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 personal 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 first 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 ALTO
CONTRACTOR DIESEL machine itself.
3. Always switch off engine during work breaks.
4. Connect or disconnect the high pressure
hose ONLY when the engine is stopped.
5. Use only those hoses and nozzles
specified by ALTO.
6. The machine should only run for a
maximum of five minutes once the spray
handle has been released (the pump then
circulates the water internally and the
machine will overheat 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.
I
0
11. The machine must not be used in
surroundings with risk of fire 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 confined area.
13. To prevent fire 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 flammable 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
handle, cabinet.
1.1 Warning
Refilling with diesel:
Always stop the Ruggerini engine and allow it to
cool off for at least two minutes before filling with
diesel. Avoid spilling diesel. If diesel
nevertheless is spilled while refilling, 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 flame near the machine. It is forbidden to
smoke while refilling with diesel. Read the instruction 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 fibers into the
environment, 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 guidelines
and/or procedures.

2.0 Motor Protection Device 3.0 Key photo’s EN
The diesel engine is equipped with a protection
device called ”Oil Alert”, which stops the engine
if the oil level is insufficient. If this occurs, check
the engine for leaks, and after making sure the
machine is level, refill it to the proper level. The
engine can then be restarted.

4.0 Application EN 6.0 Accessories EN
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.
5.0 Standard equipment
The machine is delivered with a double lance
and a spray handle with high pressure steamcapable hose. The low pressure tube (pos. 30)
is fitted with a flat jet nozzle 6530* and the high
pressure tube (pos. 31) with a flat jet nozzle
1506*.
*) The first two digits of the nozzle number refer
to the spray angle, in degrees. The last two
digits indicate the water flow in l/min. at a pressure of 20 bar and a temperature of 20°C.
In order that you may make the most of your
high pressure washer, ALTO has produced a
very comprehensive accessory program,
including a pneumatic tire kit especially for the
CONTRACTOR DIESEL.
Please feel free to contact your ALTO supplier
for further information.
The actual nozzle orifice 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 ALTO hose. Use
only ALTO high pressure, steam-capable
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.
