Setup
Inflation Instructions
- Unfold the snow tube on a clean, flat surface.
- Locate the double locking valve on the snow tube.
- Open the outer cap of the valve.
- Insert the nozzle of the manual air pump into the valve. Ensure a snug fit.
- Begin pumping air into the snow tube until it is firm to the touch but not overinflated. The tube should have some give to absorb impacts.
- Once inflated, quickly remove the pump and close the inner plug, then secure the outer cap to prevent air leakage.

Maintenance
Cleaning

Storage

- Once fully deflated, fold the snow tube into a compact size.
- Store the snow tube in a cool, dry place, away from direct sunlight and sharp objects.

Troubleshooting
Snow Tube Does Not Hold Air
- Ensure both the inner plug and outer cap of the double locking valve are securely closed after inflation.
- Check the valve for any debris that might prevent a proper seal.
- Inspect the entire surface of the snow tube for punctures or tears. Small punctures may be repairable with a patch kit (not included).
Snow Tube Does Not Slide Well
The snow tube's exterior is made from durable polyester oxford fabric. Optimal sliding performance is typically achieved on well-packed snow or icy surfaces. On loose or fresh powder, the tube may require more effort to move or may not slide as freely.
