M1107 Bench grinder

SET

UP

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.

assembly.

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.

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.

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.
