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
- Keep work area clean and well lit.
  Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of ﬂ ammable liquids, gases or dust.
  Power tools create sparks which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool.
  Distractions can cause you to lose control.
Electrical safety
- 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 risk of electric shock.
- 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.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- 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.
- 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.
- 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.
Personal safety
- 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 inﬂ uence of drugs, alcohol or medication.
  A moment of inattention while operating power tools may result in serious personal injury.
- 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.
- Prevent unintentional starting. Ensure 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 ﬁ nger on the switch or energising power tools that have the switch on invites accidents.
- 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.
- Do not overreach. Keep proper footing and balance at all times.
  This enables better control of the power tool in unexpected situations.
- 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.
- 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.
Power tool use and care
- 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 for which it was designed.
- 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.
- 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.
- 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.
- 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.
- Keep cutting tools sharp and clean.
  Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
- 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 diﬀ erent from those intended could result in a hazardous situation.
Battery tool use and care
- 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.
- Use power tools only with speciﬁ cally designated battery packs.
  Use of any other battery packs may create a risk of injury and ﬁre.
- When 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.
- Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, ﬂ ush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
Service
- Have your power tool serviced by a qualiﬁ 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 MULTI TOOL SAFETY WARNINGS

Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring.
Cutting accessory 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

Always hold the tool ﬁ rmly with one hand on housing ( Fig. 10 ). Do not touch the metal part.
Make sure that the area to be cut is absolutely free of any hidden obstructions including electrical wiring, water, or gas pipes. Cutting into the aforementioned may result in electric shock or short circuit, gas leak or other hazards that can cause serious accidents or injuries.
Make sure to securely hold the tool during operation. Failure to do so can result in accidents or injuries.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Setting up and checking the work environment. Check if the work environment is suitable by following the precaution.
Dust particles such as silica or asbestos are hazardous to your health. When working with materials containing these components, take appropriate dust-prooﬁ ng measures.
Working with metal can cause sparks. Make sure there are no ﬂ ammable and combustible materials in the vicinity and that they are stored in a safe location.
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 objects into the air ventilation slots of the charger. Inserting metal objects or inﬂ ammables into the charger air ventilation slots will result in electrical shock hazard or a damaged charger.
After use for continuous cutting or grinding works, 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.
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.
The use of the battery in a cold condition (below 0 degrees Centigrade) can sometimes result in a weakened tightening torque and reduced amount of work. This, however, is a temporary phenomenon and returns to normal when the battery warms up.
Do not look directly into the light. Such actions could result in eye injury.
Do not touch the application tool, its attachment area or other metal surfaces immediately after use as they will be hot. Doing so may result in burns or injury.
The metal is hot and can easily burn your skin.
Make sure that there is no one below when operating the tool in high locations. Dropping the tool or materials may result in an accident or injury.
Never apply any unreasonable force to the application tool when working. Doing so may break the application tool or damage the motor.
Do not leave the tool running unattended on the ﬂoor, table or other locations. Doing so may result in injury.
When attaching application tools, be careful not to get your ﬁngers or other extremities caught in the lever.
If the application tool seems to be loose or uneven after attaching it to the unit, follow the instructions in Fig. 5 and re-attach the tool. Operating the unit with a loose or uneven application tool may result in injury.
When switching on the tool, make sure the application tool is not in contact with any processing materials. Failure to do so may result in injury.
For cutting e ﬃciency, switch the mode of the application tool according to task conditions and materials to be cut.
After use, be sure not to place the tool near chips or sawdust before it comes to a full stop as the tool may suck in those particles.
Do not polish wood with sanding paper used for metal polishing.
Do not use worn or clogged sanding paper.

CAUTION ON LITHIUM-ION BATTERY

To extend its lifetime, the lithium-ion battery equips with a protection function to stop the output.
In the cases 1 to 3 described below, when using this product, even if you are pulling the switch, the motor may stop. This is not the trouble but the result of the protection function.

When the battery power remaining runs out, the motor stops.
In such a case, charge it up immediately.
If the tool is overloaded, the motor may stop. In this case, release the switch of tool and eliminate causes of overloading. After that, you can use it again.
If the battery is overheated under overload work, the battery power may stop.
In this case, stop using the battery and let the battery cool. After that, you can use it again.

Pilot lamp indication
The indications of the pilot lamp will be as shown in Table 1, according to the condition of the charger or the rechargeable battery.

Regarding the temperatures and charging time of the battery.
The temperatures and charging time will become as shown in Table 2.

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.

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

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, 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 ﬂ ickers (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.
Since the built-in microcomputer takes about 3 seconds to conﬁ rm that the battery being charged with the charger is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.
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 30 seconds 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.

MAINTENANCE AND INSPECTION

Inspecting the application tool
Continued use of a dull or damaged application tool will result in reduced cutting eﬃciency and may cause overloading of the motor. Replace the application tool with a new one as soon as excessive abrasion is noted.
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 could result in serious hazards.
Maintenance of the motor
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.
Cleaning on 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, for they melt plastics.
Storage
Store the power tool in a place in which the temperature is less than 40°C and out of reach of children.
NOTE
Make sure that the battery is fully charged when stored for a long period (3 months or more). The battery with a smaller capacity may not be able to be charged when used, if stored for a long period.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully charged before storing them.
Prolonged storage 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 ﬁ ve times.
If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.
