Description – purpose of use

Cordless impact wrench with a high torque of 180 Nm and a hex tang 1/4″, that is a part of the cordless power tool range SHARE 20 V powered using a single type of battery, is intended for tightening and loosening bolts and wood screws in wood, steel and concrete. Impact torque increases the power of the wrench when screwing and is thus far more effective than a cordless drill. Thanks to impact torque it is possible to screw on more bolts per single battery charge

• Thanks to the very slow self-discharge of the Li-ion battery, the impact wrench is ready for use even long after it has been charged. Furthermore, the Li-ion battery can be recharged at any time, regardless of its charge level without reducing its capacity.
• The battery is equipped with protection against full discharge, which damages it. This protection prevents the battery voltage from falling below a certain value that is damaging to it.
• The cordless impact wrench variant Extol® Premium 8891875 is supplied without a battery and charger at a lower purchase price for the situation where the user has already purchased the battery and charger with another cordless power tool from the SHARE 20 V cordless product range.
• The cordless impact wrench variant Extol® Premium 8891874 is supplied with a Li-ion battery 2000 mAh, 20 V and charger 2.4 A.

On charger Extol® Premium 8891892NZ (model with a charging current of 4 A) the charging process is indicated only by a red lit LED indicator light and the fully charged process by only a green lit LED indicator light. The battery charge level can be seen by the number of lit LED indicator lights on the battery, which are lit while the battery is charging. The manufacturer reserves the right to modify the above described indication of the charging and charged process.

APPROXIMATE BATTERY CHARGING TIMES

• e) After charging, first disconnect the charger from the el. power source and then, after pressing and holding down the button on the battery, slide the battery out of the grooves in the charger.

Preparing the impact wrench for use

SETTING THE ROTATION DIRECTION

• For rotation in the direction of the arrow „1“, set the rotation toggle switch on side „1“.
• For rotation in the direction of the arrow „2“, set the rotation toggle switch on side „2“.

INSERTING/EXCHANGING A TOOL PIECE

• Prior to inserting, exchanging tools, maintenance, etc. set the rotation toggle switch (fig. 1, position 3) to the middle position so that the trigger switch (fig. 1, position 8) cannot be accidentally pulled as this could result in injury.

INSERTING A TOOL

• Into the tool tang (fig. 1, position 1), insert the driver bit or driver bit holder with an inserted driver bit all the way in. We recommend using a driver bit holder with a ball retainer for better retention of the tool in the tang. For tightening/loosening nuts, insert a nut adapter with a hex shank into the tang.

• For using the impact wrench with a drill chuck adapter, first insert the hex shank of the chuck adapter into the tang of the impact wrench and then insert the drill bit into the chuck head with the chuck open. Then secure the drill bit in place by closing the chuck. To open/close the chuck on the chuck adapter, grasp the collar of the chuck head and depending on the rotation direction of the tang of the impact wrench the chuck will open/close similarly as on a cordless drill.

EXCHANGING/REMOVING TOOLS FROM THE TANG

• Remove the tool from the tang of the impact wrench.

Starting / regulating speed / activating illumination of the work area

• Start the impact wrench by pulling on the trigger switch (fig. 1, position 8). Pulling the trigger switch will activate the LED diode for illuminating the work area (fig. 1, position 9).
• The speed is regulated by the degree to which the trigger switch is pulled. Percussion is activated in the rotation direction of the tang (not along the direction of the tool‘s axis) when the motor is put under a greater load.

TURNING OFF

• Turn off the impact wrench by releasing the trigger switch.

Using the impact wrench

• Prior to screwing thicker or longer wood screws, particularly into hard materials, pre-drill a hole with a diameter of the core of the thread to 2/3 of the length of the screw. The table below provides the recommended diameter of the pre-drilled hole for the given wood screw diameter.

• Seat the tool in the tang of the impact wrench on to the corresponding wood screw/bolt/nut only while it is not rotating, otherwise the tool could slip.

TIGHTENING TORQUE

• The total tightening torque depends on the duration of the effect of the partial tightening torques. The greatest tightening torque is achieved after approximately 6 to 10 seconds of acting forces. Excessive tightening or the use of poor quality installation elements may result in the installation element being torn off. The current tightening torque can be determined using a torque wrench.

ATTENTION

• Prior to using the tool, it is necessary to lean against the tool with the other hand placed on a wall or pad, whilst maintaining a stable body position. This power tool generates a high output torque and without proper leaning against the tool during operation, loss of control may result, which may lead to injury of persons.

The battery is equipped with protection against full discharge, 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, but then it will stop again.

• In the event that there is an unusual noise, vibrations or operation while it is running, immediately turn off the power tool, remove the battery 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 authorised service centre for the Extol® brand through the merchant or directly at an authorised service centre (service locations are listed at the website address at the start of this manual).

Safety instructions for work with the impact wrench

• When working with the impact wrench, the user and persons in the work area must use certified hearing and eye protection with a sufficient level of protection. The effect of the noise may result in irreparable damage to hearing.
• When working with the impact wrench, the user must wear suitable work gloves.
• If appropriate, always secure the workpiece securely in place.
• When working with the impact wrench, hold it firmly by the handle since during tightening or loosening, high reaction torques may be generated.
• Wait until the tool tang comes to a complete stop before putting down the impact wrench and set the rotation toggle switch to the middle position, this will secure the trigger switch against being accidentally pulled.
• When performing activities, where a fastening element (machining tool) may come into contact with hidden conduits or its own power cord, hold the power tool by the insulated holding surfaces. In the event that the fastening element (machining tool) comes into contact with a „live“ conduit, the uninsulated metal parts of the power tool will become live and may result in the user suffering injury by electrical shock.
• The power tool creates an electromagnetic field during operation, which may negatively affect the operation of active or passive medical implants (pacemakers) 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.

SAFETY INSTRUCTIONS FOR DRILLING (WITH THE USE OF THE CHUCK ADAPTER)

1. Safety instructions for all work activity
   • a) When drilling with percussion, it is necessary to wear hearing protection. Exposure to noise may result in loss of hearing.
   • b) Before using the power tool, it is necessary to properly lean against the power tool. This power tool generates a high output torque and without proper leaning against the tool during operation, loss of control may result, which may lead to injury of persons.
   • c) When performing activities, where the machining tool may come into contact with hidden conduits or its own power cord, hold the power tool 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 electromechanical tool will become live and may result in the user suffering injury by electrical shock.
2. Safety instructions for using long drill bits
   • a) Never use the power tool for higher rotation speeds than the maximum rated rotation speed of the drill bit. At higher rotation speeds, it is probable that the drill bit will bend if allowed to rotate freely without being in contact with a workpiece, which may lead to injuries to persons.
   • b) When starting to drill, it is always necessary to have a low rotation speed and the tip of the drill bit must be in contact with the workpiece. At higher rotation speeds, it is probable that the drill bit will bend if allowed to rotate freely without being in contact with a workpiece, which may lead to injuries to persons.
   • c) It is necessary to push only in the direction of the drill bit and excessive pressure must not be applied. Drill bits may bend and may break or may result in loss of control, which may lead to injuries to persons.

• When drilling into a material during which dust is generated, e.g. when drilling into wood, ensure the extraction of dust from the environment by the use of a suitable industrial vacuum cleaner by placing the vacuum cleaner nozzle to the drilling location and, likewise, by using certified respiratory tract protection with a sufficient level of protection. Inhalation of dust is damaging to health. Do not use a domestic vacuum cleaner for extracting the dust. Likewise, provide for the ventilation of areas where dust is generated.
  Note: The power tool is not intended to be fitted with diamond-crown drill bits.

General safety instructions

WARNING! It is necessary to read all the safety instructions, the user‘s manual, images and regulations supplied with this power tool. Not adhering to any of the following instructions may lead to injury by electrical shock, a fire and/or a serious injury to persons.
All the instructions and the user‘s manual must be kept for possible future reference. The term „power tool“ in all hereafter provided warnings is defined as an tool powered from the power grid (via a power cord) or a tool powered from a battery (without a power cord / cordless).

1. SAFETY IN THE WORK AREA
   • a) The work area needs to be kept clean, tidy, and well lit. Untidiness and dark areas in the work area are sources of accidents.
   • b) The power tool must not be used in environments where there is an explosion hazard, where there are flammable liquids, gases or dust. The power tool generates sparks which could ignite dust or vapours.
   • c) When using the power tool, it is necessary to prevent children and other persons access. If the user becomes distracted, they may lose control over the activity being performed.
2. ELECTRICAL SAFETY
   • a) The plug on the power cord must correspond to the power socket outlet. The power plug must never be modified in anyway. Socket adapters must not be used with power tools that have a safety earth grounding connection. Power plugs that are not damaged by modifications and that correspond to the power socket will limit the danger of injury by electrical shock.
   • b) The user‘s body must not come into contact with grounded objects, such as pipes, central heating radiators, stoves and refrigerators. The risk of injury by electrical shock is greater when your body is in contact with the ground.
   • c) Power tools must never be exposed to rain, moisture or wetness. The entry of water into the power tool increases the danger of injury by electrical shock.
   • d) The flexible power cord must not be used for any other purposes. Power tools must not be carried or pulled by the power cord, nor may the power plug be disconnected by pulling on the power cord. The power cord must be protected against heat, grease, sharp edges or moving parts. Damaged or tangled power cords increase the danger of injury by electrical shock.
   • e) If the power tool is used outdoors, an extension cord suitable for outdoor use must be used. Using extension cords designed for outdoor use, limits the risk of injury by electrical shock.
   • f) If the power tool is used in damp areas, it is necessary to use a power supply protected by a residual current device (RCD). The use of an RCD limits the danger of injury by electrical shock. The term „residual current device (RCD)“ may be substituted for by the term „ground fault circuit interrupter (GFCI)“ or „earth leakage circuit breaker (ELCB)“.
3. SAFETY OF PEOPLE
   • a) When using the power tool, the user must be attentive and pay attention to what they are currently doing and must concentrate and use common sense. The power tool must not be used when the user is tired or under the influence of drugs, alcohol or medication. Momentary inattentiveness when using the power tool may result in serious injury to persons.
   • b) Use personal protective aids. Always wear eye protection. Use protective aids, such as a respirator, safety footwear with anti-slip soles, hard head cover or hearing protection appropriately to the work conditions; they reduce the risk of injury to persons.
   • c) It is essential to avoid accidentally starting the power tool. It is necessary to check that the trigger is in the Off position before plugging the power plug into a power socket and/or when connecting the battery pack, lifting or carrying the power tool. Carrying the power tool with a finger on the trigger or connecting the power tool‘s plug with the switch engaged may cause an accident.
   • d) It is necessary to remove all adjustment tools and spanners before turning on the power tool. An adjustment tool or spanner left attached to a rotating part of the power tool may result in injury to persons.
   • e) The user may only work in locations that they can reach safely. The user must always maintain a stable stance and balance. This will provide better control over the power tool in unforeseeable situations.
   • f) Dress in an appropriate manner. Do not wear loose clothing or jewellery. The user must ensure that they have hair and clothing at a sufficient distance from moving parts. Loose clothing, jewellery and long hair may become caught in the moving parts.
   • g) If there is equipment available for the extraction and collection of dust, it is necessary that such equipment is connected and used correctly. The use of such equipment may limit the danger posed by the created dust.
   • h) The user must not become complacent and start ignoring the fundamentals of power tool safety due to the routine arising from frequent use of the power tool. Careless activity may cause serious injury within a fraction of a second.
4. OPERATING AND MAINTAINING POWER TOOLS
   • a) Power tools must not be overloaded. It is necessary to use power tools that are designed for the work being performed. Appropriate power tools for a given task will do the job better and with greater safety.
   • b) Power tools that cannot be turned on and off with a trigger/switch must not be used. Any power tools that cannot be controlled using a trigger/ switch are dangerous and must be repaired.
   • c) Before making any adjustments, replacing accessories or before storing the power tool, it is necessary to pull the power plug out of the power socket and/or remove the battery pack out of the power tool, if it is removable. These preventative safety measures limit the danger of accidentally starting the power tool.
   • d) When not used, the power tool must be stored out of children‘s reach, and persons not acquainted with the power tool or these instructions must not be permitted to use the power tool. A power tool in the hands of inexperienced users is dangerous.
   • e) Power tools and accessories need to be maintained. It is necessary to check the adjustment of moving parts and their movement; focus on cracks, broken parts or any other circumstances that may threaten the proper operation of the power tool. If the power tool is damaged, it is necessary to have it repaired before using it again. Many accidents are caused by insufficiently maintained power tools.
   • f) It is necessary to keep cutting power tools clean and sharp. Correctly maintained and sharpened cutting power tools are less likely to get stuck on material or to jam and they are also easier to control.
   • g) It is necessary to use power tools, accessories, working tools, etc. in accordance with these instructions and in such a manner as prescribed for the specific power tool with respect to the given work conditions and the type of work being performed. Using power tools for tasks other than for which they are designed may lead to dangerous situations.
   • h) Handles and grip surfaces must be kept dry, clean and free of grease. Slippery handles and grip surfaces do not ensure a safe grip and control over the power tool in unexpected situations.
5. OPERATING AND MAINTAINING CORDLESS POWER TOOLS
   • a) The power tool charge only using the charger specified by the manufacturer. A charger that may be suitable for one type of battery pack, may lead to a fire hazard if used with a different battery pack.
   • b) Only use the tool with a battery pack that is explicitly determined for the given tool. Using any other battery pack may create a accident or fire hazard.
   • c) When the battery pack is not being used, protect it against contact with other metal items such as paper clips, coins, keys, nails, screws or other small metal items that could make a connection between both battery contacts. Short circuiting the battery contacts may cause burns or a fire.
   • d) Incorrect use may cause liquids to leak out of the battery; avoid coming into contact with them. In the event of accidental contact with these liquids, rinse the affected area with water. In the event that the liquid enters the eye, seek medical help. Liquids leaking from the battery may cause inflammations or burns.
   • e) A battery pack or power tool that is damaged or modified, must not be used. Damaged or modified batteries may behave erratically, which may result in a fire, an explosion or an injury hazard.
   • f) Battery packs or power tools must not be exposed to a fire or excessive heat. Exposure to fire or a temperature exceeding 130°C may result in an explosion.
   • g) It is necessary to adhere to all battery charging instructions and not to charge the battery pack or power tool outside the temperature range specified in this user‘s manual. Incorrect charging, or charging at temperatures outside the specified range may damage the battery and increase the risk of fire.
6. SERVICE
