5. Use of device
Charging station and rechargeable battery
The device is partially assembled already in the production process. Additional parts
must be assembled according to the instructions. It is necessary to read the safety
instructions rst:
• The mains voltage must correspond to the specication of the charging station.
• Only the supplied charger may be used to charge the battery. The device must be
charged in a dry place. It is only possible to charge the battery when the temperature
of the battery is within the temperature range 0-45 °C.
• The battery is partially pre-charged. The battery must be fully charged before rst
use.
• While charging the battery, the charging station and the battery may heat up. This is
normal and does not cause a malfunction. The battery can be charged at any time,
regardless of the state of discharge. Charging with a fully discharged battery does
not affect the efciency and life of lithium-ion batteries.
• Signicantly shorter operating time after charging means that the battery is worn out
and needs to be replaced. After repeated use, this is normal and expected.
• Decreased efciency (charge status) of the battery over its lifetime is normal. The
battery can only be replaced with an original battery purchased from an authorized
dealer.
• The battery has three charge indicators. When all three indicators are green, the
battery is fully charged, and when only one indicator is flashing, the battery is nearly
empty. The display of the indicators is shown in Photo 4.
Photo 4: Display of full battery charge without waterproof protection (left) and with waterproof protection (right)

10
• The empty battery is connected to the charging station for charging. The charging
station has an indicator on its bottom right side that flashes green while the
battery is charging. When fully charged, it stops flashing and only glows green, which
means that charging is complete. The rechargeable battery can be removed and used
at any time during charging.
• The charging station has another indicator at the bottom left that warns the
user in case of incorrect charging of the battery. If the indicator is ON continuously,
the battery temperature is outside the allowable temperature range. When the
allowable temperature range is reached, charging starts and the indicator turns off.
If this indicator flashes, an error occurred while charging. This may be due to a fault
in the battery or charging station. In this case, the user should remove the battery
from the charging station and clean the battery contacts with a dry cloth. If the
indicator still flashes, seek professional help or purchase a new set of battery and /
or charger.
Correct placing of the battery from the device to the charging station and vice versa is
shown in Photo 5.
The contacts must be dry and clean when placing and removing the battery on the
cordless pressure sprayer or charging station. After placing the battery on the cordless
pressure sprayer, it is necessary to place the included elastic waterproof protection over
the battery to protect it from water intrusion. It is forbidden to use the device without
the protection. It is recommended to remove the battery from the battery pressure
sprayer after its use, as removing the battery helps to prolong the life of the battery. The
procedure for removing waterproof protection is shown in Photo 6.

the battery. The waterproof protection must not be stretched, as you can destroy it
this way. The method of placing the waterproof protection when removing the battery
and when using the device is shown in Photo 6.
• The basic package comes with a universal nozzle (already installed on the device). In
the case of cleaning or replacement, the nozzle can be removed manually by turning
the nozzle by 90° and pulling. The method of removing the nozzle is shown in Photo 7.
• Once the battery is installed, the cleaning gun is activated by the release button.
Above the release button there is a lock button that locks the release button during
the operating mode so that the user does not have to hold it constantly.
Photo 7: Removal of the supplied universal nozzle from the device

12
• Slider in the right position locks the button in the released position to prevent the
device from starting unintentionally. Activation is only possible when the button is
released.
• Slider in the left position locks the button in the pressed position so that the user
does not have to press the button the entire time of use. Activation is only possible
when the button is fully pressed. When using a device with a medium supplied
from the water supply, the activation button may become harder when pressed
due to the water pressure in the water supply. In such a case, the use of the lock is
recommended.
• When the slider is in the middle position, the button is released.
• Slider positions are shown in the Photo 8.
When using the button lock function, the device must not be operated unattended, as if
the battery is discharged, the lock must be released immediately and the battery
disconnected, otherwise the battery may be discharged excessively and damaged.

Photo 10: Connection of the device to the standing medium source
When supplying the device with the medium from the enclosed bucket, the outlet
pressure may be lower (in this case, the outlet pressure depends on the suction height
and the length of the hose from the source to the device).
When supplying the device with a medium from a bucket, river, lake or other open source
of water, it is mandatory to install a lter on the hose. If the lter is not used, internal
components may get damaged which results in reduced operating efciency or failure of
the device. The connection method is symbolically shown in Photo 10.
Flow adjustment during operation
During operation, the flow or outlet pressure can be regulated with a rotary knob on the
back of the device.
The effect of rotary knob control on outlet flow / pressure is shown in Table No. 2
(Technical specications section).
