PRECAUTIONS ON USING BENCH GRINDERS
• Always disconnect power supply cord before servicing or replacing
grinding wheels.
• Replace cracked or damaged grinding wheels immediately.
• Always use safety guards and eye protection shields.
• Ensure tool rests and eye protection shields are properly adjusted.
• Do not over tighten wheel nut.
• Maintain a maximum distance of 1/8" (3mm) between grinding wheel
and tool rests as the grinding wheel wears and diameter decreases.
• Use only grinding wheels with a RPM rating equal to or greater than
RPM of the grinder motor.
• Ensure grinding wheels rotate freely before turning power on.
• Do not stand in front of grinder when turning power on. Always stand
to the side until grinder comes up to full speed to make sure it is
operating safely.
• Always inspect and ring test a new grinding wheel before mounting
and allow the new wheel to rotate freely for at least one minute
before using grinder. The grinding wheel can be ring tested by
tapping the wheel gently with a nonmetallic object such as a
screwdriver handle or plastic hammer. The wheel is in good
condition If you hear a ring. The wheel is cracked or defective if the
sound is more of a thud or dead sound.
• Do not operate the grinder with the wheel guards off.
• Do not grind on the side of the grinding wheel or use the wheel for
cutting purposes.
• Do not overload the grinder.
• Use a wheel dresser to remove imperfections and keep the grinding
wheel in good safe condition.
• Maintain a maximum distance of ¼" (6mm) between the grinding
wheel and upper tongue guard as the grinding wheel wears and
