Why won't my Graco T-Max 405 A Paint Sprayer motor operate?

If the Graco Paint Sprayer motor won't operate, first, slowly increase the pressure setting to see if the motor starts. Also, check the electrical supply to ensure the meter reads 210–255 Vac for 220–240 Vac models, or 85–130 Vac for 100–120 Vac models. Reset the building circuit breaker or replace the building fuse, and try another outlet.
