How to start a Stihl Chainsaw that won't start?
If your Stihl Chainsaw engine doesn't start, it might be due to insufficient fuel. To resolve this, mix fuel and refuel the chainsaw. Alternatively, the engine could be flooded; in this case, clear the combustion chamber. The carburetor may also be too hot, so allow the chainsaw to cool down. If the carburetor is iced up, allow the saw to warm up to +10°C.
What to do if Stihl MS 400 C-M chain does not rotate?
If the Stihl Chainsaw chain does not rotate when the throttle is opened, it could be due to several reasons. First, check if the chain brake is engaged and, if so, disengage it. Another possible cause is that the chain is over-tensioned; in this case, tension the chain properly. Finally, the bar nose sprocket might be blocked. Clean the bar nose sprocket with STIHL resin solvent.
Why does my Stihl Chainsaw smoke while cutting?
If you notice smoke or a burning smell while cutting with your Stihl Chainsaw, it could be due to a chain that is not properly sharpened, so you should sharpen the chain properly. Another possible cause is insufficient chain oil in the tank; in this case, fill up with chain oil.
Why is my Stihl Chainsaw acceleration poor?
If your Stihl Chainsaw experiences poor acceleration, it could be due to an over-tensioned chain. Make sure to tension the chain properly. Additionally, the chain lubrication system might not be supplying enough oil. Increase the oil feed rate to resolve this.
Why Stihl MS 400 C-M engine does not reach maximum RPM?
If the engine of your Stihl Chainsaw does not reach maximum RPM, it might be because the saw is not correctly tuned to ambient conditions. Calibrate the saw to resolve this issue.
