Crack the ergonomics code – Spray Gun Test

Industrial finishing experts agree that atomisation and transfer efficiency are important spray gun features. Yet, as it becomes more difficult for manufacturers to find and keep skilled painters, the importance of operator comfort cannot be under-estimated.

Many painters suffer costly muscle strain or stiffness and repetitive-motion injuries that could be prevented with proper spray gun ergonomics. For example, annual workers compensation claims for injuries like carpal tunnel syndrome can easily cost more than $30,000.

Poor spray gun ergonomics not only cost companies money in claims, but also compromise performance and quality. To remedy this, paint line managers are taking steps to make sure operators can comfortably use their most important tool: their ergonomical spray gun.

When searching for your next manual spray gun, put yourself in your painter’s shoes. Better yet, involve your paint booth team or paint line operators in spray gun test and selection.

Ergonomic, lightweight guns with an easy trigger pull often come up as popular choices. In other words, spray guns that fit such criteria help painters perform well for a long time without injury.

To ensure good spray gun ergonomics and safety, Graco engineers consulted painters while designing PerformAA air assist ergonomical spray guns. That is why the manual spray guns have these features:

• an ultra-light trigger pull that helps reduce fatigue and muscle stress
• a low profile swivel the moves the hose with the operator, preventing tripping and injury
• a handle that fits comfortably in any sized hand
• a finger rest that allows the operator to balance the gun while spraying

PerformAA is just one example of a conventional paint spray gun designed with operator comfort in mind. There are many – conventional and electrostatic – options to choose from.

To make sure you are selecting the right ergonomical spray gun for your painters, ask your finishing equipment distributor for product demonstrations. Bring in a variety of applicators for your paint booth team to try.

Whenever possible, demo each spray gun for an entire shift, if not more. Watch how each painter holds the gun, switches hands, even flips the gun to get at different angles.

After each painter gets used to the gun, evaluate the finish quality, asking questions like “Do you think this spray gun helped you do your job well or better?”

Finding out – and purchasing – their preference can positively affect your bottom line in many ways. A more comfortable work environment not only prevents injury (and costly claims), it can also lead to better productivity and job satisfaction.
