Accessory
Masonry Wheel*

Metal Cutting Wheel*
(Aluminum Oxide)
*Internally Reinforced
Cleaning
Blowing dust and grit out of the main housing by means of an air
hose is recommended and may be done as often as dirt is seen
collecting in and around the air vents. The motor should be running
while air is being blown into the vents.
Lubrication
Except for the needle roller bearings used at the upper end of the
spindle, closed-type, grease-sealed ball bearings are used
throughout. These bearings have sufficient lubrication packed in
them at the factory to last the life of the bearing. The needle bearings
mentioned above receive their lubrication from the grease in the gear
case.
Gears should be relubricated every 60 to 90 days, depending upon
use. This lubrication should only be attempted by experienced power
tool repair technicians like the mechanics at B&D service centers.
Brushes
Inspect carbon brushes often. Replace when brushes are worn down
to the identifying groove or when spring exerts insufficient pressure
to hold brush against commutator. Keep brushes clean and sliding
free in brass inserts.
