Thanks for the reply, but not sure I fully understand.
The user manual pg 16 says:
Needle bearing lubrication
Both versions of sprockets have a needle bearing on the
drive shaft, which has to be greased regularly (once a
week). CAUTION! Use only high quality bearing grease or
engine oil.
Does this mean I have to bring the saw to a service center every week? Seems like the manual is referring to something that can and should be done regularly by the user, not by a professional mechanic. Thanks.
