Troubleshooting
Possible Solution
1. Reduce wheel pressure.
2. Clean and protect all wheel surfaces (Page 28).
3. Replace wheel (Page 18).
1. Use a consistent and smooth tracking pattern that
overlaps with each back-and-forth pass (Page 21).
2. Start with least amount of pressure, then gradually
increase pressure when curve stops forming
(Page 20).
1. Reduce wheel pressure.
2. Replace wheel bearings.
1. Use a lower wheel with a larger radius (less crown).
1. Start with lower wheel of largest radius (least curve)
and work up to correct radius for operation.
1. Start with least amount of pressure, then gradually
increase pressure when curve stops forming
(Page 20).
2. Use lower wheel(s) with a radius (crown).
1. Use sheet metal of appropriate thickness (Page 5).
2. Use a lower wheel with a higher crown.
3. Increase pressure on workpiece.
1. Lubricate quick-release hub components (Page 28).
2. Lubricate quick-release hub components (Page 28).
