(g) Read the instruction manual for the machine.
Before use check machine and abrasive disc
(a) Make sure machine guards are securely fitted and in the correct position.Check guards for faults.
(b) Check the diameter of the disc is correct for the machine being used and that the RPM marked on the disc is higher than the maximum RPM on the rating plate of the machine
Before fitting disc to the machine
(a) Follow the instruction on the disc and on the packaging.
(b) The mounting flange should be clean,free from distortion of burrs and not damaged in any way.They should be a matching pair.
(c) Make sure top flange is in the correct position for the abrasive disc being used.The top flange can be used either way up depending on the thickness of the disc.
(d) Use mounting blotters if supplied.

(c) Do not start the machine in the workpiece.
(d) After switching on the machine allow a minimum of 30 seconds for the machine to reach full operating speed.Conduct a trial run first.
(e) Do not force the machine in the workpiece.Let the machine do the work.
(f) Always hold machine firmly and support workpiece.
(g) After switching machine off make sure all rotation has stopped before putting machine down.

Made sure all of these are of a high standard.Your safety will depend on them. Avoid breathing in the dust that is generated.Maintain dust levels below the Threshold Limit Value for nuisance dust as classified by OSHA.
Cut-off and Grinding disc Requirements
(a) Hold machine firmly.
(b) Secure work piece tigntly.
(c) Avoid side pressure when cutting.
(d) Do not use cutting disc for grinding.
(e) When grinding approach workpiece at correct angle.
(f) When cutting always cut in a straight line.Do not try and cut curves.
(g) Make sure guard is in correct position.
(h) Make sure abrasive discs are mounted correctly and are tightly held.
(i) Make sure the set of flanges used are free form damage and are the correct matching set for the machine being used.
(j) After switching off machine make sure the rotation has stopped before putting machine down.
