tion against hydrous aerosols.
• This machine has been designed for use with the cleaning agent
supplied or recommended by the manufacturer. The use of other
cleaning agents or chemicals may adversely affect the safety of
the machine.
• Risk of explosion – Do not spray flammable liquids. Do not clean
delicate parts made of rubber, fabric, etc. with the jet nozzle.
Keep some distance between the jet nozzle and surface in order
to prevent the surface from damage.

4 Electrical connection

The electric supply connection shall be made by a qualified electri-
cian and comply with IEC 60364-1. It is recommended that the elec-
tric supply to this machine should include either a residual current
device that will interrupt the supply if the leakage current to earth ex-
ceeds 30 mA for 30 ms or a device that will prove the earth circuit.
Switching on the cleaner may cause voltage fluctuations. Voltage
fluctuations should not occur if the impedance at the transfer point is
less than 0.15 Ohm. If in doubt ask your local electricity supplier.
WARNING
• Inadequate extension cords can be dangerous. If an extension
cord is used, it shall be suitable for outdoor use, and the connec-
tion plug has to be kept dry and off the ground. It is recommend-
ed that this is accomplished by means of a cord reel, which keep
the socket at least 60mm above the ground. Always unwind cord
from the reels completely to prevent the power cord overheating.
• Disconnect the power cord from the power source by pulling the
plug only (do not pull or tug the power cord).

5 Safety devices

Thermal sensor: A thermal sensor protects the motor against over-
loading. The machine will restart after a few minutes when the ther-
mal sensor has cooled.
Unloader valve: Unacceptably high pressure is fed back without re-
sidual pressure via a bypass line into the intake line of the pump
when the safety device is tripped.
The unloader valve is set and sealed at the factory and must not be
adjusted.
Locking device on spray handle: The spray handle features a locking
