SAFETY

1. Know your band saw. Read the operator

’s Manual carefully. Learn the operations, applications and limitation.

2. Use recommended accessories. Improper accessories may be hazardous.

3. Wear proper apparel.

4. Keep unnecessary people away.

5. Don

’t overreach or stand on tool.

6. Avoid dangerous environment. Don

’t use band saw in damp or wet locations. Keep work area well lighted.

7. Keep work area clean. Cluttered and slippery floors invite accidents.

8. Remove adjusting keys and wrenches from band saw before turning on power.

9. Avoid accidental starting. Mark sure switch is off before plugging in power cord.

10. Don

’t force band saw. It is safe to operate at the cutting rate for which it was designed.

11. Be specially careful when using band saws in vertical position to keep fingers and hands out of the path of blade, both above and beneath the table.

12. Never hand hold the material with saw in horizontal position. Always use the vise, clamp securely.

13. Keep belt guard and wheel covers in place and in working order.

14. Support long, heavy work from the floor.

15. Always remember to switch off the machine when the work is completed.

16. Disconnect power cord before adjusting. Servicing and changing blade.

17. Check damaged parts. Damaged parts must be replaced or repaired.

18. Moving parts should keep in alignment. All adjustments are to be made with power disconnected.

19. Use a sharp blade and keep tool clean for best and safest performance.

20. Safety is a combination of operator

’s common sense and alertness at all times when the saw is functioning.

21. Keeping the band saw in top condition is essential for safety.

BLADE GUIDE BEARING ADJUSTMENT

This is the most important adjustment on your saw. It is impossible to get satisfactory work from your saw if the blade guides are not properly adjusted. The blade guide bearings for your Metal cutting Band saw are adjusted and power tested with several test cuts before leaving the factory to insure proper setting. The need for adjustment should rarely occur when the saw is used properly. If the guides to get out of adjustment, it is extremely important to readjust immediately. If proper adjustment is not maintained, the blade will not cut straight and if the situation is not corrected, it will cause blade damage.

Because guide adjustment is a critical factor in the performance of your saw, it is always best to try a new blade to see if this will correct poor cutting before beginning to adjust the bearings. If a blade becomes dull on one side sooner than the other, for example, it will begin cutting crooked. A simple blade change should correct this problem-the more difficult guide adjustment will not.

If a new blade does not correct the problem, check the blade guides for proper spacing.

There should be 0.001’’ clearance between the 0.025’’ thickness blade

3

and guide bearing. To obtain this clearance adjust as follows:

1. The inner guide bearing is fixed and cannot be adjusted.

2. The outer guide bearing is mounted to an eccentric bolt and can be adjusted.

3. Loosen the nut while holding the bolt with a wrench.

4. Position the eccentric by turning the bolt to the desired position of clearance.

5. Tighten the nut

6. Adjust the second blade guide bearing in the same manner.

7. The back edge of the blade should just touch the lip of the Blade Guide

Bearing.

BLADE GUIDE ASSEMBLY ADJUSTMENT

The Metal Cutting Band Saw is equipped with two adjustable blade guide assemblies. This feature will permit you to adjust the position of the blade guide for various widths work pieces.

To effect the most accurate cut and prolong the life of the blade. The blade guide assemblies should be adjusted to just clear the piece to be cut. This is done as follows:

1. Place the work piece in the vise of band saw and clamp tightly.

2. Adjust catch blade guide assembly to the desired position by loosening the hand knobs and positioning the guides required.

3. Tighten the hand knobs.

ADJUSTING BLADE TENSION

1. Make sure the motor is shut off.

2. Press the blade lightly with left hand, make the rear blade against the flange of blade wheel and test the blade tension.

3. Adjust the blade tension adjustable knob with the Figure (1) Adjusting Blade Tension right hand until the blade obtain the proper tension.

CHANGING SPEED

1. When using your Band Saw, always change the blade speed to best suit the material being cut. Cutting chart is shown in figure (2).

4

2. Cut off power. Open the pulley guard cover. Loosen the lead screw

(#98), you are now able to change the position of the belt to gain the desired speed. Check the belt tension as instructed before. When the tension the belt is well adjusted, lock the motor firmly. Close the pulley guard cover.

2 max) tooth per inch general use blade is furnished with the metal cutting Band Saw.

Additional blades in 10 and 14 tooth sizes are available.

2. The choice of blade pitch is governed by the thickness of the work to be cut; the thinner the work piece, the more teeth advised. A minimum of 3 teeth should be in the work piece at all times for proper cutting.

3. If the teeth of the blade are so far apart that they straddle the work, server damage to the work piece and to the blade can result.

CHANGING BLADE

Raise saw head to vertical position. Loosen blade tension adjustable knob sufficiently to allow the saw blade to slip off the wheels. Install the new blade as follows:

1. Place the blade in between each of guide bearing.

2. Slip the blade around the motor pulley (bottom) with left hand and hold in position.

3. Hold the blade taut against the motor pulley by pulling the blade upward with the right hand which is placed at the top of the blade.

4. Remove left hand from bottom pulley and it s the top side of the blade to continue the application on the upward pull on the blade.

5. Remove right hand from blade and adjust the position of top pulley to

5

permit left hand to slip the blade around the pulley using the thumb, index and little finger as guides.

6. Adjust the blade tension knob clockwise until it is just right enough so no blade slippage occurs. Do not tighten excessively.

7. Place 2-3 drops of oil on the blade.

8. Replace the blade guard.

ADJUSTING THE BLADE TRACKING

This adjusting has been completed and power-tested at the factory. The need for adjusting should rarely occur when the saw is used properly. If the tracking goes out of adjusting is listed below:

Step 1: Turn simultaneously with adjusting set screw to make the blade track against the shoulder of the pulley.

HORIZONTAL CUTTING OPERATION

Before operating, please read instruction manual and examine every part including speed, Blade selection, guide assemble position, etc. Operation is as follows:

WORK SET UP

1. Raise the saw head to the vertical position.

2. Open the vise to accept the piece to be cut by rotating the wheel at the end of base (counter clockwise).

3. Place the work piece on the saw bed. If the price is long, support the end.

4. Clamp the work piece securely in the vise by rotating the hand wheel clockwise.

6

CUTTING

Close switch, letting the head down slowly onto the work, Do not drop or force. Let the weight of the saw head provide the cutting force. The saw automatically shuts off at end of the cut.

Method of adjusting blade:

A. Loosen the screw #11.

B. Adjust the blade adjustable seat #64 to make the blade vertical to bed.

C. Place the square on the bed to check if the blade is vertical, if not, repeat the process A to C.

D. Tighten the screw #11.

LUBRICATION

Lubricate the following components using lubricant, L-HV32

1. Ball bearing

–none.

2. Blade guide bearing-none

3. Driven wheel bearing-none.

4. Vise lead screw- as needed.

5. The driven gears run in the bath and will not require a lubricant change more than then once a year. When needing a change, first put down the bead to a Horizontal position, then loosen 4 screw (#75) of the gear box open the cover (#93). Placing a pan under the tight lower corner of the gear box, slowly raise the head until the oil flows out, Lower corner of the gear box, slowly raise the head until the oil flows out, Lower head.

Then wipe up excess oil and foreign matter with soft rags. Then add lubricant into the box until it is full and not flow over. Close the cover, tighten 4 screws.
