The bench grinder is a very dangerous machine, though it is simple. Please note the following Safety Advice.

(1) In the grinding process, the fingers are sometimes near the rotating grindstone so take care not to come into contact with the grindstone. The material being ground can become hot to the touch and it is advisable to cool the part in a coolant solution, particularly if removing large amounts of material. Resist the urge to use gloves as gloves can easily be caught by the rotating grindstone resulting in server injury.

(2) When grinding small parts, extra care must be taken as such parts can be "grabbed" by the grins stone and projected out of the grinder at high speeds resulting in severe injury being sustained ALWAYS USE EYE PROTECTION WHEN GRINDING.

(3) Generally, the bench grinder is used for grinding steel however, if grinding aluminium, copper or other alloys, the grindstone can become blocked and this leads to inefficient grinding and overheating.

(4) You should periodically inspect the grindstone for cracks or chips and re-dress the stone or replace as required. ENSURE YOU REMOVE THE PLUG FROM THE SOCKET BEFORE THE INSPECTION TO PREVENT ACCIDENTAL STARTING.
