3X-CNW50
4X-CNZ45
5F-CNW65
7F-CNW90
9F-CNW100EPAL.
In this operating manual, these coilnailers are referred to as tackers for
short.
We assume that every user of the tacker is familiar with the use of
pneumatic equipment and the materials employed. Persons without this
know-how must be instructed in the use of the tacker by an experienced
user.
This operating manual is intended for the following persons:
Persons who operate this tacker,

Safety
Observe and follow all the warnings and instructions in this operating manual
and on the tacker when using the tacker. The spare parts list supplied with
the tool forms an integral part of this operating manual.
Intended use
The 3X-CNW50, 5F-CNW65, 7F-CNW90 and 9F-CNW100EPAL tackers are
intended for driving coilnails into wood. The 4X-CNZ45 tacker is intended for
driving coilnails into roofing felt, bitumen shingles, insulating material and
packagings. Use of the tackers with other materials is only permitted after
consultation with the manufacturer. The intended use also includes
compliance with the accident prevent regulations and the statutory
regulations and standards in force at the place of use. Use in any other way
is not considered an intended use and can result in material damage or even
personal injury.
Unauthorised use
An unauthorised use constitutes in particular operation
by persons without the necessary know-how in the use of tackers and
the materials used,
with the safety device bypassed,
of tackers modified without the authorisation of the manufacturer,
using other than original PREBENA coilnails, see page 37,
in the trigger position "repeat firing"
- for work requiring movements over scaffolds, stairs, ladders or
ladder-like constructions,
- for closing boxes or crates or for the attachment of transport locks.
PREBENA WILFRIED BORNEMANN GMBH & CO. KG accepts no liability
for any damage resulting from any such unauthorised use.

Safety
7
Avoid risk of fatal injuries
Never direct the tacker at people, animals or parts of their body.
Only actuate the tacker when the tool nose is pressed against the
workpiece.
Do not allow children to play with packaging films - risk of suffocation.
Ensure that the coilnails are not driven into power cables.
Avoid explosion hazards
Do not use the tacker in areas with an explosion hazard.
Never operate the tacker with oxygen or other explosive gases or gas
mixtures.
Do not expose the compressor to temperatures over 100°C.
Avoid injury risks
Store the tacker out of the reach of children and other unauthorised
persons.
Always disconnect the tacker from the compressed air supply before
transporting.
Wear protective goggles, ear protectors and sturdy working clothes when
working with the tacker.
Hold the tacker in such a way that you cannot be injured by a possible
recoil.
Use the tacker when you are standing with a firm footing.

Function
The 3X-CNW50, 5F-CNW65, 7F-CNW90 and 9F-CNW100EPAL tackers
drive PREBENA coilnails individually into wood and packagings using
compressed air. The 4X-CNZ45 tacker drives PREBENA roofing felt nails
individually into roofing felt and bitumen shingles using compressed air. The
9F-CNW100EPAL tacker is used for manufacturing and repairing
Europallets.
PREBENA compressors are used as the compressed air source. An
overview of the compressors can be found from page 39.
An overview of the coilnails that can be used can be found from page 37.

Preparing the tacker
Unpacking the tacker
Remove the tacker from the packaging.
Remove all packaging materials, such as plastic films, filler material and
the cardboard box.´
WARNING
Do not allow children to play with plastic
packaging films. Risk of suffocation!
Do not allow children to play with plastic packaging films.
Store the packaging materials out of the reach of children.
Save the packaging material for later use.
Keep the transport case for the transport of the tacker.

The tacker may only be transported in the transport case.
Check condition
Warning
Risk of injury when using a damaged tacker
or if accessories are not correctly attached.
Check the condition of the tacker before every use
Always ensure that the tacker is in a safe working condition.
Check in particular the following points:
- The air hose must be undamaged.
- All parts of the tacker and all accessories must be securely attached.
- The safety devices must not be blocked or otherwise impaired in their
function.
- The spring of the firing protection device must not be damaged.
- No parts of the tacker or the accessories may show visible signs of
damage, such as scratches or dents.

Scratches in the paintwork of the housing or magazine are not
"damage".

Preparing the tacker
15
Do not connect a damaged tacker to a compressed air supply.
Have a damaged tacker repaired by qualified personnel before putting it
into operation.
Connect tacker to compressed air supply
The tacker can be connected to a compressor or compressed air system.
Operation with a compressor or compressed air system is only permitted
under the following conditions:
The working pressure of the compressor or compressed air system must
not be more than 10% of the maximum working pressure of the tacker.
Information on the working pressure of the tackers can be found in this
chapter on page.
If the compressed air system has a higher working pressure, a pressure
control valve (pressure reducer) with downline pressure relief valve must
be installed in the compressed air line.
The compressed air must be filtered, dry and oiled with PREBENA
special nailer oil.
An air conditioner must be installed on the coupling side of the outlet
ports for the compressed air line to the tacker. This should comprise
- Filter,
- Water trap and
- Oiler.
If no oiler is installed, the length of the air line to the tacker must not
exceed max. 10 metres. Otherwise pour three to five drops of PREBENA
special nailer oil directly into the air inlet port of the tacker every day
before starting work.
The compressed air system must be able to maintain the working
pressure even with the desired air consumption.
The inside diameter of the air line must be at least 9 mm.
The connection for the tacker must be fitted with a quick coupler with NW
7.2 and with an inside diameter of at least 6.5 mm.

Preparing the tacker
16
CAUTION
Operation on compressed air systems not
satisfying the preconditions described above
can result in damage to the tacker.
Operate the tacker only on suitable compressed
air systems.
Operate the tacker only when it is in a safe
working condition.
Check the condition of the tacker (see page 14).
Pull the plug out of the connection for the compressed air hose.
Inspect the connection for the compressed air hose for foreign matter
and soiling and clean, if necessary.
Set the working pressure at the pressure regulator of the compressor to
5 - 8.3 bar.
WARNING
Inadvertent firing during connection to the
compressed air supply can result in serious or
even fatal injuries.
Never direct the tacker at people or animals.
Empty the magazine before connecting.
CAUTION
Damaged hoses can burst and result in
injuries.
Inspect the compressed air system and tacker
for damage before connection.
Connect the tacker only to a fully functional
compressed air system.
ATTENTION
Damaged hoses can burst and and cause material damage due
to the escaping compressed air.
Inspect the compressed air system and tacker for damage before
connection.
Connect the tacker only to a fully functional compressed air system.
