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.
) 
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.
) 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.
) 
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.
) 
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.
) 
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.

 INTENDED USE
This tool is a Cordless Impact Wrench and can be used to tighten bolts, nuts, and screws. Ad-ditionally,  it  provides  a  torque  control  function that  automatically  stops  tool  operation  when a  preset  load  is  reached  to  deliver  consistent 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.
)  Be  aware  that  this  tool  is  always  in  an 
operating  condition,  since  it  does  not  have to be plugged into an electrical outlet.
)  Hold  power  tools  by  insulated  gripping 
surfaces  when  performing  an  operation 
where  the  cutting  tool  may  contact  hid­den wiring or its own cord.
  Contact with a “live” wire will make ex­posed 
metal  parts  of  the  tool  “live”  and  shock  the operator.
4)  Do  NOT  operate  the  Forward/Reverse 
lever when the main switch is on. The bat-tery  will  discharge  rapidly  and  damage  to the unit may occur.
)  During  charging,  the  charger  may  become 
slightly warm. This is normal.
  Do NOT charge the battery for a long period.
6)  When  storing  or  carrying  the  tool,  set  the

NOTE:
• The tightening confirmation lamp will not 
turn on under the following conditions:
•  When the torque clutch is set to “F”
•  During reverse rotation operation
•  The  lamp  turns  off  when  the  tool  is  in 
operation.
Control Panel
(1) ()()
(1) 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:
• Always check the tool’s tightening torque before  use.  The  required  adjustment is  dependent  on  the  type  of  threaded connection  and  can  be  best  determined by  practical  trials.  Check  the  trial  screw-ings with a torque wrench. Improper tool operation  may  result  in  excessive  or inadequate tightening.• Always  operate  the  tool  with  the  switch fully  depressed.  The  torque  control f u n c t i o n   w i l l   n o t   o p e r a t e   w h e n   t h e switch is not sufficiently depressed, pre-venting the tool from stopping automati-cally.
•  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.
