Air Supply

3.1.1

Ensure the trigger is not depressed before connecting to the air supply.

3.1.2. An air pressure of no more than 90psi and an air volume of 10cfm will be required.

3.1.3.

p

WARNING! 

Ensure air supply does not exceed 90psi. Too high a pressure will shorten the product life and may 

be dangerous, causing damage and/or personal injury.

3.1.4. Drain air supply tank daily. Water in the air line will damage the gun and will invalidate your warranty.

3.1.5. Clean air inlet filter screen weekly. For recommended hook-up, see figs.1& 2. 

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

fittings diameter should be 10mm I.D.

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

3.2.  

Couplings.

3.2.1.    Vibration may cause failure if a quick change coupling is connected directly to the wrench. To overcome this, connect a 

leader hose to the wrench. A quick change coupling may then

be used to connect the leader hose to the air line recoil hose. See figs. 1& 2.
