I put that because i do not know where to put this, anyways i bought a bike pump today its a serfas fp-100. i can't seem to get the schrader valve in the hole. (it has 2 holes, 1 for presta, one for schrader) I havnt tried the presta one yet because i got no tubes for that. Why doesnt it go in the hole??

for the schrader 1? Do i need to do something to it?

(im having this same problem with another pump)
