2.0 Instructions for use
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 in a safe condition.
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.
1. Only connect the machine to an installation with earth connection.
2. If you are in doubt about connections, please contact a qualified electrician for correct installation.
3. We 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.
4. The electric supply connection shall be made by an qualified electrician and comply with the latest edition
of the IEC Wiring Regulations.
Extension cable
If you want a wider radius of action ALTO recommend you to use an extension hose instead of an exten-
sion cable. If you want to apply an extension cable when operating a three-phase high pressure washer,
we recommend you to use the cable dimensions mentioned below: (The use of the stated cable dimen-
sions implies that the mains voltage is stable and corresponding to the voltage 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.
5. Extension cable, plug and socket should be waterproof.
6. Always 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.
7. Cable connections should be kept dry and off the ground.
8. Check 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 injury!
For your own and the safety of others the following precautions should always be observed:
1. WARNING! Never direct the water jet towards people, pets, electric wiring, or the machine itself.
2. WARNING! Never try to clean clothes or footwear on yourself or other persons.
3. We recommend you to wear goggles during operation.
4. Never work barefoot or with sandals.
5. Operator and anyone in immediate vicinity of the site of cleaning should take
action to protect himself from being struck by debris dislodged during operation.
6. According to regulations persons under the age of 18 must not operate cleaning machines with a working
pressure above 70 bar (applies to this machine).
7. The machine should be placed as far away from the cleaning site as possible.
8. Only let instructed personnel operate the machine.
9. Don't start the machine until the high pressure hose has been correctly mounted.
10. Spray handle and lance are affected by a backward force (thrust) during operation - therefore
always hold the spray lance firmly with both hands.
