To bleed air from the hydraulic drive, do the following:
- clean the tank and bleeder from dust and dirt;
- check the fluid level in the hydraulic reservoir and add fluid if necessary;
- put on the head of the fitting 9 (rice. 3-3) working cylinder hose and immerse its lower end in a vessel with hydraulic fluid (30-50 g);
- unscrew fitting 9 by 1/2-3/4 turn, sharply press and slowly release the pedal until air bubbles from the hose stop;
- pressing the pedal, wrap the fitting to the full. Remove the hose and put on the fitting cap.
If, despite prolonged pumping, air bubbles come out of the hose, check the tightness of the fastening of the connections, find out if there are any cracks or leaks on the tubes in the connections with the fittings. It is possible for air to enter through damaged O-rings in the master or slave cylinders.
When pumping:
- the fluid level in the hydraulic reservoir must be higher than the opening of the tube connecting the reservoir to the main cylinder;
- the end of the pumping hose must be constantly immersed in liquid;
- after pumping, bring the liquid level in the tank to the lower edge of the filler neck.
