If the machine is to be operated
at fuel stations or in other
potentially hazardous areas, the
machine may only be employed
outside the hazard areas defined
in the "Technical Guidelines for
Inflammable Fluids" applicable at
the point of use due to the
potential explosion hazard posed
by the burner.
If the machine is to be operated
indoors, the local building
regulations must be observed for
the discharge of the exhaust
fumes into the atmosphere.
Ensure an adequate supply of
fresh air.
If the machine is to be connected
to a flue gas stack, the state
building regulations must be
observed. We will be glad to
provide tips for connection
systems, on request.
The machine must be supervised
at all times so that the operator
can notice when the flame goes
out.
ð Secure the machine with
the parking brake (Fig. 2).
ð Check the oil level in the
high-pressure pump (Fig. 3).
ð Fill the cleaning agent tank
with prediluted Alto cleaning
agent.
ð With the machine cold:
Pour fuel (fuel oil EL, biodiesel
E to DIN 51 606 or diesel fuel
to DIN 51 603) into the fuel
tank.
The fuel must be free from
contamination.

Unsuitable fuels must not be
used as they can represent a
source of danger.
At temperatures below 8° C,
+
the fuel oil begins to solidify
(paraffin precipitation). This
can lead to difficulties in
starting the burner. Before the
winter period either add a
solidification point / flow
improver (available from the
fuel oil trade) to the fuel or
use winter diesel fuel.
ð Fill the tank for the Alto
automatic scale alarm system.
"Alto Anti-Stone" prevents any
deposits of scale and acts at
the same time as a corrosion
inhibitor. Use the bottle
supplied with the pack for
filling (Fig. 4). For compatibili-
ty reasons, use only the tested
"Alto Anti-Stone". Order the
refill pack 6 x 1000 ml, No.
8466, in good time.
ð Screw the high-pressure hose
firmly onto the VarioPress
trigger gun1), pushing back the
slide of the locking pin (Fig. 5/
1 + 5/2).
ð Securely tighten the screw of
the Roto-Fix high-pressure
spray lance, at the same time
pushing back the slide of the
locking pin (Fig. 5/3 + 5/4).
ð Connect the water hose (Fig. 6).
The use of a fabric-reinforced
water hose with a nominal
diameter of at least 1/2" (13
mm) is recommended.
ð Connect the high-pressure
hose to the high-pressure
connection. Ensure that the
union nut is securely tightened
(Fig. 7)!
ð Turn on the water tap.
ð Insert the plug of the cleaner
into the plug socket.
STARTING OPERATION
RTING OPERATION
The pipework of the machine
+
is filled with antifreeze.
Collect the first liquid (approx.
5 litres) which comes out of
the spray gun in a suitable
vessel for further use.
COLD WATER OPERATION
ð Release the lock of the trigger
gun and press the trigger (Fig.8).
ð Turn the operating mode
switch to position .
-> The function test of the
displays on the operating
panel starts.
– All the indicator lights
come on briefly, then the
indicator light
comes on
continuously to indicate
that the machine is ready
for operation.
ð Operate the trigger of the
trigger gun several times at
short intervals to bleed the
system.
HOT WATER OPERATION
ð Select the temperature (20-
100° C).
ð Release the lock of the trigger
gun and press the trigger (Fig.8).
ð Turn the operating mode
switch to position .
ð When a steady jet emerges
from the high-pressure nozzle,
turn the operating mode
switch to position .
Using a special device1), the
condensate coming out of the
heat exchanger can be collected
and disposed of in accordance
with the local sewage regulations; water poured in and emerging at the nozzle then has the
same composition.
STEAM OPERATION
(OVER 100° C)
1)
Replace the standard highpressure nozzle with the steam
spray nozzle (No. 6692)1). Set the
thermostat to a temperature of
above 100° C. Turn the rotary
knob on the safety control block
completely to the left (anticlockwise direction) (Fig. 9). Release
the lock of the trigger gun and
press the trigger. Turn the operating mode switch to position

lance allows the spray lance to
be turned for pressure-free
operation:
ð Push back the slide of the
locking pin (Fig. 5).
ð Turn the screw fitting of the
RotoFix high-pressure spray
lance until the pin engages in
the next bore.

to position .
ð Allow the machine to run for
approx. 1 minute, then turn the
operating mode switch to
position OFF.
ð Actuate the trigger gun until the
machine is completely depressurised.
ð Insert the safety lock (Fig. 8/1).
ð Turn off the water tap.
ð Pull the machine plug out of the
plug socket and coil up the
mains cable.
ð Disconnect the water hose from
the machine.
ð Store the machine in a frost-
proof room where it is safe from
unauthorised use.
If the machine cannot be stored in a
frost-proof room, proceed as follows:
ð Turn off the water tap.
ð Turn the operating mode switch
to position and actuate
the trigger gun
ð Gradually pour antifreeze
(approx. 5 litres) into the water
tank.

frost when antifreeze solution
emerges from the nozzle of the
spray lance.
ð When the machine is put into
service again, the antifreeze
solution can be collected and
stored for future use.

DESCALING
Descaling agents cause burns.
Avoid contact with the skin,
eyes and clothes. Wear appropriate protective clothing (e.g.
gloves, face mask, apron).
Only approved scale removers
may be used for descaling.
Use Alto Stone-EX, No. 81236
With regular use of Alto
+
Anti-Stone, descaling will
normally not be necessary.
Incorrect operation of the machine or the use of non-approved
cleaning agents can cause
deposits in the pipework system.
Scaling is caused by the water
hardness and is indicated by a
gradual increase in the water
pressure displayed on the pressure gauge.
If the working pressure is exceeded by 10 bar (with the VarioPress trigger gun open), the
system must be descaled.
Procedure:
ð Unscrew the high-pressure
nozzle from the spray lance
and place separately in the
Alto scale remover.
ð Draw in Alto scale remover
via the metering valve by
hanging a cleaning agent
hose into the scale remover
bottle and setting the metering valve to maximum
concentration.
ð Hold the spray lance in a
separate container to collect
the discharged liquid.
ð Switch on the high-pressure
pump.
ð Actuate the trigger gun. Alto
scale remover is drawn in and
emerges from the spray lance
foaming vigorously after
approx. 1 minute.
ð Switch off the high-pressure
pump and allow the scale
remover to work for approx.
15 minutes.
ð Flush out the pump system
well with clean water.
ð After approx. 2 minutes, a
steady jet of water must
emerge at the water outlet
tube. If this is not the case,
repeat the descaling procedure.
ð Screw the high-pressure
nozzle onto the spray lance.
FROST PROTECTION
If the high-pressure cleaner is
stored in a room in which temperatures of below 0° C can occur,
antifreeze must first be flushed
through the pump.
During the flushing process,
actuate the trigger gun 2 or 3
times.
In order to avoid any risk, the
machine should preferably be
stored for a short period in a
heated room before it is put into
service again.
