What condition is the rifle in? Many were imported & sold that were brand new. I have one but it so long since I shot it I do not remember how it was. However your problem is probably not the ejector but rather the extractors. They may be holding the cartridge so tight it takes a hard 'slam' to eject the case. This condition could last till the rifle got some serious use! Working the bolt briskly (not 'slamming') will not hurt anything! The left extractor is really just a spring to hold cartridge in place against the bolt face, the right is the hook which pulls it out. The left side of case must hit ejector hard enough to throw case out to the right, not hard enough and it just drops down.
You can never go home again.
