Remove WakeCrosser™ rubber tube and cover from packaging. When preparing to inflate the tube, spread the cover bottom out as evenly as possible. Place the deflated rubber tube inside the cover. Make sure the lower front Velcro™ support is flat against the bottom of the cover, and the upper support is over the top of the tube to allow for inflation without obstruction. It is important that the brass cap speed-valve on the tube be positioned at the front of the tube cover, preventing the user from leaning against the valve. Pushing the rubber tube against the outer side-walls of the cover before, and during inflation enables the tube to expand consistently within the cover.

Inflate the rubber tube using an air mattress pump, portable blower, or shop vacuum so it appears snug and taut within the tube cover. Make sure to tightly secure the WakeCrosser™ speed-valve using your hands. The valve will not lose air if tightly secured. Tube and cover will be firm, and wrinkle free after proper inflation with approximately 2 lbs. PSI displacement. Do not over-inflate the rubber tube to the point of creasing or buckling. If over-inflating occurs, loosen the brass cap to release air until the tube is round and not distorted. Improper inflation causes major problems with tube performance, safety, and longevity. An under-inflated tube can carry and hold water, inhibiting its ability to ride properly on the water.

Before attempting to use the WakeCrosser™, make sure the ski-rope is affixed to both D-Rings of the wake-crossing harness. Standard rope lengths are 50-60 ft, with a minimum tow capacity of 2500 lb. (1136 kg.) The average tensile strength for towing a single person is 2375 lbs. (1070 kg). When not using your WakeCrosser™ tube it is important to store the tube out of the sun and in a cool environment. If the tube is left in the sun for any length of time, it could expand and become deformed. The tube may need additional air added before using when stored in a cool area.

For tube longevity, it is ideal to leave the tube inflated inside the cover in an area where exposure to sunlight and air circulation is minimized. Avoid additional sources of ozone such as electric motors or equipment. Petroleum based materials should never be allowed to come in contact with the tube.

If there is no available storage space, inner tubes should be stored without sharp creases in the rubber. Do not tightly vacuum the tube. It is recommended to store tubes in a black plastic bag with the top tied or sealed, away from the noted sources of ozone.

To deflate inner tube, remove the brass end cap by hand. Use a tire valve tool to loosen and remove the inner valve stem core. Remove the tube from cover, fold and curl as necessary to remove excess air. Once the inner tube is deflated, reinstall the valve stem core and tighten securely using the tire valve tool. Finally, fasten the brass end cap for storage.

Note: Tube may naturally deflate due to seasonal air pressure changes. Additional air may be required before use.

**When re-inflating inner tubes, ensure the inner valve stem core is screwed in as tight as possible.**
