Top plate cutting angle Depth gauge 20BPX :55° 33SL, 95VP :60° • Place the depth gauge tool firmly on guide bar so that depth gauge protrudes. Then file top of depth gauge with the flat file until flat with top of the depth gauge tool. -Be sure to round off the front edge of the depth gauge. Properly filed cutters are shown in illustration. When setting of the chain is finished, soak it in oil and wash away filings completely before using. -When chain has been filed on the bar, supply sufficient oil to it, rotate the chain slowly to wash away the filings before using again. -If the chain saw is operated with filings clogged in the groove, the saw chain and the guide bar will be damaged prematurely. -If the saw chain becomes soiled with resin, for instance, clean it with kerosene and soak in it oil. NOTE These angles are referred to as Oregon 20BPX, 33SL, or 95VP. To sharpen other follow chain manufacturer’s instruction. 30 TROUBLESHOOTING EnginE PrOBLEM TrOUBLESHOOTing CHarT Problem Check Status Cause remedy Engine cranks starts hard/ t'doesn start Fuel at carburetor No fuel at carburetor Fuel strainer clogged Fuel ilne clogged Carburetor Clean or replace Clean or replace See your Echo dealer Fuel at cyilnder No fuel at cyilnder Carburetor See your Echo dealer Muffler wet with fuel Fuel Mixture too rich Open choke Clean/replace air filter Adjust carburetor See your Echo dealer Spark at end of plug wire No spark Stop switch off Electrical problem Interlock switch Turn switch to ON See your Echo dealer See your Echo dealer Spark at plug No spark Spark gap incorrect Covered with carbon Fouled with fuel Plug defective Adjust to .65mm (0.026 in.) ...
