Brush life varies, depending on the motor load. Check the brushes after the first 50 hours of use for a new machine or periodically after a new set of brushes has been installed.
After the first check, examine the brushes every 10 hours (approximately) until replacement is necessary.
The brush holders (A) Fig. 42, are located on the DC motor housing opposite each other. Fig. 43, illustrates one of the brushes removed for inspection. When the carbon on either brush (B) Fig. 43 is worn to 3/16” or less, or if the spring is burned or damaged, replace both brushes.
