ATBGU/8 Bench Grinder
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 washers 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 3mm.
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.
WARNING!
Do not use bench grinders in areas where there is a risk of explosion or fire from combustible
materials, flammable liquids, paint, varnish, petrol etc. flammable gases and dust of an explosive
nature. As a precaution it is recommended that you consult an expert on a suitable fire
extinguisher and its use.The metal particles (sparks) which are produced during grinding are hot
and could ignite any combustible material in the vicinity of the operation.
