- Always clean the area adjacent to the connections and hose fittings on any and all components being removed prior to starting repair work on ABC systems.
Use caution to ensure that residue and contaminants from repair operations, such as metal shavings, lint, etc., do not enter the ABC system through connections and hose fittings.
- Use the bleed screw (56, 57) to drain the hydraulic fluid, then dispose of the fluid according to regulations.
- Adding hydraulic fluid.
The funnel with filter must not be used with other service fluids. To help prevent damage due to dirt entering the ABC system, always store this filter-equipped funnel in a separate cabinet.
- The ABC fluid-return circuit contains a distribution valve with a booster valve and a temperature sensor.
To prevent the body from dropping too quickly, open bleed screws (56, 57) carefully to limit the flow of the emerging hydraulic fluid.
- Because even minute particles and traces of contaminants can lead to ABC failure, always pay scrupulous attention to cleanliness when adding hydraulic fluid!
- When bleeding air from the ABC system, and whenever allowing the pump motor to run, always ensure that the fluid reservoir (2) contains an adequate supply of hydraulic fluid, and verify that the tandem pump (1) is not ingesting air.
- Before leaving the vehicle parked for extended periods, always bring the front road wheels to their straight-ahead position. Should the ABC system subsequently suffer an internal pressure loss, this precaution will protect vehicle bodywork against contact and possible damage stemming from contact with front wheels that are turned to an angle.
