PREPARING THE BACBR 14.4 V RIVETER
Fit the mandrel collecting container (E) by turning
to the right. Push the battery (F) into the foot of the
riveter from the front and ensure that the battery
(F) is properly engaged. Press the trigger (I) and
hold it depressed. Fit the appropriate nose piece
(A) for the rivet you wish to set using the combi-
nation wrench supplied. After changing the nose
piece, release the trigger.
WORKING WITH THE RIVETER
RIVETING
Insert the mandrel of the rivet into the nose piece
(A). Now insert the rivet into the parts to be riveted.
For a good riveting result, ensure that the parts and
the head of the rivet are resting on one another
without a gap. Press the trigger until the mandrel
is sheared. Hold the riveter so that the mandrel
collecting container is facing downwards to ensure
that the sheared mandrel drops into the mandrel
collecting container.
When working with cover cap, hold the riveter with
the nose piece (A) facing downwards after each
set rivet to ensure that the sheared mandrel drops
out of the riveter to the front. Do not use fixed or
retainer nose pieces together with the cover cap.
This would result in damage to the riveter!
MALFUNCTION
If rivets are used beyond the specified performance
capability of the riveter, the riveter stops and the
red LED (D) comes on. Wait until the LED (D) goes
out and press the trigger briefly again. The tool
then moves to its starting position again.
When the battery (F) is discharged, the riveter is
protected by a protection circuit. The riveter com-
pletes the cycle and then stops. The LED (D) lights
up yellow. Replace the discharged battery with a
charged battery (F). The yellow LED (D) goes out
and you can continue to work.
STUD HOLDER
The riveter is equipped with a safety switch, the
“stud holder”, and thus conforms also to the Ma-
chinery Directive. This prevents the riveter being
used without mandrel collecting container (E).
Never operate the riveter without mandrel collect-
ing container (E) or cover cap (J). Never bypass
the safety switch. If you have to work in confined
spaces, the cover cap (J) can be fitted instead of
the mandrel collecting container (E). When working
with cover cap (J), hold the riveter with the nose
piece (A) facing downwards after each set rivet
to ensure that the sheared mandrel drops out of
the riveter to the front. Do not use fixed or retainer
nose pieces together with the cover cap (J). This
would result in damage to the riveter!
HANGER CLIP
If you wish to use the riveter on a balancer, you
can attach the hanger clip supplied (K) to the two
bores (C) provided. Take care not to stretch the
hanger clip (K) too far apart so that it does not lose
its tension. Check that the hanger clip (K) is fitted
securely before using the riveter.
BELT CLIP
Attach the belt clip (O) to the foot of the riveter us-
ing the screw (M). A corresponding thread and two
slots (L) are recessed in the foot of the housing on
both sides of the riveter. Check at regular intervals
that the clip (O) is still securely attached, otherwise
retighten the screw (M).
MAINTENANCE AND SERVICE
SERVICING AND CHANGING THE CLAMP-
ING JAWS
Depending on the mandrel material, shear force
and surface finish, the clamping jaws have to be
cleaned and replaced at regular intervals.
I Loosen and remove front sleeve (B) using a
SW 27 comination wrench.
II Loosen and remove clamping sleeve (1) from
adapter (3) using two SW 17 combination
wrenches and remove the 3-piece clamping
jaws (2) from clamping sleeve (1). Clean clam-
ping jaws (2) and inspect for wear. Replace
clamping jaws (2), if necessary.
III Clean the inside and outside of clamping slee-
ve (1). Grease the inside of clamping sleeve
(1) lightly with graphite grease using a brush
(4).
IV Place clamping jaws (2) into clamping sleeve
(1).
Install clamping sleeve (1) with clamping jaws
(2) on adapter (3) again and finally fit front
sleeve (B).
Important: Tighten the clamping sleeve using two
