FWB 602 - Two rifles, two problems
Posted: Sat Jul 16, 2016 8:35 pm
By coincidence I have two different problems to report and ask for help with, on two different guns. Tonight a friend and I had planned on shooting my FWB 602 for a little friendly match and there was a problem and we weren't able to shoot it. I arrived home with the intention of coming here to ask for help and in my email was a message from the president of our local rifle club telling me about a problem with the club's 602 and asking me (since I also own one) if I might be able to come here and try getting some advice. So, two rifles, two different problems. SIGH
FWB #1 (Mine): Bought it used two months ago and was assured (by a reputable and experienced dealer) that all the seals were in perfect condition. I've shot about 3,000 pellets through it without issue. Last night during some shooting it sounded like a couple of shots were under-powered but that was only about two shots out of 60 and the problem didn't seem to be serious. Well, tonight we weren't even able to get one shot out successfully. The gun goes pffft, and the pellet falls far shot of the target. Shooting without a pellet the sound is just about normal... perhaps a little less strong. Put a pellet in and shoot, and it just goes pffft and the pellet falls to the floor. Nothing sounds or feels unusual during the cocking/loading process. I have no idea what to check or really even how this gun works internally. And I don't have a manual with the gun.
FWB #2 (the club's gun): Here's what I understand... There's a report from an experienced member that the 602 has an odd sound after it has been shot and is re-loaded. The president looked at it and it seems that once the shot is fired, and upon going through the motion of loading the next round there is a distinct pop when the crank-lever is moved, It sounds like there is still residual air pressure after the shot and it escapes at the moment the loading lever is moved. The same puff sound also occurs when the dry-fire lever is pushed forward to reset the trigger and as soon as the trigger is pulled, that residual air passes through to the barrel.( at a much lower pressure).
This second gun/problem sounds very much like the one being reported here with a model 601 FWB, which doesn't seem to have been resolved yet.
Any chance that there's a technical manual for these guns to be found somewhere? Any ideas about either of these problems and their solutions?
Thanks very much for any help.
