3Cleaning Systems Safety Manual
English
Never operate the machine with a 
damaged high-pressure hose – 
it must be replaced immediately.
The high-pressure hose must be 
approved for the permissible excess 
pressure of the machine.
The permissible excess pressure, the 
maximum permitted temperature and 
the date of manufacture are stated on 
the cladding of the high-pressure hose.
The permissible pressure and date of 
manufacture are specified on the fittings.
Unsuitable detergents can cause 
damage to health, as well as to the 
machine and the object to be cleaned.
Contact a dealer if in doubt.
STIHL recommends the use of genuine 
STIHL detergents. Note the instructions 
for use (refer to the catalogue of 
chemical detergents).
Chemical detergents may contain 
physiologically harmful (toxic, caustic, 
irritant), flammable or explosive 
substances. Note the manufacturer's 
safety data sheets!
Clothing and equipment
Wear shoes with non-slip soles.
Wear goggles and 
protective clothing.
STIHL recommends that a boilersuit be 
worn in order to reduce the risk of injury 
due to accidental exposure to the high-
pressure jet.
Transporting the machine
When transporting the machine in or on 
a vehicle, it must be secured, e.g. with 
straps, so that it cannot slip or tip over.
The use of anti-freeze is recommended 
if the machine and accessories are to be 
transported at temperatures near or 
below 0 °C (32 °F); refer to the chapter 
"Storing the machine".
During work
Never spray water onto 
electrical appliances - 
risk of short-circuiting!
Never direct the high-
pressure jet or water hose 
against the machine itself 
or against other electrical 
appliances and 
equipment - risk of short-
circuiting!
Never direct the high-
pressure jet against 
yourself or other people, 
not even to clean clothing 
or shoes -
serious injuries may 
result!
Never use the machine 
when there are people without protective 
clothing in the working area.
Do not direct the high-pressure jet 
against animals.
Keep children, animals and bystanders 
at a safe distance.
