Attach the lance to the high-pressure hose (1) and the other end to the output connection (Water outlet).
Fit the sheath (B) in order to protect the hydraulic connection and to avoid the risk of scalding by contact.
The high pressure pump is supplied already full of lubricating oil. Attach a water tube (not supplied) to the
entry connection (Water inlet) and the other end to the tap of the water source (4) which must be able to
provide a minimum flow rate equal to that of the pump.
Check that the electric supply socket has the appropriate characteristics and differential protection, and
conforms to safety standards in force, then insert the plug into the power socket.
Wherever possible, avoid the use of extension cables with the electrical supply cable. If an electric
extension is required, please use the correct specification such as EXTENSION LEAD ' Motor Saver' - 30M
240VOLT 2.5mm (13AMP) - I10.1630
ATTENTION:
The electrical power supply should be provided by a magneto thermic switch adequate to the power of the
machine.
Also, there should always be installed a high sensitivity differential switch with a cut-off threshold of
Idn=0.030 A.
It is necessary that the machine is earthed in such a way as to guarantee a contact voltage of no more than
25V.
Operation of the machine should be carried out in such a way that damage cannot be caused to people or
property and, wherever possible, away from paths of transit.
In the United Kingdom, it is specified that an external socket (external to the building) must have an RCD.
This can be a ‘plug in’ IP rated 13amp RCD. If the External socket is 16amp than the RCD must be IP rated
and part of the socket.
RCD on internal sockets (which are part of the ring main electric supply), are normally on the main control
board and it is now specified that these are tested on the test button, at least every three months.
What is electric RCD?
An RCD, or residual current device, is a life-saving device which is designed to prevent you from getting a
fatal electric shock if you touch something live, such as a bare wire. ... RCDs offer a level of personal
protection that ordinary fuses and circuit-breakers cannot provide.

HOT WATER USE
Check that the diesel tank is full (Fuel filler); if it is not, refill it using exclusively automotive diesel or HVO
diesel which reduces carbon emissions by 80%.
For cold water operation, switch on only the (MACHINE ON–OFF) switch, and make sure the BURNER
ON-OFF is switched OFF.
Check that the thermostat (Burner Thermostat) is positioned at 0°C, start the boiler by means of the
appropriate switch (BURNER ON - OFF) which will cause the relevant light to illuminate, wait for 30 seconds
so that the diesel pump can refill, turn the knob of the thermostat (BURNER THERMOSTAT) to the required
temperature (upon reaching the desired temperature, the burner will cut off automatically to then restart
upon any lowering of temperature. Squeeze the pistol lever to obtain water flow to the lance, adjust the
pressure accordingly at the (PRESSURE ADJUSTMENT) control to suit the type of job and then start your
job.
To close down the machine, turn the thermostat (BURNER THERMOSTAT)) to zero, keep the pistol open (3)
and allow the water to cool, turn off the boiler (BURNER ON-OFF) turn off the water supply (2), turn off the
motor and pump (MACHINE ON-OFF), then squeeze the pistol lever until the residual water pressure has
been expelled.
STEAM OPERATION
Steam operation with the VSC is a wet steam operation. This means that although the water temperature is
100°C plus, you will still have water residue left when cleaning.
The advantage of wet steam over dry steam is that cleaning is a lot faster.
To achieve steam operation with the VSC there are certain very important settings that must be in place:
1. Turn the pressure adjustment knob on your V-TUF pressure washer to lowest pressure possible (
anti-clockwise – see below)
2. Switch on the burner switch (orange) and set the thermostat (round dial) setting on highest temperature
(clock-wise – see below)
Picture 1

13
Picture 2
Important points:
1. Run machine on this setting and you will notice the hot water will start steaming.
2. Proceed with cleaning.
3. Please note when the unit is very hot, the trigger can only be closed off for very short periods.
4. If you wish to take a break – you must turn the thermostat knob (picture 2) anti-clockwise to 0 degC and
run the water cool. Do this every time!
5.The coupling protection

bottom with overlapping strips until you reach the top of the area, sprinkling the whole are with
detergent. This system is known to avoid dripping of detergent onto dry surfaces, the residue of
which could remain even after rinsing.
In order to avoid the formation of deposits or crusts, at the end of operation it is advisable to pass
clean water through the pump for a few seconds.
Important Advice
To safeguard the environment, we advise that only authorised detergents are used, that the
recommendations of use and dosage are observed on the product labels, that detergent is used
sparingly and remember that use of inappropriate detergent, as well as damaging the environment
can damage the hot water cleaner as well as the objects being cleaned.
USE DETERGENTS WHICH ARE OVER 90%BIODEGRADEABLE.
Before sprinkling detergent over varnished areas with delicate colours, make sure that the surfaces
to be treated are not hot, that the detergent has not dried and that the concentration of water /
detergent is correct.
IMPORTANT: Rinse well.
Upon completion of operation, shut down the machine then squeeze the pistol lever until the residual
water pressure has been expelled.
LUBRICATION OF THE PUMP
For the models 100.12 and 150.15 we recommend:
PL500 Lube – OIL CAPACITY 0.42 kg
You should change the oil after the first 50 hours of use, and after each subsequent 500 hours of operation.
Repeat actions 1, 2 and 3 as per cold water use.
During operation, the detergent will be sucked up and automatically mixed with the water.
Practical Advice
Avoid soaking with water the surface you then wish to treat with detergent because, in doing so,
you can place a film of water over the area you wish to treat, resulting in poor cleaning results.
Instead, whilst holding the nozzle pointing towards the ground, wait until the detergent exits the
nozzle. When the detergent exits the nozzle, approach the surface you wish to treat, start from the
