GENERAL SAFETY CONDITIONS
NOTE! Get acquainted with all the instructions below. Failure to observe
them may lead to an electric shock, fire or injuries. The notion of electric
tool used in the instructions applies to all the tools which are powered with
electric current, both wire tools and
wireless ones.
OBSERVE THE FOLLOWING INSTRUCTIONS
Place of work
The place of work must be properly illuminated and clean. Disorder and poor
illumination may be a cause of accidents.
Do not work with electric tools in explosive environments, or those which
contain infl ammable liquids, gases or vapours.
Electric tools generate sparks, which may cause a fi re in case of contact with
infl ammable gases or vapours.
Do not allow children and outsiders to the place of work. A lack of
concentration may result in a loss of control over the tool.
Electric safety
The plug of the power supply cable must fi t the mains socket. Do not modify
the plug. Do not use any adapters whatsoever in order to adapt the plug to the
socket.
Unmodified plug which fits the socket reduces the risk of an electric shock.
Avoid contact with grounded surfaces, such as pipes, heaters and
refrigerators. Grounding of the body increases the risk of an electric shock.
Do not expose electric tools to precipitation or humidity.
Water and humidity which gets into the electric tool increases the risk of an
electric shock.
Do not overload the power supply cable. Do not use the power supply cable in
order to carry the tool or to connect and disconnect the plug from the mains
socket.
Avoid contact of the power supply cable with heat, oils, sharp tools and
moving elements. Damage to the power supply cable increases the risk of an
electric shock.
In case work is realised outside closed areas, it is necessary to use
extension cords designed for applications outside closed areas. Using a
correct extension cord permits to reduce the risk of an electric shock.
If operating a power tool in a damp location is unavoidable, use a residual
current device (RDC) protected supply. Use of an RCD reduces the risk of
electric shock.
Personal safety
Commence work in good physical and psychological conditions. Pay attention to
what you do. Do not work if you are tired or under eff ects of medicines or
alcohol. Even a moment’s inattention during work may lead to serious injuries.
Always use individual means of protection. Always wear goggles. Using
individual means of protection, such as dust-masks, protective shoes, helmets
and hearing protections permits to reduce the risk of serious injuries.
Avoid accidental activation of the tool. Make sure the switch is in the OFF
position, before you connect the tool to the mains. Holding the tool with a fi
nger on the switch or connecting an electric tool when the switch is in the ON
position may lead to serious injuries.
Before you turn an electric tool on remove all the spanners and other tools,
which have been used for adjustments. A spanner left on rotating elements of
the tool may lead to serious injuries.
Keep your balance. Maintain an appropriate position. It will permit to control
the electric tool in case of unpredicted situations during its operation.
Use protective clothes. Do not wear loose clothes or jewellery. Keep your
hair, clothes and gloves away from moving elements of the electric tool. Loose
clothes, jewellery or long hair may get caught on moving elements of the tool.
Use dust extractors or dust containers, if the tool is equipped with any. Make
sure they are properly connected. Using of dust extractors permits to reduce
the risk of serious injuries.
Safety precautions while using the electric tool
Before the battery is installed, make sure the switch is off . Installation of
the battery when the switch is on may lead to accidents.
Use solely the charger recommended by the manufacturer. Using a charger
designed for another type of battery may be a cause of fire.
The electric tool must be operated exclusively with the battery indicated by
the manufacturer. Using another battery may be a cause of fire or injuries.
When the battery is not used, it must be stored away from such metal objects
as paper clips, coins, nails, screws or other small metal elements, which
might short-circuit the terminals. Short-circuited terminals of the battery
may cause burns or fire.
Under adverse circumstances liquid may leak from the battery; avoid any
contact. In case of accidental contact with the liquid, rinse it with water.
In case of eye contact, seek medical. The liquid leaking from the battery may
cause irritation or burns.
During work when the tool may touch a hidden live conductor, the electric tool
must be held by insulated handles. The installed bit in case of contact with a
live conductor may conduct electricity to the metal elements of the tool,
which may cause electric shock to the operator.
Repairs
The tool may be repaired only by authorised service centres, which must use
solely original spare parts. It will guarantee a proper level of safety of
operation of the electric tool.
ADDITIONAL SAFETY INSTRUCTIONS
The tool has been designed exclusively for grinding, grinding with abrasive
paper, grinding with wire brushes and cutting. 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 polishing 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.
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 infl ammable 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
fl icking 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 grinding and cutting with abrasive disks
Use only disks which are adequate for the tool and guards designed for the
given type of disk. Disks which are not compatible with the tool cannot be
properly protected and are not safe.
The grinding surface of centre depressed wheels must be mounted below the
plane of the guard lip. An improperly mounted wheel that projects through the
plane of the guard lip cannot be adequately protected.
The guard must be secured to the tool and placed in a position which ensures
maximum safety, so that the smallest possible area of the disk is unprotected
towards the operator. The guard helps to protect the operator from broken
fragments of the disk and prevents accidental contact with the disk.
The disk must be used as intended. For example: do not grind with disks
designed for cutting. Abrasive disks for cutting are designed for
circumferential load, and the lateral forces applied to such a disk may
destroy it.
Always use undamaged fi xing disks, whose dimensions must be compatible with
the grinding disk. Adequate fi xing disks for the abrasive disk reduce the risk
of damaging the grinding disk. The fi xing disks for cutting disks may diff er
from the fixing disks designed for grinding disks.
Do not use worn abrasive disks from bigger tools. An abrasive disk of a bigger
diameter is not adapted to a bigger rotational speed of smaller tools and may
break.
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 signifi cantly exceeds the size of the disc may cause injuries and
increases the risk of seizure, tearing or rebounding towards the operator.
Warnings related to work with wire brushes
Be careful, since fragments of wires are ejected from the brush also during
normal work. Do not overload the wires exerting excessive force on the brush.
The wires may easily perforate light clothes and/or the skin.
If it is recommended to use guards while working with wire brushes, preclude
any contact of the brush with the guard.
The diameter of the wire brush may increase due to the load and the
centrifugal force.
PREPARATION FOR WORK
ATTENTION! All the operations mentioned in this point must be realised
with the power supply off.
– the battery must be disconnected from the tool!
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 fi re 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 eff ect”, 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 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.
Charging the battery
Attention! Before charging you should disconnect the charger from the mains by
unplugging the power supply plug from the mains. In addition, you should clean
the battery and its terminals of dirt and dust with a soft, dry cloth.
The battery has a built-in charge indicator. When you press the button, LEDs
will light up (II), the more LEDs will light up, the more fully the battery
pack is charged. If the button is pressed and the LEDs are off it means that
the battery is discharged.
Disconnect the battery from the tool.
Push the battery in the charger socket (II).
Plug the charger into a mains socket.
When the red LED lights up, it means the loading process.
When charging is complete, the red LED goes off , and green LED lights up,
indicating a full charge of the battery.
Unplug the charger from the mains outlet.
Remove the battery from the charging station, by pressing the battery latch
button.
Attention! If, when the charger is connected to the power supply, the
green LED is on, this indicates a fully charged battery. In this case, the
charger does not start charging.
ASSEMBLY OF EQUIPMENT ELEMENTS
Assembly of the abrasive wheel guard
For this purpose, you should put on the wheel cover on the cylindrical body
part around the spindle and with a screw or clip of cover ring clamp,
immobilize it, so the cover will be mounted straight ahead, firmly and tightly.
Set the guard of the grinding wheel,so the unsheltered part of the grinding
wheel will be as far as possible from the hand of a grinder user. Never work
with the grinder without correctly mounted grinding wheel guard!
With the grinder there is supplied the guard, which provides the adequate
protection only when grinding with abrasive wheels and wheels using sandpaper
and some wire brushes. After installing the wheel on the spindle, the
accessory must not protrude beyond
the side guard. In the case of performance of any other type of allowed work,
you should contact the manufacturer to acquire the guard intended for this
kind of work.
Installation of auxiliary handle
Mount the handle by its fi rm screwing to the tool heading. The handle has a
socket, which allows to store the wrench for fi xing the grinding wheel. This
makes it easier to store the wrench. After completion of all works requiring
to use the wrench it should be inserted in the socket and you should make sure
that it does not slip spontaneously by its own weight.
OPERATION OF THE GRINDING WHEELS
ATTENTION! Mounting of the abrasive wheels may be done only with
disconnected power supply. Remove the battery pack from the power tool socket!
Installing the wheels
Disconnect power supply voltage from the tool. Remove the battery pack from
the power tool socket!
During the assembly please pay attention, that the edges A (IV) at the bottom
of the spindle shaft and of the mounting flanges exactly overlap.
Install the top mounting flange on spindle,
Mount the grinding wheel on the spindle and on the upper mounting flange.
Screw the bottom mounting fl ange on the spindle.
Press the spindle lock and tighten the lower mounting flange with a key and
then release the lock button.
Mount the battery to the power tool, turn on the grinder and watch its work
without any load by the time of about 1 minute.
Remove the battery and inspect the wheels mounting.
The location of the mounting flanges
Please pay attention, that grinding wheels, in the point of mounting to the
spindle, can vary in their thickness.
Depending on the applied grinding wheels, which are thin (thickness up to 3.2
mm), or thick (thickness above 3.2 mm) the positioning of mounting flanges
(III) is different. Do not use wheels thicker than 6 mm.
Removing the grinding wheels
Turn off the grinder and remove the battery.
Press the spindle lock and loosen the lower mounting flange with the wrench for
mounting, and then remove the abrasive wheel from the spindle. Clean the
spindle and clamping flanges of dust and other pollutants arising in the course
of work.
Types of abrasive wheels
You can use for grinder all grinding wheels designed for use with angle
grinders with a permissible peripheral speed of at least 80 m/s and fi xing and
external diameters specified in the technical data table.
If the grinding wheel is equipped with an unthreaded hole, for its mounting
you should use the mounting flanges.
It is also possible to mount the grinding wheels with an outside diameter
specified in the technical data table, equipped with a threaded hole M14. In
this case, you should not use the mounting flanges, and the grinding wheel
should be screwed directly to the spindle, by blocking it with a button, and
by tightening the blade firmly and securely with a flat wrench (the grinder is
not equipped with it).
In the case of wheels, which allow for mounting the sandpaper wheel by using
Velcro, you should only use the sandpaper wheels, which are specified in the
table of technical data. The wheels should be placed concentrically on the
grinding wheel. The edge of the wheel should not protrude beyond the wheel
edge.
It is also possible to use diamond grinding wheels with dimensions specifi ed
in the technical data table, intended for cutting and dry grinding.
Installation should be carried out in the same way as for grinding wheels.
For metal treatment it is recommended to use grinding wheels made of materials
intended for the processing of a given type of metal. Refer to the
documentation that is attached to the grinding wheel.
For the processing of ceramic materials you can use the grinding wheel or
diamond grinding wheels, designed for a dry work.
Wire brushes and sanding wheels are recommend for removing old paint coatings
from metal parts.
It is prohibited to modify the mounting hole, spindle or use reduction rings
in order to align the mounting hole diameter to the diameter of spindle. It is
prohibited to use grinding wheels with a mounting diameter other than the
diameter specified in the technical data table. It is forbidden to use wheels
with the cutting chain or disk saws. because that increases the risk of tool
rebound toward the operator.
Attention! It is forbidden to use other grinding wheels than those, which
are approved for use in this manual. Even if they can be mounted on the
grinder spindle. Inappropriate grinding wheels may not withstand the loads
generated during the operation of the angle grinder. Damaged, crumbling
grinding wheels create a threat of serious injury or death.
USE OF THE GRINDER
Remove the battery from the power tool socket!
Before working with the tool, you should check whether the enclosure, cover
and battery are not damaged.
If there are any visible damages it is prohibited to operate the grinder!
Attach the cover of grinding wheel and the handle.
Never work with the grinder without correctly mounted grinding wheel guard!
Choose the type of grinding wheel, which is appropriate for the type of work,
and mount the grinding wheel on the grinder spindle.
Workpiece should be mounted in an appropriate way, so it does not move during
its machining, for example, by clamps or clips.
The wheel of grinder spins at high speed and improper mounting of the
workpiece can cause its uncontrolled movement during operation, which
increases the risk of injury.
In the case of cutting you should support the cut material on both sides of
the cut line, but in such a way, that during cutting it would not cause the
grinding wheel jam. Supports should be positioned near the edges of cut
material, and near the cut line.
Wear eye protection, hearing protectors and working gloves.
Check, whether the switch is in the “off – 0” position. Then connect the
battery to the power tool.
Adopt the proper body position, which is needed to maintain balance, and run
the grinder by its switch.
The switch has a security lock to prevent accidental starting of the grinder.
Move the lock back so it will be at level of the switch surface, and then will
allow to press it. The switch does not have the possibility of blocking in the
ON position, you should hold it all the time during the work.
Proceed to work by applying the proper surface of the grinding wheel to
workpiece:
– in the case of grinding wheels for grinding you should grind by the side
and/or front surface,
– in the case of fl ap grinding wheels you should grind by the surface side so
that the sandpaper leaves would move parallel to the workpiece,
– in the case of wheels with Velcro, which allow for fi xing the abrasive
paper, grinding must be carried out by side surface,
– in the case of wire brushes the treatment should be done by wires endings,
not by their side surface,
– in the case of grinding wheels for cutting, you should cut by their front
surface, do not grind by the front surface of grinding wheels, which are
designed for cutting.
Speed control (VI)
The grinder has speed regulation by means of a rotary regulator. It is
possible to smoothly adjust the speed in the range given in the technical data
table. Use a lower speed for brushes and sandpaper grinding wheels. High speed
should be used for abrasive discs.
When grinding with a side surface you should keep the grinder at an angle of
no more than 30 degrees with respect to the treated surface (VII). Move the
grinder forward and back by smooth moves.
During cutting, the grinding wheel should be at a right angle relative to the
cut surface. Do not make the cut at a diff erent angle. It is forbidden to
change an angle of the cutting grinding wheel in relation to the workpiece
during the cutting operation. The cut should be made only in a straight line.
Failure to follow these guidelines increases the risk of grinding wheel jam in
workpiece, which can cause rebound of tool toward the operator, rupture of the
grinding wheel or its disintegration uring cutting, drive the grinder in the
direction of rotation of the wheel (VIII).
During grinder operation, do not exert too much pressure on the treated
material, and do not make sudden movements, to not cause jamming, or cracks
and bursts of grinding wheel.
Do not allow to overload the grinder, its external surfaces temperature should
never exceed 60 OC.
The grinder is stopped after releasing the pressure on the switch.
At the end of work you should turn off the grinder, remove the battery and make
an examination.
Attention! The grinding wheel can rotate even for some time after the machine
is switched off . You should wait until a complete stop of grinding wheel
movement before putting away the grinder. Prior to the inspection you should
wait for cooling of the grinding wheel. During the work, both, grinding wheel
and workpiece material, can warm up to a high temperature.
Remember! When operating the angle grinder:
Always use eye protection.
Do not use grinding wheels of a maximum allowable peripheral speed of less
than 80 m/s.
Do not use grinding wheels of a maximum allowable rotational speed less than
the rotational speed of the grinder.
The declared, total declared value of vibration was measured by the standard
test method, and it can be applied to compare one tool to another. The
declared, Declared total value of vibration can was used in a preliminary
assessment of exposure.
Attention! The vibration emissions when working with the tool can diff er from
the declared value, depending on how you use the tool.
Attention! You should specify the security measures to protect the operator,
which are based on an assessment of exposure in the actual conditions of
operation (including in it all parts of the work cycle, such as, for example,
the time when the tool is turned off or it is idling, and its activation time).
MAINTENANCE AND OVERHAUL
ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been fi nished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following elements: body and handle, conductor with a plug and defl ection, functioning of the electric switch, patency of ventilation slots, sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee rights. All irregularities detected at overhaul or during functioning of the tools are a signal to have the tool repaired at a service shop. Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or cleaning liquids. Tools and handles must be cleansed with a clean cloth.
