APPLICATIONS
This product has been designed only for the purposes
listed below:
• Sharpening drill bits
• Sharpening lawn mower blades
• Sharpening chisels and flat screwdrivers
BASIC OPERATION
To be efficient and work as designed, your tools should
be kept sharp. Dull tools can and will cause accidents.
Bench grinders are ideal for sharpening tools such as chisels,
planer blades, scissors, etc., and for removing rust or corro-
sion. Grinders remove material rapidly so pressure is the key
to efficient grinding.
The proper way to sharpen a tool and avoid overheating is:
• Keep the object in constant motion, moving
it at an even pace.
• Never force a tool against the grinding wheel.
• Keep the tool cool by using a pan of water.
• The grinding wheel should rotate "into"
the object being sharpened.
