Explosion risk - Do not spray flammable liquids.
Never use acidic solvents containing solvents or undiluted! This includes gasoline, paint thinner, and heating oil. Spray can be highly flammable,
explosive, and toxic. Do not use acetone, undiluted acidic solvents as they will corrode the materials used on the equipment. Never use the
washer with flammable or toxic liquids, or liquids incompatible with normal operation.
Keep packaging films away from children, otherwise there is a risk of suffocation!
WARNING
In accordance with applicable regulations, cleaning machines must never be used on drinking water networks without a system separator.
Ensure that the connection to the building water installation in which the cleaning machine is operated is equipped with a compliant system
separator!
Water flowing through an anti-backflow valve is considered undrinkable.
To ensure applicable safety, only use original spare parts from the manufacturer or manufacturer approved.
WARNING
High-pressure hoses, fittings and couplings are important to machine safety. Use only hoses, fittings and couplings recommended by the
manufacturer.
WARNING
Improper use of the cleaning machine may result in serious injury or oxidation.
Store the washer away from children.
Bleed any residual pressure before disconnecting the hose from the product.
