20 Most Recent Hitachi CS33EB16 16" Rear Handle Chain Saw Questions & Answers


The oil pipe is poorly fitted to the oil pump and allows bar/chain oil to sneak past the seal. Buying a new oil pipe may not fix the issue since this is common on brand-new saws. Warranty work probably won't help you.

How I fixed my saw: I bought two small O-rings about the diameter of the oil pump and fitted them to act as hose clamps around the oil pipe. See attached picture. It worked perfectly and now my saw runs out of fuel before oil. Sears/Craftsman have a great video on how to remove the clutch assembly.

There are many possibilities. contaminated fuel, wrong fuel oil mixture. air leak in fuel line, carburetor contaminated, or needs adjustment, choke problems, throttle problems. Try a small engine mechanic.

No, and it's a potential fire/explosion hazard! You have probably lost the fiber or plastic liner that prevents this; it's a small disk that fits inside of the fuel cap. Purchase a new fuel cap for your machine ASAP!
