Safety Precautions
Warning!
 Inhalation of aerosols can be hazardous to health. Where applicable use a device in order to
avoid or reduce aerosols production, e.g., a shield covering the nozzle. For protection against
aerosols use a respiratory mask of class FFP 2 or higher.
 Always unplug the power plug before cleaning or maintenance and when replacing parts or
converting the machine to another function.
 Observe the national safety regulations issued, for example, by the employers liability insur-
ance association, social security institutions, occupational safety and health authorities or oth-
er organizations.
 Hold the spray lance firmly with both hands. The spray lance is affected by a thrust of up to
16,4N during operation.
 The operator and anyone in the immediate vicinity of the site of cleaning should take action to
protect themselves from being struck by debris dislodged during operation. Wear goggles dur-
ing operation.
 Disconnect from electrical power supply before carrying out user maintenance.
 To ensure the appliance safety only use original spare parts from the manufacturer or ap-
proved by the manufacturer.
 High pressure hoses, fittings and couplings are important for the safety of the appliance. Only
use hoses, fittings and couplings recommended by the manufacturer.
 Do not use the appliance if a supply cord or important parts of appliance are damaged, e.g.
safety device, high pressure hose and trigger gun.
 The appliance is only intended for cleaning outdoors.
 Appropriate ear protection must be used.
 Never use the machine in an environment where there could be a danger of explosion. If any
doubt arises, please contact the local authorities.
 It is not allowed to clean asbestos containing surfaces with high pressure.
 This high pressure washer must not be used at temperatures below 0°C.
 Voltage and frequency of the machine (see rating plate) must match the voltage of and fre-
quency of the mains supply.
 Only connect the machine to electrical installation made by a certifi ed electrician and com ply
with IEC 60364-1.
 It is recommended that the electrical supply to the machine should include a residual current
device that will interrupt the supply if the leakage current to earth exceeds 30 mA for 30 ms.
