WARNING: Do not plug in or operate this tool until the entire manual has been read and understood.
Failure to do so may result in personal injury or machine damage.
1. Use only the correct grinding wheels that meet the following requirements:
• The speed rating of the wheel is greater than 3450 RPM.
• The wheel complies with ANSI B7.1.
• The size of the wheel is 6 inches in diameter and 3/4 inch thick with a 1/2-inch arbor. Do not use wheels
with incorrect arbor size.
2. Always inspect grinding wheels prior to use for cracks or missing pieces. If imperfections are present, replace
wheel immediately before use. Never use wheel washers or screws that are defective or incorrect.
3. Thoroughly inspect the grinder. Do not use the bench grinder if the flange nut or arbor hex nut is missing or if
the spindle shaft is bent. Use only flanges furnished with this bench grinder.
4. Never touch a grinding wheel or other moving parts during operation or immediately after use. It takes approxi-
mately 3 minutes for the wheels to come to a stop after the tool is switched off.
5. Do not overtighten the wheel nut. Do not use an impact wrench to make adjustments to the grinding wheel nuts,
as it could cause damage to the wheel, which could cause severe injury.
6. Risk of injury due to accidental starting. Do not use in an area where children may be present.
7. Always secure the bench grinder by bolting it down to its supporting surface to prevent the grinder from tipping
over, sliding, or walking during operation.
8. Do not remove the wheel guard, unless changing a grinding wheel. Ensure the cover is replaced before using the
grinder. Always use the guards, spark deflectors and eye shields during operation.
9. Check the ON/OFF switch of your tool. Do not use tool if switch does not turn it on and off. Have defective
switches replaced by an authorized service center.
10. Stand beside the bench grinder during start-up, not directly in front. Never stand or have any part of your body
in line with the path of the wheel.
11. Never start the grinder when the wheel is in contact with the workpiece.
12. Always hold the workpiece firmly against the work rest.
13. Always ease the workpiece against the abrasive wheel when starting to grind. A harsh impact can break the wheel.
Use light pressure when starting to grind. Too much pressure on a cold wheel can cause the wheel to crack.
14. Do not use the grinding wheel to cut anything.
15. Do not apply excess stress to the grinding wheel. Excessive pressure may damage the tool, cause the motor to
overheat, and prematurely wear down the grinding wheel.
