abnomalities before mounting. Make sure it is
fi
rmly clamped and has been properly
mounted. Refer to page 51 of this manual for Depressed Center Wheel Assembly and

5. Test the grinder before using.
Before actually beginning the grinding work, test the grinder by
fi
rst 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 is as follows:
When depressed center wheel is replaced .............................................3 minutes or more
When starting daily work ........................................................................1 minute or more
6. Use only properly rated depressed center wheels.
Use only depressed center wheels rated at 6,600 r/min or more.
Using a depressed center wheel rated less can lead to wheel disintegration during
operation and cause serious bodily injury.

Make sure that the push button is disengaged by
pushing push button two or three times before turning
on the grinder. (
