BE SURE TOOL IS UNPLUGGED BEFORE INSPECTING BRUSHES. Brushes should be regularly inspected for wear. To inspect brushes, unscrew the two end cap screws (A) and remove end cap (B). To remove each brush, (C) first unplug the shunt wire terminal connection. Then carefully back the brush spring (D) out of the brush box and remove brush. Brushes should slide freely in brush box. If brushes are worn down to .3” (8mm) (see Figure 17) they should be replaced. To reinstall each brush carefully back the spring out of the brush box, insert the brush and return the spring making sure it is pressing on the brush and not touching the brush box. Reconnect shunt wire terminal, then replace the end cap and two screws.
