MAINTENANCE
Cleaning
Blowing dust and grit out of the motor housing using compressed air is a nec­
essary regular maintenance procedure. Dust and grit containing metal parti­
cles often accumulate on interior surfaces and could create an electrical shock
hazard if not frequently cleaned out. ALWAYS WEAR SAFETY GLASSES.
CAUTION: Never use solvents or other harsh chemicals for cleaning the non-
metallic parts of the tool. Use clean, dry rag only.
Lubrication
B&D tools are properly lubricated at the factory and are ready for use. Tools
should be relubricated regularly every sixty days to six months, depending on
usage. (Tools used constantly on production or heavy-duty jobs and tools
exposed to heat may require more frequent lubrication.) This lubrication
should only be attempted by trained power tool repairpersons, such as those
at B&D service centers or in other qualified service organizations.
Motor Brushes
Be sure tool is turned off and disconnected before inspecting brushes. Carbon
brushes should be regularly inspected for wear. To inspect brushes, unscrew
the plastic brush inspection caps (located in the sides of the motor housing)
and the spring and brush assemblies may be withdrawn from the tool.
Keep brushes clean and sliding freely in their guides. Carbon brushes have
varying symbols stamped into them, and if the brush is worn down to the line
closest to the spring, they must be replaced. New brush assemblies are avail­
able at B&D service centers.
