(2) Dressing the wheel
After attaching a wheel, adjust de
fl
ection of the wheel center by using a dresser.
If the wheel center is eccentric, not only precise
fi
nishing cannot be achieved but also
grinder vibration increases, lowering grinder accuracy and durability.
A clogged or worn wheel will soil the
fi
nishing surface or lower grinding e
ffi
ciency.
Occasionally dress the wheel by applying the dresser.
(3) Thorougly check that the wheel is free of cracks, splits and other abnomalities before
mounting. Make sure it is
fi
rmly clamped and has been properly mounted.
(4) Test the die grinder before using.
Before actually beginning the grinding work, test the die grinder by
fi
rst clearing the area of
all other personnel. Make sure you are wearing eye protection. Turn the die grinder “on”,
and make sure the die 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
(5) Use only properly rated wheels.
Use only depressed center wheels rated at
29000 /min or more.
Using a wheel rated less can lead to wheel disintegration during operation and cause
serious bodily injury.
CAUTION
The revolving wheel will create air turbulence.
Do no lay the die grinder down in areas of dust or dirt until it has come to a
complete stop.

2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should
any of the screws be loose, retighten them immediately. Failure to do so could result in
