It is upsetting you have this concern.
Did you purchase the unit new? If so you can go to your local authorized Husqvarna dealer with your original dated sales receipt and the dealer should be able to install the missing parts and file a warranty. Since the 150 series is a couple years old now if you purchased this used, then you can purchase the parts from you local authorized Husqvarna service center, I fell sure these are not expensive parts.
