CAUTION!
High-pressure hoses, fittings and
couplings are important for the
safety of the cleaner. Use only
high-pressure parts approved by
the manufacturer!
The mains power lead must not
differ from the version specified
by the manufacturer and may only
be changed by an electrician.
Please contact the UNITOR ser-
vice department or an authorised
specialist work-shop for all other
maintenance or repair work!
Testing
The cleaner conforms to the
German „Guidelines for Liq-
uid Spray Jet Devices“. The
high-pressure cleaner must be
subjected to a safety examina-
tion in accordance with the „Ac-
cident Prevention Regulations
for Working with Liquid Spray
Jet Devices“ as required, but
at least every 12 months, by an
authorised inspector and this re-
port must be saved.
After all repairs or modifica-
tions to electrical equipment,
the protective conductor resist-
ance, the insulation resistance
and the leakage current must
be measured. Furthermore, a
visual inspection of the mains
power lead, a voltage and cur-
rent measurement and a func-
tion test must be carried out.
Our after-sales service techni-
cians are at your disposal as au-
thorised inspectors.
The complete „Accident Preven-
tion Regulations for Working
with Liquid Spray Jet Devices“
are available from the Carl Hey-
manns Verlag KG, Luxemburger
Strasse 449, 50939 Cologne or
from the appropriate associa-
tion of employers’ liability insur-
ances.
Unloader valve
Unacceptably high pressure is
fed back without residual pres-
sure 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.
Safety devices
Thermal sensor:
A thermal sensor protects the
motor against overloading. The
machine will restart after a few
minutes when the thermal sen-
sor has cooled.
Locking device on spray gun:
The spray gun features a lock-
ing device. When the pawl is
activated, the spray gun cannot
be ope rated.
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 aero-
sols use a respiratory mark
of class FFP 2 or higher.
