Question 1

Should a paper filter be used to vacuum dust with the Lavor WT 30 XE vacuum cleaner?

Accepted Answer

For the Lavor WT 30 XE vacuum cleaner, a filter is mandatory for vacuuming dust. The manual clearly states: "Never use the device without having installed the filters." The paper filter (component 20) is optional, but at least one filter must always be installed.

The Lavor WT 30 XE has several interchangeable filter options:

Standard filter (components 21, 23, or 25) for dust vacuuming - mandatory
Foam filter (component 24) for liquid vacuuming only
Paper bag (component 20) optional, to be applied directly to the suction hose
HEPA filters optional for very fine dust (less than 0.3 µm)

In practice, you should always install a filter suitable for the type of vacuuming. For ordinary dry dust, use the standard filter provided with the device. The paper bag (20) is an optional additional accessory that can be added if desired, but it does not replace the requirement to have a filter installed.

Important: after each use, disassemble and shake your filter, then wash it and let it dry completely before reassembling it. If the filter is damaged or torn, replace it with an original Lavor filter to ensure optimal suction efficiency.

Question 3

What is the function and how to maintain the outlet tap of the Lavor Force 145 pressure washer?

Accepted Answer

Function of the outlet tap: On the Lavor Force 145 pressure washer, the water outlet system (gun and nozzle) allows you to direct and control the high-pressure jet. The nozzle creates the jet by propelling water at 145 bars, while the gun has a safety catch that prevents accidental triggers. The pump is equipped with a by-pass valve that automatically regulates the pressure during the machine's idle phase.

Maintenance of the nozzle and outlet: The high-pressure nozzle should be regularly inspected and cleaned, as it is the most critical outlet point. If you notice a significant drop in pressure or a weaker jet than usual, immediately clean the nozzle. Using a pin, gently remove any dirt or debris that obstructs the nozzle hole, then rinse it with water from front to back. Do not force the pin to avoid enlarging or damaging the hole.

Prevention of limescale: Limescale deposits and build-up are the main causes of nozzle malfunction. After each use, purge the system by running the pump for a few seconds without the high-pressure hose attached (in aeration phase), until the water flows out without bubbles. This operation removes residues and prevents limescale accumulation inside the nozzle.

General cleaning of the gun and lance: Clean the exterior part of the gun and lance with a soft, dry cloth. Never spray the device with water and do not use aggressive detergents or solvents. Regularly check the coupling of the high-pressure hose with the gun and the machine to ensure it is tight and there are no leaks.

Maintenance of the supply and the complete system: Also clean the filter located at the water supply connection, as a clogged filter reduces flow and affects the performance of the nozzle. Always disconnect the device from the power supply before any maintenance. The device does not require any special maintenance beyond these regular cleaning operations.

Attention: The 2-year warranty does not cover the cleaning of operating parts, filters, and nozzles clogged by limescale deposits or blocked by residues. Regular maintenance will help you avoid these problems and preserve the performance of your Lavor Force 145 pressure washer.

Question 4

What is the diameter of the water connection for the Lavor Vertigo 28 pressure washer?

Accepted Answer

The diameter of the water connection for the Lavor Vertigo 28 pressure washer is 1/2 inch (13 mm). This is the standard diameter for the water inlet fitting on this device.

For a proper and secure connection, you should use a flexible garden hose with a minimum diameter of Ø 13 mm reinforced. The manual recommends a hose length between 5 and 25 meters for optimal operation of the device.

When connecting:

Unscrew the water supply fitting located on the device
Connect the flexible supply hose (not included) to the fitting
Ensure that the seal is properly placed to avoid leaks
Tighten the hose securely

Important: the hose must not be the standard 3/4 inch (20 mm) model, but specifically a 13 mm hose. Also, ensure that the water comes from a clean or filtered source, with a maximum temperature of 40°C and a maximum inlet pressure of 1 MPa.

Question 5

How to reduce the pressure on a Lavor Vertigo 28 pressure washer?

Accepted Answer

The Lavor Vertigo 28 pressure washer has a maximum pressure of 140 bars. To adjust this pressure to your cleaning needs, several effective methods are available:

Use the supplied nozzles: Your device comes with an adjustable nozzle that allows you to change the angle and intensity of the spray. By changing the spray angle, you distribute the water over a larger surface, which reduces the impact and pressure on the cleaned surface. Test different nozzle positions to find the optimal setting based on the sensitivity of the material being cleaned.

Increase the cleaning distance: This is the simplest and most effective method. By gradually moving the lance away from the surface, the pressure naturally decreases. For delicate surfaces like car paint or vehicles, maintain a minimum distance of 30 centimeters from the spray. The further you increase the distance, the less the high-pressure effect diminishes.

Change your technique: Use the rotary brush provided with the device for less aggressive cleaning. Make slow and steady movements rather than intense and localized sprays. This approach distributes the pressure over a larger area, thereby reducing the risk of damage to sensitive materials.

Adjust the flow rate: The Vertigo 28 offers a flow rate of 420 liters per hour. If your model has a flow control, reducing it will proportionally decrease the output pressure. A lower pressure is particularly recommended for cleaning painted surfaces, woodwork, or gardens.

These different methods, alone or combined, will allow you to use your Lavor Vertigo 28 in a versatile manner, from powerful cleaning of terraces to delicate cleaning of cars or facades.

Question 6

What is the pressure in bar of the Lavor CRUISER 160 Plus pressure washer during use?

Accepted Answer

The Lavor CRUISER 160 Plus pressure washer operates at a maximum pressure of 160 bar. This pressure corresponds to the force with which water is projected, allowing for effective cleaning of various surfaces by removing dirt and stubborn stains.

Here are some important details regarding the pressure during use:

Maximum pressure: 160 bar, ideal for powerful cleaning.
Pressure adjustment: Some models allow for pressure adjustment based on the type of surface being cleaned, but for this model, the pressure is generally fixed.
Cleaning distance: It is advisable to maintain an appropriate distance between the lance and the surface to avoid damaging sensitive materials.

In summary, the pressure of 160 bar ensures sufficient power for effective cleaning while requiring careful use depending on the surfaces being treated.

Question 7

How to change the oil on the Lavor MEK 1108 pressure washer?

Accepted Answer

Changing the oil in your Lavor MEK 1108 pressure washer pump is an essential maintenance operation. You should perform the first oil change after 50 hours of operation, and then repeat this operation every 500 hours of use to maintain optimal pump performance.

Preparation before the change: Before you begin, ensure that the device is completely turned off, unplugged from the electrical outlet, and cooled down. Also, release the pressure by pressing the trigger on the lance to expel any residual water. Prepare a tray or container to collect the used oil and have a funnel ready to facilitate filling.

Removing the used oil: Locate the oil drain plug located on the pump housing (usually at the bottom of the machine). Place your drain container underneath to avoid splashes. Unscrew the plug completely and let the oil drain out completely. This step may take a few minutes depending on the oil temperature.

Cleaning and filling: Once the draining is complete, clean the area around the drain plug with a dry cloth to remove any oil residue. Then screw the plug back in tightly. Now locate the oil fill cap on the pump and pour in the recommended new oil for this model: SAE 20/30, 15W-40 or 20W-40. Use a funnel to pour the oil accurately and avoid spills.

Checking the level: Once the oil is poured in, check the level using the oil gauge if your device is equipped with one. The level should reach the maximum fill mark without exceeding it. Add oil gradually if necessary.

Finishing and testing: Screw the fill cap back on tightly. Inspect all caps to ensure there are no leaks. Plug the device in and turn it on for a few minutes to allow the new oil to circulate in the pump. Check again for any leaks around the drain and fill caps. Regular oil changes directly contribute to extending the lifespan of your pressure washer and maintaining its cleaning power.
