MANUAL INSTRUCTION

SAFETY RULES

Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop. If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your personal safety is your responsibility.

This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not be modified and/or used for any application other than that for which it was designed. If you have any questions relative to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should be performed on the product.

WARNING: FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY

1.FOR YOUR OWN SAFETY, READ INSTRUCTION MANUAL BEFORE OPERATING THE TOOL. Learn the tool’s application and limitations as well as the specific hazards peculiar to it.

2.KEEP GUARDS IN PLACE and in working order.

3.ALWAYS WEAR EYE PROTECTION.

4.REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it “on”.

5.KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

6.DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or expose them to rain. Keep work area well-lighted.

7.KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be kept a safe distance from work area.

8.MAKE WORKSHOP CHILDPROOF – with padlocks, master switches, or by removing starter keys.

9.DON’T FORCE TOOL. It will do the job better and be safer at the rate for which it was designed.

10.USE RIGHT TOOL. Don’t force tool or attachment to do a job for which it was not designed.

11.WEAR PROPER APPAREL. No loose clothing, gloves, neckties, rings, bracelets, or other jewelry to get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.

12.ALWAYS USE SAFETY GLASSES. Wear safety glasses. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses. Also use face or dust mask if cutting operation is dusty. These safety glasses must conform to ANSI Z87.1 requirements. Note: Approved glasses have Z87 printed or stamped on them.

13.SECURE WORK. Use clamps or a vise to hold work when practical. It’s safer than using your hand and frees both hands to operate tool.

14.DON’T OVERREACH. Keep proper footing and balance at all times.

15.MAINTAIN TOOLS IN TOP CONDITION. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

16.DISCONNECT TOOLS before servicing and when changing accessories such as blades, bits, cutters, etc.

17.USE RECOMMENDED ACCESSORIES. The use of accessories and attachments not recommended by Delta may cause hazards or risk of injury to persons.

18.R E D U C E T H E R I S K O F U N I N T E N T I O N A L STARTING. Make sure switch is in “OFF” position before plugging in power cord.

19.NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is accidentally contacted.

20.CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to ensure 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.

21.DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the blade or cutter only.

22.NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop.

23.DRUGS, ALCOHOL, MEDICATION. Do not operate tool while under the influence of drugs, alcohol or any medication.

24.MAKE SURE TOOL IS DISCONNECTED FROM POWER SUPPLY while motor is being mounted, connected or re-connected.

25.THE DUST GENERATED by certain woods and wood products can be injurious to your health. Always operate machinery in well ventilated areas and provide for proper dust removal. Use wood dust collection systems whenever possible.

26. WARNING: SOME DUST CREATED BY POWER SANDING, SAWING, GRINDING, DRILLING, AND OTHER CONSTRUCTION ACTIVITIES contains chemicals known 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 and other masonry products, and

• 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.

ADDITIONAL SAFETY RULES FOR

GRINDERS

1.DO NOT operate your tool until it is completely assembled and installed according to the instructions.

2.IF YOU ARE NOT thoroughly familiar with the operation of grinders, obtain advice from your supervisor, instructor or other qualified person.

3. USE only grinding wheels rated for 3600 RPM with a 5/8" or 1" arbor hole, for Models 23-730 & 23-725. NEVER use a wheel rated lower than 3600 RPM for Model 23-730, NEVER use a wheel rated lower than 1800 RPM for Model 23-725, or attempt to machine an undersize wheel to fit an arbor. Model 23-735 uses grinding wheels rated for 1800 RPM with a 3/4" or 1-1/4" arbor hole. NEVER use a wheel rated lower than 1800 RPM for Model 23-735.

4.NEVER use a chipped or cracked grinding wheel. ALWAYS inspect each wheel before mounting on the grinder. REPLACE A CRACKED WHEEL IMMEDI-

ATELY.

5.DO NOT overtighten wheel nut.

6.FREQUENTLY clean grinding dust from beneath the grinder.

7.ALWAYS maintain a distance of 1/8" or less between the grinding wheel and the tool rest. Adjust the tool rests as the grinding wheels decrease in size with use.

8.SECURELY tighten tool rests so they cannot shift position while in use.

9.NEVER grind on a cold wheel. The grinder should always be started and run at idle speed for one full minute before applying work.

10.NEVER grind on the side of the wheel. ALWAYS grind on the face of the wheel only.

11.NEVER apply coolant directly to a grinding wheel. Coolant can weaken the bonding strength of the wheel and cause it to fail. Dip the workpiece into water to cool it.

12.SPARKS ARE A HAZARD! NEVER grind near flammable gas or liquids.

13.ALWAYS MAKE SURE the wheel guards and eye shields are in place, properly adjusted and secured.

14.KEEP the spark guards close to the wheel and readjust them as the wheel wears.

15.MAKE CERTAIN the blotter and wheel flanges furnished are used to mount the grinding wheels onto the grinder shaft.

16.THE USE of attachments and accessories not recommended by Delta may result in the risk of injuries.

17.STAND to one side of the wheel when turning on the power.

18.AVOID awkward hand positions where a sudden slip could cause a hand to move into the grinding wheel.

19.ALWAYS keep hands and fingers away from the grinding wheel.

20.NEVER start the grinder with the workpiece pressed against the grinding wheel.

21.DRESS the wheel on the face only. Dressing the side of the wheel can cause it to become too thin for safe use.

22.DO NOT use a wheel that vibrates. Dress the wheel, replace the wheel, or replace the shaft bearings, if worn.

23.GRINDING CREATES HEAT. Do not touch the workpiece until you are sure it has cooled sufficiently.

24.YOUR TOOL may start after a power failure. DO NOT use in an area where children may be present.

25.ALWAYS keep guards in place when using a wire brush or buffing wheel in place of the standard grinding wheel.

26.SHOULD any part of your grinder be missing, damaged, or fail in any way, or any electrical component fail to perform properly, shut off switch and remove plug from power supply outlet. Replace missing, damaged or failed parts before resuming operation.

27.ADDITIONAL information regarding the safe and proper operation of this product is available from the National Safety Council, 1121 Spring Lake Drive, Itasca, IL 60143-3201 in the Accident Prevention Manual for Industrial Operations and also in the Safety Data Sheets provided by the NSC. Please also refer to the American National Standards Institute ANSI B7.1 Safety Requirements for the use, care, and protection of abrasive wheels; ANSI B11.9 Safety Requirements for the construction, care and use of grinding machines; and the U.S. Department of Labor OSHA 1910.215 Regulations for Abrasive Wheel Machinery.
