Maintenance

There is not much maintenance with these air rifles at least not with mine. Clean the barrel once the point of impact shifts. I keep clean in general. Remove any water asap Light lubrication. Change o rings when they wear out. I wouldn't store the gun with any springs compressed. Read your manual to double check what needs to be done also.

Lubing pellets you can try it. If it improves anything then keep doing it. Most do not lube. 

Im sure there will be others along to help out as well.
