2.2 Safety devices on the machine
Circulation valve (safety valve)
The pressure side of the high pressure pump is fi tted with a circulation valve (safety valve). This valve cir cu lates the water back to the suction side of the pump when the spray handle is closed or if a nozzle is blocked. The circulation valve has been constructed as a safety function ensuring that the pres sure will never exceed the working pres sure by more than 25 bar. At this pres sure the circulation valve will au to mat ­i cal ly switch from high pressure to cir cu la tion mode. Never let the machine run for more than 5 min. upon release of the spray handle as it may be damaged. The valve has been adjusted and sealed from the factory. This adjustment must not be changed! The cir cu la tion valve ensures that the machine becomes devoid of pressure when it is stopped.
Motor protection
The engine will automatically stop if the oil level is insuffi cient. The engine can be restarted when having been re fi lled with oil.
2.3 General
1. It is not allowed to clean asbestos-containing surfaces with high pressure, unless using spe cial equip ment.
2. Persons under the infl uence of alcohol, drugs and medicine should not operate the machine.
3. When using detergents the enclosed in struc tions should always be strictly observed.
4. Don’t use the machine if important parts of the equipment are damaged - i.e. safety devices, high pres-
sure hoses, spray handle, cabinet.
5. WARNING! Battery acid contains corrosive sulphuric acid. Avoid contact with skin, eyes and clothes.
Even through your clothes the sulpuric acid may cause etching. If you get acid on your skin, fl ush with suffi cient water. If you get battery acid in your eyes, fl ush carefully with water for at least 15 minutes and send for a doctor.
6. WARNING! Battery acid is toxic. If battery acid is swallowed: Drink a lot of water or milk. Then more milk,
whipped eggs or vegetable oil and send for a doctor immediately.
7. The most effi cient cleaning is obtained if you adjust the distance to the surface which is to be cleaned.
Thus you will also avoid damaging the surface.

3.2 Starting-up procedure
Check oil
Turn the thermostat to the BLUE fi eld.
Turn to position “START”.
Check that the oil in the oil reservoir (2) is between the MIN and the MAX markings. Oil type: Nilfi sk-ALTO Pump Oil 100. Check the oil level on the Honda engine (5). Oil type: Choose oil type in accordance with the instructions in the Honda manual. Open the petrol cock (pos. 19) by pulling the control knob out. Activate the choke (pos. 20) if necessary by pulling the control knob out. Turn the temperature control (16) to the BLUE fi eld. Make sure that the high pres sure hose has been cor­ rect ly mounted. Start the Honda engine as described in the enclosed operating instructions. The key for the electric start has the following three positions: 1: O” off 2: I” run 3: “Start” - the key will return to position 2 when released Gradually push in the choke control if having been used.
3.3 Operation
33
Always hold the spray lance with both hands!
Always lock the spray handle when the cleaner is not in operation.
28
Activate the high pressure washer by releasing the trigger of the spray handle (28). When starting up the machine the pressure may be unsteady because of air in the pump system. After a short time the air will escape from the system and the pressure will become steady.
When the engine has been warmed up, check that the max. working pressure does NOT exceed the max­ i mum allowable pump pressure (see section "1.2 Technical data"). This can be taken from the pres sure gauge (pos. 21).
Do not let the machine run for more than 5 minutes once the spray handle has been released (the pump then circulates the water internally and the machine will overheat unless stopped after 5 min utes).
When the cleaner is not in use, secure the spray handle by turning the safety knob (33) into pos. 0.

3.4 Temperature control
Cold water mode 0 - 50°C Hot water mode 50 - 95°C Steam mode 95 - 150°C
Adjust the temperature control (16) to the required temperature. Indicator lamps on the temperature dis play (17) show the actual temperature of the outlet water.
Cold water mode: Upon the starting-up procedure the machine is immediately ready for cleaning with
cold water.
Hot water mode: Adjust the tem per a ture control (16) to the required tem per a ture, 30-95°C. Steam mode: Screw the valve for reg u la tion of the water volume (22) home (clock wise), and adjust
the temperature control (16) to the required tem per a ture, 95-150°C.
Note: The max temperature of 150°C can only be reached with the re duc tion valve
(27) of the spray lance ad just ed to high pressure (turn clockwise until stop).
IMPORTANT: When adjusting to tem per a tures above 95°C the valve for reg u la tion of the water volume (22) must be screwed completely home (clock wise) upon which the temperature control (16) can be
adjusted to the re quired tem per a ture, 95 - 150°C.
3.5 Spray lance, regulation of pressure and water volume
27
High pressure operation
The max working pressure of the ma chine is reached when the pressure reducing valve (7) is completely closed (B) and the valve for regulation of the water volume (22) is quite open (turned in the direction of the arrow). In this position only the high pressure nozzle is used - high pressure mode. The water volume is infi nitely variable between min and max output. When the spray handle is inactivated, screw the valve for regulation of the water volume (22) home (in the opposite direction of the arrow). This corresponds to a working pressure of 30 bar and a water volume of approximately 8 l/min. If you want to increase the water volume, turn the valve in the direction of the arrow until the re quired volume has been reached. 1 turn gives an increase of approx. 40 bar pressure.
Low pressure operation
If a completely reduced pressure is required, open the reduction valve (A) completely. The nozzle pres sure will then be approx. 5 bar. In this position both spray lances are used - low pressure mode.
Turn pressure reducing valve:
Clockwise (B): high pressure
Counter clockwise (A): low pressure
22
The spray lance features 2 nozzles; a high pressure nozzle and a low pressure nozzle.

3.6 Stop - dismounting of high pres su re hose
Danger of scalding!
Never dismount the high pressure hose when the water temperature is above 50°C.
If the machine is set aside immediately after hot water or steam operation, it should be cooled down in "cold water mode" at fi rst until the tem per a ture is below 50°C. Turn the temperature control (16) to the blue fi eld for cold water and activate the spray handle until the tem per a ture (17) is below 50°C. Then turn off the water supply and stop the Honda engine by turning the start/stop button (18) to position O. Close the petrol cock (pos. 19). (See instructions for the Honda engine). Now the high pressure hose can be dismounted.
3.7 Transport directions
15 15
For lifting by crane, use lifting straps!
When lifting the machine by forklift truck, be sure the forks extend completely under the machine to pre­ vent tipping. When lifting by tackle/crane a sling may be wrapped around the upper frame tubes (15) for lifting.
Ensure that no persons are under or near the machine when lifting it.
Always fasten the machine securely during transport.

Operating instructions EN
3.8 Storage - frost pro tec tion
Frost-free room or anti-freeze!
34
We recommend you to store the machine in a frost-free room between the cleaning tasks. The machine must be emptied of water prior to storing for a longer period. This is done in the following way:
1. Detach water hose. Dismount spray lance and empty it of water.
2. Turn the thermostat to the BLUE fi eld, start the machine, and let it run with activated spray handle until
all water has run out. Then empty the coil by unscrewing the drain plug (34).
FROST PROTECTION
If the store room is not frost-free, the ma chine should be protected with an an ti freeze. The frost protection is reached by following the two points above, screwing the drain plug in again and then do the following:
1. Place the inlet/suction hose in a bucket containing approx. 8 l anti-freeze.
2. Draw in the anti-freeze by activating the spray handle. Activate the spray handle 2-3 times while placing
it above the bucket with anti-freeze so that the anti-freeze can circulate.
3. Remove the inlet hose from the bucket, activate the spray handle and the rest of the anti-freeze is lead
back into the bucket.
NB! After repeated use the anti-freeze will be diluted with water and thus loose its anti-freeze effect.

4.0 Fields of application and work ing methods EN
4.1 Fields of application
The most important fi elds of application for this product are:
Transport Cleaning of trucks, buses, cars, engine rooms, etc. Building and construction Building renovation, cleaning/degreasing of ve hi cles, equipment,
Industry Degreasing and cleaning of machines, workpieces, and vehicles. Service Cleaning of vehicles and degreasing tasks.
4.2 Working pressure
The high pressure washer may be used with high or low pressure at your own option. At the standard spray lance the working pressure is adjusted by tur ning the reduction valve.
Low pressure Is fi rst and foremost used for application of detergents and for washing
High pressure Is used for cleaning. Intermediate pressure As an example it may be used for the cleaning of surfaces, which can-
4.3 Detergents
As standard the machine is delivered without a detergent injector. Detergent should not be added to the inlet water and thus pass through the pump. If you want to use de ter ­gents these should be added through an external injector (see accessories catalogue).
The most effi cient cleaning is obtained when using detergents in conjunction with high pressure cleaning. For that purpose Nilfi sk-ALTO can offer you a series of products specially developed for high pressure cleaning, e.g.:
buildings, etc.
off.
not stand a too powerful water jet, i.e. soft surfaces.
Cleaning of vehicles, machines, etc. Disinfection Degreasing of workpieces Maintenance of the high pres sure washer Descaling
The products are water-based, without phosphates, and the applied tensides (surface active substances) comply with the present requirements for easy biodegradability. Contact your Nilfi sk-ALTO distributor for directions as to which product(s) will fulfi ll your requirements. The method of application and the dosage of the individual products appear from the product labels or the data sheet. NOTE! Certain organic solvents are aggressive to rubber and plastics used in high pressure hoses and must therefore not be used. Using detergents outside the range from 4.0 - 10.0 pH will reduce the life of the equip ment.
Change from application of detergent under low pressure to cleaning under high pressure is simply ef­ fect ed by regulating from “low pressure mode” to "high pressure mode" on the spray lance. For foam cleaning mount the special foam injector between the high pressure washer and the high pres­ sure hose. Insert the suction hose of the injector into the foam detergent. Attach the foam lance to the spray handle and now foam can be applied. Upon application detach the foam injector and replace the foam lance by a spray lance and you are ready for cleaning.

Fields of application and working methods EN
4.4 Working methods
Your high pressure washer has been developed for cleaning according to the so-called "2-step method".
STEP 1 Application of detergent STEP 2 High pressure cleaning
In practice the working process is laid down in accordance with the actual job, but as a starting point the fol low ing working method can be described for a job:
1. Apply detergent under low pressure. The dosage is chosen according to the job which is to be
carried out, and the adjustment is made on the control knob on the injector.
2. Await acting time. Let the detergent act on the dirt/surface for a short time prior to pressure clean ing
- usually a few minutes.
3. High pressure cleaning. Clean all surfaces under high pressure.
4. Rinse afterwards, if necessary. To make sure that residual impurities are removed from the sur face.
In connection with the working process the optimum cleaning will be reached by following these 3 pieces of advice:
Advice no. 1
When using a detergent, always apply it on a dry surface. If the surface is rinsed with water at fi rst, it may be diffi cult for it to absorb the detergent, and the result is a reduced effect of the detergent.
Advice no. 2
When applying a detergent on large vertical surfaces (i.e. the sides of a truck) work from below and up­ wards. Thus you will avoid detergent running off the surface through grooves and dark streaks appearing on the surface whilst cleaning.
Advice no. 3
During the high pressure cleaning you should work so that the high pressure water does not run over the surface which has not been cleaned yet. This is to ensure that there is suffi cient detergent on the surface when the high pressure water hits the surface.
For certain cleaning tasks it may be an advantage to apply detergents for high pressure operation - i.e. for the dewaxing of cars.
5.0 Pre-priming
The pressure washer is self-priming, and the water can be taken from a tank, a stream or the like. The suc tion height depends on the water temperature. Max. suction height of 5 m is reached with cold water up to 12°C. The pump and the inlet hose must be primed with water before starting up. If there is a risk of impurities (such as running sand) in the Intel water, an external fi lter must be mounted beyond the internal fi lter. Please contact your Nilfi sk-ALTO distributor for further in for ma ti on.

6.0 Functional description EN
6.1 General description
The water passes from the quick coupling (a) through a water fi lter (b) into the high pressure pump (c). The high pressure water leads through the discharge system of the pump where the safety and circulation valve (d) is situated. Then it passes the fi rst fl ow switch (e) to the non-return valve with throttle (f), through the second fl ow switch (g) and en ters the boiler (h). Here the water is heat ed to the required tempera­ture. After the boiler the hot high pressure water pass es the tem per a ture sensor (i), through the outlet quick connector (j) to the spray han dle (k) and the spray lance (l). The fuel is drawn from the fuel tank (m) through the fuel fi lter (n) by the fuel pump (o). Now the pump leads fuel through the solenoid valve (p) to the noz zle (q) where it is ig nit ed. The combustion in the boiler is monitored by the fl ame sensor (w) and is supplied with air from the fan (r) which together with the high pressure pump (c) are driven by the petrol engine (s).
6.2 High pressure pump
On the pressure side the high pressure pump features a circulation valve (d). This valve leads the water back to the suction side of the pump when the spray handle is closed or if a nozzle is blocked. The circula­tion valve also functions as a safety valve and has been adjusted to open approx. 25 bar above the work­ ing pressure. The valve has been adjusted and sealed from the factory. This adjustment must NOT be changed! When the machine stops it is automatically devoid of pressure.
6.3 Petrol engine
A description of the operation/maintenance instructions for the Honda engine will be found in the Honda manual provided with the machine. Please read this before starting up. The throttle limit of the engine has been adjusted by Nilfi sk-ALTO so that the max. number of revolutions corresponds to the max. pressure of the pump (see section "1.2 Technical data"). The adjustment is sealed and must NOT be changed.
6.4 Burner system - control system
The burner system is surveyed and controlled by an electronic control unit which includes a thermostat, fl ow switches to control the water fl ow and a sensor to monitor the fl ame.
The water temperature is controlled by the temperature sensor (i) which regulates the fuel supply for the burner through the solenoid valve (p). As the burner is only allowed to operate when there is a water fl ow in the system (i.e. when the spray handle is activated) the machine features two fl ow controls (e-g) which con trol the fuel supply through the electronic control unit. When the fl ow in the system is interrupted, the fl ow switch es are activated and the fuel supply will stop. When the water fl ow repeats, the fl ow switches are re ac ti vat ed and reallow the fuel supply. Safety circuits in the electronic control unit survey that both fl ow switch es are activated. Thus the fuel supply is interrupted when only one of the fl ow switches are activated. When the water fl ow is repeated the control unit only allows the fuel supply if both fl ow switches have been activated. The fl ame sensor is a separate circuit stopping the machine if there is no fl ame in the burner in hot water or steam mode. It is important for the life of the fuel pump that the machine is not allowed to run in the hot water or cold water mode with empty fuel tank. If the burner stops working unexpectedly, check the fuel level in the tank and refi ll if necessary. NB! Changes of the electrical coupling of the machine are not allowed.

The following sensors are built into the system:
- Flow switches (e-g)
Ensure that there is a water fl ow through the boiler, before it can be ignited. Allows the solenoid valve (p) to open.
- Flame sensor (light sensor) (w)
Surveys that there is a combustion in the boiler when fed with fuel, and that the combustion will stop
when the fuel supply is cut off.
- Temperature sensor (i)
Measures the temperature of the high pressure water from the boiler. Dependent on higher or lower
tem per a ture the burner will ignite or turn out.

7.0 Maintenance EN
7.1 General
To ensure that your Nilfi sk-ALTO high pressure washer is always in an operational condition it is advisable to have it checked by a Nilfi sk-ALTO service technician at regular intervals. However, it applies to the most exposed components that a minimum of maintenance ensures a pro longed and problem-free operation. Therefore it will also be a good idea to make a habit of the following:
z Before mounting the water hose and the high pressure hose the quick couplings should be
cleaned of dust and sand.
z Before mounting spray lance or any other accessory on the spray handle, the machine should
be started and the quick coupling cleaned of dust and sand.
z The water fi lter should be cleaned once a month or more frequently as the occasion requires. z We recommend you to store the machine in a frost-free room. If by mistake the machine
freezes up, it must not be started. Let machine, hoses and accessories thaw up before starting
up. If the room is not frost-free the machine should be protected with an antifreeze. z Replace fuel fi lter (14) once the year or more frequently as the occasion requires.
7.2 Oil
Oil change - pump
The oil shold be changed after each 1000 hours’ use. Remove the cover of the oil reservoir (2). Unscrew the drain plug (3). Allow the oil to run out and clean the drain plug of impurities. Screw in the plug and refi ll the pump with fresh oil through the oil reservoir. Holds approx. 1 l. From Nilfi sk-ALTO the pump is fi lled with zincless hydraulic oil - Nilfi sk-ALTO Pump Oil 100. When refi lling and chang ing the oil this or an oil with the following specifi cations should be used: ISO no 100 Viscosity index (VI) min 130 Pour point below -30°C
Sludge container
The used oil is caught in a sludge container (4). The container should be emptied before it is full; this oil must not be reused in the pump.
Oil change - Honda engine
Refer to the Honda engine manual for maintenance and oil change requirements. Carry out fi rst oil change after 20 hours’ operation and then every 100 hours. Not less than once every six months, how ev er.
PROTECT THE ENVIRONMENT
Waste oil and oil sludge must be removed as laid down in the instructions.
7.3 Water fi lter
To avoid debris entering the high pressure pump, a water fi lter is fi tted at the water inlet (1). Dependent on the purity of the water this fi lter will have to be cleaned once the month or more frequently as the oc ca sion re quires. The fi lter can be removed when the quick coupling has been unscrewed.
7.4 Fuel fi lter
A fi lter (14) between the fuel tank and the fuel pump prevents impurities from penetrating the fuel pump. The fi lter unit should be changed dependent on the purity of the fuel. A yearly change of the fi lter is rec om ­mend ed.

Maintenance EN
7.5 Descaling of coil
After a period of operation depending on the hardness of the water scale deposits will begin to ac cu mu late in the heating coil. These deposits will reduce the effect of the water heating system and increase the fuel consumption. The machine should therefore be descaled regularly. If the machine adjusted on max. water volume will not heat cold water (8°C) to 70°C within three minutes, the burner or the coil requires servicing or descaling.
Descaling as follows:
1. Detach high pressure hose.
2. Insert the inlet hose in a container with descaler, Nilfi sk-ALTO Stonex and water in the ratio 1:10.
3. Start the machine in cold water mode.
4. Stop the machine when the water escaping the outlet socket has been coloured by the descaler. Warning: The mixture may be caustic! Do not on any occasion empty the container to prevent air getting into the system.
5. Let the machine rest for 20 minutes.
6. Start the machine and pump the used solution into a container for proper disposal.
7. Immediately attach the water inlet hose to the water supply and turn on the tap.
8. Start the machine and let it run 5 - 10 minutes to have the descaler out of the system.
9. If required, repeat the procedure from item 3 - 8. Note! The descaling should always be carried through in ac cord ance with the instructions on the descaler product.
7.6 Cleaning of high pressure no zz le
A clogging up in the nozzle causes a pump pressure which is too high and cleaning is im me di ate ly re­ quired.
1. Stop the cleaner and detach the spray lance.
2. Carefully clean the nozzle. IMPORTANT: ONLY use the cleaning tool when the spray lance is de tached!
3. Flush the spray lance backwards with water.
4. If the pressure is still too high, repeat items 1 - 3.
