18. DO NOT TURN THE MOTOR SWITCH ON AND OFF RAPIDLY. This could cause the wheel to
loosen and create a hazard. Should this ever occur, stand clear and allow the wheel to come to a
complete stop. Disconnect your grinder from the power supply and retighten the wheel nut securely.
19. RISK OF INJURY DUE TO ACCIDENTAL STARTING. Do not use in an area where children
may be present.
20. NEVER START THE GRINDER when the wheel is in contact with the workpiece.
21. SECURE WORK. Always hold the workpiece firmly against the work rest.
22. DO NOT USE THE BENCH GRINDER if the flange nut or clamp nut is missing or if the spindle
shaft is bent.
23. FREQUENTLY clean grinding dust from beneath the grinder.
24. DO NOT OPERATE THIS TOOL WHILE UNDER THE INFLUENCE OF DRUGS,
ALCOHOL OR ANY MEDICATION.
25. ALWAYS STAY ALERT. Do not allow familiarity (gained from frequent use of your grinder) to
cause a careless mistake. ALWAYS REMEMBER that a careless fraction of a second is sufficient to
inflict severe injury.
26. STAY ALERT AND EXERCISE CONTROL. Watch what you are doing and use common sense. Do
not operate the tool when you are tired. Do not rush.
27. SAVE THESE INSTRUCTIONS. Refer to them frequently and use them to instruct other users. If
you loan someone this tool, loan them these instructions also.
28. 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.
29. USE ONLY FLANGES furnished with this bench grinder.
30. IF ANY PART OF THIS GRINDER IS MISSING or should break, bend, fail in any way, or should
any electrical component fail to perform properly, shut off the power switch, remove the machine plug
from the power source and have damaged, missing, or failed parts replaced before resuming operation.
31. SAFETY SHIELD AND SPARK DEFLECTOR. The safety shields and spark deflectors are
adjustable for operator convenience. Operating the grinder without these features attached could result
in serious injury. Do not grind with the safety shield raised. Always wear safety glasses for personal
protection.

32. WORK REST. The work rests are independently adjustable to compensate for wheel wear. Before
grinding, make certain the work rests are adjusted properly. Generally, the object being ground is done
slightly above the center of the grinding wheel.
33. Lawn mower blades are usually sharpened on only one edge and dressed up slightly on the other.
Perform this sharpening process on both cutting ends of the blade. After sharpening, balance the blade
by removing additional material.
