That's really going to come down to the reason it's jammed. Could be as simple as just working the mechanism, it could be a matter of cleaning and lubricating the mechanism, or it could need replacement parts.
with a hammer or a rock
Pry it off with a flathead screwdriver.
well in that problem what u have to do is use flat screwdriver to slowly pry off the cocking mechanism and wiggle it every once in a while. then it should come out but if it doesn't work then I don't know how to help you. HOPE THIS REALLY HELPS!
According to the manufacturer the dahle shredder is easy to use and unjam when blocked. It can be necessary to use WD40 to keep the parts lubricated. You can purchase a shredder performance kit to help you keep the mechanism working properly.
use an unjamming rod to unjam it if there are bbs inside of it. When cocking, only do it once and make sure that it is all the way forward/down. I used to have a utg l96 and it had the same problem
Ive also been looking for a mechanism for the ranger but cant find it i have seen 1 drawing but was useless
All you have to do is put in front and rear bolt, Put in the coking pin, the put in the rear spring and cap.
"cocking" translates to, "armamento" in Italian.
This all depends on the model. I suggest you go online and do a search for "air gun repair" and locate a place to repair it for you.
pry off the cocking bolt with a flathead screwdriver by placing the flathead screwdriver in between the knob and the gun and pushing the screw driver against the knob as if you are trying to push it away from the gun.. the knob came unstuck for me! Thanks to this answer!
on top of the gun is a little slide panel which should hep unjam -j.p
it's impossible
