. INTENDED USE
This tool is a Rotary Hammer for drill-
ing in concrete. In addition, the tool 
has a “rotation only mode” without 
hammering. The mode is suitable for 
metal-drilling, wood-drilling.
Read “Safety Instructions” booklet and 
the following before using.
. ADDITIONAL 
SAFETY RULES
 1)  Use auxiliary handle (support 
handle) supplied with the tool. 
Loss of control can cause personal 
injury.
  2)   Be aware that this tool is always 
in an operating condition, since it 
does not have to be plugged into 
an electrical outlet.
 3)  Hold power tools by insulat-
ed gripping surfaces when per-
forming an operation where the 
cutting tool may contact hidden 
wiring; contact with a “live” wire 
will make exposed metal parts of 
the tool “live” and shock the opera-
tor.
  4)  If the bit becomes jammed, im-
mediately turn the main switch off 
to prevent an overload which can 
damage the battery pack or mo-
tor. Use reverse motion to loosen 
jammed bits.
 5)  
Do not operate the Forward/Reverse 
lever when the main switch is on. The 
battery will discharge rapidly and dam-
age to the unit may occur.
  6)   Use only a dry, soft cloth for wiping 
the unit. Do not use a damp cloth, 
thinner, benzine, or other volatile 
solvents for cleaning.
 7)  
When storing or carrying the tool, set 
the Forward/Reverse lever to the cent-
er position (switch lock).
  8)   Do not strain the tool by holding 
the speed control trigger halfway (speed control mode) so that the 
motor stops. The protection cir-
cuit will activate and may prevent 
speed control operation. If this hap-
pens, release the speed control 
trigger and squeeze again for nor-
mal operation.
  9)   Be careful not to get dust inside the 
chuck.
 10)   Do not touch the rotating parts to 
avoid injury.
 11)  Do not continue to use the tool for 
a long time. Stop using the tool 
from time to time to avoid that the 
temperature of the motor rises too 
high.
 12)  Do not drop the tool.
 13) Wear ear protection. Exposure to 
noise can cause hearing loss.
 14)  Do not put the tool on the place 
where the chuck cover is de-
pressed. The bit may come off 
from the chuck cover and fall 
down when the chuck cover is de-
pressed. It may cause injuries.

Excessive (complete) discharging of Li-
ion batteries shortens their service life 
dramatically. The driver includes a battery 
protection feature designed to prevent 
excessive discharging of the battery pack.
•  The battery protection feature ac-
tivates immediately before the bat-
tery loses its charge, causing the 
battery low warning lamp to flash. 
•  If you notice the battery low warn-
ing lamp flashing, charge the bat-
tery pack immediately.
(2) Overheat warning lamp

Battery pack
For Appropriate Use of Bat tery Pack
Li-ion Battery Pack (EY9L80)
•  For optimum battery life, store the 
Li-ion battery pack following use 
without charging it.
•  When battery pack is not in use, 
keep it away from other metal ob-
jects like: paper clips, coins, keys, 
nails, screws, or other small met-
al objects that can make a connec-
tion from one terminal to another.
  Shorting the battery terminals togeth-
er may cause sparks, burns or a fire.
•  When operating the battery pack, make 
sure the work place is well ventilated.
•  When the battery pack is removed 
from the main body of the tool, re-
place the battery pack cover imme-
diately in order to prevent dust or dirt 
from contaminating the battery termi-
nals and causing a short circuit.
Battery Pack Life
The rechargeable batteries have a lim-
ited life. If the operation time becomes 
extremely short after recharging, re-
place the battery pack with a new one.
Battery Recycling
ATTENTION:
For environmental protection and 
recycling of materials, be sure that 
it is disposed of at an officially as-
signed location, if there is one in 
your country.
Battery charger
Charging
Cautions for the Li-ion Battery 
Pack
• Make sure the terminals of the 
battery charger are not contaminated 
with liquid, grease or other 
substances before charging the 
battery pack.
  If you notice the terminals of the 
battery charger contaminated, be 
sure to wipe or take them off before 
use. The life of the battery pack 
may adversely be affected when 
the terminals are clogged with the 
dust or dirt which becomes solid 
with liquid or grease.
• 
If the temperature of the battery 
pack falls approximately below -10°C 
(14°F), charging will automatically 
stop to prevent degradation of battery.
Common Cautions for the Li-
ion/Ni-MH/Ni-Cd Battery Pack
•  The ambient temperature range is be-
tween 0°C (32°F) and 40°C (104°F).
  If the battery pack is used when the bat-
tery temperature is below 0°C (32°F), 
the tool may fail to function properly.
•  When charging a cool battery 
pack (below 0°C (32°F)) in a warm 
place, leave the battery pack at the 
place and wait for more than one 
hour to warm up the battery to the  
						

							- 10 - 
level of the ambient temperature.
•  Cool down the charger when charg-
ing more than two battery packs con-
secutively.
•  Do not insert your fingers into con-
tact hole, when holding charger or 
any other occasions.
CAUTION:
To prevent the risk of fire or dam-
age to the battery charger.
•  Do not use power source from an 
engine generator.
•  Do not cover vent holes on the 
charger and the battery pack.
• 
Unplug the charger when not in use.
Li-ion Battery Pack
NOTE:
Your battery pack is not fully charged 
at the time of purchase. Be sure to 
charge the battery before use.
Battery charger (EY0L80)
  1.  Plug the charger into the AC outlet.
NOTE:
Sparks may be produced when the 
plug is inserted into the AC power 
supply, but this is not a problem in 
terms of safety.
  2.  Insert the battery pack firmly into 
the charger.
 1 Line up the alignment marks and 
  place the battery onto the dock on 
 the charger.
  2  Slide forward in the direction of 
 the arrow.
 
Alignment marks
  3.  During charging, the charging lamp 
will be lit.
  
When charging is completed, an inter-
nal electronic switch will automatically 
be triggered to prevent overcharging.
• Charging will not start if the battery 
pack is warm (for example, immedi-
ately after heavy-duty operation).
  The orange standby lamp will be 
flashing until the battery cools down. 
Charging will then begin automatically.
  4.  The charge lamp (green) will 
flash slowly once the battery is 
approximately 80% charged.
  5.  When charging is completed, the 
charging lamp will start flashing 
quickly in green color.
 6. 
If the temperature of the battery pack 
is 0°C (32°F) or less, charging takes 
longer to fully charge the battery pack 
than the standard charging time. 
Even when the battery is fully charged, 
it will have approximately 50% of the 
power of a fully charged battery at 
normal operating temperature.
 7. If the power lamp does not light 
immediately after the charger is 
plugged in, or if after the standard 
charging time the charging lamp 
does not flash quickly in green, con-
sult an authorized service center.
  8.  If a fully charged battery pack is in-
serted into the charger again, the
