After the first 2000 km, and then every 15,000 km, check the oil level in the crankcase and top up if necessary, check the operation of the gearbox for knocks and noises, check the tightness of the seals and the condition of the rubber protective cover of the gearshift rod.
Change the oil in the gearbox housing every 75,000 km.
Checking the oil level should be done on a cooled box to be sure that all the oil is glass from the walls of the crankcase and gears. To check the oil level, unscrew the control plug 2 (see fig. 59). The oil level should be at the bottom edge of the threaded hole. Add oil through the same hole. To drain the used oil, it is necessary to unscrew the plug, after warming up the oil with the car's mileage. Pour engine oil into the gearbox.
