2. with a garden hose (#13a+b): Your garden hose
requires a standard quick-coupler (not included in
delivery contents). Connect one end of the garden
hose directly to the main unit and the other to the
tap. Then turn on the tap. As soon as the tap is
opened, water comes out of the device. This is not
a defect, the device does not have a water start-
stop regulator. You can purchase a commercially
available regulator valve (not included in delivery
contents) for the garden hose or high-pressure
hose. Attach the regulator valve directly to the
device and connect your garden hose or high-
pressure hose to the this (#13b). Hold the main
device firmly and press the on/off button on the
handle. Keep the button pressed while using. As
soon as you release the button, the device switches
off. If necessary, turn off the water supply at the
regulating valve.

USING (#19)
Please follow the installation instructions to
assemble the high-pressure cleaner and get it ready
for use. After assembly, ensure that the flexible hose
with the nanofilter is submerged in water and that
the barrel and accessories are correctly assembled
and secured.
• To operate: Point the device at the floor and
press the on/off button on the handle to start
the pressure washer. The device must first be
primed to remove any pockets of trapped air in
the pump system. To remove any air build-up,
simply press the trigger while moving the hose
with the filter in the bucket of water at the same
time. It may take approximately 20 seconds for
water to be emitted from the cleaner. Once you
have a continuous flow of water, you are good to
go. Release the trigger to stop.
• To prevent an automatic switch-on of the device,
press the safety switch to the right. To unlock,
press the safety switch to the left.
