The only way to avoid kickback is to make sure that the kick- back zone of the bar never touches anything.
Page 12 2 Sharpening your chain and adjusting raker clearance The risk of kickback is increased with a badly sharpened chain! When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small.
To maintain cutting performance you must file back the raker teeth to the recommended height. Aim the tip of the saw at a light coloured surface about 20 cm away. Remove these with a file if necessary. Replace the bar if necessary. Page General Rules General rules If you understand what kickback is and how it happens then you can reduce or eliminate the element of surprise.
