Disassemble and reassemble a Mares pneumatic speargun 

Awesome to hear it helped! Glad to hear the issue with your pneumatic was so simple!

Thanks for the kind comment Louis, glad the video was useful!

Awesome, glad to hear it!

I did put up another video once I received the o-rings. It repeats some of the stuff from this video, but should be helpful. Check it out here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-M2-lFZEaP4E.html

@@AlexanderGaos Just saw it, thanks! I ordered my O-ring set from somewhere far away. Going to take my band gun out tomorrow morning. Thanks again for the great vids.

I actually misspoke in the video, the company I used was SubLub (www.sublub.nl/en) out of the Netherlands. They were great and had good communication. The other company I've seen mentioned is Edosub (www.edosub.it), but I have no direct experience with them. Good luck. By the way, I received the O ring kits for two of the guns and successfully installed them. Both guns are working great...I'll post another videos with some of the tricks I learned during that process soon

I actually haven't been using pneumatic guns for that long, so probably not the best person to do the "storage video". I would like to watch it myself!

@@AlexanderGaos thanks for the answer anyway !

Hey mate, my cyrano 1100 gun is 12 years old. I use it maybe 6-10 times per year. Mainly for coral trout fishing. I have never serviced and never de-pressurised for storage and it is still going strong. Having said that, my previous cyrano 1100 blew the end of the muzzle off under water. I should have fixed it as the muzzle was failing but that was 20 years ago before ebay and amazon had everything available and youtube to train :)

Bummer to hear about this issue. A couple of things come to mind, but what I feel might be the most likely reason based on the fact that you said it just started recently (assuming the gun wasn't dropped or anything) is that the horizontal pin inside the gun on which the trigger mechanism is mounted (and rotates upon) could be gummed up...if the oil is old and combines with old o-ring debris, I could totally see that happening. Not sure why wiggling the loader would solve that however. The good news is that would be a simple fix...just open the gun and clean it! Just a word of warning though...if your o-rings are old, perhaps they might get damaged when you take it apart and could have problems resealing when you reassemble, so be careful. However, given it is jamming, I'd say remove the trigger and the handle and check it out...it's pretty easy...just follow the steps in the video. Shortly after making this video I actually replaced all the o-rings in an old Cyrano 1100 (using pretty much the same steps I outlined in this video and my other video outlining the o-ring replacement process) and it now works great...it's now my regular dive gun actually. Hit me up if you decide to do it and if you run into any issues...and more importantly, let me know if you fix it! One other thing that comes to mind, but would seem much less likely is that the trigger pin (little pin above plastic trigger that puts pressure on the trigger mechanism itself inside the gun) could be a little bent. If you or someone else has ever reassembled your gun with the pin in the "up" position, it could have been forced and gotten a bit bent.

@@AlexanderGaos thank you. I will try and let you know.

Hey Alexander, I managed to disassemble the gun. I made a big mistake while doing it. I released the pressure while having the power switch in the low position (up) so only a small portion of the air was released. Then I removed the trigger, saw the pin underneath and decided to press on it. The rest of the air blew into my face and the pin flew away lol I am glad I didn't lose an eye and I was lucky to find the pin. I don't remember if I switched the power to the high position before or not. You were right, the metal horizontal trigger that releases the piston inside the barrel is a little bit rusty, the o-rings look good, the gun is only 2 years old. I will try to use some wd40 on it and clean the barrel of rust debris. In the other video you explained how to pour fork oil with a pump. Can't find it, will order from Amazon. Where should it go? Inside the outer chamber or inside the barrel or both and how much oil approximately? Thanks again for your help!

@Alexander Gaos - NOAA Federal Forgot to ask. Would a silicone spray like Blaster work to lubricate and protect from moisture and corrosion?

@@доброум That's crazy! I'm glad you didn't get hurt...and what luck to find the pin, that could have been a major game spoiler! Really clean the pin and firing mechanism well...if you have a soft metal brush, that could be good, but maybe that's overkill? Anyway, lube all the parts with the fork oil as you assemble...it's messy, but better to have everything well lubed. Once the gun is assembled, stick the pump into the fork oil container and suck up a bunch of the oil, then attach the pump to the gun (same as if you were going to pump it up) and push the pump down, inserting the oil into the gun. Get it? Do that a few times and you should be good to go....then you'll just have to pump up the gun. It will take like 600 pumps, but just take your time ;)

Hey Dom, they're standard across Mares...so just go to ebay and google "Mares pneumatic pump" and you should see plenty. They're typically like $25-$30. These are hand pumps.

@@AlexanderGaos hi yes that's 25 to 30 works out to about R500 bucks

Yeah I wonder too…..thanks RU-vid 😢

hi, I have the same exact problem. did you solve it and could you give me some advice?

@@federicocorrente4286 nope, i just left it and bought a new speargun. I suppose you should somehow block the air valve bolt thread from spinning. I'm not sure how though. Maybe someone has an idea?

@@federicocorrente4286 maybe some kind of reverse-thread bolt could be used to fix the bottom part.

Sorry for the super delayed response Willis! Here are the details: Maxima 55901 10WT Standard Hydraulic Fork Oil - 1 Liter Bottle

delayed? that was the fastest response I've had. thanks, I'll check that out. on you, plus one! Keep cranikin'
