The buoyancy tube is made of HYPALON (Du Pont registered trademark) coated fabrics.
The buoyancy tube of the boat has of five independent airtight compartments. Each compartment has an inflation valve.

INFLATION / DEFLATION OF THE BUOYANCY TUBE.
Before inflation it's necessary to set all valves in operating condition. For it open the valve cap 1 (Fig.4), press
spindle 4 (Fig.4) with your finger and rotate it clockwise until the spindle will be fixed in upper position.
Fill the tube with air using the pump from the complete set. First fill two rear compartments, next two middle
compartments. However, do not increase the pressure up to its nominal value (the tube will be completely straightened).
After that, fill the front compartment up to the nominal pressure. The nominal pressure value is 0.2 bar (2.9 psi). Fill the
remaining compartments with air to the nominal pressure. Having completed filling, close the valves caps 1 (Fig.4).
In order to discharge air from the tube compartments, open the valve cap, press spindle 4 (Fig. 4) with your finger
and rotate it anticlockwise until the spindle will be fixed in lower position.
