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. 
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.
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.
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.
 
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.
  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.
 
 Use of a cord suitable for outdoor use 
reduces the risk of electric shock.
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.

							- 4 - 
 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.
  3)  Avoid accidental starting. Ensure 
the switch is in the off position 
before plugging in. 
  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.
Power Tool Use and Care
  1) Do not force the power tool. Use 
the correct power tool for your ap-
plication.
 The correct power tool will do the 
job better and safer at the rate for 
which it was designed.
 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.
  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.
 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.
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.
  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.
  3)  Use power tools only with specif-
ically designated battery packs.
  Use of any other battery packs 
may create a risk of injury and fire.

 4) 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 metal 
objects that can make a connection 
from one terminal to another.
 Shorting the battery terminals to-
gether may cause burns, or a fire.
  5)  Under abusive conditions, liq-
uid may be ejected from battery; 
avoid contact. If contact acciden-
tally occurs, flush with water. If 
liquid contacts eyes, additionally 
seek medical help.
  Liquid ejected from the battery may 
cause irritation or burns.
Service
  1)  Have your power tool serviced by 
a qualified repair person using 
only identical replacement parts. 
  This will ensure that the safety of 
power tool is maintained.
III.  SPECIFIC SAFE-
TY RULES
 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)  Hold power tools by insulated 
grip  ping sur  faces when perform-
ing an operation where the cutting 
tool may contact hid  den wiring.
 Contact with a “live” wire will make 
ex  posed metal parts of the tool 
“live” and shock the operator.
  4)  
Be aware that this tool is always in 
an operating condition, since it does 
not have to be plugged into an elec-
trical outlet.
 5) If the bit becomes jammed, imme-
diately turn the trigger switch off 
to prevent an overload which can 
damage the battery pack or mo-
tor. Use reverse motion to loosen 
jammed bits.
 6) Do not operate the Forward/Reverse 
lever when the trigger switch is on. 
The battery will discharge rapidly 
and damage to the unit may occur.
  7)  When storing or carrying the tool, 
set the Forward/Reverse lever to 
the center position (switch lock).
  8)  Do not strain the tool by hold-
ing the speed control trigger half-
way (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 use the tool continuously for a 
long period of time. Stop using the tool 
from time to time to avoid temperature 
rise and heat overload of the motor.
 
12)  Do not drop the tool. 13) Wear dust mask, if the work causes 
dust.
 14) During charging, the charger may be-
come slightly warm. This is normal. 
Do NOT charge the battery for a long 
period.
