If you have to do maintenance tasks on your Linhai 80 PY then it is always recommended to have a Workshop Manual to use as personal reference in the event that you need to know tips to strip off a particular component for instance the Brake Discs and match it again properly.
Linhai 80 PY Workshop Manuals are able to offer certain diagnostic facts for the car or truck therefore if something is not working it can help you identify what the problem is and the way to correct it. You will be able to assess if you can do this yourself or that the job is just too big you can make a booking for your 80 PY into a decent garage.
