Clamping materials in the saw vise

Refer to Figure 1.

1. Lift the saw arm to its full up position.

2. Lock the arm up using the hydraulic feed control valve.

Note: Use the handle on the arm to lift the arm. Never use any other part of the arm as a lifting method.

3. Open the left vise by turning the vise handwheel counterclockwise.

4. Adjust the vise jaws for the appropriate cutting angle, if required. See sections on Right angle

cutting and Angle cutting.

5. Put the work piece material between the vise jaws.

Note: If the work piece material is long, support both the ends of the material as needed to keep the material level on the saw base.

6. Turn the vise handwheel clockwise until the work piece is securely clamped in the vise.

7. Proceed to cut according to instructions in

Cutting procedure.

Right angle cutting

Refer to Figures 1 and 2.

If you want to be certain the workpiece is being held in the vise at exactly 90 degrees to the blade for cutoff work, use the following procedure to check the blade-to-jaw angle.

1. Disconnect the saw from its electric power source.

2. With the saw arm in its fully lowered position, place a machinist's square,or a machinist's protractor 90 degrees, against the saw blade and right vise jaw. If the jaw is square to the blade, then no adjustment is required.

3. If adjustment is required, see Angle Cutting. The procedure for setting the jaw angle with respect to the blade is described in that section.


Angle cutting

Refer to Figure 2.

1. Loosen the right jaw pivot and lock bolts.

2. With the arm in its fully lowered position, and using a machinist's protractor between the saw blade and right vise jaw, set the angle of the right jaw to the required angle.

3. Tighten the pivot and lock bolts.

4. Lift the saw arm to its full up position and lock it up using the hydraulic feed control knob.

Note: Use the handle on the arm to lift the arm.

Never use any other part of the arm as a lifting method.

5. Loosen the left jaw lock bolt.

6. Use the handwheel to move the left jaw until it touches the right jaw firmly.

7. Snug the left jaw lock bolt. Both vise jaws are now the correct angle for the required cut.

Note: There is a scale on the back of the saw table which allows you to set up for angle cuts without using a protractor. See Figure 3.

These angles should be considered approximate, and the protractor method should be used where higher accuracy is required.

Figure 3: Using the scale on the rear of the saw base to set the jaws for angle sawing. Where the edge of the right jaw crosses the scale an approximate angle cut can be made to the indicated number of degrees on the scale.

Clamping methods

The method for clamping different crosssection work pieces is shown in Figure 4.


Figure 2: Using a protractor to set the vise jaws at desired angle. By setting the protractor to 90 degrees, or using a machinist's square, the jaws can also be set square with respect to the blade.

Figure 5: Setting the stock stop cutoff length

Using the stock stop

When cutting a number of identical pieces, the use of the stock stop can speed operations.

Refer to Figures 1 and 5.

1. Disconnect the saw from its electric power source.

2. With the arm in its fully lowered position, loosen the stock stop set screw.

3. Slide the stock stop to the required distance from the blade.

4. Rotate the stock stop so the stop is at the lowest possible position for stopping the work piece at the required distance. This will help prevent any binding between the work piece and blade when the cut is completed.

5. Tighten the stock stop set screw securely.

6. For best accuracy, make a test cut on a piece of scrap material to verify the length of cut using the stock stop.

Blade selection

The saw is delivered with a blade adequate for a variety of jobs on a variety of common materials.

However, Wilton's blades, while appropriate to many shop cutting needs, don't begin to exhaust the wide variety of special blades available for special cutting jobs.

For high production cutting of special materials, or for hard-to-cut materials such as stainless steel, tool steel, titanium, etc., ask your industrial distributor for more specific blade recommendations.

Material Speed

Steel shapes and low carbon steel 125

Medium and high carbon steel

Cr-Moly steel

Chromium steel

Tool steel

Figure 6: Blade speeds and belt positions

Changing blade speeds

1. Refer to Table 1 for recommendations on blade speed for various materials.

Note: These are approximate speeds.

Different alloys and section materials and the use of cutting fluid may require other speeds.

Check you machinists' handbook, or ask for recommendations from your blade, cutting fluid or work piece suppliers for specific recommendations on specific material.

2. Disconnect the saw from its electrical power source.

3. With the arm in its fully lowered position, remove the pulley cover lock screw and open the pulley cover. Refer to Figure 6 for speeds and belt positions.

4. To change the belt position (and, therefore, the blade speed) first loosen the motor plate adjustment lock nut. Refer to Figure 8 for the position of the motor plate adjustment screw and locknut.

5. Turn the adjustment screw counterclockwise until the belt can be move to the pulley position required.

6. Turn the adjustment screw clockwise to tension the belt until there is 1/2 inch of play in the belt as shown in Figure7.

7. Tighten the adjustment lock nut.

8. Close the pulley cover and secure it shut with the lock screw.

9. Reestablish electrical power to the saw and proceed with cutting.

Evaluating cutting efficiency

Is the blade cutting efficiently? The best way to tell is by observing the chips formed by the blade as it cuts.

If the chip formation is powdery, then the feed is much too light or the blade is too dull.

If the chips formed are curled, but straw or blue colored, then the feed rate is too high.

If the chips formed are curled but not colored, then the blade is sharp enough and cutting at an efficient rate.

Cutting procedure

1. Never start a cut with the blade resting on the work piece.

2. Be certain you knock off the sharp corners of any work piece material which might damage the blade. See Figure 4.

3. Have the motor ON and running at full speed before lowering the blade into the cut.

4. Use the hydraulic control valve to feed the blade into the work piece.

5. If you use a cutting fluid, turn the valve on before beginning the cut.

Using the hydraulic feed control

Refer to Figure 9.

The hydraulic feed control cylinder is a "single action" hydraulic cylinder. This allows you to lift the arm at any time, easily, but controls the downward movement of the arm using a valve on the top of the cylinder.

When the control valve is turned fully clockwise the cylinder is "locked" and the saw arm will not move downward. You can lock the arm, using the valve, at any position in its travel. This allows you to lock the arm in its up position for operations which require it. And it allows you to lock the arm in positions which allow you to adjust work piece length, etc.

Most important, use of the valve allows you to begin any cuts "gently," which can greatly extend the life of the blade. Simply open the valve slightly to begin the cut, then open the valve to effective cutting feed. See Evaluating cutting efficiency.

The valve is also important when breaking in any new blades. See Blade break-in procedures.

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. You may want to consult manufacturers' literature for breakin of specific blades on specific materials. However, the following break-in procedure will be adequate for break-in of Wilton supplied blades.

1. Clamp a 2 inch or larger work piece in the saw.

2. Set the blade speed to its required speed. See

Changing blade speeds.

3. If possible, use a cutting fluid during break-in cuts.

4. Set the hydraulic control valve just enough to begin a very light cut on the work piece.

5. When the blade has cut 1/3rd of the way through the work piece, increase the feed rate slightly and allow the blade to complete the cut.

6. Make another cut on the stock. Begin the cut with the control valve set at the same feed rate you finished the first cut.

7. 1/3rd of the way through the second cut, increase the rate of feed until the blade is cutting at its most efficient rate. See Evaluating cutting


8. Allow the saw to complete this second cut. The blade can now be considered ready for regular service.

Note: There are flanges on the back face of the drive and idler wheels to prevent the blade from "walking off" the back of the wheels. If these flanges are damaged the wheels must be replaced. Check blade tracking whenever changing a blade to be certain the blade is positioned correctly on the wheels. See Blade tracking in the

Maintenance section of this manual.
