5. AIR SUPPlY
5.1. Air Supply
(Recommended hook-up procedure is shown in fig.1).
5.2. ensure the gun air valve (trigger) is in the off position before connecting to the air supply.
WARNING! ensure the air supply is clean and does not exceed 90psi while operating the spray gun. Too high an air pressure will
shorten the product life and may be dangerous causing damage or personal injury.
5.3. drain the air supply tank daily. Water in the air line will ruin the paint finish and damage the spray gun.
5.4. Clean air inlet filter weekly.
5.5. 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.
5.6. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
5.7. Couplings
5.7.1. Vibration may cause failure if a quick change coupling is connected directly to the spray gun. To overcome this, connect a leader hose
tothespraygun.Aquickchangecouplingmaythenbeusedtoconnecttheleaderhosetotheairlinerecoilhose.Seeg.1&2.
