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.

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.
6.1. Clean saw after each operation and smear unpainted surfaces with oil to prevent rusting.
6.2. Annually replace gearbox oil (SAE 90) as follows:
6.2.1. With blade arm horizontal remove gearbox cover screws (16), cover (78) and gasket (77).
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.
6. MAINTENANCE
5.5. Blade tracking
Adjustment of the blade tracking is necessary to prevent the blade from twisting or coming off the blade wheels. This adjustment
should be made whenever a new blade is fitted (see para. 5.4.).
5.5.1. Run saw for a short time and then switch off.
5.5.2. Raise saw arm, remove blade cover and check blade-to-wheel relationship (tracking). Rear edge of blade should be very close to, but
not hard against, the wheel flanges.
5.5.3. If inspection indicates that adjustment is required reduce blade tension (see para. 5.1.) and loosen the set screw (65) in driven wheel
(67).
5.5.4. Move drive wheel in or out on shaft as required to improve tracking and tighten set screw.
5.5.5. Having made a small adjustment, tension blade, replace the blade cover, lower the arm and run the saw for a short time.
5.5.6. Switch saw off, remove blade cover and check tracking. Repeat adjustment procedure if necessary.
