ADDITIONAL SAFETY INSTRUCTIONS
The tool has been designed exclusively for polishing. Get acquainted with all the warnings, instructions, illustrations and specifications supplied along with the electric tool. If the instructions below are not observed, there is a risk of electric shock, fire and / or serious injuries.
It is prohibited to use the tool as a grinding, sanding and cut-off machine or in a way which does not comply with the manual. Using the tool for jobs it is not designed for implies a risk and may cause injuries.
Do not use accessories which have not been designed and are not recommended by the manufacturer. The fact that accessories may be installed in the tool does not mean work with them is safe.
The maximum rotational speed of the accessories must be higher than or equal to the maximum rotational speed of the tool. Accessories of a lower rotational speed than the speed of the tool may break during work.
The outer diameter and the thickness of accessories must fall within the range of dimensions indicated for the tool.
Accessories of incorrect dimensions cannot be properly protected and operated.
Threaded mounting of accessories must match the grinder spindle thread. The dimensions of the hole in which wheels, disks, flanges and other accessories are installed must comply with the dimensions of the spindle of the tool. Accessories in which the dimensions of the fixing hole do not comply with the dimensions of the spindle of the tool, will vibrate after start, which may preclude a proper control of the tool.
EN
Do not use damaged accessories. Before each use, make sure the accessories are not splintered, broken or excessively worn. If accessories are dropped make sure they are not damaged or install new accessories. Once accessories have been inspected and installed, all persons must remain away from the plane of rotation of the accessories, and start the tool for a minute with the maximum rotational speed. During the test damaged accessories will be destroyed.
Use individual protection means. Depending on the job, wear face protections or safety goggles. If it is required use dust masks, hearing protectors, gloves and aprons protecting from small fragments of the accessories or materials generated during work. Eye protection must stop flying pieces generated during work. The dust mask must filter dust generated during work. Excessive exposition to noise may lead to hearing impairment.
While realising tasks during which the disc may come into contact with a hidden live electric wire or a power supply cable hold the grinder by insulated handles. If the disc touches a live wire, the metal elements of the tool may cause electric shock to the operator of the tool.
Maintain a safe distance between the place of work and third persons. Persons who approach the place of work must use individual protection means. Chips generated during work or fragments of damaged accessories may be ejected beyond the direct vicinity of the place of work.
Place the power supply cord away from the rotating wheels. In case the operator loses the control over the tool, the cord may be cut or caught, and the hand or arm of the operator may be drawn into the rotating elements of the machine.
Never put down the tool until the rotating elements have stopped completely. The rotating elements may „catch“ the ground and impede the control of the tool.
Do not start the tool while carrying it. Accidental contact with the rotating elements may cause drawing clothes and contact of the tool with the body of the operator.
Clean the ventilating holes of the tool regularly. The ventilator of the motor pulls the dust generated during work into the tool.
Excessive accumulation of metal particles contained in the dust increase the risk of electric shock.
Do not operate the tool in the vicinity of inflammable materials. The sparks generated during work may cause a fire.
Do not use accessories which require cooling with liquids. Water or cooling liquid may cause an electric shock.
Warnings related to the possibility of the tool rebounding towards the operator
Rebounding of the tool towards the operator is caused by a sudden reaction to blocked or seized discs or polishing belts or another accessory, which causes a sudden stop of the rotating accessory and a turn of the electric tool opposite to the direction of rotation.
For example, if the grinding disc is seized by the object being processed, the edge of the disc, which is at the point of seizure may get deeper into the surface of the material, and thus get ejected.
The disc may also move towards or away from the operator, depending on the direction of movement of the grinding wheel at the place of seizure. Grinding wheels may also break.
Rebounding of the tool towards the operator is caused by incorrect operation and / or inobservance of the indications contained in the operating manual. It may be prevented if the following recommendations are followed.
Hold the tool firmly and adopt an adequate position of the body and the hands, which will permit you resist the force generated when the tool rebounds. Always use the additional handle, if it has been supplied with the tool, which will ensure a maximum control when the tool rebounds or turns inadvertently during start. The operator is able to control the turning or rebound of the tool, if adequate safety measures have been taken.
Do not ever place hands close to the rotating elements of the tool. The rotating elements may, in case the machine rebounds, get into contact with the hand.
Do not remain within the area into which the tool will move in case of rebound. A rebound will propel the tool in the direction opposite to the rotation of the grinding disk, where it is seized.
Be particularly careful during work close to corners, sharp edges, etc. Avoid flicking up and seizure of the grinding disk.
During work on corners or edges there is an increased risk of seizure of the grinding disk, which may imply a loss of control over the tool or rebound of the tool.
Do not use disks with cutting chains or disk saws. The edges cause frequent rebounds, which may lead to a loss of control over the tool.
Warnings related to polising operations
Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely. Tuck away or trim any loose attachment strings. Loose and spinning attachment strings can entangle your fingers or snag on the workpiece.
Warnings related to grinding with abrasive paper
Do not use discs with abrasive papers of an excessive size. While selecting the grinding wheel, follow the guidelines of the manufacturer. Abrasive paper which significantly exceeds the size of the disc may cause injuries and increases the risk of seizure, tearing or rebounding towards the operator.
PREPARING THE MACHINE FOR OPERATION
Warning! Before installation, replacement or removal of accessories, make sure that the battery is disconnected from the tool and that the switch is locked.

Safety recommendations for battery loading
Attention! Before loading may start make sure the body of the charger, the cable and the plug are not broken or damaged. It is prohibited to use a damaged loading dock and charger! For the purpose of loading batteries only the charging dock and the charger provided may be used. Using another charger may be a cause of fire or damage the tool. Batteries may be charged only in a dry room, protected from unauthorised persons, particularly children. Do not use the charging dock and the charger without permanent supervision of an adult! If it is necessary to leave the room where loading is taking place, it is required to disconnect the charger from the mains, removing the charger from the mains socket. In case when smoke comes out of the charger, or a strange smell is emitted, etc., it is required to immediately remove the plug of the charger from the mains socket!
The drill and automatic return screwdriver is provided with an unloaded battery, so before work may commence, it is required to charge it following the procedure below, using the charger and charging dock provided. Li-ION batteries do not show the so called “memory effect”, so it is allowed to charge them at any moment. However, it is recommended to discharge them during normal work, and then load them to their full capacity. If due to the nature of the task it is not possible to do so each time, then it is required to do it at least from time to time. Under no circumstances is it allowed to discharge the batteries short-circuiting the electrodes, since this would cause irreversible damage! It is also prohibited to check the load of the batteries, short-circuiting the electrodes for sparking.
Storage of the battery
In order to prolong the life of the battery, it is required to provide adequate storage conditions. The batteries can go through approximately 500 „loading - discharging” cycles. The battery must be stored between 0 and 30°C, at the relative humidity of 50%. In order to store the battery for a prolonged period, it is required to charge it to approximately 70% of its capacity. In case of prolonged storage, it is required to recharge the battery once a year. Do not permit excessive discharging of the battery, since this would reduce its life and may cause irreversible damage.
During storage, the battery will be gradually unloading due to leakage conductance. The process of automatic unloading depends on the temperature of storage, since the higher the temperature, the fastest the process. In case of incorrect storage of batteries, there is a danger of electrolyte leakage. In case of leakage, it is required to protect the leakage with neutralizing agent. In case of contact of electrolyte with the eyes, it is required to rinse the eyes abundantly, and then immediately seek medical assistance. It is prohibited to use a tool with a damaged battery.
In case the battery is completely worn out, it is required to deposit it at a special point dedicated to disposal of such waste.
Transport of the batteries
Lithium-ion batteries are in accordance with legal regulations treated as dangerous waste. The user of the tool may transport the tool with the battery or only batteries by land. Then no additional conditions must be complied with. In transport is realised by third parties (for example dispatch through courier service), then it is required to proceed in accordance with regulations for transport of dangerous materials. Before shipment, contact an authorised person.
It is prohibited to transport damaged batteries. During transport the battery must be removed from the tool, and the exposed contacts protected, e.g. with insulating tape. Protect the batteries so that they do not move inside the package during transport. It is also required comply with the national regulations for transport of dangerous materials.
