– Ensure that ventilation openings are kept clear when
working in dusty conditions, if it should become
necessary to clear dust, fi rst disconnect the tool from
the mains supply (use non metallic objects) and avoid
damaging internal parts;
– Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves, helmet
and apron should be worn;
– Pay attention to the wheel that continues to rotate after
the tool is switched o ff .
– Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
– Never disassemble the rechargeable battery and
charger.
– 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.
– Do not dispose of the battery in fi re. If the battery is burnt,
it may explode.
– Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or in fl ammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
– 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.
ADDITIONAL SAFETY WARNINGS
1. Ensure that the wheel to be utilized is the correct type
and free of cracks or surface defects. Also ensure that
the wheel is properly mounted and the collet chuck is
securely tightened.
2. To prolong the life of the machine and ensure a fi rst
class fi nish, it is important that the machine should not
be overloaded by applying too much pressure. In most
applications, the weight of the machine alone is su ffi cient
for e ff ective grinding. Too much pressure will result in
reduced rotational speed, inferior surface fi nish, and
overloading which could reduce the life of the machine.
3. The wheel continues to rotate after the tool is switched
o ff .
After switching o ff the machine, do not put it down until
the wheel has come to a complete stop. Apart from
avoiding serious accidents, this precaution will reduce
the amount of dust and swarf sucked into the machine.
4. Be careful of brake kickback.
This cordless die grinder features an electric brake that
functions when the switch is released. As there is some
kickback when the brake functions, be sure to hold the
main body securely.
5. Do not use the product if the tool or the battery terminals
(battery mount) are deformed.
Installing the battery could cause a short circuit that
could result in smoke emission or ignition.
6. Keep the tool’s terminals (battery mount) free of swarf
and dust.
○ Prior to use, make sure that swarf and dust have not
collected in the area of the terminals.
○ During use, try to avoid swarf or dust on the tool from
falling on the battery.
○ When suspending operation or after use, do not leave
the tool in an area where it may be exposed to falling
swarf or dust.
Doing so could cause a short circuit that could result in
smoke emission or ignition.
PRECAUTIONS FOR BATTERY AND
CHARGER
1. Always charge the battery at an ambient temperature of
-10–40°C. A temperature of less than -10°C will result in
over charging which is dangerous. The battery cannot be
charged at a temperature greater than 40°C.
The most suitable temperature for charging is that of
20–25°C.
2. Do not use the charger continuously.
When one charging is completed, leave the charger for
about 15 minutes before the next charging of battery.
3. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
4. Never disassemble the rechargeable battery or charger.
5. Never short-circuit the rechargeable battery.
Short-circuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
6. Do not dispose of the battery in fi re.
If the battery is burnt, it may explode.
7. Using an exhausted battery will damage the charger.
8. 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.
9. Do not insert objects into the air ventilation slots of the
charger.
Inserting metal objects or fl ammable into the charger air
ventilation slots will result in an electrical shock hazard or
damage to the charger.
CAUTION ON LITHIUM-ION BATTERY
To extend the lifetime, the lithium-ion battery equips with the
protection function to stop the output.
In the cases of 1 to 3 described below, when using this
product, even if you are pulling the switch, the motor may
stop. This is not the trouble but the result of protection
function.
1. When the battery power remaining runs out, the motor
stops.
In such a case, charge it up immediately.
2. If the tool is overloaded, the motor may stop. In this
case, release the switch of tool and eliminate causes of
overloading. After that, you can use it again.
3. If the battery is overheated under overload work, the
battery power may stop.
In this case, stop using the battery and let the battery
cool. After that, you can use it again.
Furthermore, please heed the following warning and caution.
WARNING
In order to prevent any battery leakage, heat generation,
smoke emission, explosion and ignition beforehand, please
be sure to heed the following precautions.
1. Make sure that swarf and dust do not collect on the
battery.
○ During work make sure that swarf and dust do not fall on
the battery.
○ Make sure that any swarf and dust falling on the power
tool during work do not collect on the battery.
○ Do not store an unused battery in a location exposed to
swarf and dust.
○ Before storing a battery, remove any swarf and dust that
may adhere to it and do not store it together with metal
parts (screws, nails, etc.).
2. Do not pierce battery with a sharp object such as a
nail, strike with a hammer, step on, throw or subject the
battery to severe physical shock.
3. Do not use an apparently damaged or deformed battery.
4. Do not use the battery in reverse polarity.
