4. USE
a. Before starting the machine
NOTE: Never operate the machine without first opening the water supply!
Never open the sprayer cover during operation. Do not use the sprayer in hazardous
environments and
Do not put water in materials containing asbestos and other materials hazardous to
health
Do not use liquids containing organic solvents, acids or solvents based on petroleum,
paint or oil whose vapors are highly flammable, explosive and toxic. The acetone
compounds, solvent acids are corrosive and can damage the device.
Open the faucet but do not start the machine immediately.
Press the gun trigger until the air has been expelled from the sprayer and the water
begins to flow. As soon as the water begins to flow at the tip, release the trigger. The
sprayer is now primed. You can now turn on the unit.
b. Start/Stop
Turn the power switch to ON.
Press and hold the gun trigger to start work.
Release the trigger to temporarily stop working, and then press the trigger again to restart.
Keep an adequate distance from the workpiece.
To work further, unwind the hose using the unwinder handle.
If you must stop using the device for more than 2 minutes, please turn it off.
At the end of the operation, release the trigger.
Switch off the machine by turning the power switch to OFF and unplug the power plug.
Press gun trigger to remove pressure.
NOTE: The trigger gun features a locking device. When the knob is activated, the
trigger gun cannot be operated.
c. Use with detergent
Note: Make sure the machine is turned off before putting detergent.
Open the cap and pour detergent into the container. Then install the detergent bottle to
the extension gun (as explained in Assembly section).
Detergents can be bought in gardening shops and on the Internet.
The use of detergent can reduce working time and help to remove stubborn dirt. Some
detergents are specially designed for use with high-pressure cleaners for specific
cleaning tasks. The viscosity of these detergents is close to that of water. If detergents
with a higher viscosity are used, such as detergent, the detergent injection system will
clog and you will not be able to spray the detergent.
Detergents can only clean a surface if they are applied to the surface long enough so that
their chemicals can degrade dirt and grime. They are more effective if applied at low
pressure.
The combination of the action of chemical agents and a high pressure rinse is very
effective in removing dirt. On the vertical surfaces, apply detergent starting at the bottom
as you move upwards. This will prevent the detergent from flowing downwards by forming
trails. Similarly, you must rinse the bottom surface up.
