The hangey downey pointy thing is the cantiliver, which, in this case, should be aluminium. At the end of it, pointing down towards the record, you should be able to see, with the help of a magnifying lense, a tiny diamond tip, aka
"The stylus".
If there´s no stylus, you gotta get a replacement.
You must unscrew the headshell by turnig the round screw head at the top of the headshell / arm joint. Then gently pull the headshell away, while holding the tonearm tube with your other hand, in order to avoid damaging the arm´s bearings.
You should now be able to properly inspect the red cantiliver plastic support and check for the stylus.
Then check
these guys for a replacement.
Assuming the cartridge is properly aligned, you should just check the VTF ( Vertical Tracking Force ), which I´d guess to be around the 1.5 / 2.0 grams, and the antiskating force to a similar value.
Make sure to keep your TT levelled.
Under no circumstances you should play dirty records.
Have fun.
