II.   GENERAL SAFETY 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 
accidents. 2) 
Do  not  operate  power  tools  in 
explosive  atmospheres,  such  as  in 
the  presence  of  flammable  liquids, 
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

tools.
  Unmodified  plugs  and  matching 
outlets will reduce risk of electric 
shock.
2)  Avoid  body  contact  with  earthed  or 
grounded  surfaces  such  as  pipes, 
radiators, ranges and refrigerators.
  There is an increased risk of electric 
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 
increase 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 increase  the risk of electric shock.
5)  When  operating  a  power  tool 
outdoors,  use  an  extension  cord 
suitable for outdoor use.
  Use of a cord suitable for outdoor use 
reduces the risk of electric shock.
This  tool,  as  a  complete  unit  with  a  battery  pack, 
satisfies  appropriate  IP  Degrees  of  Protection  
based on the IEC regulations .
Definition of IP code
IP5X:  Ingress of  dust  is  not  totally  prevented,  
but  dust  shall  not  penetrate  in  a  quantity  to 
interfere with  satisfactory operation of the tool  
or  to  impair  safety  (In  case  that  the  talcum  
powder under 75  m intrudes inside the tool).  
IPX6:  Water projected in powerful jets  against 
t he  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) .
LIMITED WARRANTY
The  rating  of  IP56  qualifies  this  tool  for  the 
minimum  impact  of  water  or  dust,  but  not  for

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 
operating  power  tools  may  result  in 
personal 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.
3)  Avoid  accidental  starting.  Ensure 
the  switch  is  in  the  off  position 
before plugging in.
  Carrying  power  tools  with  your  finger 
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 
application.
  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 
controlled with the switch is dangerous 
and must be repaired.
3)  Disconnect the plug from the power 
source and/or the battery pack from 
the  power  tool  before  making  any 
adjustments, changing accessories, 
or storing power tools.
  Such  preventive  safety  measures 
reduce  the  risk  of  starting  the  power 
tool accidentally.
4)  Store  idle  power  tools  out  of  the 
reach  of  children  and  do  not  allow 
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  moving 
parts,  breakage  of  parts  and  any 
other  condition  that  may  affect  the 
power  tools  operation.  If  damaged, 
have the power tool repaired 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 control.
7)  Use  the  power  tool,  accessories 
and  tool  bits  etc.  in  accordance 
with  these  instructions  and  in  the 
manner  intended  for  the  particular 
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 
position  before  inserting  battery 
pack.
  Inserting  battery  pack  into  power 
tools  that  have  the  switch  on  invites 
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 
specifically  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 
objects  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 together  may cause burns, or a fire.
5)  Under  abusive  conditions,  liquid 
may  be  ejected  from  battery;  avoid 
contact.  If  contact  accidentally 
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 SAFETY 
RULES

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 
gripping  surfaces  when  performing 
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 operator.
4)  Be aware that this tool is always in an 
operating  condition,  since  it  does  not 
have  to  be  plugged  into  an  electrical 
outlet.
5)  If  the  bit  becomes  jammed, 
immediately  turn  the  trigger  switch 
off  to  prevent  an  overload  which  can 
damage  the  battery  pack  or  motor. 
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  holding  the 
speed  control  trigger  halfway  (speed 
control mode) so that the motor stops. 
The  protection  circuit  will  activate  and 
may  prevent  speed  control  operation. 
If this happens, release the speed 
control  trigger  and  squeeze  again  for 
normal 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 
become  slightly  warm.  This  is  normal. 
Do  NOT  charge  the  battery  for  a  long 
period.
