3 Before starting the machine
3.1 Transport and assembly
1. The safest way to lift the ma-
chine is to use a fork-lift truck
The arrows in the illustration
indicate the best places to
position the fork.
Every fuel-burning appliance,
such as pressure washers, de-
pends upon a proper mix of fuel
and air (by weight) for proper
combustion. Therefore some
adjustment of the air supply to
the burner may be necessary to
take account of altitude and the
resulting air pressure. This is
true whether your fuel is ‘Natural
gas’, Propane or Diesel.
Your Nilfisk hot water pressure
washer was thoroughly tested
and adjusted for optimum per-
formance before it left our fac-
tory. The factory is located at
approximately 200m (650 ft)
above sea level, and the com-
bustion settings are optimal for
that elevation.
If your location is higher than
1200m (3900 ft) above sea
level, your burner may require
re-adjustment for proper
performance and best fuel
economy. Contact your Dealer
or Nilfisk for assistance.
3.2 Set the brake (only
machines with wheels
1. Before using the cleaner for
the first time, check it care-
fully for any faults or damage.
2. Run the machine only when
it is in perfect working condi-
tion.
3. Set the brake.
3.3 Fill up fuel tank With the machine cold and
turned off:
1. Fill fuel tank from a clean
container with a fresh fuel or
Diesel EN 590 (Diesel with
bio diesel content up to 7%).
See chapter 1.
Tank capacity max. 57 l.
Use clean fuel only, free of
moisture and contamination.
Contact your dealer for fuel
source and type recommenda-
tions.

3.5 Connecting the water
supply
1. Attach hose coupling found
with Owners Manual to the
water supply hose.
2. Rinse the water supply hose
briefly in order to prevent
sand an other dirt particles
entering into the machine.
3. Attach hose coupling to inlet.
4. Open water supply faucet.
NOTE!
See section 9.4 Technical Data
for required quantity of water
and water pressure.
In the case of poor water quality
(sand, etc.), it is recommended
that an inlet water filter be in-
stalled.
Water supply hose should be
a reinforced hose and have a
minimum inside diameter of
3/4" (19 mm).
to 7% bio diesel) can be used
with the following restrictions:
Maximum storage time in high
pressure cleaner diesel tank: 1
month.
Diesel stored externally for more
than 6 months is not allowed to
be filled into Nilfisk high pres-
sure cleaners.
Diesel EN 590 from an open
container must not be used.
If the machine is to be opera-
ted at fuel stations or in other
potentially hazardous areas,
the machine may only be em-
ployed outside the hazard areas
defined in the German „Techni-
cal Guidelines for Inflammable
Fluids“ applicable at the point
of use due to the potential ex-
plosion hazard posed by the
burner.
NOTE!
At tempera-
tures below
8°C (46°F),
the fuel oil begins to solidify
(paraffin precipitation). This can
lead to difficulties in starting
the burner. Before the winter
months it is recommended that
a fuel conditioner/stabilizer be
added (available from the fuel
oil trade).
Filling up the engine with fuel,
see the enclosed instructions for
the engine.
1. Connect the high pressure
hose quick connector to the
high pressure nipple.

5 Applications and methods
5.1 Techniques
Efficient high pressure cleaning is achieved by following a few
guidelines, combined with your own personal experience of specific
cleaning tasks. Accessories and detergents, when correctly chosen,
can increase the efficiency of your pressure washer. Here is some
basic information about cleaning.
5.1.1 Soaking Encrusted or thick layers of dirt can be loosened or softened up by a
period of soaking. This is for example an ideal method within agricul-
ture – for example, within pig sties. The ideal soaking method can be
achieved by using foam or simple alkaline detergent. Let the product
lie on the dirty surfaces for about 30 minutes before pressure wash-
ing. The result will be a much quicker high pressure cleaning pro-
cess.
5.1.2 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 ap-
plied from bottom to top, for example on a automobile bodywork, in
order to avoid “super clean” areas, where the detergent may collect
in higher concentrations and streams downwards. Let the detergent
work for several minutes before rinsing before rinsing and never let it
dry on the surface being cleaned.
5.1.3 Temperature Detergents are more effective at higher temperatures. Greases, oils
and fats can be broken down more effectively at higher tempera-
tures also. Proteins can be cleaned at temperatures of around 60°C
(140°F). Oils and traffic film around 70°C (158°F), and grease can
be cleaned at 80°-90°C (176-194°F).
5.1.4 Mechanical Eff ect In order to break down tough layers of dirt, additional mechanical
effect may be required. Special lances and rotary or wash brushes
offer this supplementary effect that cuts through dirt.
5.1.5 High Water Flow or High pressure is not always the best solution and may also damage
High Pressure surfaces. The cleaning effect also depends upon water flow. Pres-
sure levels of around 100 bar (1450 psi) may be sufficient for vehicle
cleaning (in association with hot water) and higher flow levels give
the ability to rinse and flush away large amounts of dirt easily.

pre-spray with a product such as Allosil in order to
remove traces of insects etc, then rinse at low pres-
sure and apply normal car cleaning detergent. Let
detergents settle for 5 minutes before cleaning off.
Metallic surfaces can be cleaned using RimTop.
2. Proceed with cleaning using the high pressure
lance. Clean again from bottom to top. Use ac-
cessories to clean in difficult to reach places. Use
brushes in order to add a mechanical cleaning ef-
fect. Short lances can help for cleaning of motors
and wheel arches. Curved lances or undercarriage
washers can be valuable for the cleaning of car
underchassis and wheel arches.
3. Clean fragile areas such as motors, rubber at lower
pressure levels to avoid damage.
4. Apply a liquid wax using the pressure washer in
order to protect the bodywork from pollution.

1. Apply thick foam over the surfaces to be cleaned.
Apply on dry surfaces. Apply from top to bottom on
vertical surfaces. Let the foam act for up to 30 min-
utes for the optimal effect.
2. Proceed with cleaning using the high pressure
lance. Use applicable accessories. Use high pres-
sure to dislodge large amounts of incrusted dirt or
grime. Use lower pressure and high water volume in
order to rapidly flush away loose dirt and rinse sur-
faces.
3. Apply DES 3000 disinfectant once the surfaces are
perfectly clean.
Areas covered by amounts of loose dirt, such as ani-
mal remains in slaughterhouses, can be removed by
using high water flow to flush away the dirt to evacua-
tion pits or drains.
Tank cleaning heads can be used to clean barrels,
vats, mixing tanks etc. Cleaning heads may be hydrau-
lically or electrically powered and give the possibility for
automatic cleaning without a constant user.
Rusted or dam-
ages surfaces prior
to treatment
Wet Sandblasting
equipment 1. Connect the sandblasting lance to the pressure
washer and place the suction tube in the sand.
2. Always wear protective equipment during sandblast-
ing.
3. Spray the surfaces to be treated with the mix of wa-
ter and sand. Rust, paint etc will be stripped off.
These are merely several examples of cleaning tasks that can be solved by a pressure washer in asso-
ciation with accessories and detergents. Each cleaning task is different. Please consult your local dealer
or Nilfisk representative in order to discuss the best solution for your own cleaning tasks.

6.1 Switching off the
cleaner
1. Close water tap
2. Activate spray handle without
lance in order to empty all
residual water in the system.
3. Turn the ON/OFF switch to
position “OFF”.
4. Turn off the engine.
5. Activate spray handle until
the washer is depressurised.
6. Lock the safety catch on the
spray handle.
6.2 Storing / frost
protection
It is advisable to store the ma-
chine in a frost proof place be-
tween operations. If this is not
possible the machine should be
protected in the following way:
1. Disconnect the water inlet
hose. Remove the lance and
empty it of water.
2. Start the machine allowing it
to run with the spray handle
opened until it is empty of
water.
3. Place a suction hose in a
bucket with 6-8 l (1.5-2 gal-
lons) anti-freeze.
4. Place the spray handle (with-
out spray lance) above the
bucket, activate the spray
handle so that the anti-freeze
can circulate.
5. Place the psray handle above
the opening of the anti-freeze
container and allow the ma-
chine to pump all of the solu-
tion back into the anti-freeze
container. The anti-freeze can
be re-used, but keep in mind
that it is slightly diluted with
water each time this is done.
Important:
To avoid damage always ensure
that the washer, the hoses and
the spray lance are unfrozen
before restarting. Place the
washer and the accessories in
a warm environment for some
time before starting up.
