SAFETY
GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS
WARNING: Read and understand all instructions.
Failuretofollowallinstructions listed below, may result inelectric shock,
fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
1. Work Area
(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
(2) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks which may ignite the
dust of fumes.
(3) Keep bystanders, children and visitors away while operating a power tool.
Distractions can cause you to lose control.
2. Electrical Safety
(1) A battery operated tool with integral batteries or a separate battery pack must be
recharged only with the specified charger for the battery.
Acharger thatmaybe suitableforone typeofbattery may createa risk offire when
used with another battery.
(2) Use battery operated tool only with specifically designed battery pack.
Use of any other batteries may create a risk of fire.
(3) Do not abuse the cord. Never use the cord to carry the tools or pull the plug from
an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock.
3. Personal Safety
(1) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use tool while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power tools may result in
serious personal injury.
(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or
long hair can be caught in moving parts.
(3) Avoid accidental starting. Be sure switch is off position before inserting battery.
Carrying tools with your finger on the switch or inserting the battery pack into a
tool that have the switch on invites accidents.
(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key
that is left attached to a rotating part of the tool may result in personal injury.
(5) Do not overreach. Keep proper footing and balance at all times. Properfooting and
balance enable better control of the tool in unexpected situations.
(6) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.

English
5
4. Tool Use and Care
(1) Use clamps or other practical way to secure and support the workpiece to a stable
platform. Holding the work by hand or against your body is unstable and may lead
to loss of control.
(2) Do not force tool. Use the correct tool for your application. The correct tool will do
the job better and safer at the rate for which it is designed.
(3) Do not use tool if switch does not turn it on or off. Anytoolthatcannotbecontrolled
with the switch is dangerous and must be repaired.
(4) Disconnect battery pack from tool or place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tools. Such
preventive safety measures reduce the risk of starting the tool accidentally.
(5) Disconnect the battery or cord form the tool before making any adjustments,
changing accessories, or storing the tool. Such preventive safety measures reduce
the risk of starting the tool accidentally (when used with power supply).
(6) Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
(7) 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 sparks, burns, or a fire.
(8) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained
tools, with sharp cutting edges are less likely to bind and are easier to control.
(9) Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tools operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
(10)Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool, may become hazardous when used
on another tool.
5. Service
(1) Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
(2) When servicing a tool, use only identical replacement parts. Follow instructions in
the Maintenance section of this manual. Use of unauthorized parts or failure to
follow Maintenance Instruction may create a risk of electric shock or injury.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction
activitiescontainschemicalsknowntothe State of California tocause cancer, birth defects
or other reproductive harm. Some examples of these chemicals are:
●Lead from lead-based paints,
●Crystalline silica from bricks and cement and other masonry products, and
●Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.

Make sure to grasp the plug when removing from receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supportingthe battery chargerwithhand, pull outthebattery from thebatterycharger.
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 normal
time required for recharging will be restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer.
䡬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.
䡬Avoid recharging at high temperatures.
A rechargeable 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:
䢇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.
䢇If the battery is recharged when it is warm due to battery use or exposure to sunlight,
the pilot lamp may not light.
The battery will not be recharged. In such a case, let the battery cool before charging.
䢇Ifthebatterychargerdoesnotworkwhilethe battery is mounted correctly, it is probable
that the battery or charger is malfunctioning. Take it to your authorized Service Center.
