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.
6) 
If  operating  a  power  tool  in  a  damp location  is  unavoidable,  use  a  residual current device (RCD) protected supply.Use of RCD reduces the risk of electrical 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) 
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 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
