Savage .22 model 3 D

[astroguy]

i've purchased a used .22 Savage Model 3C single shot for my son and it works ok. The only issue is that the lever or handle of the bolt is loose and it tends to twist a tiny amount as you rack the bolt back and this wee bit of twist causes the handle of the bolt to bind in the drawback channel.
The is little info that I can find on the net about this gun or how to actually remove this loose bolt lever/handle? or how do I tighten this up?n
