OPERATING THE BENCH GRINDER
The Bench Grinder is designed for hand held
grinding, sharpening, and cleaning
operations.
ALWAYS WEAR EYE PROTECTION! Hot
sparks are produced during grinding
operations. Sharpening and removal of metal
can be done on the
right side of the Bench Grinder using the
grinding wheel. Cleaning of metal surfaces
can be done using the wire wheel on the left
side of the Bench Grinder.
