTION
○ If the battery is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used, the
pilot lamp of the charger lights for 1 second, does not
light for 0.5 seconds (off for 0.5 seconds). In such a case,
fi rst let the battery cool, then start charging.
○ When the pilot lamp fl ickers (at 0.2-second intervals),
check for and take out any foreign objects in the charger’s
battery connector. If there are no foreign objects, it is
probable that the battery or charger is malfunctioning.
Take it to your authorized Service Center.

MAINTENANCE AND INSPECTION
CAUTION
Be sure to turned off the switch and remove the battery
before maintenance and inspection.
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
reduced cutting effi ciency and may cause overloading of
the motor. Replace the blade with a new one as soon as
excessive abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.

4. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
5. Cleaning on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
6. Storage
Store the power tool and battery in a place in which
the temperature is less than 40°C and out of reach of
children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
Important notice on the batteries for the HiKOKI
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modifi ed (such as
disassembly and replacement of cells or other internal
parts).
NOTE
Due to HiKOKI’s continuing program of research and
development, the specifi cations herein are subject to
change without prior notice.
