MAINTENANCE
CHAIN MAINTENANCE (See Figure 21)
For smooth and fast cutting, the chain needs to be maintained properly. The following conditions
indicate that the chain requires sharpening:
• Wood chips are small and powdery
• Chain must be forced through the wood during cutting
• Chain cuts to one side
During maintenance of the chain, consider the following:
• Improper filing angle of the side plate can increase the 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 and stones, or have been abraded by mud or
sand on the wood, have service dealer sharpen chain.
