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.
2) 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.
2)  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.

2)  Be  aware  that  this  tool  is  always  in  an 
operating condition, since it does not have 
to be plugged into an electrical outlet.
3)  Hold  power  tools  by  insulated  grip­
ping  sur  faces  when  performing  an 
operation  where  the  cutting  tool  may 
contact hid  den wiring.
  Contact  with  a  “live”  wire  will  make  ex-
posed  metal  parts  of  the  tool  “live”  and 
shock the operator.
4) If the bit becomes jammed, immediately 
turn  the  trigger  switch  off  to  prevent  an 
overload  which  can  damage  the  battery 
pack  or  motor.  Use  reverse  motion  to

How to Use the Belt Hook 
WARNING!
•  Be  sure  to  attach  the  belt  hook  securely  to 
the main unit with the screw firmly fastened. 
When the belt hook is not firmly attached to 
the main unit, the hook may disconnect and 
the main unit may fall. 
  This may result in an accident or injury.
•  Periodically  check  screw  for  tightness.  If 
found to be loose, tighten firmly.
• 
Be  sure  to  attach  the  belt  hook  firmly  and 
securely  onto  a  waist  belt  or  other  belt.  Pay 
attention  that  the  unit  does  not  slip  off  the 
belt. 
This may result in an accident or injury.
•  When  the  main  unit  is  held  by  the  belt 
hook,  avoid  jumping  or  running  with  it.  
Doing  so  may  cause  the  hook  to  slip  and 
the main unit may fall. 
  This may result in an accident or injury.
• When  the  belt  hook  is  not  used,  be  sure 
to  return  it  to  the  storing  position. The  belt 
hook may catch on something. 
  This may result in an accident or injury.
• 
When the unit is hooked onto the waist belt 
by the belt hook, do not attach driver bits to 
the unit. A sharp edge object, such as a drill 
bit, may cause injury or an accident. 
To Change the Belt Hook 
Location Side
The  belt  hook  can  be  attached  to  either  side 
of the unit.
1.  Removing the hook
  (1) Remove the nut.
  (2) Draw out the hook.
2. Attaching the hook to the other side
