A spray nozzle can only perform properly if the entire spray system is operating efficiently.  For peak system performance, all system components such as nozzles, pumps, sensors, hydraulics, and pneumatics, must be accurately controlled.

• Never point a spray gun at another person or yourself, injury can result.
• Use the trigger lock feature when the gun is not in use to avoid accidental discharge.
• Be sure to use correct spray gun for your pressure and flow range to ensure safety and achieve maximum performance.
• Spray guns are rated for optimal flow rates.  Use tips that match - no performance improvements will result from using a tip with a higher capacity than the spray gun.
• Eliminate water hammer and pressure spikes by using an unloader valve.
• Add a swivel hose to ensure easy movement of the spray gun and hose.
• Check and tighten fluid connections if necessary to avoid leaks.
• Proper selection of a spray gun, for your application, will reduce operator fatigue.
