Setting up the unit:
Setting up the pressure washer
• Before using the pressure washer for the first time,
check it carefully to detect any faults or damage
• In the event of any damage contact your Nilfisk dealer
immediately.
B1 • Check whether the oil level is in the middle of the oil
B2 inspection glass, oil cup or dip stick. This also applies to
B3 machines with gear. (MC 7P does not have oil dip stick).
(MC 2C does not have inspection or dip stick).

Switching on the unit:
Connections:
Connecting the lance to the spray gun
C1 1 Pull the blue quick-release grip (A) of the spray handle
backwards.
2 Insert the nipple of the spray lance (B) into the quick-
release connection and release it.
3 Pull forward the spray lance or any other accessory to
ensure correct mounting before starting the machine.
NOTE! Always remove any dirt from the nipple before
connecting the lanse to the spray gun.
Connecting the high pressure hose and the water hose
C2 1 Connect the high pressure hose to the high pressure
C3 inlet by means of the quick coupling. Use max. 50 m
C4 extension hose.
C5 2 Before connecting the water hose to the washer, rinse
the water hose briefly to prevent sand and other dirt
from entering into the washer.
3 Open the tap.
NOTE! See chapter “specifications” for required quantity
of water and water pressure. In the case of poor water
quality (sand, etc.), we recommend that a fine water
filter is fitted in the water inlet.
FUELLING:
• IMPORTANT! Always shut off the engine and let it cool
for at least two minutes before fuelling. Avoid spilling
fuel. If you do spill fuel when fuelling, do not start the
engine before the spilled fuel has evaporated. If the
washer is on a trailer, any fuel spills must be wiped up
before the machine is started.
Never expose the machine to an open flame.
Smoking is prohibited during fuelling. Also read the
operating manual for the fuel engine. Never operate the
machine in a closed room; the exhaust fumes are
dangerous. Follow the safety instructions!
Start the washer:
Switching on the washer when it is connected to a water
supply
C6 1 Start the engine. (See the operating manual for the fuel
engine.)
2 Unlock the spray gun and activate it.
3 Lock the safety catch even during short pauses.
NOTE! Activate the spray gun several times at short
intervals to vent the system.
If it requires too much power to start the engine, it can
be facilitated by removing the spray lance and activate
the spray gun during startup.
Switching on the washer when it is connected to open tanks
(suction mode)
C7 1 Before connecting the suction hose to the washer, fill
the hose with water.
2 Start the washer.
3 Unlock the spray gun and activate it.
4 When using this machine in suction mode, first
ensure that the system has been bled of air by letting
the machine run without high pressure hose and spray
lance mounted until all air has escaped. On some
models you need to kink the by-pass hose and / or
move the engine throttle to minimum position to achieve
enough suction power.
• During work breaks of more than three minutes, switch
off the washer.
NOTE!
For automatic suction from a tank,
watercourse or similar supply, the inlet hose must
be filled with water before you start. The suction
height depends on the water temperature. Max.
suction height is reached with cold water (up to
8°C). With 60°C warm water, the machine must be
under or at the water level.
If the water being suctioned contains particles, a suction
