Abstract: An integrated system and method are provided in an electrically powered airless paint spray unit for thermally monitoring the heat generating elements of the spray unit and provide thermal protection for the spray unit and the monitored heat generating elements. The temperatures of various heat generating elements of the paint spray unit are measured and directed to the motor controller of the electric motor of the unit the microprocessor of which is programmed to adjust the power level to the motor in response to excessive temperature readings of the monitored elements or shut off power to the motor in the event any of the temperature readings are greater than a maximum temperature assigned to the monitored element.

Abstract: There is provided a turret member for a reversible airless spray tip unit having an easily readable identification device or indicia for the particular turret member imprinted on a tag or label attached to a securing device or attaching ring secured to the handle of the turret member. A plurality of turret members are carried on a keychain by their attachment rings for their ease of accessibility to the operator.
