| Check | ||
1 | Check the leak-tightness and condition of the reservoirs of fuel, compressed air, vacuum accumulator, oil, grease and brake fluid | If detecting a lack of leak-tightness or damage on any reservoirs, eliminate possible leakage, or replace the damaged reservoirs. | |
2 | Check the leak-tightness of the pneumatic and hydraulic components: valves of the air suspension and brake systems, brake master cylinder, disc brake calipers, braking power regulator valve, hydraulic system pumps and cylinders (e.g. clutch master and slave cylinders), as well as the shock absorbers | If detecting a lack of leak-tightness or damage on some components, eliminate possible leakage, repair, or replace the damaged components. | |
3 | Check the linings, dust-protectors and protective covers for possible damages and their correct fastening | If detecting a lack of leak-tightness or damage on protective covers, linings, and dust boost, check the corresponding components, such as articulations and ball joints. Renew and fasten correctly the dust protectors and protective covers, if necessary. | |
4 | Check the pneumatic suspension bellows for damages | Renew the pneumatic suspension bellows which have cracks, cut or with areas damaged by friction. |
