M1107 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 workpiece against the wheel.
The eye shield must be installed and positioned between the grinding 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 protection.
Using the hardware from the Inventory list on Page
7, assemble the tool rests and eye shields as they are shown in Figures 6 & 7.
Grinding Wheel
Installation
Before installing the included grinding wheels, you must 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 that is suspected of having cracks, or if there are visual chips, nicks or dents in the wheel surface. This damage can lead to wheel failure, causing the wheel to fly apart at operating speed.
Always be sure to use a Type 1 wheel that is rated for operating at 1725 RPM or greater. Install the grinding wheel, paper disc, wheel flange, and nut in the order shown in Figure 7, and then attach the side cover.

NEVER assemble a grinding wheel on the arbor without paper or fiber discs between the wheel and the mount- ing flange. Omitting the discs can put undue stress on the wheel, causing it to crack and possibly fly apart.
