l Avoid damage to the high pressure hose such
as running over by a car, squeezing, pulling,
knotting/kinking etc. and keep it away from oil
and sharp or hot objects, as such may cause the
hose to burst.
l Never dismount the high pressure hose while
the machine is in operation. Disconnect the
machine and the water connection before dis-
mounting the high pressure hose.
l Never jerk the cable to disconnect the plug
from the socket.
l Disconnect from the electrical power supply
before disconnecting any extension cables.
l Avoid damage to the electric cables such as
running over by a car, squeezing, pulling,
knotting etc. and keep them away from sharp
or hot objects.
l Never use the machine in an environment
where there could be a danger of explosion.
l WARNING! High pressure hoses, nozzles and
couplings are important for the safety of the
machine. Only use nozzles, high pressure
hoses and couplings prescribed by ALTO.
l To ensure the machine safety, use only original
ALTO accessories and spare parts.
l The machine should not be covered during
operation.
l According to the legislation in many countries
it is forbidden to use the machine in an
environment where there could be a danger of
explosion. If any doubt arises, please contact
your local authorities.
General
l It is not allowed to clean asbestos-containing
surfaces with high pressure.
l WARNING! This machine has been designed
for use with ALTO detergents. The use of
other detergents or chemicals may adversely
affect the operation or the safety of the ma-
chine.
l When using detergents, the instructions should
always be strictly observed.
l If the electric cable is damaged, it should be
replaced by ALTO trained service personnel or
a similarly trained person to avoid any dange-
rous situation.

Safety devices on the machine
Safety valve (by-pass valve)
The by-pass valve also functions as a pressure
reducing valve. The valve will open when the
trigger is released and the water is recirculated
through the pump.
NOTE! The high pressure pump will overheat
and thus it may be damaged if running by-pass
(i.e. the water being re-circulated in the pump) for
more than 2 minutes with water of a temperature
of 8°C. If the temperature of the water is higher,
this time will be reduced.
Thermal sensor
The washer features a thermal sensor for protec-
tion of the motor against overloading. In the
event of an increased power consumption, the
power supply for the motor will automatically be
disconnected. The machine will restart after a
few minutes when the thermal sensor has cooled.
other important parts of the system are
damaged, e.g. safety devices, high pressure
hoses, spray handle, cabinet.
adjust the distance to the surface which is to be
cleaned. Thus you will also avoid damaging
the surface.
