Excessive blade breakage and/or

teeth ripping from the blade.

Premature blade dulling.

Unusual wear on side or back of

blade.

Motor overheating.

Bad, crooked or rough cuts.

Blade is twisting.

1. Clamp the workpiece securely.

2. Adjust the speed or feed to suit the workpiece.

3. Replace with a finer blade.

4. Use the saw at slower speed and use a smaller tpi blade.

5. Adjust blade tension so that it does not slip on the wheel.

6. Place blade in contact with the workpiece only after the saw has

started.

7. Adjust blade wheel alignment.

8. Adjust blade guide alignment.

9. Use correct thickness blade.

10. Re-weld or replace blade.

1. Replace with a smaller tpi blade.

2. Reduce speed.

3. Increase feed pressure by unscrewing tension bar. This will

decrease the spring tension on the arm.

4. Reduce speed, increase feed pressure.

5. Replace blade and adjust to the correct tension.

6. Increase blade tension.

7. Increase blade tension and reduce speed.

1. Replace blade guides.

2. Adjust guide pivots.

3. Tighten blade guide brackets.

1. Reduce blade tension.

2. Reduce drive belt tension.

3. Use a blade more suitable for the workpiece.

4. Lubricate the gears.

5. Decrease feed and speed.

1. Reduce feed pressure by screwing tension bar in. This will

increase the spring tension on the arm.

2. Adjust blade guides.

3. Increase blade tension.

4. Replace the blade.

5. Adjust the speed.

6. Adjust guide spacing.

7. Tighten the guide assembly.

8. Use a finer blade.

1. Decrease feed pressure.

2. Decrease blade tension.

1. Workpiece is loose in the vice.

2. Incorrect speed or feed.

3. Blade is too coarse.

4. Workpiece material is too coarse.

5. Incorrect blade tension.

6. Blade is in contact with workpiece before

saw is started.

7. Blade is rubbing on the wheel flange.

8. Blade guides are misaligned.

9. Blade is too thick.

10. Bad weld on blade

1. Blade tpi is too high.

2. Incorrect speed - too fast.

3. Inadequate feed pressure.

4. Hard spots or scale on the workpiece.

5. Blade is twisting.

6. Insufficient blade tension.

7. Blade is slipping.

1. Blade guides are worn.

2. Blade guides are misaligned.

3. Blade guide brackets are loose.

1. Blade tension too high.

2. Drive belt tension too high.

3. Blade too coarse or too fine.

4. Gears need lubrication.

5. Blade is binding in the cut.

1. Feed pressure too great.

2. Blade guides are misaligned.

3. Inadequate blade tension.

4. Blade is dull.

5. Incorrect speed.

6. Blade guides are spaced out too far.

7. Blade guide assembly is loose.

8. Blade is too coarse.

1. Blade is binding in the cut.

2. Blade tension is too high.

7. TROUBLESHOOTING

6. MAINTENANCE

6.1.

Clean saw after each operation and smear unpainted surfaces with oil to prevent

rusting. Lubricate vice lead screw (32) as necessary.

6.2. Annually replace gearbox oil (SAE 90) as follows:

6.2.1. With blade arm horizontal remove gearbox cover screws (75), cover (93) and gasket (92).

6.2.2. Place oil container under right hand lower corner of gearbox and then carefully raise saw arm fully to drain oil.

6.2.3. Lower saw arm, remove any remaining oil from gearbox with clean cloths and then refill with fresh oil. Replace cover and gasket.

5.6. CUTTING/FEED PRESSURE

The weight of the cutting arm itself applies pressure to the cutting blade and

therefore to the workpiece. An adjustable spring is attached to the arm and as

the spring pressure is increased the cutting pressure is decreased.

5.6.1. If the saw is making crooked or rough cuts or overheating is occurring it may be

necessary to decrease the feed pressure by turning the chromed adjusting rod in

a clockwise direction as shown in fig.7.

5.6.2. If the saw blade becomes dull quickly it may be necessary to increase the feed

pressure by turning the chromed adjusting rod in an anticlockwise direction as

shown in fig.7.
