5. OperatiOn
Warning! ensure you read, understand and apply safety instructions before use.
5.1.
load the magazine before connecting the air line. to open the magazine, hold the nail gun body with the left hand, then with your
other hand, press the magazine latch lever and slide the magazine fully open. Place a "strip" of nails into the open magazine chamber,
ensuring that all the 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 safety slide is not depressed. See the 6mm safety dimension infig.1.
5.4.
connect the air line to the nail gun as described in section 4.
5.5.
the operating trigger is normally inoperable and cannot be used until the trigger safety slide is depressed. this happens automatically
as you position and offer the nail gun on to the timber work piece.
5.6.
the trigger release slide can be seen protruding downwards just in front of the nail outlet (see fig.3). Place the tip of the slide onto the
timber work piece to be nailed and press downwards to bring the nail outlet into contact with the surface. As the slide retracts the trigger
will become operational. never depress the safety slide projection with your finger.
5.7.
depress the trigger and release to fire one nail. to fire another nail in quick succession keep the trigger depressed, reposition the nail
gun at the next required nailing point and offer the nail gun on to the timber work piece. repeat as necessary.
5.8.
if you need to put the nail gun down during the course of working, ensure that the trigger safety slide is not depressed against any
object closing the 6mm safety gap in fig.1. this would enable the trigger and possible accidental firing.
5.9.
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 the nail gun from the air supply immediately. see trouble shooting 6.2.
