GENERAL SAFETY INSTRUCTIONS FOR POWER TOOLS

WARNING! All safety instructions, user manuals, images and regulations supplied with these tools must be read. Failure to follow all of the following instructions may result in electric shock, fire, and/or serious personal injury. All instructions and the user manual must be kept for future reference.

Safety of working environment

1. The workplace must be kept clean and well lit. Untidy and dark spaces are often the cause of accidents.
2. Power tools must not be used in potentially explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks that can ignite dust or fumes.
3. Children and other persons must be kept away when using power tools. If the operator is disturbed, he/she may lose control of the operation.

Electrical safety

1. The plug on the power tool’s flexible lead must match the power outlet. The plug must neverbe modified in any way. No socket adapters may be used with tools that have a protective earth connection. Plugs and respective sockets that are rendered unusable will reduce the risk of electric shock.
2. The operator must not touch grounded objects, such as pipes, central heating units, cookers and refrigerators. The risk of electric shock is greater if your body is connected to the ground.
3. Power tools must not be exposed to rain, moisture or wetness. If water enters the power tool, the risk of electric shock increases.
4. The flexible supply must not be used for other purposes. The power tool must not be carried or pulled by the cord, nor must the plug be unplugged from the socket. The inlet must be protected from heat, grease, sharp edges or moving parts. Damaged or tangled leads increase the risk of electric shock.
5. If the power tool is used outdoors, an extension cord suitable for outdoor use must be used. Using an extension cord for outdoor use reduces the risk of electric shock.
6. If the power tool is used in a humid environment, a residual current device (RCD) must be used. Using an RCD reduces the risk of electric shock.

SAFETY INSTRUCTIONS

Safety of persons

1. When using a power tool, the operator must be careful, pay attention to what he/she is doing, and concentrate and think clearly. Power tools must not be used if the operator is tired or under the influence of drugs, alcohol or medication. Momentary inattention while using a power tool can result in serious personal injury.

2. Use personal protective equipment. Always use eye protection. Protective equipment such as a respirator, non-slip safety shoes, hard hat and hearing protection, used in accordance with the working conditions, reduces the risk of
   personal injury.

3. Unintentional starting of the machine must be avoided. Make sure that the switch is in the off position before plugging in and/or connecting the battery pack, lifting or carrying the tool. Carrying a tool with your finger on the switch or plugging in a tool fork with the switch on can cause injury.

4. All adjusting tools or wrenches must be removed before turning on the tool. An adjusting tool or wrench that remains attached to the rotating part of the power tool may result in personal injury.

5. The operator must only work where he/she can safely reach. The operator must always maintain a stable posture and balance. This will allow better control of the power tool in unforeseen situations.

6. Dress appropriately. Do not wear loose clothing or jewellery. The operator must make sure that his/her hair and clothing are a sufficient distance away from moving parts. Loose clothing, jewellery and long hair can be caught in moving parts.

7. Where equipment is provided for connecting dust extraction and collection facilities, care must be taken to ensure that it is connected and used correctly. The use of such equipment can reduce hazards caused by dust.

8. The operator must not allow the routine that results from the frequent use of the tools, to cause them to become complacent and ignore the principles of tool safety. Careless activity can cause serious injuries in a split second.

Use and the maintenance of power tools

1. Power tools must not be overloaded. It is essential to use the correct power tool for the work being carried out. The correct power tool will do the work it was designed to do better and safer.
2. Power tools that cannot be turned on and off with the switch must not be used. Any power tool that cannot be operated with the switch is dangerous and must be repaired.
3. Before making any adjustments, changing accessories, or storing power tools, unplug the power tool and/or remove the battery pack from the power tool if it is removable. These precautions reduce the risk of accidentally starting the power tool.
4. Unused power tools must be stored out of the reach of children. Persons unfamiliar with the power tool or these instructions must not be allowed to use the power tool. Power tools are dangerous in the hands of inexperienced users.
5. Power tools and accessories must be maintained. The adjustment of moving parts and their mobility must be checked and attention focused on cracks, broken parts and any other circumstances that may jeopardize the function of the power tool. If the tool is damaged, it must be repaired before use. Many accidents are caused by poorly maintained power tools.
6. Cutting tools must be kept sharp and clean. Properly maintained and sharpened cutting tools are less likely to catch on material or jam and are easier to control.
7. Power tools, accessories and tool bits etc. must be used in accordance with these instructions and in the manner intended for the particular power tool, taking into account the working conditions and the work to be carried out. Using power tools for activities other than those for which they are designed can lead to dangerous situations.
8. Handles and grip surfaces must be kept dry, clean and free of grease. Slippery handles and gripping surfaces mean the tool cannot be held and controlled in unexpected situations.

Service

1. Power tool repairs must be carried out by qualified personnel using identical spare parts. This will ensure the same level of safety of the power tool as before the repair.

USE AND MAINTENANCE OF CORDLESS TOOLS

1. The tool must only be charged with the charger specified by the manufacturer. A charger that may be suitable for one type of battery pack may present a fire hazard when used with another battery pack.
2. The tool must only be used with a battery pack that is specifically designed for the tool. The use of any other battery pack may present a risk of injury or fire.
3. When the battery set is not used, the battery pack must be protected from contact with other metal objects, such as paper clips, coins, keys, nails, screws or other small metal objects that can cause one battery contact to come into contact with another. Short-circuiting the battery terminals may cause burns or fire.

Safety instructions for all work activities

1. Hearing protection must be worn when hammer drilling. Noise exposure can cause hearing loss.
2. Additional handle(s) must be used. Loss of control can cause personal injury.
3. The tool must be fully secured before use. This tool produces a high output torque and without proper locking against the tool during operation, loss of control may occur, which may result in personal injury.
4. When performing an operation where the drilling tool may touch a hidden guide or its own power supply, the power tool must be held by the insulated gripping surfaces. Contact of the drilling tool with a “live” wire can cause the uninsulated metal parts of the power tool to become “live” and lead to an electric shock to the user.

Safety instructions when using long drills

1. Never use the machine at speeds higher than the maximum rated drill speed. At higher speeds, the drill is likely to bend if it is allowed to rotate freely without being in contact with the workpiece, which can result in personal injury.
2. Always start at a low speed with the tip of the drill touching the workpiece. At higher speeds, the drill is likely to bend if it is allowed to rotate freely without being in contact with the workpiece, which can result in personal injury.
3. Only push in a straight line with the drill and do not apply excessive ressure. Drills can bend and crack or cause loss of control, which can result in personal injury.

DRILL PREPARATION

BATTERY CHARGE STATUS
You can check the current battery charge by pressing the battery indicator button.

TIPS FOR EFFICIENT BATTERY USE

• Charge the batteries before they are completely discharged.
• If the performance of the machine decreases, stop using it and replace or charge the battery. Using the machine with the last remaining battery power may damage the battery.
• Do not charge the batteries at high temperatures. The batteries are hot immediately after use. When such a battery is charged, the chemical structure of the cells degrades, and the battery life is shortened. Therefore, allow the batteries to cool before charging.
• The batteries can only be charged and used in the temperature range of 5 ° C to 30 °C. There is a risk of damage to the cells. Always allow the batteries to reach normal temperature.
  Note: Failure to follow these instructions can damage the batteries and charger or cause an injury

BASIC USE

FIXING AND REMOVING THE DRILL

Note: The product is equipped with an electric brake. The drill is equipped with a chuck, which allows the drill to be fixed without using tools. No handles are needed to fasten and loosen the drill or screwdriver bits.

• Insert the drill bit into the chuck hole as deep as possible.
• Firmly tighten the chuck by hand. Note: Simply insert the short screwdriver bits between the jaws.

ROTATION DIRECTION SELECTION

REVERSE, FORWARD
The direction of rotation switch (7) allows you to change the direction of the rotation of the spindle.

Change direction of rotation:

• Stop the engine and press button (7) left or right.
• When the switch is pressed to the left, the drill rotates to the right (forward).
• When the switch is pressed to the right, the drill rotates to the left (backwards).
• Always make sure the switch is in the correct position before use. The direction cannot be changed while the machine is running; always wait for the drill to come to a complete stop.
• When not in use, you can set the direction switch to the neutral position (centre) when the motor switch is locked.
  Note: If the switch is not in the neutral position, the switch may be accidentally pressed, and the drill switched on accidentally. Doing so may damage the machine or cause injury

SPEED CONTROL SWITCH
When the switch (2) is pressed, the drill spindle rotates (assuming the direction selector (7) is in one of the extreme positions). This switch is also used to continuously control the rotation speed electronically.

• The speed of rotation depends on the degree to which the switch button is pressed.
• The deeper it is pressed, the faster the drill rotates.
• When pressed lightly, the spindle rotates more slowly.

TORQUE CHOICE
By turning the ring (9) around the chuck, it is possible to set the maximum torque that the machinewill reach.

• Setting 1-25 allows you to select the maximum torque. This is suitable, for example, for repeatedly screwing identical screws, which are tightened with the same force after setting the torque and, in the case of countersunk screws, are equally deep in the material.
• If the torque is set correctly, the small diameter screw will not break.

TWO-SPEED GEARBOX

• Choose lower gear 1 (lower speed and higher torque) for screwdriving and large drill diameters.
• Use higher gear 2 (higher speed and less force) for drilling holes.

BELT CLIP
The spring-clip (6) for hanging on the belt is used to temporarily hang the drill. The clip can be attached on both sides of the drill.

Clip installation:

• Adjust the clip (6) to the appropriate position and secure it with the enclosed screw. Tighten the screw carefully so as not to tear the thread in the machine.

LED LIGHT
The light (4) comes on automatically when the drill switch is pressed and makes it easier to work in tight and poorly lit areas.

SCREWING
Choose the size and type of screwdriver bit according to the screw head to prevent the tool from slipping or damaging the head.

Removing a screw:

• Slide the direction switch to the left rotation position and slowly press the switch while applying pressure to the screw. Screwdriver bits are consumables

Warning!

• Before drilling, make sure that dangerous objects, such as gas, water and electricity lines, etc., are not hidden under the material being drilled. Check with a suitable detector.
• Do not expose the drill or tool charger to rain or moisture.
• Do not overcharge the battery (for more than 6 hours), as this may damage the cells.

WOOD AND PLASTIC DRILLING
To prevent the edges of the hole from fraying on the underside of the material, underlay it with a piece of the same material at the location of the future hole.

METAL DRILLING
It is possible to drill metals such as mild steel and non-ferrous metals. Some tips are useful.

• Mark the centre of the hole with a punch so that the drill does not slip
• A drop of oil at the location of the future hole will facilitate drilling and extend the life of the drill.

Note: Although metal drilling is within the capabilities of this drill, the rotation speed may not be suitable for all applications and provide the best result. Take extra care when drilling into metal, there is a risk of various complications.

MAINTENANCE
Regular inspections and cleaning of the machine reduce the need for service and keep the machine in good condition. The engine must be sufficiently cooled during operation. Keep the air vents clean and regularly dusted.

TROUBLESHOOTING

Note: Remove the battery from the drill before adjustment and maintenance.
