CORDLESS ROTARY HAMMER SAFETY
WARNINGS
1. Wear ear protectors.
Exposure to noise can cause hearing loss.
2. Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
3. Always charge the battery at a temperature of 0 – 40°C.
A temperature of less than 0°C will result in over charging
which is dangerous. The battery cannot be charged at a
temperature higher than 40°C.
The most suitable temperature for charging is that of 20 –
25°C.
4. Do not use the charger continuously.
When one charging is completed, leave the charger for
about 15 minutes before the next charging of battery.
5. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
6. Never disassemble the rechargeable battery and
charger.
7. 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.
8. Do not dispose of the battery in fi re.
If the battery is burnt, it may explode.
9. When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch. Please leave
it without using it for approximately 15 minutes.
10. 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.
11. Using an exhausted battery will damage the charger.
12. When drilling in wall, fl oor or ceiling, check for buried
electric power cord, etc.
13. 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.
14. Do not touch the bit during or immediately after operation.
The bit becomes very hot during operation and could
cause serious burns.
15. Always hold the body handle and side handle of the
power tool fi rmly. Otherwise the counterforce produced
may result in inaccurate and even dangerous operation.
16. Wear a dust mask
Do not inhale the harmful dusts generated in drilling or
chiseling operation. The dust can endanger the health of
yourself and bystandersy.

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 and 2 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 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.
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.
5. Do not connect directly to an electrical outlets or car
cigarette lighter sockets.
6. Do not use the battery for a purpose other than those

7. If the battery charging fails to complete even when a
specifi ed recharging time has elapsed, immediately stop
further recharging.
8. Do not put or subject the battery to high temperatures or
high pressure such as into a microwave oven, dryer, or
high pressure container.
9. Keep away from fi re immediately when leakage or foul
odor are detected.
10. Do not use in a location where strong static electricity
generates.
11. If there is battery leakage, foul odor, heat generated,
discolored or deformed, or in any way appears abnormal
during use, recharging or storage, immediately remove it
from the equipment or battery charger, and stop use.
CAUTION
1. If liquid leaking from the battery gets into your eyes, do not
rub your eyes and wash them well with fresh clean water
