Hello All,

I hope I am not asking obvious question(s)...I tried to do a search on previous posts...but couldn't find the search feature.

I have had a Diana (RWS) Model 36 for quite a while, and have not done any periodic maintenance on it. I probably have only shot 200-300 rounds thru it in the time I have owned it. I bought it used.

My questions are:

1. What sort of periodic & long term maintenance do I need to do to it...and as far as the periodic stuff...where do I oil it to keep the seals from going bad, and operating smoothly?

2. Did this rifle come with a users manual when new, since I bought it used, I didn't get a manual with it. Is there somewhere online I can get a copy of the manual?

Thanks,

- Nick

Airguns require less maintenance then powder burners. Don't worry about cleaning after the inital clean until 500-1000 rounds. If it doesn't affect the accuracy of the rifle.

Thanks for your reply.

I am not so concerned about cleaning...I am more concerned about specific areas of the Diana 36 that need to be oiled periodically to keep it operating well.

Specifically...are there a spot or spots that need to be oiled periodically...such as the rubber seal(s) or the main spring?

Thanks,

be the same as any other break barrel springer. Keep all the pivot points on the barrel and cocking linkage oiled, and the mainspring should be lightly oiled occasionally (every 1000 - 2000 shots). You should have to remove the stock for this. From what I understand, unless you've got an old gun with leather seals, there's no need to put any oil in the compression chamber, but if you do, be sure its high flash point oil designed for compression chambers.

and you can get parts diagrams and lists from Chambersgunmakers.co.uk

RLM,

Hey thanks a ton for that info! I was at Airguns of Arizona before..but didn't realize they had manuals (that list on the left is kind of long).

I looked over the manual for maintenance instructions...but found it rather lacking...it didn't even mention anything regarding oiling of the rubber seal, or lubrication of the mainspring...and no assembly/disassembly instructions.

I guess the rubber seal just gets replaced when it dries out or dry rots (but I haven't seen these for sale anywhere). And I guess the owner is supposed to have a "crystal ball" on how to lubricate the mainspring...unless it is complicated, and needs to be done by a pro (which doesn't seem necessary).

Thanks again for the info,

on the maintenance info. I guess for liability reasons they want to make it as difficult as possible for the owner to know what to do and how to do it, so that you'll return it to them for maintenance. My RWS48 manual was pretty lacking, but did at least give a maintenance shcedule of sorts, though didn't tell you how to access the spring, etc. It actually does tell you to put 1-2 drops of chamber oil down the transfer port every 1000-2000 shots, but I've been advised by several folks that its not really neccesary. I had the same question about the spring and was told to remove the stock and oil lightly through the cocking slot. I have yet to do it though, everything seems to be working smoothly and I figure I'll wait for signs that it needs maintenance, change in sound or feel during cocking or firing or loss of velocity.

RLM or anybody,

On my Diana Model 36 (break barrel)...is the rubber O-ring that seals the air in the barrel when the spring let's loose...is it located right where you place the pellet's?

Also...how often should it be lubricated?

Thanks,

been given or read. O-rings are cheap, better to replace one every couple thousand rounds if needed than to get too much oil in the works. I would guess that if you feel you need to keep the O-ring oiled to keep it from deteriorating, you should use some kind of chamber lube (RWS makes some). Because chamber lube is designed to withstand high temperatures, which the O-ring is briefly subjected to every time you fire the gun, it should be safe, but oil sparingly and wipe off excess, you don't want a bunch of oil in the O-ring groove to detonate when you fire, its hard on the gun. I would suspect every 500-1000 rounds would be sufficient.
