25In order to prevent carburetor icing in conditions of low temper-ature combined with high humidity, and in order to get up tooperating temperature faster in subfreezing temperatures,heated air can be taken from the cylinder.At temperatures above freezing the carburetor must NOT befed heated air.Failure to follow these instructions can lead to damageto the cylinder and piston!Working in winter- Remove the filter cover and air filter (see "Cleaning the airfilter").- To enable hot-air induction from the cylinder, remove theplug (A/1) using the universal wrench.NOTE:Keep the plug in the saw’s tool kit. You must put the plug backin at temperatures above 0° C / 32° F.- Reinstall the air filter and filter cover.The chain needs sharpening when:- The sawdust produced when sawing damp wood looks likewood flour.- The chain penetrates the wood only under great pressure.- The cutting edge is visibly damaged.- The saw is pulled to the left or right when sawing. This iscaused by uneven sharpening of the chain.Important: Sharpen frequently, but without removing toomuch metal!Generally, 2 or 3 strokes of the file will be enough.Have the chain resharpened at a service center when youhave already sharpened it yourself several times.DProper sharpening:CAUTION:Use only chains and guide bars designed for this saw(see the Extract from the spare-parts list)!- All cutters must be of the same length (dimension a).Cutters with different lengths result in rough running of thechain and can cause cracks in the chain.- Minimum cutter length: 0.11" (3 mm). Do not resharpen thechain when the minimum cutter length has been reached;at this point, the chain must be replaced (see the Extractfrom the spare-parts list and "Replacing the saw chain").- The depth of the cut is determined by the difference inheight between the depth limiter (round nose) and thecutting edge.- The best results are obtained with a depth-limiter depth of.025" (chain: 085 / .325") or .030" (chain: 094, 102 / 3/8").CAUTION:Excessive depth increasesthe risk of kickback!MAINTENANCESharpening the saw chainCAUTION:Before doing any work on the guide bar or chain, alwaysswitch off the engine and pull the plug cap off the sparkplug (see "Replacing the spark plug"). Always wear pro-tective gloves!C
