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.
)

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

Common  Cautions  for  the  Li­
ion/Ni­MH/Ni­Cd Battery Pack
NOTE:• When  charging  a  cool  battery  pack (below  0°C  (3°F))  in  a  warm  place, leave  the  battery  pack  at  the  place  and wait for more than one hour to warm up the  battery  to  the  level  of  the  ambient temperature.  Otherwise  battery  pack may not be fully charged.• Cool  down  the  charger  when  charging more than two battery packs consecutively.• Do  not  insert  your  fingers  into  contact hole, when holding charger or any other occasions.
CAUTION:To  prevent  the  risk  of  fire  or  damage  to the battery charger.
• D o   n o t   u s e   p o w e r   s o u r c e   f r o m   a n engine generator.• Do  not  cover  vent  holes  on  the  charger and the battery pack.• Unplug the charger when not in use.

Alignment marks
3. During  charging,  the  charging  lamp  will  be lit.When  charging  is  completed,  an  internal electronic  switch  will  automatically  be  trig-gered to prevent overcharging.•  Charging  will  not  start  if  the  battery pack is warm (for example, immediately after heavy-duty operation).  The  orange  standby  lamp  will  be  flash-ing until the battery cools down.  Charging will then begin automatically.
4. The  charge  lamp  (green)  will  flash  slowly once  the  battery  is  approximately  80% charged.
5. When  charging  is  completed,  the  charging lamp will start flashing quickly in green color.
6.  If  the  temperature  of  the  batter  pack  is   0°C  or  less,  charging  takes  longer  to  fully charge  the  battery  pack  than  the  standard charging time.  Even  when  the  battery  is  fully  charged,  it will  have  approximately  50%  of  the  power of a fully charged battery at normal operat-ing temperature.
7. If the power lamp does not light immediately after the charger is plugged in, or if after the standard  charging  time  the  charging  lamp does  not  flash  quickly  in  green,  consult  an authorized dealer.
8.  If  a  fully  charged  battery  pack  is  inserted into  the  charger  again,  the  charging  lamp lights up. After several minutes, the charg-ing  lamp  may  flash  quickly  to  indicate  the charging is completed.
