Please store in dry and well-ventilated premises without major temperature changes (temperatures between 10-30°C and max. 70% relative humidity).

This will help preserve the physical properties of reinforced resin bonded grinding wheels for up to three years, up to two years for non-reinforced ones.

The storage premises should be as close to the place of use as possible in order to avoid mechanical damage to the wheels during transport, as well as moisture condensation while in transit on colder days.

Please use appropriate stands, shelves, drawers, and boxes for storing various types of grinding wheels.

- Store wide thin-section grinding wheels in a horizontal position on
   a flat surface or on a steel base.
- Place thinner resin bonded cutting-off wheels on a flat surface in
   order to prevent bending.
- Store small grinding wheels on upper shelves or in their original
   packaging.
- Store depressed-center concave grinding wheels one on top of
   the other or in their original packaging, up to a stack height of
   120cm.
- Store grinding wheels and thick-section grinding rings of larger
   dimensions vertically on lower shelves, but transport them
   horizontally.

1. DON'T store wheels in a damp atmosphere or in extreme
    temperatures.
2. DON'T use non-reinforced cutting-off wheels on portable
    machines.
3. DON'T handle wheels roughly.
4. DON'T mount a damaged wheel.
5. DON'T EVER exceed the maximum operating speed marked on
    the wheel.
6. DON'T force a wheel onto a machine spindle.
7. DON'T use mounting flanges which are incorrect, damaged, dirty,
    or worn out.
8. DON'T tighten the mounting nut or locking flange excessively.
    This can distort the flanges.
9. DON'T use blotters for soft mounting of depressed-center
    concave wheels.
10. DON'T use a machine which is not in good mechanical
     condition.
11. DON'T use a machine without a wheel guard.
12. DON'T use wheels without proper ventilation or dust protection
     equipment.
13. DON'T apply side pressure to cutting-off wheels.
14. 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.
15. DON'T allow the wheel to be trapped or pinched in the cut.
16. DON'T apply excessive pressure onto the wheel so that the
     driving motor slows down.
17. DON'T grind on the side of cutting-off wheels.
18. 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.
19. DON'T grind with a depressed-center concave grinding wheel at
     an angle lower than the prescribed angle.
20. DON'T use a machine in a position where you do not have full
     control of the machine and you are not well-balanced.

1. DO always follow instructions for correct storage.
2. DO always visually inspect grinding wheels before mounting for
    possible damage during transport and eliminate damaged ones.
3. DO always use a safety guard, which should cover nearly one
    half of the grinding wheel.
4. DO always use non-reinforced cutting-off wheels on fixed
    stationary machines.
5. DO always switch off the power at the supply and/or unplug the
    machine before changing the wheel.
6. DO always use the tools supplied by the machine manufacturer
    to change the wheel.
7. DO always ensure that the spindle speed of the machine is no
    higher than the operating speed marked on the wheel.
8. DO always use the correct wheel mounting flanges for grinding
    wheels and check that they are undamaged, clean, and free of
    burrs.
9. DO always use blotters between the mounting flanges and the
    wheel sides for soft mounting of flat cutting-off wheels.
10. DO always allow newly mounted wheels to run at operating
     speed with the guard in palce for at least one minute before
     cutting or grinding.
11. DO always wear protective gear: safety clothing, dust masks,
     eye protection (glasses or shield), gloves, and ear protection.
12. DO have machine speeds checked regularly, especially after
     maintenance or repair.
13. 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.
14. DO always secure the workpiece firmly before beginning cutting
     or grinding.
15. DO store portable machines appropriately when not being used,
     to avoid accidental physical damage to the wheel.
16. DO always use portable machines in a comfortable position,
     where the body is well-balanced and the machine is well-
     supported.
17. DO grind at the prescribed angle to the item with depressed-
     center concave grinding wheels on an angle-grinding machine.
18. DO always keep the workspace around cutting and grinding
     operations clear. It is very dangerous if an operator slips or falls
     during cutting or grinding operations.
