Prevent inadvertent startups of the appli- ance during Maintenance Procedures via third persons by attaching signs on the appliance and the spray unit.

If the appliance must be started up for maintenance procedures, a second person must be present for safety rea- sons.

Water under high pressure can pene- trate the skin and cause severe injuries and infections. Stay away from leaks and do not search for leaks by hand.

Do not use flammable detergents to clean the appliance.

After completing the maintenace work, check all safety devices for correct in- stallation and proper function.
