WARNING

Some dust created by 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, cement, and 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 filter out microscopic particles.

NOTICE

Safety Instructions For Power Tools

5. KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be

kept at a safe distance from work area.

6. MAKE WORKSHOP CHILD PROOF with

padlocks, master switches, or by removing starter keys.

7. DO NOT FORCE TOOL. It will do the job

better and safer at the rate for which it was designed.

8. USE RIGHT TOOL. Do not force tool or

attachment to do a job for which it was not designed.

1. KEEP GUARDS IN PLACE and in working

order.

2. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to

see that keys and adjusting wrenches are removed from tool before turning on.

3. KEEP WORK AREA CLEAN. Cluttered

areas and benches invite accidents.

4. DO NOT USE IN DANGEROUS ENVIRONMENT. Do not use power tools in

damp or wet locations, or where any flammable or noxious fumes may exist. Keep work area well lighted.

9. USE PROPER EXTENSION CORD. Make

sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage rating should be listed on the motor or tool nameplate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Your extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords if they become damaged.

Minimum Gauge for Extension Cords

10. WEAR PROPER APPAREL. Do not wear

loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.

11. ALWAYS USE SAFETY GLASSES. Also

use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.

12. SECURE WORK. Use clamps or a vise to hold

work when practical. It is safer than using your hand and frees both hands to operate tool.

13. DO NOT OVER-REACH. Keep proper

footing and balance at all times.

14. MAINTAIN TOOLS WITH CARE. Keep

tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

15. USE RECOMMENDED ACCESSORIES.

Consult the owner’s manual for recommended accessories. The use of improper accessories may cause risk of injury.

Safety Instructions For Power Tools

16. REDUCE THE RISK OF UNINTENTIONAL STARTING. On machines with magnet-

ic contact starting switches there is a risk of starting if the machine is bumped or jarred. Always disconnect from power source before adjusting or servicing. Make sure switch is in OFF position before reconnecting.

17. MANY WOODWORKING TOOLS CAN “KICKBACK” THE WORKPIECE toward the

operator if not handled properly. Know what conditions can create “kickback” and know how to avoid them. Read the manual accompanying the machine thoroughly.

18. CHECK DAMAGED PARTS. Before fur-

ther use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

19. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Do not

leave tool until it comes to a complete stop.

20. NEVER OPERATE A MACHINE WHEN TIRED, OR UNDER THE INFLUENCE OF DRUGS OR ALCOHOL. Full mental alert-

ness is required at all times when running a machine.

21. NEVER ALLOW UNSUPERVISED OR UNTRAINED PERSONNEL TO OPERATE THE MACHINE. Make sure any

instructions you give in regards to machine operation are approved, correct, safe, and clearly understood.

22. IF AT ANY TIME YOU ARE EXPERIENCING DIFFICULTIES performing the intend-

ed operation, stop using the machine! Then contact our service department or ask a qualified expert how the operation should be performed.

Additional Safety Instructions For Grinders

1. ALWAYS WEAR EYE PROTECTION!

2. MAKE SURE GRINDER IS SECURED FIRMLY TO A BENCH OR STAND BEFORE USE. Any “wobbles” must be

corrected by shimming or blocking before operation.

3. BEFORE MOUNTING A NEW WHEEL, BE SURE WHEEL RPM IS RATED AT AN EQUAL OR HIGHER RPM THAN THE GRINDER.

4. DO NOT GRIND ON THE SIDES OF THE GRINDING WHEELS, unless they

are special wheels designed specifically for this purpose.

5. ONLY USE FLANGES THAT ARE INCLUDED WITH THE GRINDER.

6. WEAR AN APPROVED DUST MASK OR RESPIRATOR. Grinding operations

produce dust.

7. REPLACE A CRACKED WHEEL IMMEDIATELY. DO NOT use a grinding wheel

that has cracks or flaws. Before using, inspect each wheel. Handle wheels carefully to avoid bumping or dropping.

8. DO NOT stand directly in front of grinding

wheels when turning machine on.

9. PERFORM a “ring test” (see page 15) on

grinding wheels to ensure that they are safe for use. Always inspect grinding wheels before operation.

10. HOLD THE WORKPIECE FIRMLY WHILE GRINDING.

11. DO NOT allow your hands to come into

contact with grinding wheels during operation. Abrasive accessories have the ability to remove a lot of material, including skin, very quickly. However, DO NOT wear gloves while grinding, they may get caught in the grinding wheel.

12. KEEP TOOL REST AS CLOSE AS POSSIBLE TO GRINDING WHEEL.

13. NEVER GRIND BY PLACING THE WORKPIECE ON TOP OF THE WHEEL. The wheel may kick the work-

piece toward the operator. Always grind on the downward part of the wheel.

14. DO NOT USE A DUST COLLECTOR OR SHOP•VAC

WHEN SANDING

METAL or damage to your dust collec-

tion equipment or fire may result!

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to follow guidelines could result in serious personal injury, damage to equipment or poor work results.

To operate this or any power tool safely and efficiently, become as familiar with it as possible. The time you invest before you begin to use your Model H3368 will be time well spent. DO NOT operate this machine until you are completely familiar with the contents of this manual, or serious personal injury may occur.

110V Operation

SECTION 3: CIRCUIT REQUIREMENTS

If you find it necessary to use an extension cord with the Model H3368, make sure the cord is rated Hard Service (grade S) or better. Refer to the chart in the standard safety instructions to determine the minimum gauge for the extension cord. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn or damaged.

Extension Cords

Grounding

This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no circumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur.

In the event of an electrical short, grounding reduces the risk of electric shock by providing electric current a path of least resistance. This tool is equipped with a power cord having an

equipment-grounding conductor. See Figure 1B.

The outlet must be properly installed and grounded in accordance with all local codes and ordinances.

The Model H3368 is wired for 110V and will draw approximately 8 amps under load. If you operate this machine on any circuit that is already close to its capacity, it might blow a fuse or trip a circuit breaker. However, if an unusual load does not exist and a power failure still occurs, contact a qualified electrician or our service department.

A 10 amp dedicated circuit should be used with this grinder. Always check to see if your current wires are capable of handling a 10 amp load. If you are unsure, consult the advice of a qualified electrician.
