EN

as possible. However, it is not possible to completely eliminate these hazards. Additionally, people in the vicinity of the operating tool are also exposed to noise hazards.

However, the risks associated with the above-mentioned hazards can be reduced by observing the following guidelines:

• the product should be used in accordance with its intended use, described in the instructions manual;
• make sure that the tool is in good condition and is regularly maintained;
• use proper and well-sharpened cutting tools;
• use a fi rm grip on the product handle;
• plan work so that frequent breaks can be incorporated.

Residual risks

Even if all safety precautions are followed during operation, the potential risk of injury remains. The following risks remain in relation to the design of the product.

Vibration-related injuries caused by prolonged operation of the tool, incorrect manner of work, or work with an improperly maintained tool.

Injuries caused by an unexpected impact from hidden, ejected objects.

PRODUCT OPERATION

Preparing for operation

Unpack the product by removing all packaging components. It is recommended to retain the packaging, which can be of use when transporting or storing the product.

Check that no part of the product has been damaged during transport. In case of damage detection, such as cracks or deformations, it will disqualify the product from further use until it is repaired or damaged components are replaced.

It is recommended to place all the components on a flat, hard, and clean surface.

Use personal protective equipment such as protective gloves, eye protection, and protective clothing during assembly.

Caution! Before performing the product assembly, make sure that it is disconnected from the power supply. The device power cord plug must be disconnected from the mains socket.

When first assembling the product, it is recommended to start by assembling the correct roller with the scarifying blades or with the cleaning hooks. It will be easier to manoeuvre the device without the handlebar installed.

Caution! Due to the sharp edges of the rollers, there is a risk of injury. Take special care. Wear protective gloves for assembly.

If one of the rollers is already installed in the device, loosen the bolts of the clamp, open the clamp, dismantle the roller and close the clamp. Secure the closed clamp by tightening the fixing bolts (II). The roller is not symmetrical and on one side has a protruding element with a square cross-section; the protruding element should go to the drive socket of the same shape.

Place the device on the wheels and proceed to the installation of the handlebar. Fasten the straight bracket elements on both sides to the machine housing. The bracket is equipped with a gear that should match the sprocket wheel on the machine housing. Secure the connection with a knob (III). The sprocket wheel allows for selecting one of the three positions of the handlebar inclination. During installation, it is recommended to select the middle position and the correct height, adjusted to the operator's height, should be selected after assembling the handlebar.

Before installing the U-shaped bracket, place a holder on it for holding the power cord (IV). Then install the U-shaped bracket using the eccentric levers. Pass the lever bolt through the holes in the brackets and tighten the lever itself until its closure secures the connection of the brackets (V). Mount the handlebar with the power switch on the bracket so that the bent part of the handlebar faces upwards (VI). The handlebar with the power switch must be mounted using the lever as described when connecting the two parts of the handlebar bracket together.

Fasten the cable connecting the power switch to the verticutter housing to the handlebar bracket using the flexible clamp (VII). Install the external cover (VIII) onto the catcher frame. Then lift and hold the cover at the back of the housing in the upper position and insert the frame rods into the holes in the housing (IX). Lower the cover so that it covers the hole in the catcher (X).

EN

When assembled in this manner, the product is ready for use.

Setting the working depth (XI)

To set the working depth, use the lever, which should be moved and then introduced into the gap. The gaps are described by numbers, which indicate the working depth: 0 – transport position, 1 – 3 mm, 2 – 6 mm, 3 – 9 mm, 4 – 12 mm.

Setting the excessive working depth can lead to damage to the lawn and faster wear of the rollers, as well as to damage to their elements.

Warning! In case there is a need to change the depth during operation, always turn off the verticutter first, wait for the roller to stop, disconnect the verticutter from the power cord and then change the working depth. Accidental starting of the roller during a depth adjustment may result in serious injury.

Connecting the verticutter to the power supply

The verticutter is only equipped with a short section of power cord with a plug, that is why it must be connected with an external cable. Always use cords intended for outdoor use due to the nature of the machine work. The cable should have a single socket matching the verticutter power cord plug. It is forbidden to modify the plug or socket to make them fit. The electrical parameters of the power cord should correspond to the electrical parameters of the device, listed on the rating plate. It should be noted that the power cord's cross-section depends on the length of the cord. Follow the instructions below regarding the power cord cross-section:

• 1.0 mm ^2 – cord length not greater than 40 m;
• 1.5 mm ^2 – cord length not greater than 60 m;
• 2.5 mm ^4 – cord length not greater than 100 m.

When preparing for the operation and during operation, pay attention to the power cord. Protect the power cord from water, moisture, oils, heat sources and sharp objects. Lay the cord so that it does not come within the reach of the roller's blades. Cutting the cord may result in electric shock and serious injury or death. Make sure that you do not become entangled in the cord. This can lead to a fall and serious injury.

Do not overload the power cord, and do not cause any of the cord's section to become tensioned. Do not pull the cord when moving the device. Always disconnect the power cord plug from the socket by pulling on the plug and socket housing, never pull on the cord.

The external power supply cable near the socket to which its plug will be connected must be passed through the eyelet of the holder and then through the hook (XIII). Only then connect the power cord of the device to the external cable.

Make sure that the cable does not kink or become tensioned. Disconnect the cable from the plug as required, lengthen the loop and reconnect. Only after the external cable is properly connected to the power cord, the external cable can be connected to the mains socket.

Starting and stopping the verticutter

Place the verticutter on a flat and level place on the lawn. Set the transport working depth position. Press and hold the power switch lock button, then pull the power switch lever to the handlebar and hold it in this position. If the device starts, release the pressure on the power switch lock and grasp the handlebar with both hands.

The operation will be stopped when the power switch lever is released. The roller may still rotate for a while.

Working with the verticutter

Depending on the type of work to be done, one of the two rollers should be selected and installed correctly. A roller with blades is used to cut (scarify) the soil on which the lawn grows. The roller with springs and hooks is used to clean (verticut) the surface of the lawn, e.g. from moss or leaves. This roller with the set working depth too deep can cause damage to the lawn. It is recommended to use this roller for surface work with the minimum working depth set.

Before the proper operation, it is recommended to check the operation of the rollers at different working depth settings in less exposed places.

Before starting work, prepare the lawn. Check that there are no obstacles on the lawn that could be caught by the blades and damage the verticutter, or be ejected and pose a risk to an operator or bystanders.

The soil on which the lawn grows should not be too hard. Too hard soil will lead to faster wear of the elements that go into the ground during operation, and can also lead to a decrease in the performance of the machine and its overheating.

Check that there are no electrical cables in the work area that could be cut by the blade. Damage to an electrical cable presents a risk of electric shock, which can lead to serious injury or death.

Make sure that there are no bystanders or pets in the work area. If such persons appear during operation, stop the machine immediately and only then warn people of the danger.

Check all machine components before starting work. In case the damage is detected, do not start work before removing the damage or replacing the damaged components with new ones. Make sure that the ventilation openings are clear. If necessary, clean them with a soft cleaning tool or brush. Do not use sharp or metal objects for cleaning the product ventilation openings.

EN

Check the tightness of the screw connections. Tighten if necessary.

Check that the handlebars are clean, free of grease and other contamination. If necessary, clean them with a soft cloth.

Take regular breaks during work to avoid fatigue and overwork. This will allow better product control and reduce the risk of accidents.

Caution! Always push the verticutter while working; never pull it towards you. Pulling the verticutter causes the operator to move backwards, which means no control over the area behind the operator's back. In addition, when pulling the verticutter backwards, the blades can catch the power cord.

Push the verticutter slowly; always walk, never run. This will give you better control of the machine and reduce the response time to unexpected events.

During operation, move along the rows (XIV). Rows should be kept equal in width, slightly overlapping so as not to leave any space. Take special care when changing the direction.

Make sure to begin work from the electrical connection side. This will reduce the risk of driving over the power cord.

When working near the flower beds, move around them.

Empty the catcher regularly during operation. It is also possible to work without the catcher, but make sure that the cover completely covers the outlet opening at the back of the housing. Objects caught by the rotating roller may be ejected through the uncovered or partially covered outlet opening, which may be dangerous for the operator and/or bystanders.

Warning! Never open the outlet opening cover while the machine motor is running and the rollers are rotating.

When work is finished, turn off the verticutter, wait for the roller to stop, then disconnect the power cord and wait for the machine to cool down, then start maintenance works.

Caution! If a foreign object hits the verticutter during operation, immediately turn the product off, wait for the roller to stop, then disconnect the power cord, and allow the verticutter to cool down. Then check the verticutter for damage. If the damage is detected, it is forbidden to continue working before removing the damage. Excessive vibration during operation can be caused by damage to the machine. In that case, stop working, disconnect the power cord, and check the product.

PRODUCT MAINTENANCE

Caution! Make sure that the product is disconnected from the power supply before starting any maintenance works. The power cord must be disconnected from the machine.

Always wear protective gloves during all maintenance works.

If the maintenance procedure is not contained in the instructions manual, it means that it should be performed at an authorised service centre.

Clean the product after each use. Remove any residual grass and soil with a soft cleaning tool, brush or cloth. Clean the ventilation openings to ensure that they are clear.

Dirt that is difficult to remove can be cleaned with an air jet with a pressure of up to 0.3 MPa.

Never use chemicals, alkaloids, abrasives, or aggressive detergents to clean the product. The product cannot be cleaned with a water jet or by immersion in water.

Check for wear and damage to the roller blades. If excessive wear or damage is observed, replace the roller with a new one.

Always replace the roller with the original one, identical to the one delivered with the product. Only the use of original spare parts can maintain product safety.

After each use and cleaning of the metal roller elements, they should be covered with a thin layer of light general purpose lubricating oil. This will reduce corrosion and increase metal elements service life.

The roller should be replaced when a significant deterioration in the performance of the device is observed.

After each operation, the grass catcher must be removed and emptied of the grass. The catcher can be cleaned with lukewarm water with suds. After cleaning, leave the catcher in the working position until completely dry.

If the internal cable connecting the product power switch to the motor is damaged, it must be replaced by an authorised service centre of the manufacturer. The cable cannot be repaired and must be replaced entirely. It is forbidden to operate the product with a damaged cable.

STORAGE AND TRANSPORT

Caution! Always disconnect the product from the power supply before storing or transporting it. Clean according to the instructions.

Store in the dark, dry, frost-free, and well-ventilated areas. The place of storage should protect the tool from access by children.

The product should be stored at a temperature between 10^ C and 30^ C. It is recommended that the product is stored in its original packaging or another packaging that protects it from dust.

Before transporting the product, set the working depth lever to the transport position. Transport the product by carrying it by the handles. Protect the product from impacts and strong vibrations during transport. Secure the product against slipping or tipping over during transport.
