SAFETY GUIDELINES / DEFINITIONS
This manual contains information that is important for you to know and understand. This information relates to protecting YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the symbols to the right. Please read the manual and pay attention to these sections.
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury
Used without the safety alert symbol indicates potentially hazardous situation which, if not avoided, may result in property damage.
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.
GENERAL 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.

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-wire extension cords which have 3- prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the switch 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 either 120/240 volt single phase, or 200-230/460 volt three phase, 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.
SINGLE PHASE
INSTALLATION
If the motor on your machine is wired for 115 Volt, Single Phase, the power cord is equipped with a plug that has two flat, parallel current-carrying prongs, and one longer round or “U” shaped, ground prong which requires a mating 3-conductor grounded type receptacle, as shown in Fig. A.
If the motor on your machine is wired for 230 Volt, Single Phase, the power cord is equipped with a plug that has two flat, current-carrying prongs in tandem, and one round or “U”-shaped longer ground prong. This is used only with the proper mating 3-conductor grounding type receptacle,as shown in Fig. B.
When either the 115 Volt or 230 Volt three prong plug on your machine is plugged into a grounded 3-conductor receptacle, the long ground prong on the plug contacts first so the machine is properly grounded before electricity reaches it.
IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE, HAVE A CERTIFIED ELECTRICIAN CHECK THE RECEPTACLE.
THREE PHASE
INSTALLATION
If the motor on your machine is wired for 200, 230 or 460 Volts, Three Phase, refer to the electrical instruction manual supplied with your machine for instructions on how to connect electrical power.
CHANGING VOLTAGE
The single phase 1-1/2 H.P. (push button switch only), 8" Jointer is supplied wired for 230 Volts. If you desire to change the voltage on this unit it is necessary to disconnect the machine from the power source, reconnect the leads in the motor junction box, as shown on the motor nameplate and change the plug to a 115 Volt plug.
If you desire to change the voltage on either the single or three phase, 1-1/2 H.P., 8" Jointer that is equipped with 24 Volt push button station, magnetic starter, transformer and 3-leg overload protection, refer to the the “CHANGING VOLTAGE OF THE LVC MOTOR STARTER” section in the electrical manual supplied with your jointer. The following steps must be completed:

1.Disconnect the machine from the power source.
2.Move the transformer primary pigtail to the proper terminal corresponding to the new input voltage.
3.Change the leads in the motor junction box for the proper line voltage, as shown on the motor nameplate.
4.Change the heater elements in the overload block for the proper voltage/amperage, as shown on the motor nameplate. The correct heater elements can be identified by referring to the chart inside the motor starter box.
CUTTERHEAD ROTATION
The rotation of the cutterhead must be in a clockwise direction when viewed from the left side of the machine; that is, the knives must be rotating toward the infeed table from the top. If the cutterhead rotation is incorrect, disconnect the machine from the power source and proceed as follows:
Single Phase Machines – Interchange leads T5 and T8 in the motor junction box.
Three Phase Machines – Interchange any two of the three incoming power lines.
EXTENSION CORDS
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
