[Battery Pack]
For Appropriate Use of Bat­
tery Pack
Li­ion Battery Pack
• For optimum battery life, store the Li-ion bat-tery pack following use without charging it.
• When  charging  the  battery  pack,  confirm  that  the  terminals  on  the  battery  charger 
are  free  of  foreign  substances  such  as  dust 
and  water  etc.  Clean  the  terminals  before 
charging the battery pack if any foreign sub-
stances are found on the terminals. 
  The  life  of  the  battery  pack  terminals  may  be  affected  by  foreign  substances  such  as  dust 
and water etc. during operation.
 
• 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  the  battery  pack,  make  sure  the work place is well ventilated.
• When  the  battery  pack  is  removed  from  the  main  body  of  the  tool,  replace  the  battery 
pack  cover  immediately  in  order  to  prevent 
dust  or  dirt  from  contaminating  the  battery 
terminals and causing a short circuit.
Battery Pack Life
The rechargeable batteries have a limited life. 
If the operation time becomes extremely short 
after recharging, replace the battery pack with 
a new one.
Battery Recycling
ATTENTION:
A  Li-ion  battery  that  is  recyclable  powers 
the product you have purchased.
Please  call  1­800­8­BATTERY   for  infor-
mation on how to recycle this battery.
[Battery Charger]
Charging
Read the operating manual for Panasonic bat-
tery charger for the battery pack before charg-
ing.
Before  charging  the  bat­
tery
Charge  the  battery  at  a  temperature  of  5°C 
(41°F) to 40°C (104°F).
The  battery  pack  cannot  be  charged  at  a  tem-
perature  of  less  than  5°C  (41°F).  If  the  tem-
perature  of  the  battery  pack  is  less  than  5°C 
(41°F),  fi rst  remove  the  battery  pack  from 
the  charger  and  allow  it  to  sit  for  an  hour  in  a 
location where the temperature is 5°C (41°F) or 
warmer. Then charge the battery pack again.
VI. MAINTENANCE
Use  only  a  dry,  soft  cloth  for  wiping  the  unit. 
Do  not  use  a  damp  cloth,  thinner,  benzine,  or 
other volatile solvents for cleaning.

and on, the user is encouraged to try to correct the interference by one or more of the following 
measures:
•

 Reorient or relocate the receiving antenna.
•

  Increase the separation between the equipment and receiver.
•

  Connect  the  equipment  into  an  outlet  on  a  circuit  different  from  that  to  which  the  receiver  is 
connected.
•

  Consult the dealer or an experienced radio/TV technician for help.
FCC  Caution:  To  assume  continued  compliance,  install  and  use  in  accordance  with  provided 
instructions. Use only the battery pack specified in the instructions. Any changes or modifications 
not expressly approved by the party responsible for compliance could void the user’s authority to 
operate this equipment.

RITE GENERALES
 AVERTISSEMENT!  Veuillez  lire  tou­
tes les instructions.
Si les instructions détaillées ci-dessous ne sont 
pas observées, cela peut entraîner une électro-
cution, un incendie et/ou des blessures graves. 
Le terme “outil mécanique” utilisé dans tous les 
avertissements ci-dessous se réfère aux outils 
mécaniques opérés par cordons d'alimentation 
et par batterie (sans fil).
CONSERVEZ  CES  INSTRUC­
TIONS
Sécurité de la zone de travail
1)  Gardez  la  zone  de  travail  propre  et 
bien aérée.
Les endroits encombrés et sombres invi-
tent les accidents.


)  Ne  faites  pas  fonctionner  les  outils 
mécaniques  dans  des  atmosphères 
explosives,  comme  en  présence  de 
liquides  inflammables,  de  gaz  ou  de 
poussière.
Les outils mécaniques génèrent des étin-
celles qui peuvent enflammer la poussiè-
re ou les vapeurs.
3)

  Gardez  les  enfants  et  les  spectateurs 
éloignés  lors  du  fonctionnement  d’un 
outil mécanique.
Les distractions peuvent en faire perdre le 
contrôle.
Sécurité électrique
1)  La  fiche  des  outils  mécaniques  doit 
correspondre  aux  prises  secteur.  Ne 
modifiez la fiche sous aucun prétexte. 
N’utilisez  pas  de  fiche  adaptatrice 
avec  les  outils  mécaniques  mis  à  la 
terre.
Des  fiches  non  modifiées  et  des  prises 
secteur  correspondant  réduisent  les 
risques d’électrocution.


)  Evitez tout contact physique avec les 
surfaces  mises  à  la  terre  telles  que 
t
 uyaux,  radiateurs,  micro ­ondes  et 
réfrigérateurs.
Il y a un risque d’électrocution supplémen-
taire si votre corps est mis à la terre.
3)  N’exposez pas les outils mécaniques à 
la pluie ou à des conditions humides.
D e  l’eau  pénétrant  dans  un  outil  mécani -
que augmente le risque d’électrocution. 4)
  
Ne malmenez pas le cordon. N’utilisez 
jamais  le  cordon  pour  transporter, 
pour  tirer  ou  pour  débrancher  l’outil 
mécanique.  Gardez  le  cordon  éloigné 
de  la  chaleur,  de  l’huile,  d’objets  aux 
b o r d s   c o u p a n t s   o u   d e   p i è c e s   e n 
mouvement.
Les  cordons  endommagés  on  emmêlés 
augmentent le risque d'électrocution.
5)

 
Lors du fonctionnement des outils méca­
niques à l’extérieur, utilisez une rallonge 
adaptée à l’utilisation à l’extérieur.L’utilisation d’un cordon adapté à l’utilisa -
tion à l’extérieur réduit les risques d’élec -
trocution.
Sécurité personnelle
1)  Restez  alerte,  regardez  ce  que  vous 
faites  et  faites  preuve  de  bon  sens 
lorsque  vous  utilisez  un  outil  méca­
nique.  N’ utilisez  pas  un  outil  méca­
nique  alors  que  vous  êtes  fatigué  ou 
sous  les  effets  de  drogue,  d’alcool  ou 
de médicaments.
