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 (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 120/240 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-grounding conductor 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-grounding conductor can result in risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to 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-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the machine’s plug, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.

2.Grounded, cord-connected machines 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 matching 2-conductor receptacle 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. The green-colored rigid 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.

3. 240 VOLT SINGLE PHASE OPERATION

The motor supplied with your machine is a dual voltage, 120/240 volt motor. It is shipped ready- to-run for 120 volt operation. However, it can be converted for 240 volt operation.

A qualified electrician should do the conversion, or the machine can be taken to an Authorized Delta Service Center. When completed, the machine must conform to the National Electric Code and all local codes and ordinances.

The machine is converted by re-wiring the motor for 240 volts, installing a 240 volt plug on the power supply cord and replacing the switch with one that is rated for 240 volt operation.

Be sure the 240 volt plug is only used in an outlet having the same configuration as the plug illustrated in Fig. C. No adapter should be used with the 240 volt plug.

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.

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-1 or D-2, 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.

MACHINE USE

Before applying power to the machine, make all necessary adjustments and ensure that all guards are in place and are secure. Turn the upper wheel by hand to visually inspect the machine.

Keep the top guide within 1/8" of the workpiece. Do not force the workpiece against the blade. Light pressure will produce a smoother cut and prevent excess friction and heating of the blade. Keep the workpiece moving at a slow and consistent rate.

To prevent twisting of the blade, avoid making sharp corner cuts.

KEEP THE SAW BLADE SHARP.

20 - English

CUTTING CURVES

Turn the stock carefully so that the blade follows without twisting. For very abrupt curves, consider using a narrower blade, or a blade with more set. Another solution to this problem is to make relief cuts (Fig. 39).

When you withdraw the workpiece or change the cut, be careful not to accidentally pull the blade off of the wheels. The preference is to turn the stock and saw out through the waste material.
