| GENERAL INFORMATION |
Objective indicators of the general condition of the engine, need of major maintenance of the engine with complete dismantling, results of measurements of pressure of oil and a compression in cylinders are indicating. The sensor of pressure of oil on the M10 models will screw in the left back part of a head of cylinders, on the M20 models – in the block of cylinders under the oil filter, on М40 – in a back part of the case of the oil filter. For measurement of pressure turn out the sensor and screw the confided manometer.
