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.
The appliance is intended to clean cars and garden etc.. Appropriate ear protection has to 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
This high pressure washer must not be used at tempera- tures below 0°C.
WARNING!
Inadequate extension cables can be dangerous. Cables on drums should always be com- pletely unwinded to prevent the cable from overheating.
Extension cables should be of a watertight construction and comply with the
1.0 mm² | max. | 12.5 m |
1.5 mm² | max. | 20 m |
2.5 mm² | max. | 30 m |
Cable connections should be kept dry and off the ground. If the electric cable is damaged, it must be re- placed by the manufacturer or his service agent or simi- larly qualifi ed 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.
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.
This high pres- sure 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 backfl ow pre- venter can be ordered under number 106411177. The length of the hose between the back-
flow preventer and the high pressure washer must be at
least 10 metres to absorb pos- sible pressure peaks (min diam- eter ½ inch).
Operation by suction (for ex- ample from a rainwater vessel) is carried out without backfl ow preventer. Recommended suc- tion set: 126411387.
As soon as water has fl own 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 running sands in the inlet water (i.e. from your own well), an additional fi lter should be mounted.
Repair and maintenance WARNING! Always remove the electric plug from the socket be- fore carrying out maintenance work on the machine.
Safety devices
Locking device on spray gun (7a) (see foldout at the end of this manual):
The spray gun features a lock- ing device. When the pawl is activated, the spray gun 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.
