Felling trees at the farm today, when the chain suddenly became very "grabby". Saw is a new Echo CS400 that has about ten hours of flawless use to this point. (Saw had a new chain at the start of the day, hand filed after second tank of gas.)
I had filled gas tank and bar oil tank about 10 minutes before problem. Troubleshooting after problem: Checked tension - good. Re-checked bar oil - good. Removed sprocket guard and found a small amount of oily sawdust residue - normal. (Cleaned out debris.) Examined the chain for broken teeth, did not observe any.
Went back in the cut and was still "grabby". So bad, that chain felt dry to me. Tried chain lubrication test - no oil at half throttle or full throttle.
I removed the sprocket guard again, but could not see any problems.
Can any of the experts give me some advice? I think the oiler is the problem, but it could be something else.
(Chainsaw experience level is around "seasoned homeowner". I am moderately mechanical, but have never disassembled a chainsaw.)
I will get into the saw tomorrow on the work bench. Plan is to check the oil adjustment screw to see if it is still functioning normally. If I remove the inner guide plate will I be able to see the oiler ports?
Anything else I should work on while the saw is on the bench? Anything I definitely should not work on because a newbie could screw it up?
Finally, there is a small black hose that is hanging free (at one end) in the little gap between the rear handle and the body of the saw. I observed this when I was examining the saw in the field. (I believe it is a vent assembly.) I don't know if this is a "broken" part that should be attached at both ends, or if I had never observed it before.
Thanks,
Rod
