See "Accessories" for the order number. Correct even the smallest excess height with a special flat file (1). See "Accessories" for the order number. Round off the front of the depth limiter (2). D C The sharpening angle of 25° must be identical for all cutters! Different angles result in a roughly, irregularly running chain, increase wear and tear and cause chain beakage. The front rake 60° of the cutter results from the cut depth of the round file. If the proper file is used in the right manner, the correct front rake will be obtained automatically. 25° 29 8 11 10 7 5 4 5 1 6 7 2 3 Cleaning the brake band and sprocket interior CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see "Replacing the spark plug"). Always wear protective gloves! CAUTION: Start the chain saw only after having assembled it completely and inspected. Remove the sprocket guard (1) (See "PUTTING INTO OPERATION" figs. B) and clean the interior with a brush Remove the chain (3) and guide bar (2). Unscrew screw (4) and remove the guide plate (5). Unscrew screw (6) and remove the brake mechanism cover (7). A SERVICE B Clean the guide plate (5) and brake mechanism cover (7). Use a brush to clean the interior, especially the brake mechanism (11). Make sure to leave no residue in the oil guide groove (10) NOTE: The brake mechanism cover (7) holds the lever (8) in place. Before putting the cover back on, check the lever for proper positioning. First put on the brake mechanism cover (7) and then the guide plate (5). For replacing the guide bar, chain, and sprocket see "PUTTING INTO OPERATION A-H". After assembly, always check the functioning of the chain brake (see “Checking the chain brake”) NOTE: The chain brake is a very important safety device and like any other component subject to normal wear and tear. Regular inspection and maintenance are important for your own safety and must be done by a DOLMAR service center. 12 16 15 1413 17 Replacing the saw chain CAUTION: Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)! Check the sprocket before mounting a new chain. Worn out sprockets (12) may damage the new chain and must therefore be replaced. Remove the sprocket guard (1) (See "PUTTING INTO OPERATION" figs. B). Remove the chain and guide bar. Remove circlip (13). CAREFUL: The circlip will jump out of the groove unless you hold it down with your thumb while removing it. Remove thrust washers (14 and 15). Replace the old sprocket (12) with a new one (16). For the part number consult the “Extract from the spare parts list”. Assemble the new sprocket, thrust washers and circlip. For replacing the guide bar, chain, and sprocket see "PUTTING INTO OPERATION A-H". NOTE: New chains stretch, so check the chain tension frequently (see “Checking the chain tension”). D C ReplacingthefuelfilterThe felt filter (17) can become clogged. It is recommended to replace the fuel filter once every three months in order to ensure unimpeded fuel flow to the carburetor. To remove the fuel filter for replacement, pull it out through the tank filler neck using a piece of wire. Bent wire at one end to form a hook. E Cleaning the guide bar CAUTION: Protective gloves must be worn. Regularly inspect the bearing surfaces of the guide bar for damage, and clean them with a suitable tool. 31 3 5 4 A Cleaning the air filter CAUTION: To prevent eye injury, always wear eye protection when cleaning the filter with compressed air! Do not use fuel to clean the air filter. Unhook the filter hood clips (1) with the combination tool and remove the filter hood (2). Pull out the choke (3) to prevent dirt particles from getting into the carburetor. Unhook the air filter retainer (4) by pressing in the direction shown by the arrow. Pull the air filter (5) up and out. IMPORTANT: Cover the intake opening with a clean cloth to prevent dirt particles from getting into the carburetor. Choosing the right filter: The fleece filter is for use in dry or dusty conditions. The nylon filter is for use in damp conditions. Pry apart the top and bottom of the air filter as shown in Figure. Cleaning the fleece filter: Carefully tap out dust or carefully blow out dust from the inside with compressed air. Do not brush the fleece, as this will force dirt particles into the fabric. If the filter is very dirty, it can be washed in lukewarm water with regular dishwashing detergent. Note that the fleece filter does not need to be cleaned until there is a noticeable loss of power. If cleaning the filter does not bring an improvement in performance, it is time to replace it. Cleaning the nylon filter, the nylon filter in the filter hood and pre-filter: Use a soft brush or blow out dirt from the inside with compressed air. If the filter is very dirty, it can be washed in lukewarm water with regular dishwashing detergent. Clean frequently (several times a day) when working in very dusty or d...
