D
Setting up the unit:
If your location is higher than 500 m (1625 ft) above sea level, your burner may require re-adjustment for proper performance and best fuel economy – Contact Nilfisk Service for assistance!
For location higher than 1000-2500 m might require an optional burner kit – Contact Nilfisk Service for assistance!
Before using the cleaner for the first time, check it carefully to detect any faults or damage. Run the machine only when it is in perfect condition.
D1. The slope on which the high pressure cleaner is placed must not exceed more than 10° in any direction.
OBS: ambient temperature should be above 0°C and not higher than 40°C.
D2. Set the brake.
D3. Fill up detergent tank 1).
D4. Fill up tank for Nilfisk AntiStone 1).
D5. Fill fuel tank with fresh fuel, heating oil, DIN 51603-1 (without bio diesel).

E12.c Suction from 25 L canister: (only for none hose reel version). Cut out the marked area with a knife to open the strapping points. Strap canister to the back of the machine. Pull out the hose (B) from the chassis and connect to canister.
E13. Using cleaning agents: Set the desired concentration of
(A) or (B) cleaning agent at the dosing knob 1) .
Spray the object. Allow the cleaning agent to work, depending on the degree of soiling. Then rinse off with the high pressure spray jet. Never allow cleaning agent to dry out on the object as the surface may be damaged.

F
After using the unit or before leaving it unattended
F1. Switch to cold mode.
F2. Run in cold mode to cool down product.
F3. Switch off the cleaner. Turn the switch to position „OFF“.
F4. Disconnect supply lines.
F5. Close water tap.
F6. Squeeze the spray gun to release pressure.
F7. Lock the safety catch on the spray gun.

G
G1. Storing the cleaner below 0°C:
Remove the water inlet hose from the cleaner. Remove the spray lance. Switch on the cleaner with the main switch in position “Cold Water”. Operate the spray gun.
Gradually pour antifreeze (approx. 5 liters) into the water tank (C). The machine is protected against frost when antifreeze solution emerges from the spray gun. Lock the safety catch on the spray gun. Switch off the cleaner. To avoid any risks, store the cleaner temporarily in a heated room before using it again. When the machine is put into service again, the antifreeze solution can be collected and stored for future use.
G2. Tilt and unscrew the filter glass 1) and empty it from water and fill it up with antifreeze and replace it on the cleaner again.

H
Maintenance & trouble shooting
H1.a Water inlet – Finger filter 1) : Unscrew quick coupling. Remove lock and filter and clean with water.
H1.b Water inlet – Large filter 1) : Tilt glas outward, unscrew glass and clean with water.
H2. Fuel filling filter: Filter can be removed by fingers and rinsed with clean fuel.
H3. Fuel filter: Open side door for access (A). Open hose clips and replace the fuel filter (B). Observe applicable disposal regulations. Contact Nilfisk for sparepart filter.
H4. Fuel Tank: Remove the drain plug and let the fuel pour into an empty container. Flush with clean fuel. Observe applicable disposal regulations.
H5. Pump oil: Check the pump oil quality: Check colour of pump oil. If the oil has a dark grey or white shade, contact Nilfisk service!
Top up cold pump with fresh oil to MAX if necessary.
H6. Flame sensor 1) : Remove the sensor and clean with a soft cloth. Ensure that the sensor is correctly seated when installing again – the symbols must face upwards.
