4.  PRePARATION

 

‰

  

WARNING!

 ensure the air supply is clean, dry and between 60 - 116psi while operating the nail gun. Too high an air pressure and/   

  or unclean air will shorten the product life due to excessive wear, and may be dangerous causing damage and/or personal injury.

4.1. 

  

AIR SUPPLY

 

4.1.1.   

ensure the nail gun trigger release slide is not depressed when connecting to the air supply. A gap of approximately 6mm between gun  

 

housing and catch will be evident (fig.2).

4.1.2.   

You will require an air pressure of between 60 - 100psi. 

4.1.3.   

drain your compressor air tank of water daily. Water in the air line will damage the nail gun. 

4.1.4.   

Clean the compressor air inlet filter weekly. Recommended hook-up procedure is shown in fig.1.

4.1.5.   

line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be  

 

1/4” I.d. and fittings must have the same inside dimensions.

4.1.6.   

Keep the hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.

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.

5.1.1.   

Slide the magazine cover shut until it clicks into place behind the catch. 

5.1.2.   

Before connecting to an air supply, ensure that the trigger safety slide is not

 depressed. See the 6mm safety dimension in fig.2.

5.1.3.   

Connect the air line to the nail gun as described in Section 4.

5.1.4.   

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.

5.1.5.   

The trigger release slide can be seen protruding downwards just in front of the nail outlet (see fig.3). 

5.2.    

SINGLe  ACTUATION  MeCHANISM

5.2.1. 

  

For single actuation, press the safety slide against the work piece. Pull the trigger to fire the fixing. Once fired it is not possible to fire  

 

again until the trigger is released and pressed again.

5.3.    

“fIRe ON CONTACT” ACTUATION MeCHANISM

5.3.1.   

For this method of operation, press the Safety slide against the work piece and pull the trigger. If the trigger is held ‘on’, each time the  

 

safety slide is pressed against the work-piece a fixing will be fired.

5.4. 

 

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.2. This would enable the trigger and possible accidental firing.

5.5. 

  

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 (Section 6).
