Model G0806/G0807 (Mfd. Since 12/15)
Possible Solution
1. Reduce feed rate/decrease blade TPI.
2. Adjust blade tracking (Page 23).
3. Install new blade, and regularly remove tension
from blade when not in use (Page 23).
4. Replace blade, re-secure the workpiece from
shifting.
5. Replace or dress rubber tire(s) (Page 46).
6. Increase blade tension (Page 23).
7. Adjust blade guides (Page 25).
8. Install correct blade for machine (Page 34).
9. Tighten the blade guide as close to the workpiece
as possible.
10. Clean metal chips from wheels.
1. Reduce the feed rate.
2. Feed workpiece straight into the blade.
3. Install a blade with more suitable TPI or different
style of teeth.
4. Reverse blade if necessary.
5. Replace blade (Page 34).
6. Install a smaller width blade.
7. Adjust blade speed as required.
8. Adjust the blade tracking (Page 23).
Possible Solution
1. Repair wiring or replace grinder switch.
2. Replace grinder motor.
1. Replace bulb, repair wiring (Page 55); replace
switch.
2. Replace transformer.
1. Use welder as outlined in operations section and
practice on scrap blades (Page 38).
2. Repair wiring or replace welding switch (Page 55).
3. Replace welder transformer.
1. Remove debris, oily substances, or flash from weld
clamps and blade.
2. Use blade shear to cut blades; grind ends together.
3. Make sure blade ends are evenly butted against
each other before securing with lock levers.
4. Set clamping pressure correctly (Page 39).
1. Make sure blade ends are evenly butted against
each other in clamps; use correct clamping
pressure (Page 39).
2. Use blade shear to cut blades; grind ends together.
1. Correctly perform annealing procedure (Page 40).
2. Only grind flash even with blade body.
3. Make sure clamps and blade ends are clean of
debris, oily substances, and flash.
