AIR FILTER CAUTION: Do not clean filter in gasoline or other flammable solvent to avoid creating a fire hazard or producing harmful evaporative emissions. 13 Cleaning the air filter: A dirty air filter decreases engine performance and increases fuel consumption and harmful emissions. Always clean after 10 tanks of fuel or 5 hours of operation, whichever comes first. Clean more frequently in dusty conditions. A used aire filter can never be completely cleaned. It is advisable to replace your air filter with a new one after every 50 hours of operation, or annually, whichever comes first. 1. Loosen 3 screws on cylinder cover. 2. Remove cylinder cover. 3. Remove air filter. 4. Clean the air filter using hot soapy water. Rinse with clean cool water. Air dry completely before reinstalling. 5. Lightly oil air filter before installing to improve the efficiency of air filter. Use 2- --cycle engine oil or motor oil (SAE 30). Squeeze excess oil from filter. 6. Reinstall air filter. 7. Reinstall cylinder cover and 3 screws. TIghten securely. AirFilterCylinderCoverScrewsCylinderCover INSPECT MUFFLER AND SPARK ARRESTING SCREEN As the unit is used, carbon deposits build up on the muffler and spark arresting screen, and must be removed to avoid creating a fire hazard or affecting engine performance. Replace the spark arresting screen if breaks occur. Muffler Diffuser Spark Arresting Screen Muffler Cover Screws Muffler Muffler Body Cover Cleaning is required every 25 hours of operation or annually, whichever comes first. 1. Loosen and remove the 2 muffler cover screws. 2. Remove the muffler cover (cover snaps off muffler body). 3. Remove muffler diffuser and spark arresting screen assembly. Notice the orientation of these parts for reassembling. 4. Clean the spark arrestor screen with a wire brush. Replace screen if breaks are found. 5. Replace any broken or cracked muffler parts. 6.

CARBURETOR ADJUSTMENT WARNING: The chain will be moving during most of this procedure. Wear your protective equipment and observe all safety precautions. The chain must not move at idle speed. The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions: S Chain moves at idle.See IDLESPEED- --T adjusting procedure. S Sawwillnotidle.SeeIDLESPEED- --T adjusting procedure. Idle Speed- --T Allow engine to idle. If the chain moves, idle is too fast. If the engine stalls, idle is too slow. Adjust speed until engine runs without chain movement (idle too fast) or stalling (idle too slow). The idle speed screw is located in the area above the primer bulb and is labeled T. S Turn idle speed screw (T) clockwise to in crease engine speed. S Turn idle speed screw (T) counterclock wise to decrease engine speed. If you require further assistance or are unsure about performing this procedure, contact your authorized service dealer or call 1- --800- --554- --6723. BAR MAINTENANCE If your saw cuts to one side, has to be forced through the cut, or been run with an improper amount of bar lubrication it may be necessary to service your bar. A worn bar will damage your chain and make cutting difficult. After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole. To maintain guide bar: S Move ON/STOP switch to the STOP position. S Loosen and remove chain brake nuts and chain brake. Remove bar and chain from saw. S Clean the oil holes and bar groove after each 5 hours of operation. RemoveSawdustFromGuideBarGrooveOilHoles SBurringofguidebarrailsisanormalprocessofrailwear.Removetheseburrswithaflatfile.
