GENERAL WARNINGS FOR THE SAFETY OF POWER TOOLS

Warning! Read all safety warnings, illustrations and specifi cations provided with this power tool. Failure to do so may result in electric shock, fi re or serious injury.
Keep all warnings and instructions for future reference.
The term “power tool” used in warnings applies to all tools driven by power both wired and wireless.
Workplace safety
Keep the workplace well-lit and clean. Disorder and poor lighting can be causes of accidents.
Do not work with power tools in an environment with an increased risk of explosion, containing flammable liquids, gases or vapors. Power tools generate sparks that can ignite dust or fumes.
Children and third persons should not be allowed to enter the workplace. Loss of concentration can result in loss of control.
Electrical safety
The plug of the electric cable must match the power socket. You must not modify the plug in any way. Do not use any plug adapters with earthed power tools. An unmodifi ed plug that fi ts the outlet reduces the risk of electric shock.
Avoid contact with earthed surfaces such as pipes, radiators and coolers. Grounding the body increases the risk of electric shock.
Do not expose power tools to contact with atmospheric precipitation or moisture. Water and moisture that gets inside the power tool increases the risk of electric shock.
Do not overload the power cable. Do not use the power cord to carry, pull or unplug the power plug from the power outlet.
Avoid contact of the power cable with heat, oils, sharp edges and moving parts. Damage or entanglement of the power cord increases the risk of electric shock.
In the case of working outside closed rooms, use extension cords intended for work outside closed rooms. The use of an extension cord adapted for outdoor use reduces the risk of electric shock.
When using a power tool in a humid environment is unavoidable as a protection against supply voltage use a residual current device (RCD). The use of RCD reduces the risk of electric shock.

Personal safety
Stay alert, pay attention to what you do and keep common sense while working with the power tool. Do not use a power tool when you are tired or under the infl uence of alcohol or medication. Even a moment of inattention while working can lead to serious personal injury.
Use personal protective equipment. Always wear eye protection. The use of personal protective equipment such as dust masks, anti-slip safety shoes, helmets and hearing protection reduce the risk of serious personal injury.
Prevent accidental operation. Make sure that the electric switch is in the “off ” position before connecting to the power supply and / or battery, lifting or moving the power tool. Moving the power tool with the fi nger on the switch or powering the power tool, when the switch is in the “on” position can lead to serious injuries.
Before turning on the power tool remove any keys and other tools that were used to adjust it. The key left on the rotating parts of the power tool can lead to serious injuries.
Do not reach and do not lean too far. Keep the right attitude and balance all the time. This will allow easier control over the power tool in case of unexpected work situations.
Dress accordingly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts of the power tool. Loose clothing, jewelry or long hair can be caught by moving parts.
If the devices are fitted for the connection of dust extraction or dust collection, make sure that they are connected and used properly. The use of dust extraction reduces the risk of dust hazards.
Do not let the experience acquired from frequent use of the tool resulted in carelessness and ignoring safety rules.
Carefree action can cause serious injuries in a fraction of a second.

Use and care of the power tool
Do not overload the power tool. Use the power tool appropriate for the selected application. The right power tool will provide a better and safer job if used according to the designed load.
Do not use the power tool, if the electric switch does not allow switching on and off. Power tool, which cannot be controlled by means of a power switch is dangerous and must be returned for repair.
Disconnect the plug from the power socket and / or remove the battery if it is detachable from the power tool before adjusting, changing accessories or storing the tool. Such preventive measures will allow you to avoid accidentally turning  on the power tool.
Keep the tool out of the reach of children, do not let people who do not know how to operate the power tool or these instructions use a power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools and accessories. Check the tool for mismatches or jams of moving parts, damage to parts and any other conditions that may affect the operation of the power tool. Damage must be repaired before using the power tool.
Many accidents are caused by incorrectly maintained tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp edges are less prone to jamming and are easier to control when working.
Use power tools, accessories and inserted tools etc. in accordance with these instructions, taking into account the type and conditions of work.
The use of tools for work other than designed is likely to result in a dangerous situation.
Handles and gripping surfaces must be dry, clean and free from oil and grease. Slippery handles and gripping surfaces do not allow for safe operation and control of the tool in dangerous situations.
Repairs
Repair the power tool only in authorized facilities using only original spare parts. This ensures proper operation safety of the power tool.

SAFETY INSTRUCTIONS FOR CUTTERS

Safety warnings for cutting equipment
The guard supplied with the tool must be safely attached to it and adjusted in a position that provides a maximum level of safety — so that as little part of the cutting disc as possible is exposed towards the operator. Position yourself and unauthorised persons away from the rotating disc plane. The guard helps will protect the operator from fragments of a broken disc and accidental contact with the disc.
Use only diamond cutting discs in the cutter. Just because an accessory can be mounted in a power tool does not make it safe to operate.
The rated speed of the accessory must be at least equal to the maximum rated speed indicated on the power tool. Acces­sories moving faster than their rated speed may break and fall apart.
Discs must only be used for recommended applications. For example, do not grind with the side surface of discs for cutting. Cutting grinding wheels are designed for edge grinding; lateral forces applied to them may cause them to fall apart. Always use undamaged mounting flanges that are the right size for the selected disc. Right fixing flanges strengthen the disc and reduce the possibility of its falling apart.
The outer diameter and thickness of the accessory must be within the rated range of the power tool. It is not possible to properly protect or operate improperly sized accessories.
The size of the disc mounting hole and flanges must match the size of the power tool spindle. Discs and flanges with a fixing hole size not suitable for the tool spindle size loose their balance and will start to vibrate during operation, which may result in the loss of control over the tool.
Do not use damaged cutting discs. Before each use, check the discs for splinters and cracks. If any discs are dropped, make sure they are not damaged, or mount new, undamaged discs. After you have checked and installed the discs, make sure you and all bystanders stand outside the rotation plane of the discs, then run the power tool for one minute at maximum speed without load. Damaged discs usually fall apart during the test.
Wear personal protective equipment. Use face shields, goggles, or safety goggles, depending on the application. If applicable, use dust masks, hearing protection, safety gloves, and aprons capable of protecting against small pieces of the grinding wheel or splinters generated during work. The eye protection must be capable of stopping any flying debris gen­erated during different jobs. The dust mask must be capable of filtering out particles generated during work. Prolonged exposure to noise can cause hearing loss.
Keep a safe distance between bystanders and the work area. Any person entering the work area must wear personal protective equipment. Splinters produced during the work or splinters of damaged accessories  may be thrown outside the immediate vicinity of the work area.
Hold the tool by the insulated grips only, when working where the cutting accessory may come into contact with the hidden cord or power cord of the tool. The cutting accessory coming into contact with live cable causes the metal parts of the tool become live and electrocute the operator.
Keep the cable away from the rotating accessory. If you lose control, the cord can be cut or drawn in, and your hand or arm can be pulled towards the rotating disc.
Never put the power tool down until the accessory has stopped completely. A rotating accessory can catch the surface and pull the power tool, depriving you of control of it.
Never operate the power tool while holding it on your side. Accidental contact with a rotating accessory can catch your cloth­ing by pulling the accessory towards your body.
Clean the power tool’s ventilation openings regularly. The motor fan can suck dust inside the housing, excessive accumula­tion of powdered metal may result in the risk of electric shock.
Do not use the power tool near flammable materials. Do not operate the power tool if it is placed on a combustible sur­ face, for example a wooden surface. Sparks can ignite such materials.
Caution! Kickback towards the operator The kickback towards the operator is caused by a sudden reaction to a locked or jammed rotating disc or other disc. Locking or jamming causes the rotating disc to lock suddenly, which results in the uncontrolled cutting head being pushed up towards the operator.
For example, if the abrasive disc is blocked or jammed in the material being processed, the disc edge which enters into the jamming point may penetrate the surface of the material, causing the disc to get out or be ejected.
The disc can also be ejected towards or away from the operator, depending on the direction of the grinding wheel movement at the jamming point. Abrasive discs may also break in these conditions.
The kickback towards the operator is a result of misuse of the power tool and/or improper operating procedures or conditions and can be avoided with appropriate remedies as outlined below.
Use a firm grip on the power tool and the correct position of the body and arms which withstand the kickback forces. The operator will be able to control the tool rotation or the kickback if appropriate precautions are taken.
Keep your hands away from the rotating accessory. The accessory may kick back towards your hands.
Never place your body in the rotating disc line. If a kickback occurs, it will point the cutting head towards the operator.
Pay special attention when machining corners, sharp edges, etc. Avoid raising and jamming the accessory. Corners,

Pay special attention when machining corners, sharp edges, etc. Avoid raising and jamming the accessory. Corners,

heavy pressure and the lateral forces applied to such a disc may cause it to fall apart.
Do not use wet cutting discs for dry cutting. Do not use water cooling for dry cutting discs only. Do not use any liquids other than water for cooling. If the type of disc used allows for water cooling, they should always be used. This will  reduce the amount of dust generated during operation, as well as extend the life of the disc.
A diamond disc intended for dry cutting does not require water cooling, but its overload will lead to premature wear and may cause damage, which may result in injury. It is recommended to remove the disc from the cut every 30 – 60 seconds and allow it to spin for approx. 10 seconds. This will cool the disc.
Never cut asbestos or materials containing asbestos. Dust from cutting asbestos is particularly hazardous to health and has been classifi ed as a carcinogen.
Always use undamaged fi xing fl anges, which are the correct size for the cutting disc. The correct fi xing fl anges of the abrasive disc reduce the possibility of damage to the cutting disc.
If the disc is equipped with spacers, use them during the installation of the discs. The thickness of the spacers must not exceed 0.5 mm.
Do not use worn discs from larger tools. A larger diameter disc is not suited for a higher rotational speed of smaller tools and maybreak.
Always run up the disc to rated speed before cutting. Do not change the disc speed during cutting. Pay special attention whenrestarting the cutting. Run up the disc to rated speed fi rst and then carefully insert the disc into the cutting slot. If the disc is jammed in the material being cut, turn off the tool immediately and keep it still until the disc stops completely. Never

TOOL OPERATION

Preparing for operation
Warning! All assembly, disassembly and adjustment of the tool must be carried out with the power supply switched off . Make sure that the power cord is unplugged from the mains outlet.
Before starting work, attach the disc or make sure that it is attached correctly. Press and hold the spindle lock button with your finger and turn the spindle slowly until its rotation is locked (II). Do not release the lock button. With the  spindle locked, unscrew the mounting screw clockwise and remove the outer fl ange securing the disc. Place the disc on the spindle and the inner mounting
flange (iii).
Then install the external fixing flange and, with the spindle locke, tighten the fixing screw (IV) counter-clockwise.

In the case of “wet” cutting, connect the hose to the valve already connected to the tool.
The valve can be adjusted in 2 positions
(V). If the knob is perpendicular to the hose, it means closed valve, and if the knob is in line with the hose, it means open valve.
The other end of the hose is equipped with a flexible adapter to connect the hose to the water supply.

MAINTENANCE, STORAGE AND TRANSPORT

CAUTION! Before carrying out any adjustment, servicing or maintenance work, unplug the tool from the power outlet. Having fi nished working with the workpiece/material, inspect the power tool for damage by visually inspecting the  exterior and the body and the handles. Check the power cord, the plug, the action of the ON/OFF switch, the vents for clogging, the motor brushes for sparking, the noise of the bearings and the drive transmission, and how the power tool  starts and runs. During the warranty period, the user is not allowed to install any power tools or replace any components or parts, as this will void the warranty rights. Any abnormality found during this inspection or the operation require  servicing at an authorized service agent’s. Having fi nished your work, clean the housing, the vents, all switches, all handles and guards with compressed air at 0.3 MPa maximum, a brush or a dry cloth. Do not use any chemicals or  cleaners. Clean the tools and chucks with a clean, dry cloth. The product should be stored thoroughly cleaned and dried. Store the product indoors. Secure against unauthorized access. Ensure adequate ventilation to prevent water vapour  condensation at the place of storage. The place of storage should protect the product from weather conditions.
The product should be transported in unit packaging or other hard packaging, providing protection against shocks. Protect the product from moisture during transport.
When replacing the disc or more frequently, especially if symptoms such as leaking spark shield interiors, dust, uneven rotation, increased vibration are observed during unloaded operation, thoroughly clean the inside of the guard. To do  this, remove the cutter base, then remove all latches located on the edge of the guard (XX). This will open the guard cover (XXI). Remove the disc and clean the inside of the guard with a soft-bristle or plastic brush. Do not use sharp or  metal objects for cleaning the guard. After cleaning, close the guard and secure it with the latches.
