Issues with my new Hammer 7... Oring, cup seal, velocity.

Hi guys,

Just got a new Hammer 7 and had / still have issues. Just woundering if any of you had seen or experienced stuff like this...

Everything in package was good and first look at product was impressive for the price range.

Got the air on and it started leaking right away. I would assume that there is a air test before it leave?

Took it apart, noticed right away the the front oring was chewed with part of it sticking out of the thread. But, there is a spare one in the kit... ok should I say there was a spare o-ring.

Retest everything but still leaking. Took the booklet and start reading. Ok, now it's pointing cup seal. There it was, plyer makes on the cup seal. Again, replaced it with the spare one in the kit. Oiled everything good and there it was... Held air.

Off to local field to chrono everything. Dang, the marker is not moving past 210-215. Worked the velocity up and down, figured that it might be like some other markers that there is issues with velocity past a point it's going back down.

So, any Kingman/Spyder guru can help me with this? Should I contact Kingman to sort this out. Any input would be greatly appreciated.
Thanks,

Did you use any locktite on the replacement cup seal?

Hit me up at lmartin@kingman.com, will replace the parts you used out of the box.

Your chrono is low because you are using a HPA tank that is on the low side of High Pressure. Take the tank to your local shop and ask them to get it up to 750 at least.

My Ninja was putting out 650 and got me 210 max.

No, I did not add anymore loctite as I could see the red one still there in quantity. Should I add more? I'm not a big fan of Loctite.

I will get my tank checked.

Thanks for the fast reply guys.

Cheers,

Dont use red loctite..pretty much ever
I didnt have any on my at 1st but seeing as it was metioned frequently here on the forum I used a dub of purple loctite(low strength\hobby grade)
Havent had any velocity issues even straight out of the box except when I switched between FS and balls,seems FS shoot about 20+fps higher

Having a similar problem here. Air was leaking, played all day with it, didn't hurt it, but I'd like to fix it. Siliconed my cup seal, after replacing the one in the marker with one in the parts kit. Still leaking. So this front o ring is what needs replacing? How do I go about getting to that?

Hillbilly,
I assume that it's still with the cup seal area as the air is not going further down until you actually pulled the trigger. But again, I'm no expert.

Cheers,

I had an issue with mine leaking down the barrel out of the box. I replaced the cupseal with the one that came in the parts kit and the leak is now gone. When I took out the internals the cupseal that was there just about fell off as it wasn't threaded on completely. I tightened it up and to see if that would stop the leak but I ended up having to replace the cupseal anyways.

Well I already replaced the cup seal once, and this time I used silicone to seal it up real nice. When I take out my ASA, the cup seal is still very sealed, it can't get any more threaded. So I figured it wasn't the cup seal, but it sounds like I may be wrong. So I should PM Lou for another replacement cup seal?
