MANUAL INSTRUCTION

Delta may cause damage to the machine or injury to the user.

14.USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. See the Extension Cord Chart for the correct size depending on the cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

15.SECURE THE WORKPIECE. Use clamps or a vise to hold the workpiece when practical. Loss of control of a workpiece can cause injury.

16.FEED THE WORKPIECE AGAINST THE DIRECTION OF

THE ROTATION OF THE BLADE, CUTTER, OR ABRASIVE SURFACE. Feeding it from the other direction will cause the workpiece to be thrown out at high speed.

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

DISCONNECT MACHINE FROM

POWER SOURCE.

The left and right blade guide brackets (A) and (B) Fig. 22, are adjustable by loosening the two lock knobs (C) and sliding the brackets to accommodate the width of the work piece. The guide brackets (A) and (B) should be set as close as possible to the workpiece, without interfering or touching the workpiece, or contacting the table. Once the adjustment is made, tighten the lock knobs (C).

ADJUSTING FEED RATE

DISCONNECT MACHINE FROM

POWER SOURCE.

The feed rate of the saw arm can be adjusted by turning the control arm (A) Fig. 23, counterclockwise to increase or clockwise to decrease the feed rate. Do not turn the control arm more than one turn at a time. Excessive feed pressure can break or stall the blade. Insufficient feed pressure dulls the blade rapidly.

OPERATING AND

ADJUSTING THE VISE

The workpiece (A) is placed between the vise jaws with the required amount to be cut-off extending out past the blade, as shown in Fig. 24. To tighten the workpiece in the vise, turn handwheel (B).

The vise can be adjusted to cut any angle from 0 degrees to 45 degrees by loosening the two screws (C) Fig. 25, and positioning the vise jaw (D) to the desired angle. A scale (E) is positioned on the rear of the table to give the proper cutting angle. lt may also be necessary when angle cutting to move the left vise jaw (F) to the rear to clear the blade guide bracket.

ADJUSTING STOCK STOP

The stock stop is used when more than one piece is to be cut to the same length. Position the stop block (A) Fig. 26, the desired distance away from the blade. lt is good practice to have the work contact the stop at the bottom of the work, as shown. The stop may be repositioned in or out by loosening set screw (B) and moving the stop accordingly. When not using the stock stop, rotate the stop below the table surface.

For cuts when the work will not extend beyond the table, the stop (C) Fig. 27, can be turned around, as shown, to contact the workpiece.

ARM POSITIONING LEVER

An arm positioning lever (A) Fig. 28, is supplied on the front of the base and can be engaged with one of the two notches (B) depending on the size of the workpiece, for positioning the arm during set-up. The lever (A) should be engaged with notch (C) when operating the saw in the vertical position.

CHANGING SPEEDS AND

ADJUSTING BELT TENSION

DISCONNECT MACHINE FROM

POWER SOURCE BEFORE CHANGING

SPEEDS AND ADJUSTING BELT TENSION.

Proper belt tension is obtained when there is approximately 1/4" deflection of the belt using light finger pressure at the center span of the pulleys. To adjust belt tension, loosen lock nut (C) Fig. 29, and turn adjusting screw (D) clockwise to increase tension and counterclockwise to decrease tension. Tighten locknut

When changing speeds, release belt tension and open belt and pulley guard cover (D) Fig. 30. Speed rates of 80, 120, and 200 feet per minute are available with your band saw. When the belt is on the largest step of the motor pulley (A) Fig. 30, and the smallest step of the gear box pulley (B) the blade speed will be 200 feet per minute. When the belt is on the smallest step of the motor pulley (A) and the largest step of the gear box pulley (B) the blade speed will be 80 feet per minute. When changing speeds, first release belt tension. After the desired speed is obtained, adjust belt tension and close belt and pulley guard cover (D).

SPEED AND MATERIAL CHART

Fig. 31 illustrates the correct speeds and the position of the belt on the motor and gear box pulleys for most common materials cut on the band saw.

BLADE SELECTION

1.Your band saw uses blades 1/2" wide, 64??" long and .020-.025 thick. Accessory blades with a pitch (number of teeth per. inch of the blade) of 10 and 14 are available from Delta.

2.Never use a blade so coarse that less than three consecutive teeth are engaged in the workpiece at one time. (Too few teeth will cause the teeth to strip out).

3.Never use a blade finer than required to obtain a satisfactory surface finish or satisfactory flatness (Too many teeth engaged in the workpiece will prevent attainment of a satisfactory sawing rate; frequently produce "dished" cuts or cuts which are neither square or parallel).

4.When thin rectangular solid bar is to be sawed, the work should, whenever possible, be loaded with the thinnest cross section exposed to the blade teeth. The pitch (number of teeth per. inch of the blade) selected must provide engagement of at least three consecutive teeth in the workpiece. Should application of this rule not be possible because the thinnest cross section is too thin, the piece must be loaded with the wider dimension exposed to the saw teeth and a coarser blade selected.

5.When thin wall pipe or tubing or channel iron are cut, a 14 pitch (number of teeth per inch) blade is used. Fewer than 14 teeth per inch will almost never be satisfactory.For standard wall pipe or tubing 10 teeth per inch is satisfactory.

CHANGING BAND SAW FROM

HORIZONTAL TO VERTICAL

POSITION

Your saw can be changed to the vertical position for notching, slitting or contour work as follows:

DISCONNECT MACHINE FROM

POWER SOURCE.

1.Move the cutting arm to the vertical position and lock in place with the arm positioning lever (C) Fig. 32. Stop screw (A) Fig. 32 should bear against base casting when arm is in the vertical position. If adjustment is needed loosen lock nut (B) and adjust screw (A).

2.Remove two screws (C) and bearing cover plate (D) Fig. 33.

3.Assemble the vertical table (E) to the guide bracket using the two screws (C) that were removed in STEP 2, as shown in Fig. 34.

4.Assemble one end of the table support bracket (G) Fig. 35 to the table using a 1/4-20x1/2" flat head screw and 1/4-20 nut (H) and the other end underneath the guide bracket lock knob (J), as shown in Fig. 35.

CUTTING CURVES

When cutting curves, turn the workpiece carefully so that the blade follows without twisting. If a curve is so abrupt that it is necessary to repeatedly back up and cut a new kerf, a narrower blade, a blade with more set, or additional relief cuts Fig. 37, may be necessary to allow the blade to cut more efficiently. The more set a blade has, the easier it will allow the stock to be turned, but the cut is usually rougher than where a medium amount of set is used.

When withdrawing the piece being cut, changing the cut, or for any other reason, be careful not to accidentally draw the blade off the wheels. In most

Fig. 37

cases, it is easier and safer to turn the stock and saw out through the waste material, rather than try to withdraw the stock from the blade.

LUBRICATING THE VISE SCREW

The vise lead screw should be lubricated using light machine oil as needed.

The drive gears run in an oil bath gear box and it should not be necessary to change this oil more than once a year unless the oil becomes contaminated or a leak occurs due to improper replacement of the gear box cover. To change oil in the gear box, proceed as follows:

DISCONNECT MACHINE FROM

POWER SOURCE.

1.Position cutting arm in the horizontal position.

2.Remove the four screws (A) Fig. 38, and the gear box cover (B) and gasket.

3.Remove the old oil from inside the gear box and replace the oil using 140 weight gear oil, available from Delta. The new oil should just come to the edge (C) Fig. 39, of the gear box. Do not overflow. Replace the gasket, cover and four screws that were removed in

STEP 3.

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 ANSI Z87.1 SAFETY GLASSES

WHILE USING COMPRESSED AIR.

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.
