8. Test the grinder before using.

Before actually beginning the grinding work, test the grinder by first clearing the

area of all other personnel. Make sure the wheel guard is in place and that you

are wearing eye protection. Turn the grinder "on" and make sure the grinder runs

smoothly and shows no abnormalities.

Duration of the trial run isas follows:

When depressed center wheel is replaced .................. 3 minutes or more

When starting daily work .......................................... 1 minute or more

9. Use only properly rated depressed center wheels.

Use only depressed center wheels rated at 12,300 RPM or more.

Using a depressed center wheel rated less can lead to wheel disintegration dur-

ing operation and cause serious bodily injury.

10. Check the push button.

Make sure that the push button is disengaged by pushing push button two or

three times before turning on the grinder.(Fig.3)

Use light grinding pressure.

There is no need to press hard when grinding. Usually the grinder's own weight is

sufficient for the surface to be ground.

ground. Heavy pressure can result in wheel breakage and

serious injury, it can also damage the surface being ground

or damage the grinder's motor.

Grind only with the wheel's edge by lifting the grinder 15to 30, as shown in

Fig. 2.

Use only the edge of the depressed center wheel.
