4.0 Standard equipment
The cleaner is delivered with a double lance and
a spray handle together with high pressure hose
as standard equipment. The low pressure tube is
equipped with a fl at jet nozzle 6530 and the high
pressure hose with a fl at jet nozzle 1506.
The fi rst two fi gures of the nozzle reference
number indicate the spray angle in degrees and
the last two indicate the water fl ow in I/min. at a
pressure of 20 bar and a tem per a ture of 20°C.
The equivalent hole diameters for nozzle 1506 is
1.6 mm and for nozzle 6530 is 3.6 mm. Do not
replace with nozzles of a smaller diameter. The
maximum working pressure and temperature
are printed on the standard high pressure hose.
Only use Nilfi sk-ALTO high pressure hoses. In
case of damage, arrange for Nilfi sk-ALTO service
engineers to repair it. Do not attempt to repair it
yourself.
The thrust on the nozzle is for:
4403KOS 47N
As the thrust forms an angle with the spray lance,
the spray handle is subject to torque.

5.0 Operation
5.1 Starting-up procedure
1. Check the oil level in the oil glass. The level
should be maintained between the MIN. and
MAX. marks.
2. Run water through the inlet hose before connec-
ting, in order to remove possible impurities in the
hose. Connect the hose.
3. Connect the quick coupling (a) of the high pres-
sure hose to the outlet socket.
4. Check the input end of the spray lance (b) for
possible impurities. Pull forward the grey trigger
(c) of the spray handle. Connect the input end of
the spray lance to the quick coupling. Release
the grey trigger.
5. Press the trigger of the spray handle (d) and
allow the water to run, until the system has
been completely vented. For self-priming it is
recommended to open the regulating valve (e)
during the venting.
6. Release the trigger of the spray handle (d) and
turn on the hydraulic supply. The pump will now
be in idle motion.
7. For cleaning at high pressure press home the
trigger of the spray handle after having closed
the regulating valve.
8. For cleaning at low pressure open the regulating
valve.
5.2 Stopping
1. Turn off the hydraulic supply.
2. Turn off the water supply and disconnect the
hoses.
3. Do not disconnect the high pressure hose, until
the cleaner has cooled down and stopped.
