Cleaning IZH 46-M out of the box - Izzy newbie

My daughter just got this from her grandparents to replace a club Daisy 747. Nice pistol. I searched previous posts and found the question but not a real good answer.

When removing the factory preservative, how much disassembly is necessary? Removing the piston, removing the compression cylinder, any back end disassembly necessary? I have oil specifically for air compressor components, is that adequate for oiling when necessary or is Pellgunoil more appropriate?

Can't wait to shoot this myself.

Thanks

Just clean the bore and get started. I pull a wet patch (TSI301) through after every tin (probably overkill), and lube the pivot points and a drop in the chamber annually.

I think I just wiped all of the exposed surfaces off; there wasn't that much preservative on mine when I got it.

if I'm not mistaken, pellgun oil is used for spring piston air guns which have much higher peak chamber pressure than a single stroke pneumatic like the Izzy. Ordinary oil can diesel in the SP guns. Any good light/medium oil will be fine for the joints. I use Break Free CLP for pretty much anything like that. Just be sparing with it. I hope your daughter has fun with the Izzy - it is a pretty impressive shooter.

Ordinary oil will also diesel in SSPs (don't ask), but on the compression stroke.

I've had a container of Beeman Chamber Oil that I've used for many years on FWB90, Pardini K58, and FWB 100 with no problems.

With apologies to the OP for hijacking his thread ...

Sorry, Rover, but I gotta ask -

Oil diesels when compressed and heated. According to some old Beeman catalog I have around here somewhere, the piston comes to the end (or nearly) of the chamber before the pellet stars to move which means that the entire gas volume of the cylinder is reduced by orders of magnitude in a tiny fraction of a second. I have made fire-starters that use a 1/4" dia x 2" long piston in a plastic chamber that will ignite bits of fluff, but you really have to slam the piston quickly to generate a sufficient pulse of heat. I can't see how you can stroke an SSP fast enough to generate heat much more quickly than it can dissipate, so how did you manage to ignite the chamber oil? What oil was involved anyway?

Inquiring minds want to know!

It is no trouble at all (as opposed to what some here claim) to very quickly and easily charge a SSP. That's all it takes if your oil (or other cleaner) gets into the compression chamber. If I recall correctly, I was using a solvent to clean the bore.

On my K58, it instantly bent my charging lever into a U shape. Fortunately, Don Nygord had no trouble repairing the gun.

Ok, that 'splains it. A solvent would have higher volatility and lower flash point than a lubricating oil - it would diesel much more easily.

And I started shooting with an Izzy, so I also have little sympathy for most shooters who complain about cocking effort. It is more effort than the point-and-click of a PCP gun but not enough to make a difference. The only thing that makes a big difference in scores is practice.

We now return you to our regularly scheduled programming ...

Pellgun oil will be fine - if that's what you have, go with it.
