Operation

Before using the tool for the first time
Insert plug-in nipple (12).

Connect to compressed air line
Empty the magazine (15) to prevent fasteners from being ejected when connecting. (If, as a result of repair, maintenance work or transport, interior parts of the stapler gun are not in initial position).
Only connect to compressed air lines after you have ensured that it is not possible to exceed the permissible operating pressure by more than 10% (e.g. using pressure reducers).
Only use quick-action couplings. Make the connection such that the unlockable plug-in nipple is fitted on the tool so that there is no more compressed air in the tool after disconnection.
To benefit from the air tool’s full performance, always use compressed air hoses with an inner diameter of at least 9 mm. Tool performance can be significantly impaired if the inner diameter is too small.
Caution. The compressed air line must not contain any water condensation.
Caution. To preserve and extend the service life of this tool, you must ensure that it is regularly maintained with the pneumatic oil lubricator. You can do this as follows:

• Use oiled compressed air by fitting an oil-fog lubricator.
• Without an oil-fog lubricator: manually apply oil every day via the compressed air connection. Use approx. 3-5 drops of pneumatic oil lubricator for each 15 minutes of continuous operation.

If the tool has not been in use for several days, you should manually apply about 5 drops of pneumatic oil lubricator into the compressed air connection.

Filling the magazine
To fill the magazine (15), hold the device so that the opening (2) is not directed at your own body or other persons.
To fill the magazine (15), hold the device so that the opening (2) is not directed at your own body or other persons.
See illustration in the operating instructions.

• Actuate the locking lever (13) (depending on features) and then…
• pull back the magazine slider (14).
• Insert fasteners that are suitable for the tool (see Section 8. and 11.) in the magazine.
• Push in magazine slider (14) (until it engages at locking lever (13) (depending on features)).

Setting / using the air tool
Caution. Avoid empty shots – do not actuate with empty magazine.

1. Turn the exhaust air aperture (6) (depending on features) into the desired position.

2. DKG 114/65: select operating mode sequential actuation or contact actuation. To do this, press in switch (8) from the right side and turn on the left side. (For explanation, see Section 11.)

3. For sensitive workpiece surfaces, fit the protective cap (1).

4. Connect the air tool to the compressed air supply (see Section 6.2).

5. Fill magazine (15) (see Section 6.3).

6. Set the air pressure initially to the smallest value for the recommended operating pressure.

7. Press the mouth (2) of the stapler onto the workpiece and actuate the trigger (9) (see Section 6.5).

8. Increase or reduce operating pressure in steps of 0.5 bar until the desired fastening result is achieved.
   The stapler should be operated with lowest possible operating pressure. (This saves energy, reduces the noise level and wear)
   Ensure that the maximum operating pressure is not exceeded.

9. For fine adjustment, the insertion depth can be adjusted at the insertion depth control (7) (depending on features).

10. If fasteners become jammed, disconnect the tool from the compressed air supply, actuate the lever (4) to open the service port (9) and remove the defective fastener.

11. Before long pauses or at the end of work, disconnect the tool from the compressed air source and empty the magazine.

Actuating the air tool
Important: DKG 80/16, DPN 25 work without a trigger safety lock. Use your middle finger to unlock the tool at the unlocking lever (16); only then can the shot be triggered with the forefinger on the trigger (9).
The other stapler guns (all except for DKG 80/ 16, DPN 25) are equipped with a trigger safety lock (3) and identified by an equilateral triangle on its tip. The trigger safety lock only permits work when the lock (3) is pressed on the fastening point and the trigger (9) is actuated. These tools must only be used with a functioning trigger safety catch.
If a tool is defective or not functioning perfectly, disconnect it from the compressed air source immediately and forward it to a specialist for inspection.

Care and Maintenance

Danger! Disconnect the compressed air connection and empty the magazine before carrying out any work on the tool.

Technical Specifications

Explanatory notes on the specifications on Page 3. Subject to change in line with technological advances.

S1 = Sequential actuation
S2 = Sequential actuation with safety sequence
C = Contact actuation

Explanation:
Sequential actuation: The trigger (9) must be actuated for every fastening operation. For each additional fastening operation, the trigger first has to be moved back to initial position.
Sequential actuation with safety sequence: For each fastening operation, the trigger (9) and trigger safety lock (3) must be actuated so that a single fastening operation is initiated via  the trigger after the opening of the tool is placed on the fastening point. Additional fastening operations can only be actuated if the trigger and trigger safety lock are in initial position.
Contact actuation: For every fastening operation, the trigger (9) and trigger safety lock (3) must be actuated, whereby the order of actuation is not defined. For subsequent fastening operations, it is sufficient either if the trigger remains actuated and the trigger safety lock is actuated, or vice versa.
