Symbols used to mark instructions
Do not let children or people
who have not read the instruction manual ope rate the machine.
Before starting up your machine please check it carefully
for any defects. If you fi nd any,
do not start up your machine
and contact your Nilfi sk-ALTO
distributor.
Especially check:
The insulation of the electric
cable should be faultless
and without any cracks. If the
electric cable is damaged,
an authorized Nilfi sk-ALTO
distributor should replace it.
Before starting up
your high-pressure washer for
the fi rst time, this
instruction manual
must be read through carefully.
Save the instructions for later
use.
Safety instructions
marked with this
symbol must be
observed to pre-
vent danger to persons.
WARNING!
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 operation.
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 during operation.

Never use the machine in
an environment where there
could be a danger of explosion. If any doubt arises,
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.
Never let any persons stay
under the product when
stored on the wall.
WARNING!
Inadequate extension cables
can be dangerous. Cables on
drums should always be completely unwinded to prevent the

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.
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 regu-
lations.
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
(5a) (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.

coupling
1. Click the hose reel handle
on to the trolley handle (no
screws).
1. Screw the quick coupling (12)
tight on to the water inlet (2).
Note: The inlet fi lter must always be fi tted 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

4.1 Mounting of spray
lance
1. Push the spray lance (3) into
the spray gun (5).
4.2 Water connectionlations.
An ordinary 1/2" garden hose of
min. 10 m and max. 25 m will
be suitable.

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 penetrat-
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

4.3 Telescopic handle
The machine features a telescopic handle. To raise or lower
the handle, press the knob (13)
and move the handle upwards
or downwards. When a click
is heard, the handle is in right
position.
4.4 Start and stop of the machine (when connected
to a water supply)
The spray lance is affected
by a thrust during operation - therefore always hold it
fi rmly with both hands. IMPOR-
TANT: Point the nozzle at the
ground.
1. Check that the machine is in
upright position.
NOTE: Do not place the ma-
chine 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 ma-
chine 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 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.
4.5 Start the machine (when
connected to open containers (suction mode))
4.6 Pressure regulation on
the Flexopower 3000
nozzle
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
Low pressure
water contains impurities.
2. Turn the start/stop switch 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.
The pressure can be regulated
on the Flexopower nozzle.

4.7 Stationary useIf mounting a special wall hook
(not standard), the pressure
washer can be used as a stationary solution meaning that it
can be operated while hanging
on the wall.
Only mount the wall hook on a
sturdy wall. Adjust the length
of the screws and size of rawlplugs to the type of wall.
Important: The
bearing capacity
of the wall hook
is max. 30 kg.

5 After using your pressure washer
5.1 Storing the washerThe machine should be sto-
red in a frost-free room!
Pump, hose and accessories
should always be emptied of
water prior to storing as follows:
5.2 Winding up of electric
cable and high pressure
hose
1. Stop the machine (turn the
start/stop switch (1) to position “O” and detach water
hose and accessory.
2. Restart the machine and
activate the trigger. Let the
machine run until no more
water runs through the spray
gun.
14
3. Stop the machine, unplug
and wind up hose and cable.
4. Place spray handle, nozzles
and other accessories in the
holders of the machine.
Should the machine by mistake
be frozen, it will be necessary
to check it for damage.
NEVER START-UP A FROZEN
MACHINE.
Frost damages are not
covered by the guarantee!
To avoid accidents, the electric
cable and the high pressure
hose should always be winded
carefully up.
1. Wind up the electric cable on
the appropriate hooks. Builtin clip for good holding.
The lower hook (14) can be
turned to release the electric
cable.
2. Coil the high pressure hose
up on the hose reel (10).
5.3 Storage of accessoriesThe standard accessories
6/7
6/7
(spray gun and spray lance
(6/7)) can be stored on the
pressure washer.
The nozzle cleaning tool (8) can
also be stored on the product.
