MAINTENANCE
replacing brushes
See Figure 17.
This product has externally accessible brush assemblies that should be periodically checked for wear.
Unplug the tool.
With a flat head screwdriver, remove the brush caps. The brush assembly is spring loaded and will pop out when you remove the brush cap.
Remove the brush assembly (brush and spring). Check for wear. Replace both brushes when either has less than 1/4 in. length of carbon remaining. Do not replace one side without replacing the other.
Reassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube.
Replace brush cap and tighten securely. Do not over- tighten.
