Checking the drum drive motor
• Unscrew the high pressure hoses from the drum drive motor and close them with suitable plugs
• Perform a high pressure test (Fig. F9)
If the specified pressure values are reached after disconnecting the drum drive motor, whereas they
have not been reached while the motor was still connected, the drum drive motor is defective. If the
specified pressures are not reached, the axle drive motor or the travel pump must be defective
