Dolmar Chainsaw Guide

Hello guys,

I bought my Dolmar PS-421 around 2 years ago and the engine has been deteriorating for a while, now it’s very difficult to get it to start at all. What could be causing this issue?

Hi Melvin,

I think it’s almost certainly a problem with the air filter being clogged. Remember that filters need to be changed based on your location’s conditions, so if the air there is more dusty than usual you will need to change the filter more often to maintain optimum performance
