CHAIN SHARPENING WARNING: Improper chain sharp- ening techniques and/or depth gauge maintenance will increase the chance of kickback which can result in serious injury. WARNING: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving. Conditions which indicate the need for chain sharpening: S Reduction in size of wood chips. The size of the wood chip will decrease as the chain gets duller until it becomes more like a powder than a chip. Note that dead or rotted wood will not produce a good chip. S Saw cuts to one side or at an angle. S Saw has to be forced through the cut. Tools required: S 5/32 inch (4 mm) diameter round file and file holder S Flat file S Depth gauge tool TO SHARPEN CHAIN: 1. Move ON/STOP switch to the STOP position. 2. Check chain for proper tension. Adjust chain tension if necessary. See CHAIN TENSION section. 3. Sharpen cutters. S To sharpen the cutters, position the file holder level (90˚) so that it rests on the top edges of the cutter and depth gauge. NOTE: The chain has both left and right hand cutters. 16
