2. How to grind
Make sure the water is flowing. Move the chamfer machine along the stone workpiece to grind it.
Adjust the water flow, traveling speed and pressure while grinding.
Switch operation
When the switch lever (see “Part names”) is tilted toward the ON label, the machine is
turned on. When it is tilted toward the OFF label, the machine is turned off.
How to handle wheels
After switching the machine ON, and the motor has reached its constant rpm’s, begin
grinding.
When the wheel first comes into contact with the workpiece, make contact slowly.
Do not apply more force onto the machine than is required. Such action may actually
damage the wheel, reduce its working efficiency and shorten the machine’s service life.
To change smoothly from rough chamfering to polishing, the following sequence of
wheel changes is recommended.
Precautions immediately after use
After the job is completed, turn off the switch. After the wheel stops rotating completely, put
the machine in a safe place.
If your hand is released off the machine before the wheel stops rotating, it may cause
an accident. Wait until the machine stops running.
