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 tools. 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 tool’s plug. Before connecting the motor 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 tool.

All line connections should make good contact. Running on low voltage will damage the motor.

WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE THE TOOL IN DAMP LOCATIONS.

MOTOR SPECIFICATIONS

Your tool is wired for 120 volt, 60 HZ alternating current. Before connecting the tool to the power source, make sure the switch is in the “OFF” position.

GROUNDING INSTRUCTIONS

WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM

ELECTRIC SHOCK.

1. All grounded, cord-connected tools:

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 tool 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 tool is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the tool’s plug, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.

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

If the tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the tool 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.

WARNING: IN ALL CASES, MAKE CERTAIN THE

Fig. 26

6. The upper blade support bearing (E) Fig. 26 prevents damage to the set in the saw teeth by keeping the blade from being pushed too far toward the back. The support bearing (E) should be set 1/64" behind the blade by loosening the thumb screw

(F) and turning the knurled knob (G) to move the support bearing (E) in or out.

7. Adjust the blade support bearing (E) so that the back edge of the blade overlaps the outside diameter of the ball bearing by about 1/16". The bearing (E) is set on an eccentric. To change the position, remove the screw (H) and bearing (E) Fig. 26. Loosen the thumb screw (F), back out the knurled knob from the set screw. Remove the hex shaft from the hole, and rotate it to move the eccentric for the bearing.

8. When the blade guide wears to a point that it cannot be adjusted close to the blade, loosen screw (B) Fig. 26 and reverse the blade guides (A) Fig. 26.

ADJUSTING LOWER BLADE GUIDES

AND BLADE SUPPORT BEARING

Adjust the lower blade guides and blade support bearing after the the upper guides and bearing have been adjusted.

1. DISCONNECT TOOL FROM POWER SOURCE.

2. Adjust the front edge of the guide blocks (B) so that they are just behind the “gullets” of the saw teeth. Turn the knurled knob (C) Fig. 27 to make this adjustment. Check the support bearing. It should not be touching the back of the blade.

3. Loosen the two screws (A) Fig. 27. Move the guides (B) as close as possible to the side of the blade, being careful not to pinch the blade.

Tighten screws (A).

OPERATING THE BAND SAW

CAUTION: DISCONNECT TOOL FROM POWER SOURCE.

Before engaging the tool, make all adjustments and put all guards in place. Turn the upper wheel clockwise by hand to be sure that everything is correct prior to connecting tool to power source.

Keep the top guide close to the work. Do not force the material against the blade. Light contact with the blade will permit easier following of the line and will prevent excess friction, heating, and work-hardening of the blade at its back edge. Keep the saw blade sharp and very little pressure will be required for average cutting. Avoid twisting the blade by turning abrupt corners.

BAND SAW BLADES

A bandsaw blade is a delicate piece of steel that is subjected to a great deal of strain. Proper blade care results in optimal performance. Always use blades of the proper thickness, width, and temper to correspond to the workpiece. Use the widest blade possible. Narrow blades should be reserved for small, abrupt curves and delicate work.

When pressure is required to push a workpiece through the blade, either file and set the blade, or replace it. A broken blade can be welded or brazed, but if the blade has been work-hardened, it will soon break again. A good rule of thumb is to sharpen the blade after 4 hours of operation.

Band saw blades will break because of the peculiar stresses to which they are subjected. However, many blades break because the operator (1) does not check the alignment and adjust the guides; (2) forces or twists the blade around a short-radius curve;

(3) feeds the workpiece too fast; (4) allows the blade to become dull; (5) tightens the blade tension excessively; (6) sets the top blade guide too high; (7) uses a blade that has been improperly brazed or welded; and/or (8) runs the blade continuously when not cutting. Blades for the standard 14" Band Saw are 93-1/2" long. The saw can adjust to a maximum length of 94" and a minimum of 91-1/2".

10

CHANGING THE BLADES

1. DISCONNECT TOOL FROM POWER SOURCE.

2. Open the upper and lower wheel guards.

3. Release tension on the saw blade.

4. Loosen the table alignment pin (A) Fig. 28 with a wrench and pull it out. Remove table insert.

5. Take the blade off the wheel, and guide it through the slot in the table.

6. Install the new blade by reversing the procedure. (Table alignment pin should be seated by gently tapping it with a hammer).

A

Fig. 28

CUTTING CURVES

When cutting curves, turn the stock carefully so that the blade will follow without being twisted. If a curve is so abrupt that repeated new kerfs are needed, use either a narrower blade or one that has more set. The more set a blade has, the easier the stock is to turn. However, the cut is usually rougher than when using a medium set.

When withdrawing the blade, be careful not to draw the blade off of the wheels. In most cases, it is easier and safer to turn the workpiece and saw out through waste material. Do not back the blade out while the saw is running.
