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.
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.
7. TROUBLESHOOTING
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.

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.
