CS DUO:
Position 1 = Pump no. 1 in operation
Position 2 = Pump no. 2 in operation
Positions 1+2 = Pumps no. 1 and 2 in operation
Turn the main switch (2) to position 1, 2 or 1+2. Push the
green starting button (3).
Check on the pressure gauge (5) that a pressure is being
built up in the system. If a pressure is not being built up,
vent the machine as de scribed in section A.7 Venting.
B.3 Operation - automatic start/stop
Always hold the spray lance with both hands!
The machine is automatically activated when the trigger
(1) of the spray handle is activated.
When the trigger is released, the machine automatically
stops after 20 seconds.
When the machine is not in use, the trigger should be
locked with locking device (see arrow).
The spray lance features 2 nozzles, a high pressure
nozzle and a low pressure nozz le.
B.4 FlexoPowerPlus and PowerSpeedVario
- pressure regulation
Turn the outermost part of the FlexoPowerPlus spray
lance:
- High pressure = MAX
- Low pressure = MIN./CHEM.
B.5 Double spray lance, pressure regulation
The spray lance features 2 nozzles - a high pressure
nozzle and a low pressure nozzle.
High pressure mode
When the pressure reducing valve (1) is completely clo-
sed (turned clockwise - B), only the high pressure nozzle
is used - high pressure mode.
Low pressure mode
When the reducing valve (1) is completely opened (turned
counterclockwise - A), both spray lances are used - low
pressure mode / possibility of dosing detergents.
The pres sure may be reg u lat ed between these positions.
B.6 Stop
Danger of scalding!
Never detach high pressure hoses at a water temperature
above 50°C.
Never detach the high pressue hose while the machine is
in operation.
1. To stop the machine, push the red stop button (4) and
turn the main switch (2) to position - 0 -.
SC UNO 5M-L - switch main switch to position - 0 -.
2. Close the shut-off cock of the water inlet and activate
the spray handle or open the high pressure cock to
relieve the pipeline / high pressure hose of pressure.

B.7 Frost protection
The machine should be installed in a frost-free room. This
applies to pump as well as pipelines incl. of outlet points.
Concerning outdoor outlet points it should be possible to
empty that part of the line which is exposed to frost.
IMPORTANT: For safety reasons, hoses, spray lances
and other accessories should always be thawed prior to
use.
C - Maintenance
It applies to the most exposed components that a mini-
mum of maintenance ensures a prolonged and prob lem-
free operation. Therefore it will be a good idea to make a
habit of the following:
Prior to attaching the water hose and the high pressure
hose, the quick couplings should be cleaned of dust and
sand.
Prior to attaching the spray lance or other accessories to
the spray handle, the machine should be started and the
quick coupling cleaned of dust and sand.
C.1 Oil
Check the oil level in the oil glas.
If the oil level gets too low, the machine will automatically
shut down. The red button will fl ash (does not apply to
SC UNO 5M-L).
In the case of repeated low oil level (oil waste) please
contact a Nilfi sk service technician.
PROTECT THE ENVIRONMENT
Waste oil and oil sludge must be removed as laid down in
the instructions.
C.2 Water fi lter
To avoid debris entering the high pressure pump, a water
fi lter (fi ne) is fi tted at the wa ter inlet. Dependent on the
purity of the water, this fi l ter will have to be cleaned at
regular in ter vals.
The fi lter can be removed when the quick coupling (pos.
1) has been un screwed.
C.3 Cleaning of high pressure nozzle
A clogging up in the nozzle causes a pump pressure
which is too high, and a cleaning is immediately required.
1. Stop the cleaner and detach the spray lance.
2. Clean the nozzle.
IMPORTANT: ONLY use the cleaning tool when the
spray lance is detached.
3. Flush the spray lance backwards with water.
4. If the pressure is still too high, repeat items 1-3.
C.4 Disposable waste
This high pressure washer consists of parts which can
affect the invironment when thrown away. Parts that can
pollute are as follows:
Oil, painted/zinc-coated parts, plastics/plastic-coated
UNO/DUO BOOSTER
