Golden Rules of Chainsaw Milling

Top tips and ways to get the most out of chainsaw milling

• Keep the chain sharp most people require some form of guide to get the chain perfect tooth length the same, angle the same, depth gauges consistent. Nearly all issues we come across always come down to the chain – you can get away with all sorts of mistakes when cross cutting timber – not so with milling. The best tool on the market is still the Granberg Precision Grinder click here – use with our long lasting diamond grinding stones click here.
• Wedge the cut so it does not trap the bar don’t wedge to high but keep the cut open so the saw can cut without the chain getting trapped.
• Get you first cut straight because if you don’t you will have issues all the way through the log! If the top cut is not flat put your first cut rails back on the log and re saw a board so that the log is now flat. Our Panther first cut rails are designed to do just this click here.
• Rest the saw down the log – particularly in hot conditions let the saw idle for 30 seconds every 1m you cut. This allows the saw to get rid of some of the heat build up.
• At the end of the log do not switch saw straight off. Remove from log gently rev and allow chain to remove any sawdust trapped in the bar. Allow saw to idle 1 minute before you start cutting again or before you turn off.
• Do not run your saw out of fuel – always make sure there is fuel in the tank – if you keep allowing the saw to run out of fuel completely you will have idling and other issues later in the saw’s life.
• Do not force the mill to cut it should cut without undue pressure so if it is not cutting then pull it out the log and assess the reasons.
