Preparing the angle grinder for use

WARNING
Perform installation, service or maintenance tasks on the angle grinder with the battery removed from the angle grinder to eliminate the risk of accidentally star-ting the power tool.

INSTALLATION OF THE ADDITIONAL (FRONT) HANDLE

WARNING

• The angle grinders must not be used without the front handle installed.
  Screw the additional front handle into the respective hole in the body of the angle grinder based on the required holding position of the angle grinder.
  

• For cutting, screw it into the hole on the right or left side of the angle grinder based on whether you are right- or left-handed.

• For planar sanding/grinding, screw it into the hole in the top part of the angle grinder.

GUARD – INSTALLATION – POSITION (PROTECTIVE USER ZONE)

POSITION OF THE GUARD

WARNING

• On to the neck of the angle grinder, install the guard, which must be positioned so that, during the use of the angle grinder, it covers the largest part of the disc in the direction towards the user based on the holding position of the angle grinder and protects the user to the maximum degree possible against deflected material fragments, sparks and disc fragments. The protective user zones for the given position of the angle grinder guard are shown in fig. 2. When the grinding part of the disc (work tool) needs to be changed, adjust the position of the angle grinder guard to create a protective zone for the user.

INSTALLING THE GUARD

• Place the metal tab on the collar of the guard into the ingress in the neck of the angle grinder so that it is possible to place the tab into the groove on the neck of the angle grinder and then turn the guard with the tab in the groove to the required position. Then tilt down the lever of the quick-clamping mechanism and secure the guard on the neck of the angle grinder by screwing in the nut using a suitable installation tool. Screw the nut in so that the guard is properly secured in position and that the quick-clamping lever can be tilted open without the nut needing to be loosened for the case that the position of the guard needs to be adjusted. If the lever of the quick-clamping mechanism cannot be opened, do not loosen the nut more than necessary.

INSTALLATION/REPLACEMENT OF A DISC

1. Place the washer (fig. 3A or fig. 3B, position 2) on to the spindle of the angle grinder so that it is seated in the ingress of the spindle and turns with it. Use your hand to check that it is correctly seated.

2. place the disc on to the washer (fig. 3A or 3B, position 3).
   WARNING
   If the disc has a cupped curve, then the disc must be seated on the washer with the convex face downwards, see fig. 3A and 3B.

3. Screw the outer clamping nut on to the spindle of the angle grinder (Fig. 3A or 3B, position 4). To clamp a thicker (grinding) disc with a maximum thickness of 6 mm, screw the clamping nut with the side of the raised ring towards the disc (Fig. 3A, position 4). To clamp a thin (cutting) disc, screw in the clamping nut facing the disc with the side without the raised ring (Fig. 3B, position 4).

INSTALLING PERMITTED ACCESSORIES ON TO THE SPINDLE OF THE ANGLE GRINDER

WARNING

• In the event that the angle grinder will be used with accessories having a M14 thread (e.g. wire brush, sanding cut-out holder), prior to screwing on such an accessory on to the spindle of the angle grinder, first remove the bottom washer and screw out the clamping nut and then screw on the required accessory by hand.

WARNING

• The accessories must be intended for use with an angle grinder, whilst the maximum permitted rotation speed (marked on the accessory) must not be lower than the speed of the angle grinder when running without load (see rating label on the angle grinder). The fact that the accessory can be attached on to the spindle of the angle grinder is does not mean that it is safe to use it with the angle grinder.   It is forbidden to install accessories with a larger diameter and dimensions than specified in the chapter with the technical specifications. Under no condition may the angle grinder guard be removed for the purpose of using accessories with a larger than permitted diameter.

INSERTING A BATTERY INTO THE ANGLE GRINDER

• Insert the battery into the angle grinder according to fig. 1, so that it clicks in.

Using the angle grinder

WARNING: When using the angle grinder, follow the instructions in the safety instructions. Fig. 4 to 7 show the correct and incorrect methods of work for the various work activities according to the used work tool.

CUTTING WITH CUTTING DISCS

• While cutting, the angle grinder must be held perpendicular to the plane of the material being cut for the entire duration of the cut and must not be tilted to the sides (see fig. 4). The angle grinder is not intended for cutting with a cooling liquid.
• While cutting, the workpiece must be firmly secured using suitable clamping tools and when cutting longer workpieces, the workpiece must be supported under both sides near the cutting location to prevent the clamping of the disc inside the cut.
• When performing planar sanding/grinding using the grinding discs (max. thickness 6 mm) or cutting with a cutting disc, prevent the disc from jumping up and down on the workpiece.

PLANAR SANDING/GRINDING

• For planar sanding/grinding, screw the additional handle into the hole on the „nape“ of the angle grinder.
• When grinding/sanding using flap discs, keep the disc at an angle of approx. 15° relative to the grinding plane (fig. 5).
• When planar sanding/grinding (using flap discs or sand- paper mounted on a bearing disc), do not exert excessive pressure on the angle grinder since the power tool‘s own weight is sufficient. Move the angle grinder in circular motions over the surface of the grounded material.

BRUSHING WITH WIRE BRUSHES

When brushing with wire brushes, do not exert downward pressure on the brush as this worsens the effectiveness of work, accelerates wear and tear of the brush and put too much load on the angle grinder (fig. 6). When using a wire cup brush guide it at an angle of 15° relative to the ground/sanded surface (fig. 7).

WARNING

• In the event that there is an unusual noise, vibrations or operation while the power tool is running, immediately turn off the power tool, disconnect it from the el. power supply and identify and rectify the cause of this unusual operation. If the unusual operation is caused by a fault inside the power tool, have it repaired at an authorized service center for the Extol® brand through the vendor or directly at an authorized service center (service locations are listed at the website address at the start of this manual).

FORBIDDEN USE

• Without an additional external dust extraction connection adapter being installed, the angle grinder must not be used for cutting and grin-ding/sanding materials during which a significant amount of dust is generated such as for example grooving of masonry, cutting plasterboard, bricks, tiles and ceramics since this would result in the motor burning up due to the clogging of the motor vents with dust or to the short-circuiting of the trigger due to the accumulated dust becoming damp inside the trigger, or other types of motor damage caused by dust. For this purpose, there are special masonry grooving machines or tile cutters that have greater protection against generated dust with a differently adapted guard, which is additionally equipped with a socket for attaching external dust extraction, which angle grinders do not have in the standard design. The fact that it is possible to clamp cutting discs intended, amongst other things, for cutting or grooving masonry, does not necessarily mean that it is possible to cut materials with an angle grinder when the angle grinder is not intended for such cutting (see also described determining use contained in user‘s manuals of professional angle grinders of other brands on the market).

WARNING
Extraction adapters intended for installation on angle grinders with a disc diameter of 125 mm are supplied to the market by several manufacturers. For the safe use of the angle grinder with the extraction adapter it is, however, necessary for the extraction adapter to be properly installed and secured on to the angle grinder, whilst the extraction adapter must enable the proper and safe clamping of the disc on the spindle under the condition that the disc must not be touching any part of the guard. After installation of the extraction adapter on the angle grinder and before starting it, first check that the extraction adapter has been safely installed and that the disc is safe for operation of the angle grinder.

INFORMATION ABOUT PROTECTION AGAINST OVERLOADING AND FULL BATTERY DISCHARGE

The battery is equipped with protection against full discharge and overloading, which damages it. This protection manifests its self by the power tool coming to a sudden stop even when the trigger switch is pressed, when the battery has been discharged multiple times. When the trigger switch is released and then pressed again, the power tool will start again for a short time, but then it will stop running again. This is not a fault, but rather serves as protection. For longer term operation or greater load (e.g. grin- ding) it is necessary to use a battery with a higher capacity.

Safety instructions for all work activity

Safety warnings common for the work activities of sanding, planar grinding, grinding with wire brush or abrasive cutting.

• This power tool is intend for use as a sander, planar grinder, wire brush grinder or as
  a cutting tool. It is necessary to read all the safety warnings, instructions, illustration and specifications given for this power tool. Not adhering to all the instructions below, may result in injury by electrical shock, a fire and/or serious injury.

•  It is not recommended to use this power tool for work activities such as polishing. Performing work tasks for which this power tool is not intended may lead to risks and cause injuries of persons.

• Accessories that are not expressly designed and recommended by the manufacturer of the power tool must not be used. The simple fact that the accessory can be attached to your power tool does not guarantee its safe operation.

• The nominal speed of accessories must be at least equal to the maximum speed marked on the power tool. Accessories that operate at higher speeds than their nominal speed may break and disintegrate.

• The outer diameter and thickness of the accessory must be within the limits of the nominal range for the given power tool. Inappropriately sized accessories cannot be sufficiently protected or controlled.

• The threaded fastening element on the accessory must correspond to the thread on the spindle of the angle grinder. The clamping hole on accessories that are mounted on flanges, must be suitable for the limiting diameter of the flange. Accessories that do not correspond to the power tool installation dimensions will be unbalanced, may vibrate excessively and may result in loss of control.

• Damaged accessories must not be used. Prior to every use, check the accessories: on grinding discs for chipping and cracking, on support plates for cracks, tears or excessive wear, on steel brushes for loosened or cracked bristles. If the accessory or the power tool were dropped, check it for damage or install undamaged accessories. After checking and installing an accessory, the user and bystanders must stand away from the plane of the rotating accessory, and allow the power tool to run at the highest speed without load for one minute. Damaged accessories will usually break or disintegrate during this test period.

• Personal protective aids must be used. Depending on the level of use, it is necessary to use a face shield or protective glasses or goggles. A dust mask, hearing protection, gloves and work apron capable of stopping small fragments of the abrasive or workpiece must be worn. Eye protection must be able to stop flying fragments that are created during various work activities. A dust mask or respirator must be able to filter out par-ticles created during a given activity. Long term exposure to high intensity noise may result in hearing loss.

• Bystanders must remain at a safe distance from the work area. Everybody that enters the work area must use personal protective work aids. Fragments from the workpiece or damaged accessories may fly out and cause injury also outside the direct vicinity of the work area.

• When performing activities, where the grin-ding tool may come into contact with hidden conduits or its own power cord, the power tool must be held only by the insulated holding surfaces. In the event that the machining tool comes into contact with a „live“ conduit, the uninsulated metal parts of the tool will become live and may result in the user suffering injury by electrical shock.

• The flexible power cord must be located out of range of the rotating power tool. In the event that the user loses control, the flexible power cord could be cut or ground through, and a hand or arm of the user may be pulled into the rotating work tool.

• The power tool must never be put down until the work tool comes to a complete stop. The rotating work tool may catch the surface and rip the power tool out of the user‘s control.

• The power tool must never be started at the side of the user while being carried. In the pace event of accidental contact, the rotating work tool may
  become entangled in the user‘s clothing and pull itself towards the body.

• The vents on the power tool must be cleaned regularly. The motor fan pulls dust into the case and excessive accumulation of metal dust may create an electrical hazard.

• The power tool must not be in the vicinity of flammable materials. These material could catch on fire from emitted sparks.

• Accessories that require cooling with a liquid must not be used. Using water or other cooling liquids may cause injury or death by electrical shock.

OTHER SAFETY INSTRUCTIONS FOR ALL WORK ACTIVITY
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to the clamping or jamming of a rotating disc, support pad, brush or other accessories. Clamping or jamming will cause an abrupt stoppage of the rotating work tool, which will subsequently cause the power tool to uncontrollably move in the opposite direction to the rotation direction of the work tool at the point of jamming.
For example: if the grinding disc is clamped or jammed in a workpiece, the edge of the disc that is entering the clam-ping point may enter the surface of the material and cause the disc to be pushed out upwards or ejected. The disk may jump towards the user or away from the user depending on the rotation direction of the disc at the clamping point. In such cases, grinding discs may also crack.
Kickback results from the incorrect use of the power tool and/or incorrect work procedures or conditions, and can be prevented by properly adhering to the safety measures specified below.

• The power tool needs to be held firmly and a correct body and hand posture must be maintained to resist kickback forces. The auxiliary handle must always be used if the power tool is equipped with it in order to ensure maximum control over kickback or reaction torque when the power tool is started. The user is able to control the reaction torque and kickback forces if they adhere to the correct safety measures.
• Hands must never come close to a rotating work tool. The kickback of a power tool may fling away the user‘s hand.
• One must not stand in the location, where the power tool would travel in the event of kickback. Kickback will fling the power tool in the opposite direction to the disc‘s movement direction at the jamming point.
• It is necessary to pay special attention when machining corners, sharp edges, etc. It is necessary to prevent the work tool from jumping and jamming. Corners, sharp edges or jumping have a tendency to jam the rotating work tool and cause loss of control or kickback.
• It is forbidden to attach a saw chain woodcarving disc or saw disc with teeth to the power tool. These saw blades very often cause kickback and loss of control.

ADDITIONAL SAFETY INSTRUCTIONS FOR GRINDING AND CUTTING WORK TASKS

SAFETY WARNINGS
SPECIFIC TO GRINDING, SANDING AND ABRASIVE CUTTING WORK TASKS:

• Use only the type of discs that are recommended for this power tool and the specific guard that is designed for the selected disc. Discs for which the power tool was not designed cannot be cove-red in the appropriate manner and are dangerous.
• The grinding surface of discs that are lowered in the middle, must be installed below the level of the guard‘s edge. An incorrectly installed disc that extends past the level of the protective guard‘s edge cannot be sufficiently protected.
• The guard must be safely attached to the power tool and located for maximum safety so that only the smallest part of the disc is uncovered in the direction of the user. The guard helps to protect the user against broken off disc fragments, accidental contact with the disc and sparks that may ignite clothing.
• Discs must only be used for their recommended use. For example: it is not permitted to use the side of a cutting disc. Abrasive cutting discs are intended for peripheral cutting, and lateral forces acting on these discs could fracture them.
• Undamaged disc flanges must always be used, and they must have the correct size and shape for the selected disc. Correct disc flanges support the disc and thereby reduce the risk of the disc cracking. Cutting disc flanges may differ from grinding disc flanges.
• It is forbidden to use worn out discs of originally larger dimensions, that are intended for larger power tools. Discs intended for larger power tools are not suitable for the faster rotation speed of smaller power tools and may crack.

ADDITIONAL SAFETY INSTRUCTIONS FOR CUTTING
ADDITIONAL SAFETY WARNINGS SPECIFIC TO ABRASIVE CUTTING WORK TASKS:

• A cutting disc must not jam inside the material, nor may excessive pressure be exerted on it. One must not attempt to achieve and excessive cutting depth. Overloading the disc increases the load and tendency towards warping or jamming of the disc in the cut and the possibility of kickback or the disc cracking.
• Do not stand along the axis of a rotating disc or behind it. The moment that the disc at the work point is moving away from the body of the user, the possible kickback may thrust the slipping disc and the power tool directly at the user.
• If the disc becomes jammed or the cutting task is for some reason interrupted, the power tool must be turned off and held still until the disc comes to a complete stop. The user must never attempt to pull a cutting disc out of a cut while the disc is moving because kickback could occur. It is necessary to check the situation and remedy it to prevent the possibility of the disc jamming.
• Cutting must not be restarted inside the workpiece. The disc is allowed to reach full speed and is then again plunged into the cut. If the power tool is restarted with the disc still plunged inside the cut, it may jam, it may be pushed upwards or kick-back may result.
• Panels and other large workpieces need to be supported from underneath to reduce the risk of jamming the disc and kickback. Large workpieces have a tendency to buckle under their own weight. Supports must be placed underneath the workpiece near the cutting line and near the edges on both sides of the disc.
• It is necessary to pay special attention when „cutting into a cavity“ on existing walls or other blind areas. The penetrating disc may cut gas or water pipes, electrical conduits or items that may cause kickback.

ADDITIONAL SAFETY INSTRUCTIONS FOR PLANAR SANDING/GRINDING WORK TASKS

SAFETY WARNINGS SPECIFIC
TO WORK ACTIVITY RELATED TO PLANAR SANDING/GRINDING:

• An excessively large sandpaper is not used with the sanding plate. When selecting a sandpaper, it is necessary to follow the manufacturer‘s recommendations. A large sandpaper that extends past the perimeter of the sanding plate risks tearing and may cause jamming, tearing of the disc or kickback.

ADDITIONAL SAFETY INSTRUCTIONS FOR WIRE BRUSH GRINDING WORK TASKS

SAFETY WARNINGS SPECIFIC
TO WIRE BRUSH GRINDING WORK TASKS:

• Even during standard activity, wire bristles are Rejected from the brush. The wires must not be overloaded by excessive pressure on the brush.
  Wire bristles can easily penetrate through light clothing and/or skin.

• In the event that the use of a guard is recommended for use with the wire brush, ensure that there is no contact between the wire disc or brush and the guard. The wire disc or brush may during work due to the effect of load and centrifugal forces increase its diameter.

The cordless power tool creates an electromagnetic field during operation, which may negatively affect the operation of active or passive medical implants (pace event makers) and threaten the life of the user. Prior to using this power tool, ask a doctor or the manufacturer of the implant, whether you may work with this power tool.

• Do not use the cordless power tool for a purpose other than that for which it was designed. Do not modify the saw for different applications.
• When using the cordless power tool, use certified eye and ear protection and gloves with a sufficient level of protection, and when cutting materials during which dust is generated, also protection of the respiratory tract (consult the necessary level of protection at a personal protective aids store). Inhalation of dust is damaging to health.

Safety instructions for the charger

• Read the user‘s manual before charging.
• The charger is intended only for charging indoors. It is necessary to protect it against rain, high humidity and temperatures over 40°C.
• Prevent the charger from being used by persons (including children) whose physical, sensory or mental disability or incapacity or insufficient experience or knowledge prevents them from safely using the appliance without supervision or instruction. Children must not play with the appliance. It is generally not assumed that the charger will be used by very small children (age 0- 3 years inclusive) and used by small children without supervision (age between 3 and 8 years). It is conceded that seriously handicapped persons may have needs outside the level specified by this norm (EN 60335).
• When charging, provide for ventilation since fumes maybe released from the battery if it is damaged as a result of incorrect handling.
• Charge the battery at temperatures in the range 10°C to 40°C.
• Protect the charger and its power cord against damage. Protect the charger‘s charging terminals against conductive bridging when the charger is under voltage, otherwise there is a risk of short circuiting. Protect the plug of the power cord against deformation or other
  types of damage.
