Taking apart the saw a bit to install the module, I was reminded how impressive it is that the saw stays pretty clean inside. Obviously, most all chainsaws get loaded up with oily sawdust over time, sometimes it seems like they weigh an extra pound from all the gunk. With the 394, I have literally never cleaned the air cleaner- I've tried a few times but there was nothing to clean from it. The whole area holding the carb and air cleaner is clean. Even the side cover for the bar and chain stays basically clean- nothing to scrape or clean out. Seems like a well engineered saw that stays pretty free of debris in addition to cutting well.
Ha, look at me- ready to junk the saw 3 weeks ago, now raving about it's character...
