It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.
WARNING: Some dust created by 19. power sanding, sawing, grinding, drilling, and other construction activities, contains chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and
cement or other masonry products
• Arsenic and chromium from
chemically treated lumber Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially
designed to lter out microscopic
particles. (California Health & Safety Code §
25249.5, et seq.)
WARNING: Handling the cord on 20. this product will expose you to lead, a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. Wash hands after handling. (California Health & Safety Code §
25249.5, et seq.)
Vibration Safety
This tool vibrates during use. Re­peated or long-term exposure to vibration may cause temporary or permanent physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury:
Anyone using vibrating tools regu-1. larly or for an extended period should
rst be examined by a doctor and
then have regular medical check­ups to ensure medical problems are not being caused or worsened from use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, ner­vous system disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any medical or physical symptoms related to vibra­tion (such as tingling, numbness, and
white or blue ngers), seek medical
advice as soon as possible.
Do not smoke during use. Nico-2. tine reduces the blood supply to the
hands and ngers, increasing the risk
of vibration-related injury.
Wear suitable gloves to reduce the 3. vibration effects on the user.
Page 7For technical questions, please call 1-800-444-3353.SKU 6510
Page 8
Use tools with the lowest vibration 4. when there is a choice between dif­ferent processes.
Include vibration-free periods each 5. day of work.
Grip tool as lightly as possible (while 6. still keeping safe control of it). Let the tool do the work.
To reduce vibration, maintain the tool 7. as explained in this manual. If any abnormal vibration occurs, stop use immediately.

Dressing the Wheel
New wheels frequently are not true and during operation often become grooved, glazed, out of round, or misshapen. At these times, they will need dressing. You will need a grind­ing wheel dresser for this operation. Dressers are available from Harbor Freight Tools.
Standing to the side of the wheel, let 1. the Bench Grinder run for a full min­ute with no load. If the GRINDING WHEEL runs straight and true, you will not need to dress it prior to op­erating. If it is not, proceed with the following steps.

OPERATION
General Operation
Caution: The grinding wheels must al-
ways be checked for cracks of imper­fections. This is done with the “ring test”. Tap the wheel gently near the outer rim with the handle of a screw­driver; you should hear a clear bell­like ringing. If a dull thud occurs do not use the wheel! This means the wheel has been damaged and will, most likely, come apart during normal operations.
Operation Notes
The 10” Bench Grinder comes as­sembled with a coarse GRINDING
WHEEL (2) and a ne GRINDING
WHEEL. Determine which wheel is which before attempting to use the Bench Grinder.
Obtain a tray that is large enough 1.
for the workpiece to t into, ll it with
water and place it near the Bench Grinder.
Turn the Bench Grinder on.2.
Once the GRINDING WHEEL has 3. reached full speed, bring the work­piece up to the wheel gently and without jarring.
Use the TOOL REST (7) to steady 4. the workpiece.
The workpiece will become quickly 5. heated. Frequently quench it in wa­ter.
The workpiece will quickly become heated. Frequently quench the work­piece in water during the grinding process. If the metal becomes heat­ed so much that it gets blue-colored, it will be too soft to be useful. You must grind off the part that is colored, cool the workpiece, and start again.
