The environmental policy of ALTO
ALTO has made it a natural part of the concept of the
company to reduce the effect on our environ-ment as much
as possible. This plan is effected through a constant devel-
opment in all branches of the company so that the greatest
number of elements in our high pressure washers affects
the environment to a minimum.
This product too is characterised by the attitude of ALTO
towards the environment.
The majority of the incorporated plastic compo-nents and
first and foremost the cabinet is made of the environmen-
tally desirable polypropylene plastic material. The applied
form of the substance can be regranulated, which means
that the substance can be used for other plastic materials
upon discarding.
To ensure the possibilities of recycling the
plastic materials of the product, they have
been marked with a recycling symbol and the
type of material.
It is also a part of our concern for environ-
mental problems that the high pressure
washer is maintenance-free, meaning that the oil in the
high pressure pump will not have to be changed. The oil is
in a closed system and is only changed by an eventual
servicing.
For the production of this high pressure washer the latest
technique and technology has been applied. The consump-
tion of unnecessary subsidiary materials has been mini-
mized, and during the final test of the product the test water
is recycled.
United Kingdom: Health and Safety at work Act 1974 Guidance note p.m. 29
This act imposes certain obligations with regard to safety on both operators and suppliers of machines used in the course of work.
ALTO's policy has always been to ensure, so far as is reasonably practicable, that all ALTO products are safe and without risk to
health when properly used.
Although the proper use will vary from machine to machine there is a constant factor which cannot be overemphasized, namely the
need for a good standard of personal and industrial operation and installation.
ALTO always endeavours to provide customers with adequate information on the products they are using, by the issue of descrip-
tive literature which is constantly being reviewed and updated.
We would also like to remind you of the importance of avoiding misuse and the need to dissemi-nate all relevant information to
individual employees.
If you have any doubts or problems relating to the correct installation, application, storage or handling of any of the products please
do not hesitate to contact your local ALTO distributor.

2.0 Instructions for use Safety precautions and warnings GB
Before starting up your high pressure washer for the first time, we advise you to read through the following
sections: 2.0 Instructions for use and 3.0 Operating instructions and to follow all instructions to ensure the
protection of user, surroundings and machine.
2.1 Starting-up
Upon the unpacking of your machine please check it for any defects. If you find any, we kindly ask you to
contact your ALTO distributor.
Check the electric cable
The insulation of the electric cable should be quite faultless and without any cracks.
Please contact a qualified electrician or the nearest ALTO distributor if any doubts arise.
Check the voltage
Check that the voltage stated on the model tag corresponds to your mains voltage.
Power consumption, fuse
Check the power consumption stated on the model tag and then check correct prefuse.
Mains power connection
Faulty connection of the machine can cause electric shock.
lOnly connect the machine to an installation with earth connection.
lIf you are in doubt about connections, please contact a qualified electrician for correct installation.
lWe recommend you to connect the machine to a power source with a Residual Current Device (RCD),
which will disconnect the power supply if the leakage current exceeds 30 mA for 30 milli seconds.
lThe electric supply connection shall be made by a qualified electrician and comply with the latest edition
of the IEC Wiring Regulations.
Extension cable
If you want a wider radius of action ALTO highly recommend you to use an extension hose instead of an
extension cable. Where impracticable seek advice of a qualified electrician or the nearest ALTO distributor.
If you want to apply an extension cable when operating a three-phase high pressure washer, we recom-
mend you to use the cable dimensions mentioned below: (The use of the stated cable dimensions implies
that the mains voltage supplies a stable voltage corresponding to that stated on the model tag).
NOTE: If an extension cable is required it must be earthed and connected through the plug to the
earth cable of your supply network in accordance with prescribed safety regulations.
lExtension cable, plug and socket should be waterproof.
lAlways use a cable similar to the one mounted on the machine i.e. with earth connection and for outdoor
use. If you are in doubt, please contact a qualified electrician or the nearest ALTO distributor.
lCable connections should be kept dry and off the ground.
lCheck extension cables before usage. Don’t use damaged cables.
2.2 Operation
This machine produces a high pressure jet and operation contrary to the instructions can cause severe
injuries!
For your own and the safety of others the following precautions should always be observed:
lWARNING! Never direct the water jet towards people, pets, electric wiring, or the
machine itself.
lWARNING! Never try to clean clothes or footwear on yourself or other persons.
lWe recommend you to wear goggles during operation.
lNever work barefoot or with sandals.
lOperator and anyone in immediate vicinity of the site of cleaning should take action to protect himself
from being struck by debris dislodged during operation.

Safety precautions and warnings GB
lAccording to regulations persons under the age of 18 must not operate cleaning machines with a work-
ing pressure above 70 bar (applies to this machine).
lThe machine should be placed as far away from the cleaning site as possible.
lOnly let instructed personnel operate the machine.
lDon’t start the machine until the high pressure hose has been correctly mounted.
lSpray handle and lance are affected by a thrust during operation - therefore always hold the
spray lance firmly with both hands.
lAt intervals during operation, the machine should be stopped and the spray handle secured
against inadvertent use by locking trigger with locking device.
lOnly activate the trigger by hand. Never tie it up or fix it in any other way.
lAvoid damage to the high pressure hose such as running over by a car, squeezing, pull, knots/kinks etc.
and keep it away from oil and sharp or hot objects, as such may cause the hose to burst.
lDanger of scalding! Never dismount the high pressure hose or the water inlet hose while the machine
is in operation. Disconnect the cleaner, shut off the water supply and activate the spray handle before
dismounting the high pressure hose or the water inlet hose.
lNever jerk the cable to disconnect the plug from socket.
lAlways disconnect the plug from socket prior to disconnecting any extension cables.
lAvoid damage to the electric cables such as running over by a car, squeezing, pull, knots etc. and keep
them away from sharp or hot objects.
lAccording 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.
Important: OFFSHORE
Never use the machine in an environment where there could be a danger of explosion
(according to EN-50014).
lWARNING! High pressure hoses, nozzles and connections are important for safety when operating the
machine. Only use the high pressure hoses, nozzles and connections prescribed by ALTO.
lFor safety reasons only use original ALTO accessories and spare parts.
lIn icy conditions never start the cleaner until machine, hoses and accessories have thawed. Otherwise
the machine could be damaged.
lThe cleaner should not be covered during operation.
2.3 Safety devices on the machine
Circulation valve (safety valve)
The pressure side of the high pressure pump is fitted with a circulation valve (safety valve). This valve
circulates the water back to the suction side of the pump when the spray handle is closed or if a nozzle is
blocked. The circulation valve has been constructed as a safety function ensuring that the pressure will
never exceed the working pressure by more than 25 bar. At this pressure the circulation valve will auto-
matically switch from high pressure to circulation mode.
The pump will overheat if it is not disconnected within 10 min. (5 min. at 60°C inlet water) and thus it may be
damaged. The circulation valve ensures that the machine becomes devoid of pressure when it is stopped.
Motor protection
The electric motor features an overcurrent release for protection of motor against overloading. In the case
of increased power consumption (maloperation) the power for the motor will automatically be disconnected.
2.4 General
lIt is not allowed to clean asbestos-containing surfaces with high pressure, unless using special equipment.
lPersons under the influence of alcohol, drugs and medicine should not operate the machine.
lNever touch plug and socket with wet hands.
lWARNING! This machine has been constructed for use with ALTO detergents. The use of other deter-
gents or chemicals may cause problems as to the operation and the safety.
lWhen using detergents the instructions should always be strictly observed.
lAlways unplug before cleaning and maintenance of the machine.
lDon’t use the machine if the electric cable or important parts of the equipment are damaged - i.e. safety
devices, high pressure hoses, spray handles, cabinet.
lThe most efficient cleaning is obtained if you adjust the distance to the surface which is to be cleaned.
Thus you will also avoid damaging the surface.
