LUBRICATION
All of the bearings in this product are lubricated with a
sufficient amount of high grade lubricant for the life of the
unit under normal operating conditions. Therefore, no further
lubrication is required.

placement is required:
 Unplug the saw.
 Remove brush cap with a screwdriver. Brush assembly is
spring loaded and will pop out when you remove brush
cap.
 Remove brush assembly.
 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.
 Make sure brush cap is oriented correctly (straight) and
replace.
 Tighten brush cap securely. Do not overtighten.
