Battery Tool Use and Care
1)  Ensure  the  switch  is  in  the  off 
position  before  inserting battery 
pack.
  Inserting  battery  pack  into  power 
tools that have the switch on invites 
accidents.
2)  Recharge  only  with  the  charger 
specied by the manufacturer.
  A charger that is suitable for one type 
of battery pack may create a risk of 
fire when used with another battery 
pack.
3)  U s e   p o w e r   t o o l s   o n l y   w i t h 
specifically  designated  battery 
packs.
  Use of any other battery packs may 
create a risk of injury and re.
4)  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 together 
may cause burns, or a re.
5)  Under  abusive  conditions,  liquid 
may be ejected from battery; avoid 
contact.  If  contact  accidentally 
occurs, flush with water. If liquid 
contacts eyes,  additionally  seek 
medical help.
  Liquid ejected from the battery may 
cause irritation or burns.
Service
1)  Have your power tool serviced by a 
qualified repair person using only 
identical replacement parts.
  This will ensure that the safety of 
power tool is maintained.
III.   SPECIFIC SAFETY 
RULES
1)  Wear ear protectors. Exposure to 
noise can cause hearing loss.
2)  Use auxiliary handles supplied with 
the tool. Loss of control can cause 
personal injury.
3)  Hold  power  tools  by  insulated 
gripping surfaces when performing 
an operation where the cutting tool 
may contact hidden wiring.
  Contact with  a  “live” wire will make 
exposed metal parts of the tool “live” 
and shock the operator.
4)  Be aware that this tool is always in an 
operating condition, since it does not 
have to be plugged into an electrical 
outlet.
5)  I f   t h e   b i t   b e c o m e s   j a m m e d , 
immediately  turn the trigger  switch 
off to prevent an overload which can 
damage  the  battery pack  or motor. 
Use reverse motion to loosen jammed 
bits.
6)  Do not operate the Forward/Reverse 
lever when the trigger switch  is on. 
The battery will discharge rapidly and 
damage to the unit may occur.
7)  When  storing or  carrying the  tool, 
set the Forward/Reverse lever to the 
center position (switch lock).
8)  Do not strain the tool by holding the 
speed control trigger halfway (speed 
control mode) so that the motor stops. 
The protection circuit will activate and 
may prevent speed control operation. 
If this happens, release the speed 
control trigger and squeeze again for 
normal operation.
9)  Be careful not to get dust inside the 
chuck.
10)  Do not  touch  the  rotating  parts  to 
avoid injury.
11)  Do not use the tool continuously for a 
long period of time. Stop using the tool 
from time to time to avoid temperature 
rise and heat overload of the motor.
12)  Do not drop the tool.
13)  Wear dust mask, if the work causes 
dust.
14)  During  charging,  the  charger  may 
become slightly warm. This is normal. 
Do NOT charge the battery for a long 
period.
