ADDITIONAL SAFETY RULES FOR BENCH GRINDERS
• Ensure that power tools are disconnected from the mains supply when not in use, before
servicing, lubricating or making adjustments and when changing accessories such as
grinding wheels.
• Always use the correct type of grinding wheel for the type of operation to be carried
out and the material being machined. Do not use a grinding wheel as a cutting disc.
• Only use grinding wheels that are in good condition. This will improve grinding and
reduce the load on the machine ensuring a longer life of the grinding wheel and the
machine.
• Never use damaged grinding wheels. Grinding wheels that are cracked, chipped or
worn could shatter causing injury to the operator and bystanders and damage to the
machine.
• Do not use grinding wheels that are larger than specified, only use grinding wheels that
are rated for the machine. The rotational speed shown on the grinding wheel should
always be HIGHER than the rotational speed of the machine.
• Always fit the blotter or paper washers on either side of the grinding wheel if not
already fitted to the grinding wheel.
• When fitting a new wheel ensure blotters are in place, fit concave side of ashers to face
the wheel and tighten the lock nut firmly.
• Do not over tighten (over tightening can crack a grinding wheel).
• Do not attempt to modify the machine or its accessories in any way.
• Do not use excessive force on the grinding wheel. Only use gradual pressure as this will
reduce the wear on the bench grinder and grinding wheels and increase its efficiency
and operating life.
• Use approved safety glasses or goggles, face mask and if being used for an extended
period wear ear defenders.
• Do not start the machine with the work piece in contact with the grinding wheel or
before checking the position of the tool rest.
• Never apply the work piece to the side of the grinding wheel, this could cause the
grinding wheel to shatter.
• Keep guards in place and in good working order. With the machine disconnected from
the mains supply check that the guards are secure and fitted correctly.
• Always keep the tool rest as close to the grinding wheel as possible. The gap between
the tool rest and the grinding wheel should be no more than 2mm.
• Do not attempt to grind objects that are too small to hold safely.
• Do not use the work piece to slow down the grinding wheel once the machine has been
switched off.
