• Wood chips are small and powdery.
• Chain must be forced through the wood during cutting.
• Chain cuts to one side.

•
risk of a severe kickback.
• Depth gauge (or raker clearance) setting determines
the height the cutter enters the wood and the size of
the wood chip that is removed. Too much clearance
increases the potential for kickback. Too little
clearance decreases the size of the wood chip thus
decreasing the chain’s cutting ability.
• If cutter teeth have hit hard objects such as nails or
stones, or have been abraded by mud or sand on the
wood, have service dealer sharpen chain.
