I. 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  mains  operated  (corded) 
p o w e r   t o o l   a n d   b a t t e r y   o p e r a t e d 
(cordless) power tool.
SAVE THESE INSTRUCTIONS
Work Area Safety
1)  Keep work area clean and well lit.Cluttered or dark areas invite accidents.
) 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 
way.  Do  not  use  any  adapter  plugs 
with earthed (grounded) power tools.
Unmodified  plugs  and  matching  outlets 
will reduce risk of electric shock.


)  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 
t h e   c o r d   f o r   c a r r y i n g ,   p u l l i n g   o r 
u n p l u g g i n g   t h e   p o w e r   t o o l .   K e e p 
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.
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.

)  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)

  D o   n o t   o v e r r e a c h .   K e e p   p r o p e r 
footing and balance at all times. 
This enables better control of the power 
tool in unexpected situations.
6)

  Dress  properly.  Do  not  wear  loose 
c l o t h i n g   o r   j e w e l l e r y.   K e e p   y o u r 
hair,  clothing  and  gloves  away  from 
moving parts.
Loose clothes, jewellery or long hair can 
be caught in moving parts.
7)

  I f   d e v i c e s   a r e   p r o v i d e d   f o r   t h e 
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.


)  D o   n o t   u s e   t h e   p o w e r   t o o l   i f   t h e 
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  
						

							- 5 -  
the  power  tool  before  making  any 
adjustments,  changing  accessories, 
or storing power tools. 
S u c h   p r e v e n t i v e   s a f e t y   m e a s u r e s 
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)
  M a i n t a i n   p o w e r   t o o l s .   C h e c k   f o r 
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)

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 
d i ff e r e n t   f r o m   t h o s e   i n t e n d e d   c o u l d 
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.


)  R e c h a r g e   o n l y   w i t h   t h e   c h a r g e r 
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.

tool is maintained.
II. INTENDED USE
This  tool  is  a  Cordless  Impact  Driver/Wrench 
and  can  be  used  to  tighten  bolts,  nuts,  and 
screws. Additionally, it provides a torque control 
function that automatically stops tool operation 
when a preset load is reached to deliver consis-
tent tightening torque. Additionally, a separately 
available Assembly  Qualifier  can  provide  wire -
less monitoring to determine whether tightening 
has been completed properly.
Read “the Safety Instructions” booklet 
and the following before using.
III.  ADDITIONAL SAFETY 
RULES
1)  Wear  ear  protectors  when  using  the 
tool for extended periods.

(2) The battery indication lamp
• Use  the  battery  indication  lamp  to  check 
how much power is left in the battery.
•
  Battery  life  varies  slightly  with  ambient  tem-
perature  and  battery  characteristics.  The 
lamp  is  designed  to  provide  a  rough  indica-
tion of remaining battery life.

Automatic power­off function
• The automatic power-off function is designed 
to  prevent  a  loss  of  tightening  torque  due  to 
reduced  battery  voltage.  Once  it  has  been 
activated,  the  tool  will  not  operate  until  the 
battery  pack  has  been  charged  (or  replaced 
with  a  fresh  unit),  even  if  the  trigger  is 
depressed.

Flashing
NOTE: •  All 3 bars on the battery indication lamp 
will  flash  when  the  automatic  power-off 
function is activated.
•

  When the battery indication lamp begins 
flashing,  the  battery  pack  should  be 
charged  (or  replaced  with  a  fresh  unit) 
immediately.
•

  Be  sure  to  fully  charge  the  battery  pack 
in  question  after  activation  of  the  auto-
matic  power-off  function.  Failure  to  do 
so  may  prevent  the  automatic  power-off 
function from being properly deactivated.
(3)  The torque control function
• The  torque  control  function  calculates  the 
load from the motor’s rotational angle during 
the  hammer  impact  and  determines  that  the 
bolt  has  been  properly  seated  when  a  pre-
set  load  value  is  exceeded.  Driving  is  then 
automatically stopped after a preset number 
of impacts have been delivered to the bolt. 
CAUTION: •
  A l w a y s   c h e c k   t h e   t o o l ’s   t i g h t e n i n g 
torque before use. Improper tool opera-
tion  may  result  in  excessive  or  inad-
equate tightening. 
CAUTION: •
  Always  operate  the  tool  with  the  switch 
fully  engaged.  The  torque  control  func-
tion  will  not  operate  when  the  switch  is 
not  sufficiently  engaged,  preventing  the 
tool from stopping automatically.
•

  In  work  where  a  heavy  load  comes  to 
bear during tightening, the load may be 
interpreted  as  the  seating  of  the  bolt, 
preventing  the  bolt  from  being  com-
pletely tightened.
•

  Repeated  tightening  of  the  same  bolt 
may break the bolt or deform the mate-
rial into which the bolt is being driven as 
a result of excessive tightening.
•

  The  tightening  torque  value  and  preci -
sion vary with factors such as the mate-
rial  into  which  the  bolt  is  being  driven 
and  the  condition  of  the  socket  being 
used.  Adjust  the  torque  as  necessary 
for the work being performed. Bolt tight-
