Frequently Asked

From time-to-time, your equipment might need attention before you can get it working properly. Here is a list of helpful answers to some of the most common concerns we receive often. Of course, you can always contact us for an appointment to service your spraying system if it isn’t working well.

My spray gun won’t dispense, what should I do?

First, check to see if you have the safety in the off position. If that isn’t the problem, disassemble the spray gun and clean it thoroughly before putting it back together.

Does the sprayer need to be cleaned after each use?

The ideal recommendation is that the equipment should be flushed each time that it is used. This task helps to minimize paint curing inside the pump

How do I clean the air cap?

Take the cap off and use fresh solvent to soak it for a few minutes. Take a bristle brush and clean away paint and debris from the cap. Use compressed air to dry the cap.

Why should I replace my tips frequently?

Worn-out tips can lead to difficulty achieving even spray patterns. In order to compensate for the irregularity of the tip, you might be tempted to increase the gun speed or fluid pressure, both of which lead to a less attractive result.

My pump is difficult to prime in the morning, is there anything I can do to ease this process?

If you are having difficulty priming on a regular basis you might want to have your pump serviced to make sure that everything is aligned properly. On your own, you can check for loose hose fittings, worn-out hose o-rings, clogged strainers, or a dislodged intake ball.

Does my paint booth need to meet any codes?

Spray booths of all kinds must meet national/international codes and might be subject to local ones provided by your municipality. The booth must meet National Fire Protection Association Chapter 33, NEC, and OSHA 1910 codes.

Does the use of electrostatic equipment offer any benefits that traditional spray guns do not?

Electrostatic equipment is designed to produce a more efficient transfer of product over that delivered by traditional spraying equipment. As a result, solvent emissions are reduced, and the cost of material is decreased considerably.

My air motor on my pump is leaking oil, what should I do?

If oil is leaking from the underside of the air motor, you need to bring it in for servicing. A qualified technician can assess the damage, determining whether you need a rod replacement as well as a new throat packing setup.

The finish I get with my equipment is bumpy and ugly, what am I doing wrong?

This problem can occur for a number of reasons. If the weather is too hot and dry, your fluid could be drying quicker than it should. If you think this is the case, consider using a reducer that operates more slowly. If you are holding the spray gun too closely to the work piece, you can create craters and/or bumps in the finish. Also, if you are using too much material, this is the result that you get – a kind of bumpy-like finish that resembles citrus skin. Make sure that the needle you are using isn’t too large.
