OPERATION

Caution: The grinding wheels must al- ways be checked for cracks of imper- fections. This is done with the “ring test”. Tap the wheel gently near the outer rim with the handle of a screw- driver; you should hear a clear bell- like ringing. If a dull thud occurs do not use the wheel! This means the wheel has been damaged and will, most likely, come apart during normal operations.

Operation Notes

The 10” Bench Grinder comes as- sembled with a coarse GRINDING WHEEL (2) and a fine GRINDING WHEEL. Determine which wheel is which before attempting to use the Bench Grinder.

The workpiece will quickly become heated. Frequently quench the work- piece in water during the grinding process. If the metal becomes heat- ed so much that it gets blue-colored, it will be too soft to be useful. You must grind off the part that is colored, cool the workpiece, and start again.

General Operation

1.Obtain a tray that is large enough for the workpiece to fit into, fill it with water and place it near the Bench Grinder.

2.Turn the Bench Grinder on.

3.Once the GRINDING WHEEL has reached full speed, bring the work- piece up to the wheel gently and without jarring.

4.Use the TOOL REST (7) to steady the workpiece.

5.The workpiece will become quickly heated. Frequently quench it in wa- ter.
