General instructions for the use of grinding wheels
Correct handling - DO always follow instructions for correct storage.
- DO always visually inspect grinding wheels before mounting for possible damage during transport and eliminate damaged ones.
- DO always use a safety guard, which should cover nearly one half of the grinding wheel.
- DO always switch off the power at the supply and/or unplug the machine before changing the wheel.
- DO always use the tools supplied by the machine manufacturer to change the wheel.
- DO always ensure that the spindle speed of the machine is no higher than the operating speed marked on the wheel.
- DO always use the correct wheel mounting flanges for grinding wheels and check that they are undamaged, clean and free of burrs.
- DO always allow newly mounted wheels to run at operating speed with the guard in place for at least one minute before cutting or grinding.
- DO always wear protective gear: safety clothing, dust masks, eye protection (glasses or shield), gloves and ear protection!
- DO have machine speeds checked regularly, especially after maintenance or repair.
- DO always check the tension of the driving belt, where fitted, on a regular basis: belts must be kept tight in order to ensure optimum power transmission.
- DO always secure the workpiece firmly before beginning cutting or grinding.
- DO store portable machines appropriately when not being used, to avoid accidental physical damage to the wheel.
- DO always use portable machines in a comfortable position, where the body is well balanced and the machine is well supported.
- DO always keep the work space around cutting and grinding operations clear. It is very dangerous if an operator slips or falls during grinding, cleaning or polishing operations.
- DO grind at the prescribed angle to the work piece with grinding wheels on an angle grinding machine.
| Incorrect handling
- DON'T store wheels in a damp atmosphere or in extreme temperatures.
- DON'T handle wheels roughly.
- DON'T mount a damaged wheel.
- DON'T EVER exceed the maximum operating speed marked on the wheel.
- DON'T force a wheel onto a machine spindle.
- DON'T use mounting flanges which are incorrect, damaged, dirty or worn out.
- DON'T tighten the mounting nut or locking flange excessively. This can distort the flanges.
- DON'T use a machine which is not in good mechanical condition.
- DON'T EVER grind without protective gear.
- DON'T use wheels without proper ventilation or dust protection equipment.
- DON'T stop the wheel after use by applying pressure to the wheel edge or side. Always switch the machine off and allow the wheel to stop revolving.
- DON'T apply excessive pressure onto the wheel so that the driving motor slows down.
- DON'T drop portable machines or lower to the floor by the cable or air hose. A wheel can be easily cracked by the weight of the machine if it is put down hard. This is a common cause of wheel breakage.
- DON'T use a machine in a position where you do not have full control of the machine and you are not well balanced.
- DON'T grind with a grinding wheel at an angle lower than the prescribed angle.
