OPERATING INSTRUCTIONS
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.
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.
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.
