Starting the engine if necessary This model is fitted with a semiautomatic decompression valve (1) to make starting easier. Depressing it reduces the force needed for compression, so little force is needed to accelerate the engine to its starting speed. The high pressure in the combustion chamber after the first ignition automatically closes the decompression valve (button pops out). CAUTION: Observe the SAFETY INSTRUCTIONS on page 5 and 6! Start the Power Cut only after complete assembly
