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

5

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.

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

TILTING THE TABLE

Disconnect the machine from the power source!

See Figure 14.

You can tilt the band saw table up to 45° to the right. To tilt the table to the right.

•Loosen the black table tilt locking wing nut (A), located underneath the lower trunnion.

•Tilt the table to the desired angle as shown on the tilt scale (B).

•Retighten the table tilt locking wing nut.

The table can also be tilted 3° to the left for applications such as cutting cast moldings. To tilt the table to the left:

•Follow the instructions above and tilting the table to the right. The table should be tilted enough to allow access to the 0° stop bolt (C) located on the lower trunnion.

•Remove the 0° stop bolt.

•Loosen the table tilt locking wing nut, tilt the table all the way to left.

•Retighten the table tilt locking wing nut.

Figure 14

POSITIONING THE UPPER BLADE GUIDE

IMPORTANT: Proper positioning of the upper blade guide is required to ensure an accurate cut. It also serves to prevent operators fingers from coming in contact with the saw blade.

See Figure 15.

The upper blade guide (A) should be positioned approximately 1/16" above the top of the workpiece, just high enough to allow the workpiece to pass under the blade guide assembly.

To set the upper blade guide to the proper height:

•Loosen the lock knob (B) and move the blade guide assembly to the desired position.

•Retighten the lock knob.

IMPORTANT: Prior to using the band saw, always check guide post lock knob and tighten if necessary.

Figure 15

13

OPERATION

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 (Figure 16)

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.

Figure 16

ADJUSTMENTS

ADJUSTING THE BLADE TENSION

Disconnect the machine from the power source before making any adjustments!

See Figure 17 (show set up as in sample to the rightCaption: A standard blade should have approximately 1/4" deflection on either side.)

Unless you have a tension meter, achieving optimum blade tension is a matter of trial and error. There are a number of suggested methods for achieving the proper tension.

Most blade manufacturers recommend 15,000 psi to 20,000 psi for a common carbon-steel blade. Stronger bimetal, spring-steel, and carbide-tipped blades generally require 25,000 psi to 30,000 psi. The tighter the blade is stretched, the more rigid it becomes and the less tendency it will have to deflect in the cut.

It should be noted that maximum blade tension is only required for the most demanding cuts, such as re-sawing dense hardwoods or stock of maximum thickness.

NOTE: DELTA® Timber Wolf® band saw blades are recommended as they are designed to operate with less tension, thus increasing their serviceable life. Follow the tensioning directions on the package

To check and adjust the blade tension on your DELTA® 14" Steel Frame Band Saw, do the following:

Disconnect the machine from the power source before making any adjustments!

•Set the upper blade guide assembly about 6 in. off the table.

•Use a moderate amount of pressure with your index finger to push the blade sideways in both directions. The blade should not deflect more than 1/4" in either direction.

•If the blade deflects more than 1/4", increase the tension on the blade by tightening the blade

tensioning knob at the top of the machine (refer to B in Figure 6, page 9).

•If the blade does not deflect at all, it may be too tight. Loosen the blade tensioning knob slightly until there is a minimal amount of deflection.

ADJUSTMENTS

ADJUSTING THE BLADE GUIDES AND BEARINGS

See Figure 18.

Disconnect the machine from the power source before making any adjustments!

Adjust the upper blade guides and blade support bearings only after the blade has the correct tension and is tracking properly.

The DELTA® 14" Steel Frame Band Saw features two upper and lower side bearings and two upper and lower rear bearings that can be adjusted in order to ensure straight and consistent cuts. It is recommended that you periodically check the position of all bearings and adjust if necessary.

Side Bearings

The upper and lower side bearings (A) should be positioned so that there is approximately 1/64" gap on either side of the blade. To adjust the position of the bearings, side-to-side, do the following:

•Use a 3MM Allen wrench to loosen the bearing screws (B).

•Reposition the bearings and tighten the bearing the screws.

The upper and lower side bearings also adjust back and forth and should be positioned so that the front edge of the bearings is just behind the blade gullet. To adjust the position of the bearings, front-to-back, do the following:

•Use a 13MM open wrench to loosen the top retaining nut and a 10MM open wrench to loosen the bottom retaining nut. (The bottom retaining nut can be made more accessible by tilting the table slightly.)

•With the retaining nut loosened, both upper side bearings or both lower side bearings will move back and forth as a unitPosition them so that the front edge of the bearings are just behind the blade gullet.

•Re-tighten the retaining nuts.

Rear Bearings

NOTE: The upper and lower side bearings must both be set in place prior to adjusting the upper and lower rear bearings.

The upper and lower rear bearings should be positioned so that they nearly touch the blade.

•To adjust, use a 3MM Allen wrench to loosen the bearing screws.

•Reposition the bearings and tighten the bearing the screws.

MAINTENANCE

STARTING AND STOPPING THE SAW

Make sure that the switch is in the "OFF" postion. To reduce the risk of injury, turn unit off and disconnect it from power source

before installing and removing accessories, before adjusting or when making repairs.

An accidental start-up can cause injury.

FAILURE TO START

Should your machine fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line.

KEEP MACHINE CLEAN

Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth.

NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

Wear certified safety equipment for eye, hearing and respiratory protection while

using compressed air

LUBRICATION & RUST PROTECTION

Apply household floor paste wax to the machine table, extension table or other work surface weekly. Or use a commercially available protective product designed for this purpose. Follow the manufacturer’s instructions for use and safety.

To clean cast iron tables of rust, you will need the following materials: a sheet of medium Scotch-Brite™ Blending Hand Pad, a can of WD-40® and a can of degreaser. Apply the WD-40 and polish the table surface with the Scotch-Brite pad.

Degrease the table, then apply the protective product as described above.
