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 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 THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE, HAVE A qualified ELECTRICIAN CHECK THE RECEPTACLE.

The ability to fine-tune the speed also aids in managing intricate cuts, such as those needed for detailed scroll work.

The scroll saw is equipped with a large, 16-inch throat depth, which provides ample room for cutting larger workpieces without compromising precision. This generous size, combined with a rigid steel frame, ensures stability and reduces vibration during operation, resulting in smoother cuts and greater control.

Another highlight of the Delta 50-871 is its tool-less blade change system. This innovation allows users to easily and quickly switch blades without the need for additional tools, enhancing workflow and minimizing downtime. The saw is compatible with a wide variety of blade types, making it easy to tailor to specific projects.

The integrated dust blower is another intelligent feature, keeping the cutting line clear of sawdust, which enhances visibility and accuracy. Coupled with a sturdy work table that can be tilted up to 45 degrees, users can achieve a variety of cutting angles, providing even more versatility in their woodworking tasks.

Safety is a paramount consideration in the design of the Delta 50-871. It features an easy-to-access on/off switch, providing quick power control, while its blade guard ensures that users are protected during operation. Additionally, the saw is designed with a flat surface area that helps prevent tipping and increases stability during use.

In summary, the Delta 50-871 scroll saw offers a comprehensive blend of features and technologies ideal for anyone looking to achieve precision in woodworking. With its variable speed, large throat depth, easy blade changes, and safety features, it stands out as a reliable tool that meets the demands of various cutting applications. Whether you are creating intricate patterns or handling larger projects, the Delta 50-871 is equipped to deliver superior performance and craftsmanship.
