I have a little blower running on 4×D battery and it just time saving and also space saving. Vacuum the unit before storage will help you fold this thing in just second too!!The pump is to adjust pressure or inflate a bit. Or without good working battery...But always my pump with me. I figure better have a pump in case of puncture. Duck tape saved the day for me.. Life on the water is very fun and affordable. Lets get on adventure!

Az mindig az adott víztől függ. Ha nagyon sekély, akkor értelemszerűen a kicsit tettem fel. Mivel ez a kajak nagyon könnyű, így minden evezőhúzásra azonnal irányváltással reagál, akár a kicsi, akár a nagy van alatta.

[@upstreamer1661]

Szia. Most vettem én is egyet. Próbálom összerakni, de a két oldalsó szelep valamiért nem akar lezárni miután felfujtam és leveszem a fúvókát. A padló kamrát sikerült felfújni és lezárni, a nyomás is jó, de elsőre az is vacakolt. Megnyomkodtam az ujammal és mintha hallottam volna egy klikk hangot és aztán másodjára nem eresztett le. Mit csinálok rosszul? Megköszönném, ha tudnál segíteni. Köszi.

[@upstreamer1661]

Oké sikerül végre. A szelep rugó fölött lévő fekete műanyag szelepfejet, jobb megfogalmazást nem tudok, el kell valamelyik irányban egy kicsit forgatni. És akkor aktiválódik úgymond a rugósszelep, azaz automatikusan lezárja magát, amikor eltávolítjuk a fúvókát a felpumpálás után. Még egy kérdés, mert van szerencsém cseh használati, összeszerelési utasításokat. Kaptunk egy műanyag kulcsot is, ami ugyancsak ezekhez a szeleoekhez kell,... mintha. Pontosan mire adtak azt a kulcsot? Nekem úgy tűnt, mintha a szelepházak szorítására kellenek, de nem vagyok benne biztos.

[@gaborszabo274]

@@upstreamer1661 Örülök, hogy sikerült megoldani a szelep kérdést. Ezek szerint a működése már világos. A kulcs is a szelephez való. Ezzel lehet kicserélni, ha tönkre menne, de ha jól használod, tovább tart, mint a kajak. Tehát, jó helyre tedd, hogy 5 év múlva is megtaláld, ha majd kell. :)

I took the paddle holder off a broken children's boat and glued it on.

Hi! I like your set up. I was wondering if you are happy with your transducer placement, or if you get too much turbulence / interference with the paddle stroke? I’m thinking of placing mine in a similar location. Thanks!

I did not experience any problems in operation.
