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 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. 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

English

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. Any 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 tools 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 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 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.

Make sure to grasp the plug when removing from receptacle to avoid damaging cord.

5.Remove the battery from the battery charger.

Supporting the battery charger with hand, pull out the battery from the battery charger.

CAUTION:

●When the battery charger has been continuosly 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.

●If the battery is rechraged when it is warm due to battery use or exposure to sunlight, the pilot lamp may light in green.

The battery will not be recharged. In such a case, let the battery cool before charging.

●When the pilot lamp flickers in red (at 0.2–second intervals), check for and take out any foreign objects in the charger’s battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

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

(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 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.

4. Disconnect battery charger from the receptacle.

CAUTION:

Do not pull the plug out of the receptacle by pulling on the cord.

Make sure to grasp the plug when removing from receptacle to avoid damaging cord.

5.Remove the battery from the battery charger.

Supporting the battery charger with hand, pull out the battery from the battery charger.

CAUTION:

●Repair is required if the receptacle is not secured properly or the power cord does not stay in the receptacle. Consult your electrician. Using the charger in this condition may lead to fire.

●If the charge status lamp is blinking orange rapidly (in 0.2 second intervals) and the buzzer sounds intermittently for 5 seconds, check that the hole for connecting the battery is not obstructed. Remove any obstructions. If no obstructions are found, the battery or charger may be malfunctioned. Return both to your place of purchase.

●If the charge time lamp does not light when the power cord is connected to the receptacle, disconnect the power cord, and check that the battery is attached correctly.

●The battery retains heat when used or left for prolonged periods in direct sunlight. In this state, the charge time lamp flashes red, and the battery cannot be charged immediately. Leave the battery inserted in the charger, and charging will commence when the battery cools down.

18

English

●If the lamp goes out while charging, disconnect the power cord, and leave for 3 to 5 minutes before reconnecting. If the problem persists, call for repairs.

●Leave 5 minutes between charging batteries as the charger may overheat leading to malfunction.

●The battery life is finished if it can only be used for short periods even when fully

charged. Purchase a new battery. Continuing to use a depleted battery may cause the charger to malfunction.

NOTE:

Charging times may be longer depending on the surrounding temperature and battery conditions.

Charge time lamp indications are only a guide, and may vary depending on the surrounding temperature and battery conditions.

Remove the battery from the charger when not in use.

Revitalizing the battery (trickle recharge)

A new battery or a battery that has not been used for extensive periods may not charge completely due to internal chemicals being inert.

Leave the battery inserted in the charger for 8 to 12 hours after charging is complete. The charger automatically “revitalizes” the battery by trickle recharging.

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 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.

BEFORE USE

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.

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.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.

4.Inspecting the carbon brushes (Fig. 24)

The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

NOTE:

When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 999054.

5.Replacing carbon brushes

Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a flat head screw driver, etc., as shown in Fig. 26.

When installing the carbon brush, choose the direction so that the nail of the carbon brush agrees with the contact portion outside the brush tube. Then push it in with a finger as illustrated in Fig. 27. Lastly, install the brush cap.
