Introduction
This manual includes the operating and maintenance instructions for the Wilton 10-inch by 16-inch Cut Off
Band Saw, Models 7020/7040. This manual also includes parts listings and illustrations of replaceable parts.
Operating Instructions
Controls
The operating controls for the saw are provided in a control panel on the left side of the machine. The control panel is mounted on a pivoting tube. The pivoting tube allows the operator to position the control panel in a convenient location.

1. A power-on light is provided on the left side of the control panel. The power-on light indicates when power is connected to the machine.
2. A n emergency stop button is provided on the control panel. The emergency stop button provides a means to rapidly cut off electrical power.
3. The saw motor pushbutton switch starts the saw motor and the E-stop button stops the saw motor.
4. A green pushbutton switch is provided to the right of the emergency stop pushbutton. The pushbutton opens an electro-magnetic valve in the hydraulic cylinder circuit. Opening the valves allows the saw head to move downward and put the saw blade in contact with the workpiece.
5. A red release button on the electro-magnetic valve provides a means to lower the saw head when power to the machine has been disconnected (see figure 4).
6. The rate at which the saw head moves downward is controlled by a hydraulic feed rate control located on the top, rear of the saw head (see figure 3).
7. A coolant pump switch is provided on the electrical equipment box on the back of the machine
Setting Blade Speed
1. The blade speed is controlled by an adjustment mechanism on the right end of the saw. Speed increases when the adjustment knob is turned counterclockwise. Speed decreases when the knob is turned clockwise.
2. A placard on the drive belt guard provides recom mended speeds for various materials.
3. A speed indicator is provided on the barrel of the adjustment mechanism. The indicator provides speed indications in feet per minute and meters per minute. (The meters per minute values are shown in parenthesis on the indicator.)
4. The feed rates on the placard are expressed in meters per minute. The feed rate graduations available on the indicator may not match the recommended feed rate. An approximate speed may therefore be required. For example, to set a speed rate of 25 meters per minute, the indicator would be set about midway between 21 metersper-minute and the 30 meters-per-minute graduations.
WARNING: TO CHANGE SPEED, THE SAW
MOTOR MUST BE OPERATING.
5. Turn the speed adjustment knob to the desired rate setting as determined by the material being cut.

Raising/Lowering the Saw
Head
1. Lift the saw head using the handle on the far left side of the saw head.
2. To lower the saw head, press the green pushbutton on the right side of the control panel.
3. To adjust the feed rate, adjust the feed rate control valve knob on the top of the saw head (see figure
3).
4. To lower the saw head with power off, pull and turn the red knob (manual override) on the electro-magnetic valve (see figure 4).
Controlling the Cut:
Hydraulic Feed Control
The weight of the saw arm provides all the force needed to move the saw blade through the workpiece.
In fact, if the full weight of the arm is allowed to make the cut, rapid blade wear and poor cutting accuracy will result. A hydraulic feed control is provided that gives the operator a means to control the speed and efficiency of cutting.
The hydraulic cylinder is attached between the saw base and the saw head. The hydraulic cylinder resists movement of the saw head in the downward direction.
However, the hydraulic cylinder offers no resistance when the saw head is raised upward.
The amount of downward force can be controlled by using the feed rate control valve. When the valve is opened slightly, the saw head will move downward. The further the valve is opened, the faster the saw head will move downward.
The feed control is adjusted by the operator until the saw is operating efficiently. This is usually determined by observing the chip formation. (See Evaluating Blade
Efficiency for more information on cutting efficiency.)

Evaluating Cutting Efficiency
Is the blade cutting efficiently? The best way to determine this is to observe the chips formed by the cutting blade.
If the chip formation is powdery, then the feed rate is much too light, or the blade is dull.
If the chips formed are curled, but colored — that is, either blue or straw-colored from heat generated during the cut — then the feed rate is too high.
If the chips are slightly curled and are not colored by heat — the blade is sufficiently sharp and is cutting at its most efficient rate.
Blade Selection
The cut-off saw is provided with a saw blade that is adequate for a variety of cut-off jobs on a variety of common materials. A 4/6 vari tooth bi-metal blade
(5674011) and a 6/10 vari tooth bi-metal blade
(5674021) are available from Wilton.
See Setting Blade Speed for the speeds recommended for various materials. These selections, while appropriate for many shop cutting needs, do not encompass the wide variety of blades of special configuration (tooth pitch and set) and special alloys for cutting unusual or exotic materials.
A coarse blade could be used for a solid steel bar but a finer tooth blade would be used on a thin-wall tube. In general, the blade choice is determined by the thickness of the material; the thinner the material, the finer the tooth pitch.

10
A minimum of three teeth should be on the work piece at all times for proper cutting. The blade and workpiece can be damaged if the teeth are so far apart that they straddle the workpiece.
For very high production on cutting of special materials, or to cut hard-to-cut materials such as stainless steel, tool steel, or titanium, you can ask your industrial distributor for more specific blade recommendations.
Also, the supplier who provides the workpiece material should be prepared to provide you with very specific instructions regarding the best blade (and coolant or cutting fluid, if needed) for the material and shape supplied.
Blade Break-in Procedures
New blades are very sharp and, therefore, have a tooth geometry which is easily damaged if a careful break-in procedure is not followed. Consult the blade manufacturer’s literature for break-in of specific blades on specific materials. However, the following procedure will be adequate for break-in of Wilton-supplied blades on lower alloy ferrous materials.
1. Clamp a round section workpiece in the vise. The workpiece should be 2 inches or larger in diameter.
2. Set the saw on low speed. Start the cut with a very light feed rate.
3. When the saw has completed 1/3 of the cut, increase the feed rate slightly and allow the saw to complete the cut.
4. Keep the same hydraulic cylinder setting and begin a second cut on the same or similar workpiece.
5. When the blade has completed about 1/3 of the cut, increase the feed rate. Watch the chip formation until cutting is at its most efficient rate and allow the saw to complete the cut (see Evaluating Blade Efficiency). The blade is now considered ready for regular service.
Work Setup
Securing the Workpiece for
Square Cuts
1. Raise the saw head (refer to Figure 5).
2. Slide the left vise jaw far enough to the left to allow the workpiece to be placed in the vise.
3. Place the workpiece on the work table. If the workpiece is long, provide support at the other end.
It may also be necessary to provide additional downward clamping to hold the workpiece securely on the work table.
4. Turn clamping hand wheel clockwise to clamp the workpiece in position against the fixed (right) vise jaw.
5. After completing the cut, turn the clamping hand wheel counterclockwise and slide the left jaw away from the workpiece.

1. The blade guides are fitted with coolant fittings.
Coolant is provided to the fittings through interconnecting tubing. The coolant is dispensed directly onto the saw blade.
2. Adjust the coolant flow valves on the top, rear of the saw head as required to provide the desired flow.
The flow should be no more than the blade can draw into the workpiece by blade movement.
3. The coolant flow can be stopped in two ways:
1) By using the coolant pump switch on the
electrical equipment box, or
2) By closing the coolant flow valves on the top,
rear of the saw head.
Coolant Mixture and Quantity
The general purpose coolant is a mixture of water soluble oil and water. Mix one part of soluble oil (TRIM
SOL) to ten parts of water (one quart oil, ten quarts of water). Eleven quarts of coolant are required for the coolant pump to operate properly.
There are numerous coolants on the market that are formulated for special applications. Consult your local distributor for details in the event you have a long range production task, or are required to cut some of the more exotic materials.
Adjustments
The efficient operation of the cut-off saw is dependent upon the condition of the saw blade. If the performance of the saw begins to deteriorate, the first item that you should check is the blade.
If a new blade does not restore the machine’s cutting accuracy and quality, refer to the Troubleshooting section (or the blade manufacturer’s guide) for conditions to consider and adjustments that can be made to increase the life of the blade.
To change the blade, refer to Changing Blades in the Maintenance section. To adjust the blade tracking, refer to the following procedures.
Blade Tracking Adjustment
Blade tracking has been tested at the factory. Adjustment is rarely required when the blade is used properly or if the blade is correctly welded. (See figure 10 for location of blade tracking adjustment screws.)
Center

Screws
Figure 10: Blade tracking and tensioning
Factory or Field Procedure
1. Raise the saw head enough to allow the saw motor to operate.
2. Loosen four knobs securing the blade cover. Lift the cover and swing it backward.
3. Remove the blade guard mounted on the left blade guide support.
4. Remove both blade guide bearing brackets.
NOTE: Maintain proper tension at all times using the blade tensioning mechanism.
5. Loosen the center locking screws in all three hex adjustment screws on the blade tensioning mechanism (see figure 10).
CAUTION: WHILE PERFORMING THE FOLLOWING,
KEEP THE BLADE FROM RUBBING EXCESSIVELY
ON THE SHOULDER OF THE WHEEL. EXCESSIVE
RUBBING WILL DAMAGE THE WHEEL AND/OR THE
BLADE.
6. Start the saw. Slowly turn the single hex adjustment screw at the rear of the tracking mechanism to tilt the idler wheel. Do not turn either of the other two adjustment screws. Turn the adjustment screw until the blade is touching the shoulder of the idler wheel.
NOTE: Turning the screw inward causes the blade to move toward the shoulder of the wheel. Turning the screw outward causes the blade to move away from the shoulder.
7. Turn the single hex adjustment screw so the blade starts to move away from the shoulder of the wheel
— then turn the single hex adjustment screw in the other direction so the blade stops, then moves slowly toward the shoulder.
WARNING: KEEP FINGERS CLEAR OF THE BLADE
AND WHEEL TO AVOID INJURY.
8. Turn the single hex adjustment screw to stop the motion of the blade on the wheel as it gets closer to
the wheel shoulder. Put a 6-inch length of paper between the blade and the wheel as shown in figure
11. The paper should not be cut as it passes between the wheel shoulder and the blade.
9. Turn the single hex adjustment screw a small amount.
Repeat the insertion of the paper between the wheel shoulder and the blade until the paper is cut in two pieces.
NOTE: You may have to repeat the check with the paper several times before the blade and the shoulder cuts the paper into two pieces. Do not hurry the adjustment. Patience and accuracy here will pay off with better, more accurate, quieter cutting and much longer machine and blade life.
10. When the paper is cut, turn the hex adjustment screw slightly in the counterclockwise direction. This assures that the blade is not touching the shoulder of the wheel.
11. Shut off the saw.
12. Hold the hex adjustment screws with a wrench and tighten the center locking screws. Make sure the hex adjustment screws do not move while tightening the center screws.
13. Install the two blade guide bearing brackets. Position the guides so the bearings just touch the blade.
14. Install the left blade guard.
15. Close the saw head cover. Tighten all four knobs.
Motor "ON"
Upper Wheel
Rotating should rarely require adjustment. When adjustment is required, adjust immediately. Failure to maintain proper blade adjustment may cause serious blade damage or inaccurate cuts.
It is always better to try a new blade when cutting performance is poor. If performance remains poor after changing the blade, make the necessary adjustments.
If a new blade does not correct the problem, check the blade guides for proper spacing. For most efficient operation and maximum accuracy, provide 0.001
inch clearance between the blade and the guide bearings. The bearings will still turn freely with this clearance. If the clearance is incorrect, the blade may track off the drive wheel.
CAUTION: CHECK THE BLADE TO MAKE SURE THE
WELDED SECTION IS THE SAME THICKNESS AS
THE REST OF THE BLADE. IF THE BLADE IS
THICKER AT THE WELD, THE GUIDE BEARINGS MAY
BE DAMAGED.
If required, adjust the guide bearings as follows:
1. The inner guide bearing is mounted on a concentric bushing and can not be adjusted.
2. The outer guide bearing (closest to the operator) is mounted on an eccentric bushing and can be adjusted.
3. Hold the bushing with a 3/4-inch wrench and loosen

4. Position the bearing by turning the bushing. Set the clearance at approximately 0.001 inch. (The blade should be in a vertical position between the bearings. (See figure 13.)
5. Tighten the center locking screw with an Allen wrench while holding the eccentric bushing in position with the 3/4-inch wrench.
6. Use the same procedure to adjust the other guide bearing.
7. When the adjustment is correct, the guide bearings should rotate freely with slight pressure of the finger (with the blade stopped).
8.Adjust blade-edge bearings so they just touch the back edge of the blade (see figure 19).
Test Cutting to Verify
Adjustment Accuracy
Test cuts can be used to determine whether or not you have adjusted the blade accurately. Use 2-inch round bar stock to perform these test cuts, as follows:
1. With the bar stock securely clamped in the vise, make a cut through the bar stock. (See figure 14.)
2. Mark the top of the bar stock.
3. Move the bar stock about 1/4-inch past the blade so you can begin a second cut.
4. Rotate the bar stock 180 degrees so the mark you made is now at the bottom of the cut.
5. Make a cut through the bar stock.
6. Use a micrometer to measure the thickness varia-
1. Clamp in vise and mark top of barstock here
2. Cut off a slice of the bar stock tion of the disk you have cut from the bar stock. Measure at the top and bottom of the disk.
The saw blade can be considered correctly adjusted when the variation measure is no more than 0.012 inch across the face of the disk.
If you do not have a piece of 2-inch bar stock available for a test cut, use a larger diameter test piece rather than a smaller one. The maximum thickness variation on any test piece should be no more than
0.003 inch, per side, per inch of stock diameter.
Adjustment of the Limit
Switch
1. The limit switch is provided to shut off the saw motor when the workpiece is cut through.
2. To set the limit switch, loosen the jam nut on the limit switch stop (figure15).
3. Adjust the stop as required and retighten jam nut.

Machine Setup
The saw delivered to you has been adjusted at the factory. A number of test pieces have been cut using the saw to verify the accuracy of cutting. Therefore, the only setup operations required before releasing the saw for service are spotting the saw and establishing the electrical connections to the motor.
Uncrating and Spotting
Spot the saw where it makes the most sense for the operations you will probably be doing. If you are going to be doing cut-off work on very long pieces of stock, allow plenty of room for the stock, and the infeed and outfeed supports. Remove the saw from the shipping skid and discard any hold-down devices that were used to secure the saw to the skid.
