 High pressure jets can be

dangerous. Never direct the
water jet at persons, pets,
live electrical equipment or
the machine itself.

 Never try to clean clothes or

footwear on yourself or other
persons.

 Hold the spray lance fi rmly

with both hands. The spray
lance is affected by a thrust
of up to 16.4 N during ope–
ration.

 The operator and anyone in

the immediate vicinity of the
site of cleaning should take
action to protect themselves
from being struck by debris
dislodged during operation.
Wear goggles and protection
clothes during operation.

or approved by the manufac­turer.

 High pressure hoses, fi ttings

and couplings are important
for the safety of the appli­ance. Only use hoses, fi ttings
and couplings recommended
by the manufacturer.

 Do not use the appliance

if a supply cord or impor­tant parts of appliance are
damaged, e.g. safety device ,
high pressure hose and trig­ger gun.

 The appliance is intended to

clean cars and garden etc..

please contact the local
authorities.

 It is not allowed to clean

asbestos- containing surfaces
with high pressure.

 This high pressure washer

must not be used at tempera­tures below 0°C.

WARNING!

Inadequate extension cables
can be dangerous. Cables on
drums should always be com­pletely unwinded to prevent the
cable from overheating.

Extension cables should be of
a watertight construction and
comply 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

 Cable connections should be

kept dry and off the ground.

 If the electric cable is

damaged, it must be re­placed by the manufacturer
or his service agent or simi­larly qualifi ed person in order
to avoid a hazard.

Mains power connection

The following should be ob­served when connecting the
high pressure washer to the
electric installation:
 Only connect the machine to

an installation with earth con­nection.

 The electric installation shall

be made by a certifi ed elec­trician.

 It is strongly recommended

that the electric supply to this
machine should include a re­sidual current device (GFCI).

Water connection

Connection to the public mains
according to regulations.

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 backfl ow pre­venter can be ordered under
number 106411177. The length
of the hose between the back­fl ow preventer and the 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 vessel)
is carried out without backfl ow
preventer. Recommended suc­tion 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 wa­ter 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 be­fore 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 lock­ing device. When the pawl is
activated, the spray gun cannot
be ope rated.

Thermal sensor:

A thermal sensor protects the
motor against overloading. The
machine will restart after a few
minutes when the thermal sen­sor has cooled.

Pressure safety device

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

must always be fi t-

ted in the water

inlet pipe to fi lter

out sand, lime stone

and other impurities as
these will damage the pump
valves.
Caution: Failure to fi t the fi lter
will invalidate the guarantee.

4.3 Water connection An ordinary 1/2" garden hose of
min. 10 m and max. 25 m will

be suitable.

NOTE: Connec­tion to the public
mains according
to regulations.

IMPORTANT!
Only use water
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.

1. Let the water run through the
water hose before connecting
it to the machine to prevent
sand and dirt from penetrat­ing the machine.

Note: Check that the fi lter is

fi tted in the water inlet pipe
and that it is not clogged up.

2. Connect the water hose to
the water supply by means
of the quick connector (inlet
water, max. pressure: 10 bar,
max. temperature: 40°C).

3. Turn on the water.

4.4 Start and stop of the
machine (when con-

nected to a water supply)

The spray lance is affected
by a thrust during operation ­therefore always hold it fi rmly
with both hands. IMPORTANT:

Point the nozzle at the
ground.

1. Check that the machine is in
upright position.

NOTE: Do not place the

machine in high grass!

2. Release the trigger lock.

3. Activate the trigger of the
spray gun and let the water
run until all air has escaped
from the water hose.

4. Turn the start/stop switch (1)
to position"I".

5. Activate the trigger of the
spray gun.

Always adjust the distance and
thus the pressure of the nozzle
to the surface, which is to be
cleaned.

Do not cover the machine
during operation.

Note: If the ma­chine is left or not

used for 5 min­utes, it must be switched off on
the start/stop switch "O" (1):

1. Turn the start/stop switch (1)

to position"O".

2. Disconnect the electrical plug

from the socket.

3. Shut off the water supply and

activate the trigger to relieve
the machine of pressure.

4. Lock the spray gun.

When releasing the trigger of
the spray gun, the machine
automatically stops. The ma­chine will start again when you
re-activate the spray gun.

9

4.5 Start the machine (when
connected to open con­tainers (suction mode))

The washer can take in water
from a rain water tank as an
example. The hose for the wa­ter supply must not be too long,
approx. 5 m.

Make sure that the water tank
is not placed on a lower level
than the machine.

1. Place the other end of the
water hose in the water tank.
Use an external fi lter if the
water contains impurities.

2. Turn the start/stop switch (1)
to position"I".

3. Activate the trigger of the
spray gun and let the water
run, until the air has escaped
from the water hose and the
pump.

4. Mount spray lance and
nozzle.

5 Fields of application and working
methods

5.1 General Effi cient high presure cleaning is achieved by following a few guide-

lines, combined with your own personal experience of specifi c
cleaning tasks. Accessories and detergents, when correctly cho­sen, can increase the effi ciency of your pressure washer. Here is
some basic information about cleaning.

5.1.1 Detergent and foam Foam or detergent should be applied onto dry surfaces so that the

chemical product is in direct contact with the dirt. Detergents are
applied from bottom to top, for example on a car bodywork, in order
to avoid "super clean" areas, where the detergent collects in higher
concentration and streams downwards. Let the detergent work for
several minutes before rinsing but never let it dry on the surface be­ing cleaned. Note: It is important that the detergents do not dry up.
Otherwise the surfac that has to be cleaned can be da maged.

5.1.2 Mechanical effect In order to break down tough layers of dirt, additional mechanical

effect may be required. Special wash brushes offer this supplemen­tary effect that cuts through dirt (especially by car washing).
