blade. The operator shall not wear gloves when operating the machine.

2. All doors shall be closed, all panels replaced, and

other safety guards in place prior to the machine being started or operated.

3. Be sure that the blade is not in contact with the

workpiece when the motor is started. The motor shall be started and you should allow the saw to come up to full speed before bringing the saw blade into contact with the workpiece.

4. Keep hands away from the blade area. See

Figure A.

5. Remove any cut off piece carefully while keeping

your hands free of the blade area.

6. Saw must be stopped and electrical supply must

be cut off before any blade replacement or adjustment of blade support mechanism is done, or before any attempt is made to change the drive belts or before any periodic service or maintenance is performed on the saw.

7. Remove loose items and unnecessary

workpieces from area before starting machine.

8. Bring adjustable saw guides and guards as close as possible to the workpiece.

9. Always wear protective eye wear when operating, servicing, or adjusting machinery . Eyewear shall be impact resistant, protective safety glasses with side shields complying with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection. See Figure B.

10. Nonslip footwear and safety shoes are recommended. See Figure C.

1 1. Wear ear protectors (plugs or muffs) during

extended periods of operation. See Figure D.

12. The workpiece, or part being sawed, must be securely clamped before the saw blade enters the workpiece.

13. Remove cut off pieces carefully , keeping hands away from saw blade.

14. Saw must be stopped and electrical supply cut off or machine unplugged before reaching into cutting area.

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.

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.

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 cross-

section 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 4: Clamping methods for various crosssections of stock

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, JET'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.

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.
