Servicing & cleaning
• It is strictly prohibited to clean the excavator by steam injection equipment or a high-pressure washer within two
months after commissioning or repainting, so as to ensure proper
maintenance of finish paint.
• It is strictly prohibited to clean the excavator by any highly-corrosive cleaning agent. We recommend using
available cleaning agents for vehicles in the market.
• During cleaning by steam injection equipment, the temperature of
hot steam shall not exceed 80 ℃, and the injection pressure shall not exceed 70 bar.
• Do not clean the lining (such as the insulating layer) by water,
steam or high-pressure jet.
• During cleaning by water or steam jet, it is strictly prohibited to
spray it into the tail gas or air filter outlet.
• After every wet cleaning, apply lubricating grease to the excavator according to the lubrication chart and perform all operating
cycles, including auxiliary and traveling functions.
• After every cleaning, let the radiator gets dry naturally.
