Harbor Freight Tools 90003 Operating Instructions, INSPECTION, MAINTENANCE, and Cleaning

OPERATING INSTRUCTIONS

1.WARNING! Prior to using the Bench Grinder, make sure to wear ANSI approved safety glasses, full face safety impact shield, and heavy duty work gloves. Also, always adjust the two Eye Shields (part #26) directly in line between your eyes and the object being ground. (See Figure H.) Always keep wheel covers in place when using the Bench Grinder.

2.Plug the Power Cord Plug (part #10) into the nearest grounded, 120 volt, electri- cal outlet. Then, turn the Power Switch (part #3) to its “ON” position and allow the Grinding Wheels (part #64) to spin up to full speed. (See Figure H.)

3.Hold the workpiece being ground with both hands, taking care to keep fingers and hands away from the spinning Grinding Wheels (part #64). (See Figure H.)

4.Place the workpiece on the Left or Right Tool Rest (parts #28, #32), applying moderate pressure on the workpiece and keeping it moving to the left and right at an even pace for smooth grinding. NOTE: Feeding the workpiece too hard into the Grinding Wheel (part #64) can overheat the Motor and prematurely wear down the Grinding Wheel. (See Figure H.)

5.IMPORTANT: Keep a tray nearby filled with water, and dip the workpiece into the water regularly to prevent overheating. Overheating can weaken metals.

6.Once the grinding job is completed, turn the Power Switch (part #3) to its “OFF” position and allow the Grinding Wheels (part #64) to stop on their own. Unplug the Bench Grinder when it is not in use. (See Figure H.)

7.Place the workpiece in the tray of water and allow the workpiece to completely cool before handling.

INSPECTION, MAINTENANCE, AND CLEANING

1.WARNING! Make sure the Power Switch (part #3) of the Bench Grinder is in its “OFF” position and that the tool is unplugged from its electrical outlet be- fore performing any inspection, maintenance, or cleaning procedures.

2.BEFORE EACH USE, inspect the general condition of the Bench Grinder. Check for loose screws, misalignment or binding of moving parts, damaged electrical wiring, cracked, chipped, or damaged Grinding Wheels (part #64), and any other condition that may affect its safe operation. If abnormal noise or vibra- tion occurs, have the problem corrected before further use.

Do not use damaged equipment.
