This tool, as a complete unit with a battery  
pack, satisfies appropriate IP Degrees of  
Protection based on the IEC regulations.  
SAVE THESE INSTRUCTIONS  
Work Area Safety  
1) Keep work area clean and well lit.  
Cluttered or dark areas invite acci-  
dents.  
2) Do not operate power tools in ex-  
plosive atmospheres, such as in  
the presence of flammable liq-  
uids, gases or dust.  
Power tools create sparks which  
may ignite the dust or fumes.  
3) Keep children and bystanders  
away while operating a power tool.  
Distractions can cause you to lose  
control.  
Definition of IP code  
IP5X: Ingress of dust is not total-  
ly prevented, but dust shall not pen-  
etrate in a quantity to interfere with  
satisfactory operation of the tool or to  
impair safety (In case that the talcum  
powder under 75 μm intrudes inside  
the tool).  
IPX6: Water projected in powerful jets  
against the tool from any direction  
shall have no harmful effects (In case  
that, with a nozzle of 12.5 mm inner  
diameter, approximately 100 L/min of  
normal temperature water is injected  
to the tool for 3 minutes from 3 meter  
distance).  
Electrical Safety  
1) Power tool plugs must match  
the outlet. Never modify the  
plug in any way. Do not use  
any adapter plugs with earthed  
(grounded) power tools.  
LIMITED WARRANTY  
The rating of IP56 qualifies this tool  
for the minimum impact of water or  
dust, but not for the assurance of per-  
formance in such conditions. See  
Safety and Operating Instructions for  
further details for proper operation.  
Unmodified plugs and matching out-  
lets will reduce risk of electric shock.  
2) Avoid body contact with earthed  
or grounded surfaces such as  
pipes, radiators, ranges and refrig-  
erators.  
There is an increased risk of elec-  
tric shock if your body is earthed or  
grounded.  
I. INTRODUCTION  
These tools can be used to tight-  
en screws in clutch mode and to  
drill holes in wood and metal in drill  
mode. Additionally, model EY7950  
can be used to drill holes in soft con-  
crete and similar materials in ham-  
mer mode.  
3) Do not expose power tools to  
rain or wet conditions.  
Water entering a power tool will in-  
crease the risk of electric shock.  
4) Do not abuse the cord. Never use  
the cord for carrying, pulling or  
unplugging the power tool. Keep  
cord away from heat, oil, sharp  
edges or moving parts.  
Damaged or entangled cords in-  
crease the risk of electric shock.  
5) When operating a power tool out-  
doors, use an extension cord suit-  
able for outdoor use.  
II. GENERAL SAFE-  
TY RULES  
WARNING! Read all instructions  
Failure to follow all instructions listed  
below may result in electric shock, fire  
and/or serious injury. The term “power tool”  
in all of the warnings listed below refers to  
your main operated (corded) power tool  
and battery operated (cordless) power tool.  
Use of a cord suitable for outdoor use  
reduces the risk of electric shock.

2) Do not use the power tool if the  
switch does not turn it on and off.  
Any power tool that cannot be con-  
trolled with the switch is dangerous  
and must be repaired.  
3) Disconnect the plug from the pow-  
er source and/or the battery pack  
from the power tool before making  
any adjustments, changing acces-  
sories, or storing power tools.  
Such preventive safety measures  
reduce the risk of starting the pow-  
er tool accidentally.  
Personal Safety  
1) Stay alert, watch what you are  
doing and use common sense  
when operating a power tool. Do  
not use a power tool while you  
are tired or under the influence  
of drugs, alcohol or medication.  
A moment of inattention while oper-  
ating power tools may result in per-  
sonal injury.  
2) Use safety equipment. Always  
wear eye protection.  
Safety equipment such as dust  
mask, non-skid safety shoes, hard  
hat, or hearing protection used for  
appropriate conditions will reduce  
personal injuries.  
4) Store idle power tools out of the  
reach of children and do not al-  
low persons unfamiliar with the  
power tool or these instructions  
to operate the power tool.  
3) Avoid accidental starting. Ensure  
the switch is in the off position  
before plugging in.  
Power tools are dangerous in the  
hands of untrained users.  
5) Maintain power tools. Check for  
misalignment or binding of mov-  
ing parts, breakage of parts and  
any other condition that may af-  
fect the power tools operation. If  
damaged, have the power tool re-  
paired before use.  
Many accidents are caused by  
poorly maintained power tools.  
6) Keep cutting tools sharp and clean.  
Properly maintained cutting tools  
with sharp cutting edges are less  
likely to bind and are easier to con-  
trol.  
7) Use the power tool, accessories  
and tool bits etc. in accordance  
with these instructions and in the  
manner intended for the particu-  
lar type of power tool, taking into  
account the working conditions  
and the work to be performed.  
Use of the power tool for operations  
different from those intended could  
result in a hazardous situation.  
Carrying power tools with your fin-  
ger on the switch or plugging in the  
power tools that have the switch on  
invites accidents.  
4) Remove any adjusting key or  
wrench before turning the power  
tool on.  
A wrench or a key left attached to a  
rotating part of the power tool may  
result in personal injury.  
5) Do not overreach. Keep proper  
footing and balance at all times.  
This enables better control of the  
power tool in unexpected situations.  
6) Dress properly. Do not wear  
loose clothing or jewelry. Keep  
your hair, clothing and gloves  
away from moving parts.  
Loose clothes, jewelry or long hair  
can be caught in moving parts.  
7) If devices are provided for the  
connection of dust extraction and  
collection facilities, ensure these  
are connected and properly used.  
Use of these devices can reduce  
dust related hazards.  
Battery Tool Use and Care  
1) Ensure the switch is in the off posi-  
tion before inserting battery pack.  
Inserting battery pack into pow-  
er tools that have the switch on in-  
vites accidents.  
Power Tool Use and Care  
1) Do not force the power tool. Use  
the correct power tool for your ap-  
plication.  
2) Recharge only with the charger  
specified by the manufacturer.  
A charger that is suitable for one type  
of battery pack may create a risk of fire  
when used with another battery pack.  
The correct power tool will do the  
job better and safer at the rate for  
which it was designed.

falls approximately below −10°C (14°F),  
charging will automatically stop to  
prevent degradation of the battery.

• The ambient temperature range is  
between 0°C (32°F) and 40°C (104°F).  
If the battery pack is used when the  
battery 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 level of the ambient  
temperature.  
• Cool down the charger when  
charging more than two battery packs  
consecutively.  
• Do not insert your fingers into contact  
hole, when holding charger or any other  
occasions.  
Excessive (complete) discharging of  
lithium ion batteries shortens their  
service life dramatically. The driver in-  
cludes a battery protection feature  
designed to prevent excessive dis-  
charging 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 warning  
lamp flashing, charge the battery  
pack immediately.  
To prevent the risk of fire or  
damage 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.
