Both materials can be easily separated from each other and reused or recycled. Operating materials Motor oil The high-pressure module contains motor oil. When changing the oil, the waste oil must be handed in to a waste oil collection point or a disposal company. The same applies for oil or an oil and water mixture collected in case of leaks. i Important! Waste oil must only be disposed of at the collection points provided. Please hand in all waste oil there. Conta- minating the environment with waste oil is a punishable offence. Cleaning agent Kärcher cleaning agents are separator friendly (ASF). This means that they do not hinder the function of an oilseparator. A list with recommended cleaning agentsis given in the „Accessories“ section.

Failure to obser- ve this information can lead to slight injuries or damage to property. i Important! Denotes tips for use and important information. 3. Hazard sources The water in the high-pressure module is highly-pressuri- sed in places. It can escape from damaged components. This results in potential injury and possible burn hazards. 5.961-163 A 2006087 (09/03) A1 English Operating instructions HD 9000 E USA A. For your safety General hazards ! Hazard! n Injury hazard due to escaping, possibly hot waterjet. Check the high pressure hose, pipes and fittings for damage before each use. Immediately renew any leaking components and seal leaking connections. Only original Kärcher high-pressure hoses are optimal- ly designed for the system. We will not accept any responsibility if other hoses are used. Even after being switched off at the EMERGENCY STOP button or master switch, the high-pressure module is still highly pressurised. Release the pressu- re at the end of operation. n Burn hazards due to hot system parts. Do not touch any non-insulated pipes and hose cou- plings when running the system with hot water. n Injury hazard due to parts flying off the system. Fragments or objects flying off the system can cause injuries to people or animals. Never direct the water jet at fragile or loose objects. n Explosion hazard. This high-pressure module must not be run in potenti- ally explosive rooms. n Explosion hazard. Do not process any liquids other than water with the module, in particular no combustible or caustic liquids. Do not use any cleaning agents containing explosive, highly flammable or poisonous substances, e.g.: – benzine – heating oil and diesel fuel – solvents – liquids containing solvents – undiluted acids – acetone. If you are uncertain ask the manufacturer. Check the high-pressure hose, pipes with fittings and spray lance for damage before each use.
