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

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).

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. MATERIAL CUTTING CHART

BLADE SELECTION

1. Special note: 1(1/2’’ x 0.025’’x 641/2min, 651/2max) 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

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:
