GENERAL SAFETY RULES

Failure to follow these rules may result in serious personal injury.

1.FOR YOUR OWN SAFETY, READ THE INSTRUCTION MANUAL BEFORE OPERATING THE MACHINE. Learning the machine’s application, limitations, and specific hazards will greatly minimize the possibility of accidents and injury.

2.WEAR EYE AND HEARING PROTECTION. ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. USE CERTIFIED SAFETY EQUIPMENT. Eye protection equipment should comply with ANSI Z87.1 standards. Hearing equipment should comply with ANSI S3.19 standards.

3.WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip protective footwear is recommended. Wear protective hair covering to contain long hair.

4.DO NOT USE THE MACHINE IN A DANGEROUS ENVIRONMENT. The use of power tools in damp or wet locations or in rain can cause shock or electrocution. Keep your work area well-lit to prevent tripping or placing arms, hands, and fingers in danger.

5.MAINTAIN ALL TOOLS AND MACHINES IN peak CONDITION. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories. Poorly maintained tools and machines can further damage the tool or machine and/or cause injury.

6.CHECK FOR DAMAGED PARTS. Before using the machine, check for any damaged parts. Check for alignment of moving parts, binding of moving parts, breakage of parts, and any other conditions that may affect its operation. A guard or any other part that is damagedshould be properly repaired or replaced with Delta or factory authorized replacement parts. Damaged parts can cause further damage to the machine and/or injury.

7.KEEP THE WORK AREA CLEAN. Cluttered areas and benches invite accidents.

8.KEEP CHILDREN AND VISITORS AWAY. Your shop is a potentially dangerous environment. Children and visitors can be injured.

9.REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure that the switch is in the “OFF” position before plugging in the power cord. In the event of a power failure, move the switch to the “OFF” position. An accidental start-up can cause injury. Do not touch the plug’s metal prongs when unplugging or plugging in the cord.

10.USE THE GUARDS. Check to see that all guards are in place, secured, and working correctly to prevent injury.

11.REMOVE ADJUSTING KEYS AND WRENCHES BEFORE STARTING THE MACHINE. Tools, scrap pieces, and other debris can be thrown at high speed, causing injury.

12.USE THE RIGHT MACHINE. Don’t force a machine or an attachment to do a job for which it was not designed. Damage to the machine and/or injury may result.

13.USE RECOMMENDED ACCESSORIES. The use of accessories and attachments not recommended by Delta may cause damage to the machine or injury to the user.

14.USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. See the Extension Cord Chart for the correct size depending on the cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

15.SECURE THE WORKPIECE. Use clamps or a vise to hold the workpiece when practical. Loss of control of a workpiece can cause injury.

16.FEED THE WORKPIECE AGAINST THE DIRECTION OF THE ROTATION OF THE BLADE, CUTTER, OR ABRASIVE SURFACE. Feeding it from the other direction will cause the workpiece to be thrown out at high speed.

17.DON’T FORCE THE WORKPIECE ON THE MACHINE.

Damage to the machine and/or injury may result.

18.DON’T OVERREACH. Loss of balance can make you fall into a working machine, causing injury.

19.NEVER STAND ON THE MACHINE. Injury could occur if the tool tips, or if you accidentally contact the cutting tool.

20.NEVER LEAVE THE MACHINE RUNNING UNATTENDED. TURN THE POWER OFF. Don’t leave the machine until it comes to a complete stop. A child or visitor could be injured.

21.Turn the machine “OFF”, and disconnect the machine from the power source before installing or removing accessories, changing cutters, adjusting or changing set-ups. When making repairs, be sure to lock the start switch in the “OFF” position. An accidental start-up can cause injury.

22.MAKE YOUR WORKSHOP CHILDPROOF WITH PADLOCKS, MASTER SWITCHES, OR BY REMOVING STARTER KEYS. The accidental start-up of a machine by a child or visitor could cause injury.

23. STAY ALERT, WATCH WHAT YOU ARE DOING, AND USE

COMMON SENSE. DO NOT USE THE MACHINE WHEN YOU ARE TIRED OR UNDER THE INFLUENCE OF DRUGS, ALCOHOL, OR MEDICATION. A moment of inattention while operating power tools may result in injury.

24. Use of this tool can generate and disburse dust or other airborne particles, including wood dust, crystalline silica dust and asbestos dust.Direct particles away from face and body. Always operate tool in well ventilated area and provide for proper dust removal. Use dust collection system wherever possible. Exposure to the dust may cause serious and permanent respiratory or other injury, including silicosis (a serious lung disease), cancer, and death. Avoid breathing the dust, and avoid prolonged contact with dust. Allowing dust to get into your mouth or eyes, or lay on your skin may promote absorption of harmful material. Always use properly fitting NIOSH/OSHA approved respiratory protection appropriate for the dust exposure, and wash exposed areas with soap and water.

ADDITIONAL SPECIFIC SAFETY RULES

Failure to follow these rules may result in serious personal injury.

1.Do not operate this machine until it is completely assembled and installed according to the instructions. A machine incorrectly assembled can cause serious injury.

2.OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not thoroughly familiar with the operation of this machine. Knowledge is safety.

3.FOLLOW ALL WIRING CODES and recommended electrical connections to prevent shock or electrocution.

4.ALWAYS USE THE PROVIDED BLOTTER and wheel flanges to mount the grinding wheels on the grinder shaft to prevent wheel damage or acciden-tal separation. Separation can result in fragments flying off the wheel at high speeds.

5.USE ONLY WHEELS suitable for the speed of the machine. Unsuitable grinding wheels can come apart, throwing fragments out at high speeds.

6.USE ONLY WHEELS that have a bore exactly equal to the arbors of the machine. Never attempt to machine an undersized wheel to fit an arbor. Unsuitable grinding wheels can come apart, throwing fragments out at high speeds.

7.DO NOT overtighten wheel nut.

8.DO NOT USE A WHEEL THAT VIBRATES. Dress the grinding wheel, replace it, or replace the bearings of the shaft. Unsuitable grinding wheels can come apart, throwing fragments at high speeds.

9.INSPECT WHEELS before starting the machine for cracks or fragments.REPLACE DAMAGED WHEELS immediately. Parts of the wheel can be thrown at high speeds causing serious injury.

10.ADJUST EYE SHIELDS close to the grinding wheel, andre-adjustas the wheel wears down. Flying sparks are dangerous and can cause fires or explosions.

11.ALWAYS MAKE SURE the eye shields are in place, properly adjusted, and secured.

12.ADJUST TOOL RESTS close to the grinding wheel (1/8" separation or less). Tighten the tool rest securely to prevent shifting positions, andre-adjustas the wheel wears down. The workpiece can be drawn into the wheel, causing damage to the workpiece and/or serious injury.

13.Stand to one side before turning the machine "ON". Loose fragments or wheel parts could fly from the wheel at high speeds.

14.NEVER GRIND ON A COLD WHEEL. Run the grinder for one full minute before applying the workpiece. A cold wheel has a tendency to chip. Those fragments could fly from the wheel at high speeds.

15.Never start the machine with the workpiece against the grinding wheel. The workpiece can be drawn into the wheel, causing damage to the machine and/or serious injury.

16.CLEAN THE MACHINE thoroughly when processing different types of workpieces (wood, steel, or aluminum). Combining wood and metal dust can create an explosion or fire hazard.DO NOT GRIND or polish magnesium. Fire will result.

17.NEVER GRIND NEAR FLAMMABLE GAS OR LIQUIDS.

Sparks can create a fire or an explosion.

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

19.KEEP ARMS, HANDS, and fingers away from the wheel. The abrasive surfaces can cause serious injury.

20.HOLD THE WORKPIECE FIRMLY against the tool rest. Loss of control of the workpiece can cause serious injury.

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

22.GRIND A WORKPIECE using the face of the grinding wheel only. Loss of control of the workpiece can cause serious injury.

23.NEVER APPLY COOLANT directly to the grinding wheel. Coolant can weaken the bonding strength of the grinding wheel and cause it to fail. Dip the workpiece in water to cool it.

24.DO NOT TOUCH the ground portion of a workpiece until it has cooled sufficiently. Grinding creates heat.

25.PROPERLY SUPPORT LONG OR WIDE workpieces. Loss of control of the workpiece can cause serious injury.

26.Never Perform layout, assembly, or set-up work on the table/work area when the machine is running. A sudden slip could cause a hand to move into the wheel. Severe injury can result.

27.Turn the machine "OFF", disconnect the machine from the power source, and clean the table/work area before leaving the machine.Lock the switch in the "OFF" position to prevent unauthorized use. Someone else might accidentally start the machine and cause serious injury to themselves.

POWER CONNECTIONS

A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wireextension cords which have3-pronggrounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the switch (s) is in the "OFF" position and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the machine.

Do not expose the machine to rain or operate the machine in damp locations.

MOTOR SPECIFICATIONS

Your machine is wired for 120 volts, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the "OFF" position.

GROUNDING INSTRUCTIONS

This machine must be grounded while in use to protect the operator from electric shock.

1.All grounded, cord-connected machines:

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This machine is equipped with an electric cord having an equipment-groundingconductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-groundingconduc-tor can result in risk of electric shock. Theconductor with insulation having an outer surface that is green with or without yellow stripes is theequipment-groundingconductor. If repair or replacement of the electric cord or plug is necessary, do not connect theequipment-grounding conductorto a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or  if in doubt as to whether the machine is properly grounded.

Use only 3-wireextension cords that have3-pronggrounding type plugs and matching3-conductorreceptacles that accept the machine’s plug, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.

2.Grounded, cord-connectedmachines intended for use on a supply circuit having a nominal rating less than 150 volts:

If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like the adapter illustrated in Fig. B, may be used to connect this plug to a matching2-conductorreceptacle as shown in Fig. B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. Thegreen-coloredrigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Whenever the  adapter is used, it must be held in place with a metal screw.

NOTE:In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.

In all cases, make certain that the receptacle in question is properly grounded. If you are not sure, have a qualified electrician check the receptacle.

To lock the machine, grasp the switch toggle (A) and pull it out of the switch (Fig. 8). With the switch toggle (A) removed, the switch will not operate. However, should the switch toggle be removed while the grinder is running, the machine can be turned "OFF,"but cannot be restarted without re-inserting the switch toggle (A).

In the event of a power outage (such as a breaker or fuse trip), always move the switch to the "OFF" position until the main power is restored.

FLEXIBLE LAMP

The flexible lamp oper­ates­ inde­pen­dent­ly­ of the grinder. To turn the lamp on and off, rotate the switch (A) Fig. 10.

To reduce the risk of fire, use 40 watt or smaller, 120 volt, reflector track type light bulb (not supplied). A standard­ household­ light bulb should not be used. The reflector track type light bulb should not extend below the lamp shade.
