When you face the bench grinder, the wheel on your left is a 120 grit grinding wheel. The wheel to your right (J) is a 60
grit grinding wheel. These wheels are used for grinding wood and plastic, removing paint and rust, polishing metal, hon-
ing cutting tools, smoothing rough edges on glass, sheet metal, etc.
To operate the bench grinder, put of safety glasses or other eye protection and hold the work firmly. Rest the work on the
tool rest and feed it slowly into the wheel at the desired grinding angle. Treat the wheel with respect, never jam work into
the wheel or use unnecessary pressure.
Grind only on the face of the grinding wheel, unless you have special wheels specifically made to permit grinding on the
side of the wheel. This bench grinder is equipped with two grinding wheels.
Before Starting
1. The Power Switch must be in the “OFF” position and the Variable Speed Switch must be turned to its slowest setting
by being turned all the way to the left until solid resistance is felt.
2. Stand to the side of the Bench Grinder and plug in the power cord to a suitable power source.
3. Remain to the side of the Bench Grinder and turn it “ON” by moving the power switch to the up position.
4. Allow the grinding wheels to come up to a steady speed for at least one minute. The R.P.M.’s of the Bench Grinder
can be now increased to the desired speed for the particular grinding operation by rotating the Variable Speed Switch
clockwise.
5. Adjust the eyeshields. Place the workpiece on the appropriate tool rest for the desired operation.
6. Move the workpiece towards the grinding wheel until it lightly touches. Move
the workpiece back and forth across the front surface of the grinding wheel removing the amount of material desired.
To avoid serious injury, never grind on the sides of the grinding wheels.
7. To use the Drill Bit Sharpening tool rest, lay the drill bit flat in the “V” groove. Firmly hold on to the drill bit shank. Slide
the drill bit towards the grinding wheel unit until it lightly touches. Keep the drill bit flat to the plate and rotate the drill bit.
8. The operator may place the hot end of the workpiece into the water in the quench tray to cool it.
9. After completing the grinding operations, turn “OFF” the Bench Grinder by pushing down on the Power Switch.
It will take a few minutes for the grinding wheels to come to a complete stop.
10. Turn the Variable Speed Switch counterclockwise to return it to its slowest setting.
If used, the Flexible Work Light housing will remain hot for a few minutes after turning it “OFF”. Avoid contact with hous-
ing until it is cool.
11. Unplug the Bench Grinder from the power source. NOTE: To prevent unauthorized use of the Bench Grinder, the
power switch has a removable locking key. With the power switch in the “OFF” position, pull the locking key out. The
Bench Grinder cannot be turned “ON” with the key removed. Insert the locking key to resume grinding operations.
