Repeat points 1 and 2 as per cold water use.
Check that the thermostat (tr) is positioned at 0°C, start the boiler by means of the appropriate switch (br)
which will cause the relevant light to illuminate (b), wait for 30 seconds so that the diesel pump can refill,
turn the knob of the thermostat (tr) 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 (3) to obtain water flow to the lance, adjust the lance nozzle accordingly to control the outflow (4) and
then start your job.
To close down the machine, turn the thermostat (tr) to zero, keep the pistol open (3) and allow the water to
cool, turn off the boiler (br) turn off the water supply (2), turn off the motor and pump (in), then squeeze
the pistol lever (3) until the residual water pressure has been expelled.
ATTENTION:
In case of lack of diesel the burner will stop burning, either turn the burner off immediately or fill the fuel
tank back up with diesel.
ATTENTION:
This Machine is NOT equipped with a safety device to protect it from insufficient water supply. It is the
user’s responsibility to ensure that the water supply is consistent.
ATTENTION:
The machine is equipped with TS system which will stop the machine immediately after water pistol is
released. The machine will start up again once the pistol is pulled again.
ATTENTION:
Release pressure out of system once finished using the machine. This will prolong the life of the

USE WITH CHEMICAL PRODUCTS
With the machine shut down, act the device (adjustable head) placed on the lance end to obtain the suction
and the distribution of the product; pull the gun trigger to obtain the detergent distribution and start the
work.

13
ATTENTION
During operation of the machine, it is obligatory to use the appropriate personal safety equipment.
During operation, please pay close attention to the information quoted on the chemical product labels
regarding safety and the proper percentages to be used when diluting chemicals.
Fill the detergent tank (5) with the product you intend to use for your work and insert the detergent hose
suction.
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 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.

14
LUBRICATION OF THE PUMP
For the models 100.12 and 150.15 we recommend:

EVG= OFF (**)
BV= Off after 14 seconds (*)
MOT= Off after 14 seconds
S_TSI= On after 14 seconds
To restore the TSI system, it is necessary to verify the conditions of state 1 (pistol/lance open) followed by
state 2 etc…
The machine also manages the lack of fuel (PPG), 14 seconds after detection the EVG (**) and the BV (*)
will switch off. 1 second later the relevant warning light (S_GAS) will illuminate and the system will be
blocked.
To restore it, you must shut the machine down and turn it on again.
The machine is also supplied with a time-out feature so that if the machine is not used for 40 minutes, it
shuts itself down and the machine is blocked (shown by the TSI light illuminating). To restore normal
operation, it is necessary to turn the machine off and start it up again.
Finally , the machine is equipped with a particular algorithm for recognising water leaks so that if it should
detect 10 consecutive drips in less than 3 seconds, the machine will shut down and the TSI light will
illuminate. To restore operation it is necessary to turn the machine off and start it up again.
(**) EVG works only in hot water mode, with the water temperature thermostat.
(*) BV works only in hot water mode, independently of the water temperature thermostat.
