First, you can not immediately turn off the engine: after a long period of high-speed operation, you can not immediately turn off the engine. When the engine is working, a part of the oil supply turbocharger rotor bearing lubrication and for cooling. Is running after the engine suddenly shut down, the oil pressure quickly drop to zero, the high temperature of the turbo part of the supercharger to the middle, the bearing support shell in the heat can not be quickly taken away, while the supercharger rotor is still in the inertia of high-speed rotation, therefore, the engine hot engine state if suddenly shut down, will cause the turbocharger stagnant oil overheating and damage to bearings and shafts.
　　Second, keep clean: when dismantling the supercharger, to keep clean, the pipe joints must be blocked with clean cloth to prevent debris from falling into the supercharger, damaging the rotor. Maintenance should be careful not to collide with damage to the impeller, if you need to replace the impeller, it should do a dynamic balance test. After the reassembly is complete, to remove the blockage.
　　Third, you can not start the car on the go: after the engine is started, especially in winter, should let it idle for a period of time, so that the supercharger rotor high-speed operation before the lubricant fully lubricated bearings. So just after the start must not blast the throttle to prevent damage to the supercharger oil seal.
