Loosen the collet nut and insert the wheel point into the 
collet nut. Use one wrench to hold the spindle and the 
other one to tighten the collet nut securely. 
The wheel point should not be mounted more than 8 
mm from the collet nut. Exceeding this distance could 
cause vibration or a broken shaft. 
To remove the wheel point, follow the installation 
procedure in reverse.

which you intend to use. 

OPERATION

Turn the tool on without the wheel point making any 
contact with the workpiece and wait until the wheel point 
attains full speed. Then apply the wheel point to the 
workpiece gently. To obtain a good finish, move the tool 
in the leftward direction slowly. 

 

CAUTION:

Apply light pressure on the tool. Excessive 
pressure on the tool will only cause a poor finish 
and overloading of the motor.
