General safety warnings for power tools

WARNING! Read all safety warnings, instructions, illustrations and specifications supplied with this power tool. Failure to follow all of the instructions below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or to your battery-operated (cordless) power tool.

1. Workplace safety
   a) Keep the workplace clean and well lit. Cluttered or dark areas invite accidents.
   b) Do not use power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dusts. Power tools create sparks which may ignite the dust or fumes.
   c) Keep children and bystanders away when operating a power tool. Distractions can cause you to lose control.

2. Electrical safety
   a) The plugs of the power tools must match those of the socket. Do not modify the plug in any way. Do not use adapters with grounded power tools. Non- adapted plugs and appropriate sockets reduce the risk of electric shock.
   b) Avoid physical contact with earthed or grounded surfaces, such as pipes, radiators, cookers and refrigerators. There is an increased risk of electric shock if your body is grounded.
   c) Do not expose electrical appliances to rain or wet conditions. If water gets into an electrical appliance, the risk of electric shock increases.
   d) Do not misuse the power cord. Never use the cord to carry, pull or disconnect the power tool. Keep the cord away from heat, oil, sharp edges or moving parts. Damaged or tangled cords increase the risk of electric shock.
   e) When using an electrical appliance outdoors, use an extension cord suitable for outdoor use. Using a cord suitable for outdoor use reduces the risk of electric shock.
   f) If the use of an electrical appliance in a damp environment is unavoidable, use a power supply with a residual current device (RCD). The use of an RCD reduces the risk of electric shock.
   NOTE: The term “residual current device (RCD)” may be replaced by the term “residual current device (GFCI)” or “residual current device (ELCB)”.

3. Personal safety
   a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool if you are tired or under the influence of drugs, alcohol or medication. A moment’s inattention while operating a power tool can lead to serious personal injury.
   b) Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, safety shoes with non-slip soles, a helmet or hearing protection used under the right conditions will reduce personal injuries.
   c) Prevent unintentional starting. Make sure that the switch is in the off position before connecting the unit to the power source and/or battery, picking it up or carrying it. Carrying power tools with your finger on the switch or energizing power tools with the switch on invites accidents.
   d) Remove any spanner or key before turning on the power tool. If a key or spanner gets stuck on a rotating part of the electrical device, this may cause personal injury.
   e) Do not overextend yourself. Stand firmly and keep your balance at all times. This allows for better control of the power tool in unexpected situations.
   f) Correct clothing. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothing, jewellery or long hair can get caught in moving parts.
   g) If there are facilities for the connection of dust extraction and collection equipment, ensure that they are connected and used correctly. The use of dust extraction can reduce dust-related hazards.
   h) Do not become complacent with the frequent use of tools and ignore the safety principles. A careless act can cause serious injury within a fraction of a second.

4. Use and care of power tools
   a) Do not force the power tool. Use the correct power tool for your application. The right electrical device will do the job better and safer at the speed it is designed for.
   b) Do not use the power tool if it cannot be switched on and off with the switch. Any electrical device that cannot be operated with the switch is dangerous and must be repaired.
   c) Unplug the power cord and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories or storing the power tool. Such preventive safety measures reduce the risk of the electrical device being started accidentally.
   d) Store unused power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
   e) Maintenance of electrical tools and accessories. Check that moving parts are not misaligned or stuck, that parts are broken and that there are no other conditions that could affect the power tool’s operation. If the power tool is damaged, have it repaired before you use it. Many accidents are caused by poorly maintained power tools.
   f) Keep the cutting tool sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to jam and are easier to control.
   g) Use the power tool, accessories and tool bits etc. in accordance with these operating instructions, taking into account the working conditions and the work to be done. Using the power tool for work other than that intended can lead to dangerous situations.
   h) Keep handles and gripping surfaces dry, clean and free of oil and grease. Smooth handles and gripping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5. Use and care of battery-powered tools
   a) Charge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery can pose a fire hazard when used with another type of battery.
   b) Only use power tools with batteries intended for that purpose. The use of other batteries may pose a risk of injury and fire.
   c) When the battery pack is not in use, keep it away from other metal objects, such as paper clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to another. Short-circuiting the battery terminals can cause burns or fires.
   d) Under extreme conditions, liquid may come out of the battery; avoid contact. If it comes in contact with the battery accidentally, flush with water. If the liquid gets into the eyes, seek medical attention immediately. Liquid coming from the battery may cause irritation or burns.
   e) Do not use batteries or tools that are damaged or modified. Damaged or modified batteries may behave unpredictably, leading to fire, explosion or risk of injury.
   f) Do not expose a battery or a tool to fire or excessive heat. Exposure to fire or a temperature above 130 °C may cause an explosion.
   NOTE: The temperature “130 °C” can be replaced by the temperature “265 °F”.
   g) Follow all charging instructions and do not charge the battery or tool outside the temperature range specified in the instructions. Incorrect charging or charging at temperatures outside the specified range can damage the battery and increase the risk of fire.

6. Service
   a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This ensures that the safety of the electrical device is maintained.
   b) Never service damaged batteries. Servicing of batteries may only be carried out by the manufacturer or by authorised service companies.

Additional safety requirements for cordless drills

1. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.

2. Hold the power tool by its insulated gripping surfaces when performing any operation in which the cutting tool may come into contact with concealed wiring. Cutting tools that come into contact with a “live” wire can make exposed metal parts of the power tool “live” and give the user an electric shock.

3. If possible, always use clamps or a vice to hold your work.

4. Always switch off the device before putting it down.

5. Provide sufficient lighting.

6. Do not apply pressure to the tool so that the motor slows down. Let the bit screw without pressure. You will get better results and take better care of your tools.

7. Keep the area free from tripping hazards

8. Only use accessory bits that are in good condition.

9. Before you start, check that there is enough room for the bit under the workpiece.

10. Do not touch the bit after use. It will be very hot.

11. Keep your hands away from under the workpiece.

12. Never use your hands to remove dust, chips or debris near the bit.

13. Rags, cloths, ropes and the like must never be left around the work area.

14. Support the work properly.

15. If you are interrupted while operating the tool, end the process and switch it off before looking up.

16. Check regularly that all nuts, bolts and other fasteners are tight.

17. Use safety equipment, including safety glasses or shields, hearing protection and protective clothing, including protective gloves, when using the tools. Wear a dust mask if dust is generated during machining.

18. WARNING Some substances released during sanding, sawing, grinding, drilling and other construction activities contain chemicals that are known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
    – lead from lead-based paints,
    – crystalline silica from bricks and cement and other masonry products, and
    – arsenic and chromium from chemically treated lumber.
    Your risk from these exposures will vary depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a wellventilated area and use approved safety equipment, such as dust masks specially designed to filter out microscopic particles.

19. Even if the tool is used properly, it is not possible to exclude all residual risk factors. The following hazards may occur due to the construction and design of the tool:
    • Damage to the lungs if an effective dust mask is not worn.
    • Damage to hearing if effective hearing protection is not worn.

Information on noise/vibration
Measured noise values determined in accordance with EN 62841.
Wear ear protection!
Total vibration values (triax vector sum) determined according to EN 62841:
The vibration emission level given in this information sheet has been measured according to a standardised test given in EN 62841 and can be used to compare one tool with another.
It may be used for a preliminary assessment of exposure.
The vibration emission level indicated represents the main applications of the tool.
However, if the tool is used for different applications, with different accessories or is poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
When estimating the level of exposure to vibration, the times when the tool is switched off or when the tool is operating but not actually carrying out the work must also be taken into account. This can significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration, such as: maintaining the tool and accessories, keeping hands warm, organising work patterns.
Suggestions to reduce the risk of vibrations:

1. Wear a glove during use
2. Reduce the operating time and shorten the trigger time.

About the charger
Disconnect the power supply before connecting or disconnecting the battery
The charger must only be used with a rechargeable battery. Never use a nonrechargeable battery.
Do not expose the charger to rain or water
Inserting and removing the rechargeable battery
Insert the rechargeable battery into the device, paying attention to the correct orientation between the battery and the battery compartment. Do not apply force when inserting the battery. The battery can be inserted easily and without resistance. The battery must be fully inserted until the battery retaining clips on the sides of the battery compartment automatically lock the battery in place. To remove the battery, press down on the battery retaining clamps and pull the battery out of the compartment.
Inserting the Tool
Important! Always remove the battery pack before changing the drill or screwdriver bit to prevent the machine from starting unintentionally.
The cordless drill has a keyless chuck so that you do not need a spanner to secure the tool bit. Make sure that the drill or screwdriver bit is not slanted when it is inserted and the drill chuck is tightened.
Before inserting drill/screw bits, open the chuck jaws by holding the lower ring of the chuck and turning the locking ring anti-clockwise.
Open the chuck until you can insert the tool. Hold it and then turn clockwise to secure it.
To remove the tool, hold the machine and turn the chuck anti-clockwise.
Open the chuck until you can remove the tool.
On/Off trigger
Use the on/off trigger to start the machine and hold it down for continuous operation.
The rotation speed can be varied by pressing the power trigger. The more the trigger is pulled, the faster the rotation speed.
Release the power trigger to turn the machine off.
Reverse rotation lever
Important! The machine must come to a complete stop before the reverse rotation lever can be used; otherwise, the machine may be damaged.
Use the reverse rotation lever to switch between right (normal) and left (reverse) rotation or vice versa. If the shuttle lever is in the centre position, the tractor is locked and cannot be pulled. Move the shuttle lever to the centre position before putting the machine down to prevent unintentional starting.
Torque setting
The tool offers 20+1 different torque steps, you can regulate the maximum torque applied to the drill with the torque control knob.
Attention! The torque control knob should only be operated when the machine is not running; otherwise the machine may be damaged.
To set the drill to the lowest torque setting available, turn the torque control knob until the small arrow on the drill body points to the “1” stamped on the torque control knob.
In this position, the clutch will slip with light drilling resistance. The higher the number indicated by the arrow on the torque control knob, the greater the maximum torque that can be applied before the torque clutch slips.
To set the machine to the maximum torque available, turn the torque control knob until the arrow points to the drill symbol. In this position there is no slippage in the torque clutch.
Select a lower torque for inserting/removing screws to avoid damage to the workpiece (especially wooden workpieces) or to the screw. For drilling, select a higher torque. First carry out a test on an object that is not your final workpiece and adjust the desired torque accordingly before starting the actual work.

Operation for work
Use only tool bits that can be fixed firmly in the drill chuck and for which the drill is designed.

1. Drilling
   Check that the drill is correctly positioned and secured before starting the machine. Use well-sharpened drill bits. Select a lower speed at the beginning of each drilling operation. For large holes, first drill with a smaller drill and then enlarge the hole with a larger drill.

2. Drilling in wood
   Use a wood drill for drilling into wood. Protect or secure the workpiece in a suitable holder. Mark the positions of the holes to be drilled with a sharp tool or nail. Do not exert excessive pressure on the workpiece with the machine.

3. Drilling in metal
   Use a steel drill for drilling into metal. Always ensure sufficient cooling with suitable non-flammable coolants. Protect or secure the workpiece with a suitable holder. The workpiece must lie flat on the workbench. Mark the positions of the holes to be drilled with a centre punch. Do not exert excessive pressure on the workpiece with the machine. Let the drill run at its normal operating speed.
   Important! When starting to drill, select a lower speed to prevent the drill from slipping away from the desired position in the hole. If the drill hole is deep, the drill may become stuck in the hole. In this case, a high torque may damage the drill bit. If the drill becomes stuck, hold the machine firmly and release the on/off trigger immediately. Switch to counter clockwise rotation and use a low speed to make it easier to remove the jammed drill bit.

4. Drilling in plastic
   When drilling into plastic, use a steel drill bit and follow the same instructions as for drilling into wood.

5. Using the drill as a screwdriver
   Before using the machine, check that the screwdriver bit is correctly inserted. Do not over-tighten screws, otherwise the screw head may be damaged or the thread stripped. Use screwdriver bits that are not too worn.

6. Insertion of the screw
   Set the direction of rotation of the drill in a clockwise direction. Insert the screwdriver bit into the slot in the head of the screw. Hold the screwdriver bit perpendicular to the head of the screw, otherwise the screw or the screw head may be damaged. Press the screwdriver bit against the screw with constant pressure while driving the screw.

7. Unscrewing the screw
   Set the direction of rotation of the drill to counter clockwise. Insert the screwdriver bit into the slot in the head of the screw. Hold the screwdriver bit perpendicular to the screw head, otherwise the screw or the screw head may be damaged. Press the screwdriver bit against the screw with constant pressure while you are removing the screw.
