agents or chemicals may adversely affect the safety of the appliance.

To ensure the appliance safety only use original spare parts from the manufacturer or approved by the manufac- turer.

High pressure hoses, fi ttings and couplings are important for the safety of the appli- ance. Only use hoses, fi ttings and couplings recommended by the manufacturer.

Do not use the appliance if a supply cord or impor- tant parts of appliance are damaged, e.g. safety device , high pressure hose and trig- ger gun.

Remove the plug from the socket outlet during cleaning or maintenance and when replacing parts or converting the machine to another func- tion.

Appropriate ear protection must be used.

Never use the machine in an environment where there could be a danger of explo- sion. If any doubt arises, please contact the local authorities.

It is not allowed to clean asbestos-containing surfaces with high pressure.

Do not spray fl ammable liquids.

Always switch off the mains disconnecting switch when leaving the machine unat- tended.

This high pressure washer must not be used at tempera- tures below 0°C.

WARNING!

Inadequate extension cables can be dangerous. If an exten- sion cord is used, it shall be suitable for outdoor use, and the connection has to be kept dry and off the ground. It is recommended that this is ac- complished by means of a ca- ble reel which keeps the socket at least 60 mm above the ground. Cables on reels should always be completely unwound

to prevent the cable from over- heating.

Extension cables should com- ply with the below-mentioned requirements for length and cable dimensions.

1.0 mm²

max.

12.5 m

1.5 mm²

max.

20 m

2.5 mm²

max.

30 m

Only POSEIDON 2-17 X:

2.0 mm² máx.

12.5 m

2.5mm² máx. 20 m

If the electric cable is damaged, it must be re- placed by the manufacturer or his service agent or simi- larly qualified person in order to avoid a hazard.

Mains power connection

The following should be ob- served when connecting the high pressure washer to the electric installation:

Only connect the machine to an installation with earth con- nection.

The electric installation shall be made by a certifi ed elec- trician and comply with IEC 60364-1.

It is strongly recommended that the electric supply to this machine should include a re- sidual current device (GFCI).

Water connection Connection to the public mains according to regulations.

Machine not suit- able for connec- tion to the potable water mains.

This high pressure washer is only allowed to be connected with the drinking water mains, when an appropriate backfl ow preventer has been installed, Type BA according to EN 1717. The length of the hose between the backfl ow preventer and the

Poseidon 2

high pressure washer must be at least 10 metres to absorb possible pressure peaks (min diameter ½ inch).

Operation by suction (for example from a rainwater ves- sel) is carried out without back- fl ow preventer.

As soon as water has flown through the BA valve, this water is not considered to be drinking water any more.

IMPORTANT! Only use wa- ter without any impurities. If there is a risk of silt, sand or sediment in the inlet water (i.e. from your own well), an addi- tional filter should be mounted.

Safety devices

Locking device on spray handle (7a) (see illustration at the end of this manual):

The spray handle features a locking device. When the button is activated, the spray handle cannot be operated.

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.

Pressure safety device

An integrated hydraulic safety valve protects the system from excessive pressure.
