Part number 01694 is a motor brush used to conduct electrical current between stationary wires and the rotating commutator in compatible electric motors. This brush is a wear item that requires periodic replacement to maintain motor performance. It is compatible with SprayTech Airless EP2300 SE; SprayTech Airless EP2300; and SprayTech Airless EP2400 models. Replacing worn motor brushes restores motor power and prevents damage to the commutator.

The 01694 motor brush is a consumable electrical component used in the universal motors of compatible SprayTech Airless sprayer models. It is specifically designed for use with SprayTech Airless EP2300 SE, EP2300, and EP2400 units. In an electric motor, brushes are spring-loaded carbon blocks that press against the spinning commutator. They conduct electrical current from the stationary power supply to the rotating armature windings, creating the magnetic fields that cause the motor to turn. Over time, these brushes wear down due to friction. As they wear, the spring pressure decreases, and the contact area can become poor, leading to arcing, sparking, loss of power, and eventual motor failure. Regular inspection and replacement of motor brushes is a key maintenance task. Symptoms of worn brushes include the motor running slower than usual, loss of power under load, excessive sparking visible through motor vents, a burning smell, or the motor failing to start. Replacing worn brushes with this genuine part restores proper electrical contact and motor performance. It is crucial to replace brushes in sets to ensure even wear and proper commutator contact. When replacing, it is also a good practice to inspect the commutator for signs of wear or damage and to clean any carbon dust from the motor interior. Using the correct replacement brushes ensures the motor operates efficiently and reliably, extending its service life.
