M1051 6" Bench Grinder
Tool Rest and Eye Shield
The tool rest supports the workpiece during grinding. Certain types of grinding may require jigs or accessories to assure the proper angle of the work piece against the wheel.
The eye shield must be positioned between the grind- ing wheel and your face during grinding. The eye shield is NOT a substitute for safety glasses or a safety face shield. You must wear ANSI approved face and eye pro- tection.
Using the hardware from the Inventory list on Page 7; assemble the tool rest and eye shield as they are shown in Figure 5.
Grinding Wheel
Installation
Before installing the included grinding wheels, check them for integrity by performing a “ring test.” Hang on a string, then lightly tap the rim of the wheel with a piece of wood such as the handle of a hammer. The wheel should have a ringing or harmonic type of sound. If the wheel responds with a dull thud it may indicate that the wheel has cracks. Do not use a wheel which is suspected of having cracks, or if there are visual chips, nicks or dents in the wheel surface. These discontinuities can lead to wheel failure causing the wheel to fly apart at operating speed.
Always be sure to use a wheel that is rated for operating at speeds equal to or greater than 3450 RPM. Install the grinding wheel, paper disk, wheel flange, and nut in the order shown in Figure 6, and then attach the side cover.
Note: The arbor shaft and nut on the left hand side of the grinder is a left hand thread, so tightening it will require turning it counterclockwise.

assembly.
NEVER assemble a grinding wheel on the arbor without paper or fiber discs between the wheel and the flange. Omitting the discs can put undue stress on the wheel causing it to crack and possibly fly apart. ALWAYS “ring test” a wheel before assembly to make certain it is sound with no cracks or flaws.
