About Your Tool
The word “attachment” in the sentences below refers to
mounted wheels and rotary burrs.
WARNING
●
Do not use an attachment with rated revolution
speed (the number of revolutions marked on the
package) less than the actual revolution speed
of the Die Grinder.
●
Inspect an attachment for chips or cracks prior
to mounting.
Do not use an attachment that is chipped or cracked
or otherwise damaged. Do not use an attachment
that has been soaked in water or any other liquid.

Make certain the diameter of the attachment
mandrel suits the chuck.
Fasten the attachment securely. Use a genuine
chuck sleeve.
●
After mounting a new attachment, hold the Die
Grinder under a steel workbench or inside a
casting and run it for at least one minute.
Make certain no one is within over the rotating
surface. If the attachment is defective, improperly
mounted or the wrong size and speed, this is the
time it will usually fail.

After a Die Grinder repaired and is issued for
use, check the free speed with no attachment
mounted using a tachometer to make certain

exceed rated speed stamped or printed on the
name plate.
Die Grinders in use on the job must be similarly
checked at least once each shift, When checking,
the Adjust Valve of the tool shoud be set for
maximum speed position.
