5. OPERATION
6. MAINTENANCE
 WARNING! Ensure you read, understand and apply safety instructions before use.
5.1. Load the magazine before connecting the airline. To open the magazine, hold the nail gun vertically with one hand, then with the
thumb of your other hand, press the magazine catch upwards and slide the magazine backwards and open with the forefinger of the
same hand. Place a stick of nails into the open magazine chamber ensuring that all nails have their points resting on the bottom of
the chamber.
5.2. Slide the magazine cover shut until it clicks into place behind the catch.
5.3. Before connecting to an air supply, ensure that the trigger catch release slide is NOT depressed. Connect the air line to the nail gun
as described in Section 4.
5.4. The operating trigger is normally locked and cannot be used until the trigger release slide is depressed. This happens automatically
as you position the nail gun.
5.5. The trigger release slide can be seen protruding downwards just in front of the nail outlet (see fig.1). Place the tip of the slide onto the
material to be nailed and press downwards to bring the nail outlet into contact with the surface. As the slide retracts the trigger will
become free.
5.6. Depress the trigger to fire one nail. To fire another nail, release the trigger, reposition the nail gun at the next required nailing point
and depress the trigger again. Repeat as necessary.
5.7. If you need to put the nail gun down during the course of working ensure that the trigger slide catch is not depressed against any object.
5.8. When the work is complete or when you have paused for any length of time, disconnect the nail gun from the air line.

WARNING! Should a blockage occur, disconnect nail gun from the air supply immediately.
5.9. Open the magazine as described above.
5.10. Access the blockage by unclipping the driver guide front-plate (see fig 1) using the release catch provided.
5.11. Remove the nail and any foreign matter found within the driver guide.
5.12. Replace the driver guide front-plate and set the catch.
5.13. Ensure that all parts of the nail gun are secure and correctly positioned, then reconnect the air supply.
 WARNING! Disconnect nail gun from air supply before refilling with nails, servicing or performing maintenance. Replace or repair
damaged parts. Use genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
6.1. Lubricate the air nail gun daily with a few drops of the air tool oil supplied, dripped into the air inlet before use. To re-order air tool oil
use Sealey part No’s. ATO500S or ATO1000S.
6.2. Clean the nail gun after use.
6.3. Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe. Incorrect size or type of hose connectors. To remedy check the
air supply and follow instructions in section 4.
b) Grit or gum deposits in the nail gun may also reduce performance. Flush the nail gun out with gum
solvent oil or an equal mixture of SAE No.10 oil and kerosene. Allow to dry before use.
If you continue to experience problems, contact your local Sealey service agent.
6.4. For a full service contact your local Sealey service agent.
6.5. When not in use, disconnect from air supply, clean nail gun and store in a safe, dry, childproof location.
6.6. On a weekly basis check the security of the hex bolts holding the driver guide plate in place and tighten if necessary (fig.1).
