Labor productivity when using the sprayer increases by 4-6 times compared to a mechanical device, saving time and reducing fluid consumption.

Depending on the model, the equipment may vary. The set of the MINI model for 8 liters is inexpensive in the Comfort line, but includes all the necessary elements for work.

1. Sprayer assembly – 1 pc.
2. Pressure hose – 1 pc.
3. Removable filter – 1 pc.

The main differences are a short boom with adjustable length from 39 cm to 80 cm, a discharge hose of 1.5 meters and two nozzles on the boom. In general, the complete set of the device meets the needs of the gardener, providing ease of use, efficiency in work.

Characteristics

The main technical characteristics of the sprayer Umnitsa OE 8L are related to the capacity of the tank, the type of battery (its capacity and voltage), the capacity and pressure of the pump, as well as the weight. The technical passport states that the device has:

• A plastic housing with a capacity of 8 liters, resistant to chemical solutions.
• Lead-acid battery 6 volt 12 a/h.
• Diaphragm electric pump with a capacity of 3 liters per minute and a pressure of 0.35 MPa.
• Operating temperature from +1 to +43.
• The mass of the empty device – 3 kg.

In addition to the main parameters of the sprayer, there are not so important, but facilitating maintenance and work, it is possible:

• removal of filters for washing;
• pump power adjustment;
• voltage control with a voltmeter.

Housing

The tank of the sprayer OE 8 MINI is made of ABS (Acrylonitrile Butadiene Styrene) plastic, known for its strength and resistance to mechanical influences. But still, it is better to avoid sharp impacts or falls to avoid damage.

The 8-liter tank capacity provides enough liquid to treat small to medium-sized areas without the need for frequent refilling.

The weight of a refilled Umnitsa sprayer does not exceed 11 kilograms, which makes it easy to carry the device both in the hand and on the shoulder. For this purpose, the sprayer is equipped with an ergonomic handle and an adjustable shoulder strap.

The pump, battery, voltmeter, pump speed control and charging connector are located at the bottom of the body (under the tank).

Do not allow water or spray liquid to enter the lower part of the housing. This may lead to premature breakdown of the device.

It is worth noting the color of the body of the apparatus smart OE 8L Mini – it is orange. In the line of Comfort models there is a model with a lithium battery – Umnitsa OEL 8L Mini, with a pink color of the case.

Battery

Lead-acid battery with a capacity of 12 Ah provides the work of the automatic pump sprayer MINI from 2 to 3 hours. The charge is enough to treat the garden at the dacha or homestead.

Control of the charge level is carried out with the help of a voltmeter, which has three color zones.

• N – normal, green zone.
• L – low, yellow color.
• H – low, red LED.

When the battery voltage is low, the voltmeter glow will move first to the yellow area and then to the red area. Low voltage does not provide the proper pump pressure, so atomization quality will be impaired.

You can increase the pump power by turning the knob clockwise using the regulator next to the switch. Please note that the increased power discharges the battery faster, which can lead to premature battery failure.

To restore performance, the battery must be charged. The charger will fully charge the battery within 3-4 hours.

Pump

The diaphragm pump used in the device creates a maximum pressure of 0.35 MPa and has a capacity of 3.5 l/min, which shows its high efficiency. The value of 0.35 MPa is 3.56 kgf/cm², i.e. 3.56 atmospheres, which is more usual for us.

Note that diaphragm pumps are sensitive to the purity of the solution. Debris in the tank can clog the filter and cause the pump to malfunction. The pressure will drop and the atomization will become insufficient.

Filters

There are 3 filters in the device of the 8L MINI sprayer:

• in the neck of the tank;
• bottom;
• boom handle.

The primary filter of coarse cleaning is installed in the filler neck – it detains large debris.

A pump filter is installed on the bottom of the tank in front of the intake opening. It protects the pump and atomizer from small particles.

There is an additional coarse filter in the sprayer handle. It has rather large cells and can only catch large fragments, so it does not play a special role.

Anything that is not trapped by the filter in the tank will get into the sprayer head. Atomization will become uneven and weak.

Hose and boom

The sprayer is equipped with a hose length of 1.5 meters, which is quite enough for convenience in work.

The hose together with a telescopic handle of 80 cm allows you to treat trees up to 3 meters high. For taller trees, you need to buy a long boom or use a stepladder.

In the set of sprayer Umnitsa MINI there are two types of nozzles that allow you to change the width and intensity of atomization of the solution. This is important for achieving the desired coverage on plants and trees, taking into account their characteristics.

The nozzle with a single nozzle is suitable for spot treatment of plants or narrow areas. It has a working range of up to two meters with an angle of 0 to 60°. The double nozzle sprayer is suitable for large areas with a maximum spray angle of 120°.

The spraying angle is changed by rotating the nozzle tip cap.

Operation

Before starting work, inspect the sprayer to make sure that it is not damaged. Check the battery charge level and charge if necessary. It is not unreasonable to check the cleanliness of the filters. Having finished the inspection, assemble the device.

The solution can be poured ready-made or prepared in the tank capacity. At the same time, make sure that the water is clean.

Turn the switch to the “On” position and the sprayer is ready to work. The operation process of the electric sprayer is similar to that of the pneumatic sprayer.

If the pressure in the pneumatic device was created in advance, in the electric device it is created by the pump. When you press the spray lever, the valve opens, the pressure in the hose drops and the pump begins to work.

It is worth noting that the electric sprayer Umnitsa OE-8 MINI has a simple control system, which makes it available even for those who have no experience in working with such devices.

The solution is refilled as it is consumed. The battery charge is enough to spray several tanks.

When working with chemicals, you need to use special clothing, safety glasses, respirator and gloves.

After finishing the work, the sprayer should be washed, and when storing for the winter, be sure to dry.

Pros and cons of the device

According to user reviews, the electric sprayer Umnitsa OE 8L MINI is an excellent device. Compared to a pneumatic apparatus, it greatly facilitates work in the garden. When looking for a device for spraying plants in your farm, it is recommended to pay attention to this model.

• the pump;
• battery;
• sprayers.

The battery and pump are the most responsible parts, and if the battery and nozzles will easily last a year, the pump, as a highly loaded part can break. Given that everything is made in China, it may well be.

There are no particular disadvantages to this model. Put in the minus of a short boom or a small number of nozzles is not worth it, since this is determined by the package.
