maintaining tapered filter on first stage

[jimmys]

I have a mares V32 first stage and the filter is a little rusty (green particles). I wanna change it by myself. does anyone has the pdf file for all first stage service manual?
thanks
I found the file just now

my dive shop instructor wants me to turn my reg in for service, but i dun wanna pay servicing fees since i have just had this reg for a few months. Is there anything I should be careful with when changing the filter?

I'd be concerned with where the green particles came from.

there is actually corrosion. apparently I did not fasten my dust cap (on the first stage) as tight as i can so some water got in and caused the filter to corrode.
I just neeed some advice on how to actually change the filter by myself. If i can't, i guess i ll just leave it for servicing.
but thanks for your imput buddy

There's a snap ring that must be removed, then the filter comes right out. If you need a new one, they come in the 1st stage maintenance kit.

you may be able to soak it in vinegar or something, it may just be corrosion

probably best to find a clean new one

In that case, your tech is probably correct. If the corrosion on the filter is from water in the 1st stage, them it surely also penetrated further in. As long as the filter is stopping dirt and passing gas, it is not a big problem. But corrosion on sealing surfaces inside the 1st stage can be a problem.

thats awsome. i guess there isn't really much difficulty to replace that filter. my first stage did not come with a kit, where else would i get one? any diveshop?

*Most* dive shops won't be willing to sell you a kit, though some may sell you just the filter.
As already mentioned, if you have corrosion on the filter it may well be cause for concern that saltwater isn't making mischief inside your 1st stage.
See: ComDive's ScubaStore for Mares kits.
They're one of the few reg mfgrs that allow kit sales to the owners.

hey bob, are you saying that besides the filter, inside of my first stage is also corroded?
btw, the filter is not universal is it?
