ately when the Dust protect rubber cap 
is broken to avoid the dust coming in-
side the attachment.
Usage:
• Use with a Chisel bit with SDS-Plus 
type shank in Rotation+Hammer mode, 
for Light duty chiseling (ceramic tile re-
move, scraping sealing material etc.)
  1.  To attach the Chisel attachment
    Remove the Support handle from 
the Rotary hammer. Mount the 
Chisel attachment on the tool.
    Make sure to eliminate a play 
between the attachment and tool. 
Fix the attachment firmly on the 
tool using the butterfly screw.
  2.  Attach the Support handle on the 
Chisel attachment.
  3.  Insert/detach the Chisel bit
    Read instruction manual of the 
Rotary hammer.
  4.  To adjust the blade angle of the

. USAGE SUGGESTION
 1.  If there isn’t enough force pushing down on the bit, the hammer may not be able 
to blow in hammering mode. 
    This is to prevent the hammering mode from operating with no load. Press down 
harder on the bit to engage the hammer and cause it to blow.
    Always be sure to press down with enough force when working.
  2.  In winter or in other situations where the temperature of the unit is low (5°C or be-
low), the blow of the hammering mode may be weaker than normal at the begin-
ning stage.
    This is because the grease becomes stiffer in low temperatures, increasing fric-
tion. 
    If this should happen, operating hammering mode with no load for approximately 
30 seconds and repeat this 3 times. This will restore its blowing power.

. ELECTRICAL PLUG 
INFORMATION
FOR YOUR SAFETY PLEASE READ
THE FOLLOWING TEXT CAREFULLY
This appliance is supplied with a moulded 
three pin mains plug for your safety and 
convenience.
A 5 amp fuse is fi tted in this plug.
Should the fuse need to be replaced please 
ensure that the replacement fuse has a rat-
ing of 5 amp and that it is approved by ASTA 
or BSI to BS1362.
Check for the ASTA mark 
 or the BSI mark 
 on the body of the fuse.
If the plug contains a removable fuse cover 
you must ensure that it is refi tted when the 
fuse is replaced.
If you lose the fuse cover the plug must not 
be used until a replacement cover is ob-
tained.
A replacement fuse cover can be purchased 
from your local Panasonic Dealer.
IF THE FITTED MOULDED PLUG IS UN-
SUITABLE FOR THE SOCKET OUTLET IN 
YOUR HOME THEN THE FUSE SHOULD 
BE REMOVED AND THE PLUG CUT OFF 
AND DISPOSED OF SAFELY.
THERE IS A DANGER OF SEVERE ELEC-
TRICAL SHOCK IF THE CUT OFF PLUG 
IS INSERTED INTO ANY 13 AMP SOCK-
ET.
If a new plug is to be fi tted please observe 
the wiring code as shown below.
If in any doubt please consult a qualifi ed 
electrician.
IMPORTANT: The wires in this mains 
lead are coloured in ac-
cordance with the follow-
ing code:
 Blue: Neutral
 Brown: Live
As the colours of the wire in the mains lead 
of this appliance may not correspond with 
the coloured markings identifying the termi-
nals in your plug, proceed as follows.
The wire which is coloured BLUE must be 
connected to the terminal in the plug which 
is marked with the letter N or coloured 
BLACK.
The wire which is coloured BROWN must be 
connected to the terminal in the plug which is 
marked with the letter L or coloured RED.
Under no circumstances should either of 
these wires be connected to the earth ter-
minal of the three pin plug, marked with the 
letter E or the Earth Symbol 
.
How to replace the fuse: Open the fuse 
compartment with a screwdriver and replace 
the fuse and fuse cover if it is removable.

. Bestimmungsge-
mäße Verwendung 
der Maschine
Dieses Gerät ist ein Bohrhammer für 
das Bohren in Beton. Zusätzlich ver-
fügt das Gerät aber auch über einen 
“Nur-Bohren-Modus”, bei dem kein 
Schlagen erfolgt. Dieser Modus eignet 
sich für das Bohren in Metall und Holz.
Lesen Sie bitte vor der ersten Inbetriebnah-
me dieses Geräts das separate Handbuch 
“Sicherheitsmaßregeln” sorgfältig durch.
. WEITERE WICH-
TIGE 
SICHERHEITS-
REGELN
 1) Verwenden Sie den mit dem 
Werkzeug gelieferten Zusatzgriff 
(Haltegriff). Verlust der Kontrolle 
kann Verletzungen verursachen.
  2)  Denken Sie daran, dass das 
Werkzeug ständig betriebsbereit 
ist, da es nicht an die Steckdose 
angeschlossen werden muss.
 3)  
Halten Sie Elektrowerkzeuge an 
den isolierten Griffflächen, wenn 
Sie eine Arbeit durchführen, 
bei der die Maschine auf ver-
borgene Kabel treffen könnte; 
bei Kontakt mit stromführenden 
Kabeln werden die freiliegenden 
Metallteile der Maschine ebenfalls 
stromführend und der Benutzer er-
leidet einen elektrischen Schlag.
 4) Wenn der Bohrer sich festfrisst, so-
fort den Auslösehebel freigeben, 
da das Akkupack und der Motor bei 
Überlastung der Maschine beschä-
digt werden können. Zum Lösen des 
Bohrers auf Linkslauf schalten.
  5)   Betätigen Sie den Rechts/Linkslauf 
Schalter nicht, wenn der Betriebs-
schalter eingeschaltet ist. Der Akku 
entlädt sich sonst schnell, und das 
Gerät kann beschädigt werden.  6)   Das Gerät nur mit einem trocke-
nen, weichen Lappen abwischen. 
Verwenden Sie zum Reinigen kei-
ne feuchten Lappen oder flüch-
tigen Lösungsmittel wie Farbver-
dünner oder Benzin.
  7)   Stellen Sie den Rechts/Linkslauf 
Schalter zum Lagern oder 
Tragen des Werkzeugs auf die 
Mittelstellung (Schaltersperre).
 8)  
Das Gerät wird überbeansprucht, 
wenn Sie den Betriebsschalter in 
halb eingeschobener Stellung hal-
ten (aktive Drehzahlregulierung) 
und den Motor abwürgen. 
    Hierdurch spricht die Schutzschal-
tung an, die die Drehzahlregulie-
rung außer Funktion setzt. In sol-
chen Fällen den Betriebsschalter 
freigeben und erneut ziehen, damit 
das Gerät wieder normal arbeitet.
  9)   Darauf achten, dass kein Staub in 
das Futter gerät.
 10)   Wegen Verletzungsgefahr bei lau-
fender Maschine keine sich dre-
henden Teile berühren!
 11) 
Die Maschine nicht über längere Zeit 
ununterbrochen laufen lassen, son-
dern von Zeit zu Zeit stoppen, damit 
der Motor sich abkühlen kann.
 12)  Die Maschine nicht fallenlassen!
 13) Tragen Sie einen Gehörschutz. 
Lärmeinwirkung kann zu Gehör-
verlust führen.
 14) 
ACHTUNG! Achten Sie darauf, dass 
Sie das SDS-Futter mit eingespanntem 
Werkzeug nicht versehentlich aufstüt-
zen. Das SDS-Werzeug wird dann im 
SDS-Futter gelöst und fällt nach unten 
aus der Maschine. Dies kann Verlet-
zungen zur Folge haben.

• Verwenden Sie nur die Panasonic-Ak-
kus, die für den Einsatz mit dieser Ak-
ku-Maschine ausgelegt sind.
• Werfen Sie den Akku nicht ins Feuer, 
und setzen Sie ihn auch keiner über-
mäßigen Wärme aus.
• Unterlassen Sie das Einschlagen von 
Nägeln in den Akku sowie Erschüttern, 
Zerlegen oder Abändern des Akkus.
• Achten Sie darauf, dass keine Metall-
gegenstände mit den Kontakten des 
Akkus in Berührung kommen.
• Unterlassen Sie das Tragen oder Auf-
bewahren des Akkus zusammen mit 
Nägeln oder ähnlichen Metallgegen-
ständen im selben Behälter.
• Laden Sie den Akku nicht an einem 
heißen Ort, wie z. B. in der Nähe eines 
Feuers oder in direktem Sonnenlicht. 
Anderenfalls kann der Akku überhit-
zen, Feuer fangen oder explodieren.
• Verwenden Sie nur das zugehörige La-
degerät zum Laden des Akkus. Ande-
renfalls kann der Akku auslaufen, über-
hitzen oder explodieren.
• Nachdem Sie den Akku von der Ma-
schine oder dem Ladegerät abgenom-
men haben, bringen Sie stets die Ak-
kuabdeckung wieder an. Anderen-
falls könnten die Akkukontakte kurz-
geschlossen werden, was zu einem 
Brand führen kann.
