Question about Husqvarna 450 e-series 18" Chain Saw

1 Answer

Hi, I go t a new Husqvarna 450. It cut fine for 10 mins and then stopped cutting well. Engine runs fine but it barely cuts at all. The cut is black as if burned and there's sparks from the chain on the bar. The edge of the bar is blackened even though the oil is working ok. please help.

    hi, take your saw to a local dealer and have the chain checked and sharpened , try and get them to show you the proper way to tension and sharpen your chain ( you will need a file and guide properly setup for the type of chain your using ) you may also need to file off the high spots on your chain bar or replace it if the bar is badly scorched or bent . remember a chainsaw requires daily maintenance ( 2 stoke mix, clean air filter, chain oil filled up , chain sharp and properly tensioned ) hope this helps. p.s try not to cut into soil :)

    Thanks for your help. The problem has been solved. The chain must have hit a pocket of dirt which blunted it and pulled dirt into the oil groove on the bar.

Suspect that the chain hit a rock or pocket of dirt which will dull the chain in a heartbeat plus pull debris into the chain groove area. Remove the bar and chain and clean everything thoroughly including the chain and bar groove. Inspect the chain teeth carefully looking for burned teeth and other physical damage. If badly damaged, suggest replacing the chain. It's not likely that the bar sliding surfaces have been severely damaged. When you have everything back together and the chain adjusted, start the saw and run the bar tip near some cardboard--it should throw off a thin line of oil in a few moments. There should be an oil volume adjustment screw on the back or just under the same area near the chain return. Turn the screw CCW to increase flow. Hope this helps!

I have a 450, and I would like to increase my bar oil output. Where is the adjustment screw? Please!


There is no adjuster for the Husqvarna 450. Husqvarna recommend that if there's not enough oil reaching the bar that you slow down the engine by adjusting the carburettor screw. I have the same saw and also wanted to adjust the oil flow. I didn't change the carburettor and it's still cutting away without doing any damage. It's meant to use less than a tank full of oil to the tank full of fuel when you're cutting near constantly. With stops in between it will use more fuel and less oil.
