SAFETY

GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS

WARNING: Read and understand all instructions.

Failure to follow all instructions listed below, may result in electric 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.

A charger that may be suitable for one type of battery may create a risk of fire 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. 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 in the locked or off position before

inserting battery pack. 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. Proper footing 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.

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. A tool that cannot be controlled

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) Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

(6) 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.

(7) 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.

(8) Check for misalignment or binding of moving parts, breakage of parts, and any

other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

(9) Use only accessories that are recommended by the manufacturer for your model.

Accessories that may be suitable for one tool may create a risk of injury 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 shock or injury.

English

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause 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.

2. Confirm that the battery is mounted correctly.

CAUTION: Install the battery properly.

If not installed properly, it may fall out of the power tool and cause danger.

3. Check the rotational direction

The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the selector button. The L-side of the selector button is pushed to turn the bit counterclockwise. (See Fig. 7). (The

andRmarks are provided on the body.)

4. Switch operation

䡬 When the switch trigger is depressed, the tool rotates. When the trigger is released,

the tool stops.

䡬 The rotational speed can be controlled by varying the amount that the switch trigger

is pulled. Speed is low when the switch trigger is pulled slightly and increases as the switch trigger is pulled more.

English

NOTE: A buzzing noise is produced when the motor is about to rotate; this is only a noise,

not a machine failure.

5. To use for drilling metal

䡬 In case you drill metal with an iron-working drill bit, apply in advance a center punch

in the drilling position. You can drill metal stably since the point of the drill bit does not slip.

䡬 If you apply sewing machine oil or soapy water to the drill bit with a brush or an old

tooth brush, the drill bit will last long.

䡬 When drilling a hole, it cannot be drilled more rapidly by applying more than the

required force. On the contrary, the edge of the drill bit will be damaged. This will decrease operational efficiency and shorten the life of this POWER TOOL.

CAUTION:

䢇 The motor rotation may be locked to cease while the Cordless angle drill is used as a

drill. The motor must be burnt or the battery life must remarkably be reduced when the locked condition is continued for several seconds.

䢇 Drilling a hole in the metal exerts considerable force on the edge of the hole so that the

drill bit may slip from the keyless chuck. If this happens, decrease the pushing pressure on the Cordless angle drill so that the drill bit does not slip.

䢇 While operating the Cordless angle drill, take care not to lock the motor. If the motor

is locked, immediately turn the power off.

䢇 Do tighten too strongly as the screw heads will be damaged. 䢇 When pressing the tool against the object to be drilled, take care not to touch the

keyless chuck with your hands.

MAINTENANCE AND INSPECTION

CAUTION: Pull out battery before doing any inspection or maintenance.

1. Checking the condition of the bit.

The bits should be checked regularly. If worn or broken bits can slip or decrease the efficiency of the motor and burn it out. Replace worn bits with new ones.

CAUTION: If you use a driver bit of which point is worn or broken, it will be dangerous

since it slips. So replace it with a new one.

2. Check the Screws

Loose screws are dangerous. Regularly inspect them and make sure they are tight.

CAUTION: Using this power tool with loosened screws is extremely dangerous.

3. Check for Dust

Dust may be removed with a soft cloth or a cloth dampened with soapy water. Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics.
