1.0 Safety EN

Your CONTRACTOR DIESEL washer has been
developed and manufactured in accordance with
the latest working safety regulations.
Caution! However, to prevent possible per so nal
accidents or damage to any other product, we
advise you to read carefully through this section
on safety precautions before you operate your
washer for the fi rst time.
General safety precautions
1. Always use both hands for operating spray
equipment to maintain complete control of
the lance.
2. Water jets should never be directed towards
people, pets, electrical wiring or the Nilfi skALTO CONTRACTOR DIESEL machine itself.
3. Always switch off engine during work breaks.
11. The machine must not be used in surroundings with risk of fi re or explosion.
12. Exhaust from engine and burner contains
poisonous carbon monoxide gases. Avoid
inhalation of exhaust gases. Never run the
machine in a closed garage or confi ned area.
13. To prevent fi re hazards and to provide adequate ventilation, keep the engine at least
1m/3ft away from buildings and other equipment during operation.
14. Do not place fl ammable objects such as
gasoline, matches, etc., close to the machine
while it is running.
15. Allow only properly instructed personnel to
use the machine.
16. Never let children operate your CONTRACTOR DIESEL at any time.
17. Don’t use the machine if important parts of
the equipment are damaged - i.e. safety
devices, high pressure hoses, spray hand le,
cabinet.
4. Connect or disconnect the high pressure
hose ONLY when the engine is stopped.
5. Use only those hoses and nozzles specifi ed
by Nilfi sk-ALTO.
6. The machine should only run for a maximum
of fi ve minutes once the spray handle has
been released (the pump then circulates the
water internally and the machine will over heat unless stopped after 5 minutes).
7. The pump is equipped with a high pressure
relief safety valve. This adjustment, like any
others that require the use of tools, should
only be made by a trained service technician.
8. Operating the machine when it, or any attachments are frozen, is dangerous. Be sure
everything is thawed before operating the
machine.
9. Manufacturer’s instructions for the use of any
detergents should be carefully observed at
all times.
10. During work breaks, or any time lances or
accessories are changed, the spray handle
must be secured by rotating the safety knob
into position O.
1.1 Warning
Refi lling with diesel:
Always stop the Ruggerini engine and allow it to
cool off for at least two minutes before fi lling with
diesel. Avoid spilling diesel. If diesel nevertheless
is spilled while refi lling, the engine must not be
started before the spilled diesel has been removed. If the machine is located in a trailer, any
diesel spillage must be removed before restarting
the machine. Never use an open fl ame near the
machine. It is forbidden to smoke while refi lling
with diesel. Read the in struc tion manual for the
Ruggerini engine carefully.
NOTE: Never run the machine in a closed room.
The exhaust gases are dangerous
1.2 Asbestos
To avoid release of asbestos fi bers into the environment, Nilfi sk-ALTO strongly recommends that
this machine not be used for cleaning of materials or surfaces of materials containing asbestos.
If this machine is to be used for asbestos removal
do so only in complete compliance with approved
goverment guide li nes and/or procedures.

2.0 Motor Protection De vice
The diesel engine is equipped with a protection
device called ”Oil Alert”, which stops the engine
if the oil level is insuffi cient. If this occurs, check
the engine for leaks, and after making sure the
machine is level, refi ll it to the proper level. The
engine can then be restarted.

4.0 Application EN 6.0 Accessories EN
Nilfi sk-ALTO’s diesel powered high pressure
washers can be used for all outdoor cleaning
jobs for which steam, hot or cold water is used.
Detergents can be used (see section 8.5)
4.1 Handling and Transport
When handling the machine with a fork lift truck,
be sure the forks extend completely under the
machine to prevent tipping. When lifting the
machine, a sling may be wrapped around the
upper frame tubes for lifting. Ensure that personnel aren’t under or near the machine during
lifting. When transporting the machine in a truck
or trailer, be sure that it is secured against sliding
or tipping.
In order that you may make the most of your high
pressure washer, Nilfi sk-ALTO has produced a
very comprehensive accessory program, including a pneumatic tire kit especially for the CONTRACTOR DIESEL.
Please feel free to contact your Nilfi sk-ALTO supplier for further information.
5.0 Standard equipment
The mac hi ne is delivered with a dou ble lance
and a spray handle with high pres su re steamcapable hose. The low pressure tube (pos. 30)
is fi tted with a fl at jet nozzle 6530* and the high
pres su re tube (pos. 31) with a fl at jet nozzle
1506*.
*) The fi rst two digits of the nozzle number refer
to the spray angle, in degrees. The last two digits
indicate the water fl ow in l/min. at a pres su re of
20 bar and a temperature of 20°C.
The actual nozzle orifi ce size are 0.63” (1.6 mm)
for the nozzle 1506 and 0.142” (3.6 mm) for the
nozzle 6530. NEVER replace the nozzles with
those of a smaller size.
Maximum working pressure and temperature
rating are embossed on the Nilfi sk-ALTO hose.
Use only Nilfi sk-ALTO high pressure, steamcapable hoses. In case of damage to your hose,
DO NOT attempt to repair the hose yourself! The
thrust (backwards turned force) on the nozzle is
approximately 12.5 ft/Ib (55 N).
Since the nozzles are mounted at an angle to the
lance, there will be a torque effect at the handle
when spraying. Always use two hands when
operating the spray equipment.
