7-3) TRIAL STAGE
The “NEW” high pressure washer needs to pass a fast trial stage of the motor-pump group.
The trial stage consists in making the unit run for no longer than 1 hour and then wait for another 1 hour so it cools
down. This should be done 5 times.
7-4) INTERRUPTING THE RUNNING (TOTAL STOP)
The pressure washer model with total stop will stop running automatically when the trigger on the gun is released.
The pressure washer will restart as soon as the trigger on the gun is pressed..
WARNING
After the use of detergents or disinfectants it is useful to run the machine for a few minutes with clean water, to rinse
out the circuit.
WARNING
Do not use the pressure washer to suck in any products containing solvents, petrol, thinners, acetone, combustable oils,
toxic products or irritants because the vapours are highly inammable, explosive, toxic or irritant.
Read carefully the instructions and warnings recorded on the label on the detergent used.
WARNING:
Keep separate and clearly marked the tanks containing the diesel and the detergents. If one of the tanks is lled with
the wrong product, do not use the pressure cleaner and refer to a qualied technician or the retailer for advice
WARNING:
Remember that when the pressure washer is in total stop it is still in effect running.
Do not leave the machine unsupervised even for a short time, without having previously taken the following steps:
- press the power switch to the OFF position
- remove the plug from the wall socket
- close the tap of the water supply
press the trigger on the gun to discharge the residual pressure inside the hoses
