10 10 RECOMMENDATIONS FOR PREPARING FUEL MIXTURE To prepare the fuel mixture, use unleaded gasoline with an octane rating of 92 and motor oil for two-stroke engines with air cooling in a ratio of 50: 1. Champion engine oil is recommended for two-stroke air-cooled engines that are classified by API TC-3 or JASO FD, or similar oils from other manufacturers. Preparing THE FUEL MIXTURE To prepare and store the fuel mixture, use a special container for gasoline. Do not use containers made of food-grade plastic. It is forbidden to prepare the fuel mixture directly in the fuel tank. For the preparation of the fuel mixture it is forbidden to use oil intended for water-cooled engines, oil for two-stroke engines with low maximum revolutions, oil for four-stroke engines. To determine the mixing proportions, use the table in Fig. 5 Gasoline Oil Ratio 1 liter 20 ml 50: 1 5 liters 100 ml 50: 1 10 liters 200 ml 50: 1 Fig. 5 Do all work with fuel only outdoors, or in good ventilated area, away from sources of ignition. Do not start the engine if fuel is spilled. Wipe the fuel tank off any spills with a dry, clean cloth or wait for it to dry completely. 1. Pour half of the gasoline prepared for operation into the container. 2. Add the required amount of recommended engine oil. 3. Close the container lid tightly. 4. Shake the fuel mixture thoroughly in a container. 5. Slowly open the lid of the container to let out air, then add the remaining gasoline. 6. Close the container and shake well again. Shake the mixture thoroughly in a container before each filling.
11 11 FILLING THE FUEL TANK 1. Before refueling the fuel tank, stop the engine and allow it to cool completely. 2. Fill the fuel tank outdoors, or in a well-ventilated area, away from sources of ignition. 3. Clean the debris near the fuel tank cap. 4. Slowly unscrew a cover of a fuel tank. 5. Carefully fill the fuel mixture. 6. Do not completely fill the fuel tank; there should be room for expansion of the fuel. 7. Screw in the fuel cap securely with your hands. Before starting, wipe the fuel tank dry from the remnants of spilled fuel. The ready-to-use fuel mixture is recommended for use within 90 days. During prolonged storage, the fuel mixture oxidizes, becomes heterogeneous and unsuitable for use. To prepare the fuel mixture, use fresh, high-quality gasoline. Carefully maintain gasoline / oil ratio. Never add clean gas to refuel your chainsaw. Engine failure as a result of using fuel quality that is not acceptable by state standards, working on clean gasoline, working on old fuel mixture or on a mixture with the wrong gasoline / oil ratio, the use of non-recommended or low-quality oil, cannot be repaired under warranty.
12 12 OPERATION Do not run in or leave the engine running for a long time at idle. The trimmer is designed for domestic use. Note! The engine reaches maximum power after 8-10 full refueling of the fuel tank. Trimmer OPERATION MODE STARTING THE ENGINE Before starting, check for the presence of fishing line in the trimmer head. Check the condition of the protective cover and the sharpness of the blade of the cutter. All trimmer work should be done in full throttle mode. Do not use the trimmer without the mower head guard installed. During operation, monitor the health and sharpness of the knife for trimming the fishing line. With the cover removed or malfunctioning, you cannot control the length of the fishing line of the trimmer head and, accordingly, the load on the engine and drive shaft. Starting A COLD ENGINE 1. Place the trimmer on a flat, horizontal surface. 2. Fill the fuel tank with freshly prepared fuel mixture. 3. Press the manual fuel pump 7-10 times until fuel appears in it. The pump is located in the lower part of the carburetor under the air filter housing (Fig. 6). Failure of the engine or drive shaft as a result of operation without a casing or with a faulty casing cannot be repaired under warranty. Note! When mowing, use the cyclic mode of operation: 1-2 minutes, full throttle, then 5-10 seconds, idle mode. Fig.6
13 13 4. Close the air damper. To do this, raise the flap lever 1 (Fig. 7). 6. Pull the starter handle until you feel resistance. Then pull strongly, but not sharply 4-5 times, until the first pop in the muffler. 7. After the first pop in the muffler, move the choke lever to the lower position. Then pull strongly, but not sharply 1-2 times, the engine should start. 8. After starting, warm up the engine for 1 minute. 1 Always select the free play of the starter cord at startup. Never pull the starter cord to the end; there is a danger of the cord breaking or damage to the parts of the starter group. Never let the starter handle up when starting up. Danger of starter breakdown. Failure to comply with these instructions often leads to breakdown of the starter and cannot be repaired under warranty. Fig. 7 5. Set the ignition switch to the “start” position (Fig. 8a). Holding the locking lever (C) Fig. 8, press the trigger. To facilitate starting, lock the gas trigger with the stopper (B) Fig. 8. A B C If the engine does not start, it is possible that you missed the first flash and the candle was filled with gasoline. In this case, the following steps must be performed: 1. Remove and dry the spark plug. 2. Set the ignition switch to the “stop” position. 3. Turn the trimmer upside down with the candle hole and, pulling the trigger, pull the starter grip several times to remove excess fuel from the cylinder. 4. Replace the candle. 5. Without closing the air damper, repeat the start-up procedure. Fig. 8 STARTING A HEATED ENGINE When starting a warm engine, do not close the air damper. To facilitate starting, you can lock the gas trigger in the pressed state. Otherwise, the starting procedure is the same as on a cold engine.
14 14 STOPPING THE ENGINE To stop the engine, release the throttle trigger, put the engine in idle mode and let the seconds run. Then turn the switch to the “Stop” position. Idling mode is necessary in order to reduce the temperature inside the engine. Instantly stopping the engine can lead to a sharp increase in temperature inside the engine and its failure. Before starting work, it is advisable to put on a shoulder strap and hang a trimmer on it without starting the engine. This will allow you to calmly adjust the belt in shape and height, adjust the position of the cutting headset relative to the surface of the earth. The mowing head must rotate parallel to the ground. When mowing tall and / or soft vegetation, make sure that mowed grass is not wound around the mowing head. This complicates the rotation of the drive shaft and increases the load on the engine itself. Keep the mowing head clean during operation. The grass wound on the mowing head can lead to heating and melting of the head, breakage of the drive shaft, overheating of the engine and its failure. Damage due to this reason cannot be repaired under warranty. During operation, it is recommended to keep the trimmer in front of you, tilting so that the lower part of the cutting mechanism does not touch the ground, and the tip of the cord is at the desired cutting height. The trimmer should be held so that the cutting of grass occurs in the direction away from the operator (Fig. 9). Fig. 9 When processing areas adjacent to fences, fences, stone walls and foundations, the trimmer should be moved slowly, trying to cut the grass as close to the obstacle as possible, without touching it. Otherwise, winding and breaking of the cord may occur. When processing areas around trees, the trimmer should be moved slowly and carefully so that the cord does not touch the tree trunks. When mowing, the tree is circled in a circle from left to right. The grass is cut off with the tip of the cord, slightly tilting the working mechanism forward. Particular care must be taken when cutting grass to the root. When mowing grass under the root, tilt the trimmer to the left by an angle of about 30 degrees. In this case, you must first adjust the position of the trimmer handle. Mowing under the root should not be carried out if there is a danger of crushed grass, soil particles getting into the operator, as well as other people or animals. It is recommended to mow tall grass in 2-3 steps, depending on the height of the grass. After finishing the work, clean the trimmer from the remains of the mowed grass, especially carefully clean the mowing head.
15 15 REPLACING THE LINE IN THE FORMER HEAD To replace the line, turn off the trimmer motor. A A B Fig. 11 Fix the ends of the fishing line in the special grooves on the reel (A) Fig. 11. Install the reel with fishing line in the head housing. Thread the ends of the line into the holes on the mower head housing. Fig. 10 Unscrew the nut securing the coil (A) Fig. 10. Remove the coil of the trimmer head and clean it of residual fishing line. Inspect head parts for damage. Damaged head parts must be replaced. Cut 2.5-3 meters of fishing line, fold it in half and align the ends. Insert the ends of the fishing line into the special grooves in the reel (B) Fig. 10. Wind the line tightly with an interference fit into the reel grooves. The winding direction is indicated by the arrow on the reel. After winding, cut the loop with the fishing line. Note! Do not forget to install the spring under the reel with fishing line. Tighten a nut of fastening of the coil. After that, pull the ends of the fishing line in order to release the fishing line from the special grooves in the reel.

17 17 BASIC MAINTENANCE WORKS CAUTION! All maintenance work is carried out with protective gloves on a cold engine. A AIR FILTER Dirty air filters can prevent air from entering the fuel mixture. To prevent engine malfunctions, regular maintenance of the air filter must be carried out. When working in dusty conditions, it is necessary to service the air filter more often. Never operate the trimmer without an air filter, with a dirty or damaged air filter. Dust and dirt will enter the engine, causing it to break. Failure of a carburetor or engine when operating without a filter, with a dirty or damaged air filter cannot be repaired under warranty. Fig. 12 B Press the latch at the top, remove the air filter cover (Fig. 12a) and remove the filter element (Fig. 12b). Wash the foam rubber filter in warm, soapy water, squeeze and dry. Moisten a foam filter with clean engine oil before installing. Wring out excess oil. A damaged or heavily soiled filter must be replaced.
18 18 FUEL FILTER Working with a dirty or damaged fuel filter leads to clogging of the fuel system parts, loss of engine power. If dirt enters the carburetor, it will fail. Failure of a carburetor or engine when operating without a filter, with a dirty or damaged fuel filter cannot be repaired under warranty. To check or replace the fuel filter: 1. Remove the fuel tank cap. 2. Bend a piece of soft wire into a small hook. 3. Hook the fuel hose with filter and pull through the filler neck. Spark PLUG. For efficient operation of the engine, the spark plug must have an appropriate glow number, spark gap between the electrodes. The candle should not have external mechanical damage. Recommended spark plug BM6A or its analogues. A WARNING! Never unscrew a candle until the engine has completely cooled down the danger of damage to the threaded part of the cylinder head. Note! Do not pull the fuel hose out of the tank completely. It is enough to pull out part of the hose with the filter. 4. Separate the filter with a twisting motion. 5. Install a new filter. Return the fuel hose to the tank. Make sure that the filter lies on the bottom of the tank. 6. Install the fuel tank cap. The fuel filter cannot be cleaned, only a replacement.
19 19 1. Disconnect the spark plug cap and remove dirt around the spark plug. 2. Unscrew the spark plug with a candle wrench. 3. Check the spark plug. If the electrodes are worn or damaged, replace the spark plug. 4. Measure a backlash between electrodes of a spark plug with a special probe. The clearance should be 0.6-0.65 mm. When increasing or decreasing the required clearance, it is recommended to replace the spark plug, since adjusting the clearance can lead to a change in the quality of sparking. 5. Gently twist the candle by hand. When installing a new spark plug, to ensure the required tightening, wrap the spark plug with a 1/2 turn key after fitting the bead of the spark plug on the sealing washer. When installing a used spark plug, to ensure the required tightening, wrap the spark plug with a wrench 1 / 4-1 / 8 of the turn after fitting the bead of the spark plug on the sealing washer. The spark plug must be securely tightened. An improperly wrapped or over tightened spark plug can cause engine damage. 6. After the spark plug is in place, tighten it with the spark plug wrench. 7. Install the cap on the candle.
