GENERAL POWER TOOL SAFETY WARNINGS

WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, ﬁ re, 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.

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.
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. Unmodiﬁ ed 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. 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. Use of an RCD reduces the risk of electric shock.
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 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 the switch is in the oﬀ position before connecting to 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 jewellery. Keep your hair, clothing, and gloves away from moving parts.
Loose clothes, jewellery, 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. Use of dust collection can reduce dust-related hazards.
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 it 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 the battery pack 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. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may aﬀ ect the power toolʼs 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. in accordance with these instructions, taking into account the working conditions and the work to be performed.
Use of the power tool for operations diﬀ erent from those intended could result in a hazardous situation.

Battery tool use and care
a) Recharge only with the charger speciﬁ ed by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of ﬁ re when used with another
battery pack.
b) Use power tools only with speciﬁ cally designated battery packs. Use of any other battery packs may create a risk of injury and ﬁ re.
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 ﬁ re.
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.

Service
a) Have your power tool serviced by a quality ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

PRECAUTION
Keep children and inﬁ rm persons away.
When not in use, tools should be stored out of reach of children and inﬁ rm persons.

CORDLESS IMPACT WRENCH
SAFETY WARNINGS
Hold 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

This is a portable tool for tightening and loosening bolts and nuts. Use it only for this operation.
Make sure to securely hold the tool during operation. Failure to do so can result in accidents or injuries.
Make sure that the battery is installed ﬁ rmly. If it is as all loose it could come oﬀ and cause an accident.
Preparing and checking the work environment. Make sure that the work site meets all the conditions laid forth in the precautions.
Do not allow foreign matter to enter the hole for connecting the rechargeable battery.
Never disassemble the rechargeable battery and charger.
Never short-circuit the rechargeable battery. Shortcircuiting the battery will cause a great electric current and overheat. It results in burn or damage to the battery.
Do not dispose of the battery in ﬁ re. If the battery is burnt, it may explode.
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.
Do not insert object into the air ventilation slots of the charger. Inserting metal objects or inﬂ flammables into the charger air ventilation slots will result in electrical shock
hazard or damaged charger.
Check the actual tightening torque with a toruqe wrench.
Stop the tool before switching the direction of rotation. Always release the switch and wait for the tool to stop before switching the direction of rotation.
Never touch the turning part. Do not allow the turning part section to get near your hands or any other part of your body. You could be cut or caught in the turning part.
Also, be careful not to touch the turning part after using continuously it for a long time. It gets quite hot and could burn you.
Please use the designated attachments which are listed in the operations manual and HiKOKI’s catalog. Accidents or injuries could result from not doing so.
Make sure to ﬁrmly install the attachments in the anvil. If the attachment is not ﬁrmly installed it might come out and cause injuries.
Tightening mode selector function Select tightening mode while the trigger switch is released. Failure to do so could result in malfunction. The appropriate mode diﬀ ers depending on the bolts and the material being screwed. Tighten in a few test bolts and adjust the mode setting accordingly. The tightening mode selector switch can only be set after the battery has been installed in the tool and the trigger switch has been pulled once.
The power tool is equipped with a temperature protection circuit to protect the motor. Continuous work may cause the temperature of the unit to rise, activating the temperature protection circuit and automatically stopping operation. If this happens, allow the power tool to cool before resuming use.
The motor may stop in the event the tool is overloaded. In this should occur, release the tool’s switch and eliminate the cause of the overload. Avoid touching the front case which can heat up during continuous operation.
The use of the battery in a cold condition (below 0 degree 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.
The push-button can not be switched while the power tool is turning. To switch the push button, stop the power tool, then set the push button.
Install securely the hook. Unless the hook is securely installed, it may cause an injury while using. When electing to carry the tool hooked to your hip belt, make sure to detach the tool socket. Failure to do so may result in unexpected injury.
Do not give a strong shock to the switch panel or break it. It may lead to trouble.
Do not look directly into the light. Such actions could result in eye injury. Wipe oﬀ any dirt or grime attached to the lens of the LED light with a soft cloth, being careful not to scratch the lens. Scratches on the lens of the LED light can result in decreased brightness.
To prevent the battery power consumption caused by forgetting to turn oﬀ the LED light, the light goes oﬀ automatically in about 2 minutes.
Resting the unit after continuous work.
Do not touch the hammer case, as it gets very hot during continuous work.
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.
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.
