WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS.
 Failure to follow all instructions listed below,  may  result  in  electric  shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
 1) Keep your work area clean and well lit. Cluttered  benches  and  dark  areas invite accidents.
 2) D o   n o t   o p e r a t e   p o w e r   t o o l s   i n  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 bystanders, children, and vis-itors  away  while  operating  a  power tool.  Distractions  can  cause  you  to  lose control.  Make  sure  that  no  one  is beneath,  or  on  the  other  side  of  the area when you are working.
Electrical Safety
 4) A  battery  operated  tool  with  integral batteries or a separate battery pack must  be  recharged  only  with  the specified charger for the battery. A  charger  that  may  be  suitable  for one  type  of  battery  may  create  a  risk of  fire  when  used  with  another  bat-
tery.
 5) Use  battery  operated  tool  only  with s p e c i f i c a l l y   d e s i g n a t e d   b a t t e r y  pack.  Use of any other batteries may create a risk of fire.
Personal Safety
 6) S t a y   a l e r t ,   w a t c h   w h a t   y o u   a r e  d o i n g ,   a n d   u s e   c o m m o n   s e n s e  when  operating  a  power  tool.  Do not  use  tool  while  tired  or  under the  influence  of  drugs,  alcohol,  or medication. A  moment  of  inattention  while  operat-ing  power  tools  may  result  in  serious personal injury.
 7) Dress  properly.  Do  not  wear  loose clothing  or  jewelry.  Contain  long hair.   K e e p   y o u r   h a i r,   c l o t h i n g ,   a n d  gloves away from moving parts. Loose  clothes,  jewelry,  or  long  hair can be caught in moving parts.
 8) Avoid  accidental  starting.  Be  sure switch  is  in  the  locked  or  off  posi-tion before inserting battery pack.  Carrying  tools  with  your  finger  on  the switch  or  inserting  the  battery  pack into  a  tool  with  the  switch  on  invites accidents.
 9) Remove  adjusting  keys  or  wrench-es before turning the tool on.  A wrench or a key that is left attached t o   a   r o t a t i n g   p a r t   o f   t h e   t o o l   m a y  result in personal injury.
 10) 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.  Proper  footing  and  balance  enable better  control  of  the  tool  in  unexpect-ed situations.
 11) Use safety equipment. Always wear eye protection.  Dust  mask,  non-skid  safety  shoes, hard  hat,  or  hearing  protection  must be used for appropriate conditions.
Tool use and care
 12) Use  clamps  or  other  practical  way to  secure  and  support  the  work-piece to a stable platform.  Holding  the  work  by  hand  or  against your  body  is  unstable  and  may  lead to loss of control.
 13) Do  not  force  tool.  Use  the  correct 
tool for your application.  The  correct  tool  will  do  the  job  better and  safer  at  the  rate  for  which  it  is designed. 
						

							- 2 - - 3 -  
 14) Do  not  use  tool  if  switch  does  not turn it on or off.  A  tool  that  cannot  be  controlled  with the  switch  is  dangerous  and  must  be repaired.
 15) Disconnect  battery  pack  from  tool or  place  the  switch  in  the  locked or  off  position  before  making  any adjustments,  changing  accessories, or storing the tool.  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  tool accidentally.
 16) Store idle tools out of reach of chil-dren and other untrained persons.  Tools  are  dangerous  in  the  hands  of untrained users.
 17) 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  togeth-er may cause sparks, burns or a fire.
 18) Maintain  tools  with  care.  Keep  cut-ting tools sharp and clean.  Properly  maintained  tools  with  sharp cutting  edge  are  less  likely  to  bind and are easier to control.
 19) Check  for  misalignment  or  binding  of moving  parts,  breakage  of  parts,  and any  other  condition  that  may  affect the  tool’s  operations.  If  damaged, have the tool serviced before using.  Many accidents are caused by poorly maintained tools.
 20) Use  only  accessories  that  are  rec-ommended by the manufacturer for your model. Accessories  that  may  be  suitable  for one  tool  may  create  a  risk  of  injury when used on another tool.
Service
 21) Tool  service  must  be  performed only by qualified repair personnel. Service or maintenance performed by unqualified  personnel  may  result  in  a risk of injury.
 22) When  servicing  a  tool,  use  only identical  replacement  parts.  Follow instructions  in  the  Maintenance section of this manual.  Use  of  unauthorized  parts  or  failure to  follow  Maintenance  Instructions may create a risk of shock or injury.
.SPECIFIC  SAFETY 
RULES
 1) Hold tool by insulated gripping sur-faces  when  performing  an  opera-tion  where  the  cutting  tool  may contact hidden wiring. Contact  with  a  “live”  wire  will  also make  exposed  metal  parts  of  the  tool “live” and shock the operator.
 2) Wear ear protectors when using the tool for extended periods. Prolonged  exposure  to  high  intensity noise can cause hearing loss.
 3) Be  aware  that  this  tool  is  always  in an  operating  condition, it  does  not have  to  be  plugged  into  an  electrical outlet.
 4) D o   n o t   o p e r a t e   t h e   F o r w a r d /Reverse  lever  when  the  Variable speed control trigger is on. The battery will discharge rapidly and damage to the unit may occur.
 5) If  the  bit  becomes  jammed,  imme- diately turn the Variable speed con-trol  trigger  off  to  prevent  an  over-load  which  can  damage  the  battery pack  or  motor.  Use  reverse  motion to loosen jammed bits.
 6) When  storing  or  carrying  the  tool, set  the  Forward/Reverse  lever  to the center (switch lock) position.
 7) Do  not  strain  the  tool  by  holding the  speed  control  trigger  halfway (speed  control  mode)  so  that  the motor stops.

CAUTION:Test the setting before actual operation.
Set the scale at this mark (  ). 
Speed Selection
Choose  a  low  or  high  speed  to  suit the use.The  more  the  speed  control  trigger  is pulled, the higher the speed becomes.
CAUTION: Check  the  speed  selector  switch before use.
  Use  at  low  speed  when  strong f o r c e   i s   n e e d e d   d u r i n g   o p e r a-
tion.  (Using  at  high  speed  while  a strong  force  is  applied  may  cause a motor breakdown.)
  Do  not  operate  the  speed  selector switch  (LOW-HIGH)  while  pulling on  the  speed  control  trigger.  This can  cause  the  rechargeable  bat-tery to wear quickly or damage the internal mechanism of the motor.
* S e e   a p p e n d i x   f o r   “ R E C O M -MENDED SPEED SELECTION”.
NOTE:When  the  brake  operates,  a  brak-ing sound may be heard. This  sound  indicates  engagement of the bit lock.
CAUTION:  To  eliminate  excessive  temperature increase  of  the  tool  surface,  do  not operate  the  tool  continuously  using two  or  more  battery  packs.  Tool needs cool off time before switching to another pack.
 Do  not  close  up  vent  holes  on  body sides  of  the  body  during  operation. Otherwise,  the  machine  function  is adversely affected to cause a failure.
 Do  not  strain  the  tool  (motor).  This may cause damage to the unit.
 Use  the  machine  in  such  a  way  as to prevent the air from the body vent holes from blowing directly onto your skin. Otherwise, you may get burnt.
 When  operating  with  a  Ni-MH  bat-tery  pack,  make  sure  the  place  is well-ventilated.
Bit-locking function
 1. With  the  trigger  switch  not  engaged and  a  screwdriver  bit  locked  in  place, the  tool  can  be  used  as  a  manual screwdriver (up to 22.6 Nm, 230 kf-cm, 
199 in-lbs).   There  will  be  a  little  play  in  the  chuck, but this is not a malfunction.
 2. This  feature  is  handy  for  tightening screws  that  require  more  torque  than the maximum torque of the driver (posi-
tion   on  the  clutch),  for  confirming  the tightness  of  a  screw  or  to  loosen  an extremely tight screw.

Battery pack
Ni-MH Battery pack (EY9251)
  Charge  the  Ni-MH  battery  fully  before storage  in  order  to  ensure  a  longer  ser-vice life.
  The  ambient  temperature  range  is  be-tween 0°C (32°F) and 40°C (104°F).   If the battery pack is used when the bat-tery temperature is below 0°C (32°F), the tool  may  fail  to  function  properly.    In  that case, charge the battery until charging is completed  for  appropriate  functioning  of the battery.
  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 con-nection from one terminal to another.   Shorting  the  battery  terminals  together may cause sparks, burns or a fire.
  When  operating  with  a  Ni-MH  bat-tery pack, make sure the place is well-ventilated.
Battery Pack Life
The  rechargeable  batteries  have  a  lim-ited  life.  If  the  operation  time  becomes e x t r e m e l y   s h o r t   a f t e r   r e c h a r g i n g ,  replace the battery pack with a new one.
NOTE:Use  under  extremely  hot  or  cold conditions  will  reduce  operating capacity per charge.
Charging
NOTE:When  you  charge  the  battery  pack for  the  first  time,  or  after  prolonged s t o r a g e ,   c h a r g e   i t   f o r   a b o u t   2 4  hours  to  bring  the  battery  up  to  full capacity.
Battery charger (EY0110)
 1. Plug the charger into the AC outlet.
NOTE:
Sparks may be produced when the 
plug  is  inserted  into  the  AC  power 
supply,  but  this  is  not  a  problem  in 
terms of safety.
 2. Insert  the  battery  pack  firmly  into  the 
charger.

 3. During  charging,  the  charging  lamp  will 
be lit.
When  charging  is  completed,  an  inter
-
nal  electronic  switch  will  automatically 
be triggered to prevent overcharging.
  Charging  will  not  start  if  the  battery 
pack  is  warm  (for  example,  immedi-
ately after heavy-duty operation).
  The  orange  standby  lamp  will  be  lit 
until  the  battery  cools  down.  Charging 
will then begin automatically.
  4. W h e n   c h a r g i n g   i s   c o m p l e t e d ,   t h e  
charging  lamp  will  start  flashing  quickly 
in green color.
  5. When  in  any  of  the  conditions  that 
battery  pack  is  too  cool,  or  the  bat-
tery  pack  has  not  been  used  for  a 
long  time,  the  charging  lamp  is  lit.  In 
this  case,  charging  takes  longer  to 
fully  charge  the  battery  pack,  than  the 
standard charging time.
  If a fully charged battery pack is insert-
ed into the charger again, the charging 
lamp  light  up.  After  several  minutes, 
the charging lamp may flash quickly to 
indicate the charging is completed.
  6. If  the  charging  lamp  does  not  light  im-
mediately  after  the  charger  is  plugged 
in,  or  if  after  the  standard  charging 
time  the  lamp  does  not  go  off,  consult 
an authorized dealer.
