GENERAL POWER TOOL SAFETY WARNINGS

WARNING
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed 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 battery-operated (cordless) power tool.

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

2.  Electrical safety
   a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
   b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
   c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   d) Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
   e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
   f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. The use of an RCD reduces the risk of electric shock.

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 while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
   b) Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
   c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
   d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
   g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.
   h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

4. Power tool use and care
   a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate at which it was designed. b) Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   c) Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   d) Store idle 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) Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
   f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   g) Use the power tool, accessories and tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
   h) Keep handles and grasping surfaces dry, clean, and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5. Battery tool use and care
   a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
   b) Use power tools only with specifically designated battery packs. The use of any other battery packs may create a risk of injury and fire.
   c) When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
   d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
   e) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion, or risk of injury.
   f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C may cause an explosion.
   g) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may 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 will ensure that the safety of the power tool is maintained.
   b) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

CAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of children and infirm persons.

CORDLESS SCREWDRIVER SAFETY WARNINGS

1. Hold the power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring.
   Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

ADDITIONAL SAFETY WARNINGS

1. This is a portable tool for tightening and loosening screws. Use it only for this operation.

2. During operation, make sure to firmly hold the tool’s handle. Failure to do so may result in injury. (Fig. 1)

3. Ensure that the spot where you wish to work is free of power cables, gas lines or water pipes (e.g. using a metal detector).

4. Smaller workpieces must be secured in such a way that they are not carried along with the bit (e.g. by clamping in a vice or on a workbench with screw Fig. 1 clamps).

5. Do not keep the ventilation slots closed.

6. Never touch the moving parts. Never place your hands, fingers, or other body parts near the tool’s moving parts.

7.  Make sure that the battery is installed firmly. If it is at all lost it could come off and cause an accident.

8. After installing the driver bit, pull lightly out the bit to make sure that it does not come loose. If the bit is not installed properly, it can come loose during use, which can be dangerous.

9. Screw-in screws with the main unit held straight. If the driver is slanted relative to the screw, the screw head can be damaged and a bit worn. Moreover, the prescribed torque is not transmitted to the screw, resulting in screws left sticking out. Place the drive straight against the screw and screw in.

10. Use the prescribed screws. Do not use any other screws. They can cause abnormal work (screws falling over or sticking out) and breakdowns (screw jamming and bit wear).

11. Watch out for wires and pipes in walls and ceilings. When working on floors, walls, or ceilings, check for wires and pipes ahead of time. Work carefully to avoid shocks and explosions.

12. Protect your eyes with protective glasses. Always wear protective glasses while working. Drilling scatters plaster powder and tape dust, which are dangerous if they get into your eyes

13. Use the earplugs if used for a long time.

14. The motor may stop in the event the tool is overloaded. If this should occur,
    release the tool’s switch and eliminate the cause of the overload.

15. Do not touch the metal parts, as it gets very hot during continuous work.

16. The use of the battery in a cold condition (below 0 degrees Centigrade) can sometimes result in weakened tightening torque and a reduced amount of work. This, however, is a temporary phenomenon and returns to normal when the battery warms up.

17. Always use the tool and battery at temperatures between -5°C and 40°C.

18. Always charge the battery at a temperature of 0­40°C. A temperature of less than 0°C will result in overcharging which is dangerous. The battery cannot be charged at a temperature greater than 40°C. The most suitable temperature for charging is that of 20­25°C.

19. Do not use the charger continuously. When one charging is completed, leave the charger for about 15 minutes before the next charging of the battery.

20. Do not allow foreign matter to enter the hole for connecting the battery.

21. Never disassemble the battery and charger.

22. Never short-circuit the battery. Short-circuiting the battery will cause a great electric current and overheating. It results in burn or damage to the battery.

23. Do not dispose of the battery in fire. If the battery burns, it may explode.

24. Do not insert objects into the air ventilation slots of the charger. Inserting metal objects or inflammable into the charger air ventilation slots will result in electrical shock hazards or damaged chargers.

25. Bring the battery to the shop from which it was purchased as soon as the post-charging battery life becomes too short for practical use. Do not dispose of the exhausted battery.

26. Do not use the product if the tool or the battery terminals (battery mount) are deformed. Installing the battery could cause a short circuit that could result in smoke emission or ignition.

27. Keep the tool’s terminals (battery mount) free of swarf and dust.
    Prior to use, make sure that swarf and dust have not collected in the area of the
    terminals.
    During use, try to avoid swarf or dust on the tool from falling on the battery. When suspending operation or after use, do not leave the tool in an area where it
    may be exposed to falling swarf or dust.
    Doing so could cause a short circuit that could result in smoke emission or ignition.

CHARGING

Before using the power tool, charge the battery as follows.

1. Connect the charger’s power cord to the receptacle.
   When connecting the plug of the charger to a receptacle, the pilot lamp will blink in red (At 1-second intervals).

2. Insert the battery into the charger. Firmly insert the battery into the charger as shown in Fig. 8.

3. Charging. When inserting a battery in the charger, charging will commence and the pilot lamp will light continuously in red.
   When the battery becomes fully recharged, the pilot lamp will blink in red. (At 1-second intervals) (See Table 2 on page 32) • Pilot lamp indication
   The indications of the pilot lamp will be as shown in Table 2, according to the condition of the charger or the battery. • Regarding the temperatures and charging time of the battery.
   The temperatures and charging time will become as shown in Table 3. Table 3 NOTE
   The recharging time may vary according to temperature and power source voltage.
   CAUTION
   When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging.

4. Disconnect the charger’s power cord from the receptacle

5. Hold the charger firmly and pull out the battery

NOTE
Be sure to pull out the battery from the charger after use, and then keep it.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and the normal time required for recharging will be restored by recharging the batteries 2­3 times.

How to make the batteries perform longer.

1. Recharge the batteries before they become completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
2. Avoid recharging at high temperatures. A battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

CAUTION

• If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, but does not light for 0.5 seconds (off for 0.5 seconds). In such a case, first, let the battery cool, then start charging.
• When the pilot lamp flickers (at 0.2-second intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.
• If the pilot lamp does not blink in red (every second) even though the charger cord is connected to the power, it indicates that the protection circuit of the charger may be activated. Remove the cord or plug from the power and then connect it again after 5 minutes or so. If this does not cause the pilot lamp to blink in red (every second), please take the charger to the HiKOKI Authorized Service Center.

PRIOR TO OPERATION
Check the work area to make sure that it is clear of debris and clutter. Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

OPERATIONAL CAUTIONS

Resting the unit after continuous work After use for continuous bolt- tightening work, rest the unit for 15 minutes or so when replacing the battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout.

MAINTENANCE AND INSPECTION

WARNING
To avoid serious accidents, ensure the switch is in the OFF position, and pull out the battery.

1. Inspecting the bit Using a broken bit or one with a worn-out tip is dangerous because the bit can slip. Replace it.

2. Clean stiff stopper If the depth setting is stiff, the stopper can be dismantled without using tools. To do this, turn the setting sleeve clockwise until it becomes loose from the union sleeve. Twist out the stop sleeve and clean the thread.
   NOTE
   Only clean or vacuum mechanically. Do not use oils or greases. Regularly remove and clean the stopper

3. Inspecting the mounting screws Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so may result in serious hazards.

4. Maintenance of the motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

5. Inspection of terminals (tool and battery) Check to make sure that swarf and dust have not been collected on the terminals. On occasion check prior, during, and after the operation.
   CAUTION
   Remove any swarf or dust which may have collected on the terminals. Failure to do so may result in malfunction.

6. Cleaning of the outside When the power tool is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline, or paint thinner, as they melt plastics. Particles may become deposited inside the power tool during operation. This impairs the cooling of the power tool. The power tool should be cleaned regularly, often and thoroughly through all front and rear air vents using a vacuum cleaner. Prior to this operation, separate the power tool from the power source and wear protective goggles and a dust mask.

7. Environmental protection Observe national regulations on environmentally compatible disposal and on the recycling of disused machines, packaging, and accessories.

8. Storage
   Store the impact driver in a place in which the temperature is less than 40°C, and out of reach of children.
   NOTE
   Storing Lithium-ion Batteries
   Make sure the batteries have been fully charged before storing them. Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, significantly reducing battery usage time or rendering the batteries incapable of holding a charge.
   However, significantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to five times.
   If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.

CAUTION
In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.
Important notice on the batteries for the HiKOKI cordless power tools
Please always use one of our designated genuine batteries. We cannot guarantee the safety and performance of our cordless power tool when used with batteries other than those designated by us, or when the battery is disassembled and modified (such as disassembly and replacement of cells or other internal parts).
