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

2. Electrical Safety

3. Personal Safety

4. Tool Use and Care

control.

(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.

(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 with 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.

(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.

English

(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

5. Service

be suitable for one tool, may become hazardous when used on another tool.

(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.

SPECIFIC SAFETY RULES

Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

2. Never touch moving parts.

Never place your hands, fingers or other body parts near the tool’s moving parts.

3. Never operate without all guards in place.

Never operate this tool without all guards or safety features in place and in proper working order. If maintenance or servicing requires the removal of a guard or safety feature, be sure to replace the guard or safety feature before resuming operation of the tool.

4. Use right tool.

Don’t force small tool or attachment to do the job of a heavy-duty tool. Don’t use tool for purpose not intended —for example— don’t use circular saw for cutting tree limbs or logs.

5. Never use a power tool for applications other than those specified.

Never use a power tool for applications other than those specified in the Instruction Manual.

6. Handle tool correctly.

Operate the tool according to the instructions provided herein. Do not drop or throw the tool. Never allow the tool to be operated by children, individuals unfamiliar with its operation or unauthorized personnel.

7. Definitions for symbols

V ................. volts no.................... no load speed

2. Installing the bit (Impact driver)

Always follow the following procedure to install driver bit. (Fig. 10) (1) Pull the guide sleeve back. (2) Insert the bit into the hexagonal hole in the anvil. (3) Release the guide sleeve and it returns to its original position.

CAUTION:

If the guide sleeve does not return to its original position, then the bit

●

is not installed properly.

3. Removing the bit (Impact driver)

Please do the opposite point on the method of installing bit.

4. Selecting the socket matched to the bolt (Impact wrench)

Be sure to use a socket which is matched to the bolt to be tightened. Using an improper socket will not only

result in insufficient tightening but also in damage to the socket or nut.

A worn or deformed hex. or square-holed socket will not give an adequate tightness for fitting to the nut or

anvil, consequently resulting in loss of tightening torque.

Pay attention to wear of socket hole, and replace before further wear

has developed.

5. Installing a socket (Impact wrench)

Align the plunger located in the square part of the anvil with the hole in

the hex. socket. Then push the plunger, and mount the hex. socket on

the anvil. Check that the plunger is fully engaged in the hole. When

removing the socket, reverse the sequence. (Fig. 11)

6. Retaining ring type (Impact wrench)

(1) Align the square portions of the socket and the anvil with each other. (2) Make sure to firmly install the socket by pushing it all the way into the

anvil. (3) When removing the socket, pull it out of the anvil.

Accidents or injuries could result from not doing so.

●

Make sure to firmly install the socket in the anvil. If the socket is not firmly installed it might come out and cause injuries.

7. Confirm that the battery is mounted correctly

8. Check the rotational direction

The bit rotates clockwise (viewed from the rear side) by pushing the Rside of the push button. The L-side of the push button is pushed to turn the bit counterclockwise. (See Fig. 12)

CAUTION: The push button can not be switched while the impact driver is turning.

●

To switch the push button, stop the impact driver, then set the push button.

9. Switch operation

䡬

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

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work

2. Cautions on use of the speed control switch

A buzzing noise is produced when the motor is about to rotate; this is only a noise, not a machine failure.

As shown in Fig.13, when the rotation switch-over lever is slid to the lower side, the power mode (P) is set. And when slid to upper side, the save mode (S) is set. Please use the save mode (S) when you want to lower Maximum tightening torque.

CAUTION: In the work of the save mode (S), avoid the continuous screw-tightening as temperature of electronic components of the converter switch increases.

Install the bit that matches the screw, line up the bit in the grooves of the head of the screw, then tighten it. Push the impact driver just enough to keep the bit fitting the head of the screw.

CAUTION: Applying the impact driver for too long tightens the screw too much and can break it. Tightening a screw with the impact driver at an angle to that screw can damage the head of the screw and the proper force will not be transmitted to the screw. Tighten with this impact driver lined up straight with the screw.

A hex. socket matching the bolt or nut must first be selected. Then mount the socket on the anvil, and grip the nut to be tightened with the hex. socket. Holding the wrench in line with the bolt, press the power switch to impact the nut for several seconds. If the nut is only loosely fitted to the bolt, the bolt may turn with the nut, therefore mistaking proper tightening. In this case, stop impact on the nut and hold the bolt head with a wrench before restarting impact, or manually tighten the bolt and nut to prevent them slipping.

After use for continuous bolt-tightening work, 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.

CAUTION: Do not touch the protector, as it gets very hot during continuous work.

This switch has a built-in, electronic circuit which steplessly varies the rotation speed. Consequently, when the switch trigger is pulled only slightly (low speed rotation) and the motor is stopped while continuously driving in screws, the components of the electronic circuit parts may overheat and be damaged.

3. Use a tightening time suitable for the screw

The appropriate torque for a screw differs according to the material and size of the screw, and the material

being screwed etc., so please use a tightening time suitable for the screw. In particular, if a long tightening

time is used in the case of screws smaller than 5/16” (8 mm), there is a danger of the screw breaking, so

please confirm the tightening time and the tightening torque beforehand.

4. Work at a tightening torque suitable for the bolt under impact

The optimum tightening torque for nuts or bolts differs with material and size of the nuts or bolts. An

excessively large tightening torque for a small bolt may stretch or break the bolt. The tightening torque

increases in proportionate to the operation time. Use the correct operating time for the bolt.

5. Holding the tool

Hold the impact wrench firmly with both hands. In this case hold the wrench in line with the bolt.

It is not necessary to push the wrench very hard. Hold the wrench with a force just sufficient to counteract the impact force.

6. Confirm the tightening torque

The following factors contribute to a reduction of the tightening torque. So confirm the actual tightening torque needed by

screwing up some bolts before the job with a hand torque wrench. Factors affecting the tightening torque are as follows. (1) Voltage

When the discharge margin is reached, voltage decreases and tightening torque is lowered. (2) Operating time

The tightening torque increases when the operating time increases. But the tightening torque does not increase

above a certain value even if the tool is driven for a long time. (3) Diameter of bolt

The tightening torque differs with the diameter of the bolt. Generally a larger diameter bolt requires larger

tightening torque. (4) Tightening conditions

The tightening torque differs according to the torque ratio, class, and length of bolts even when bolts with the

same size threads are used. The tightening torque also differs according to the condition of the surface of workpiece

through which the bolts are to be tightened. When the bolt and nut turn together, torque is greatly reduced. (5) Using optional parts (Impact wrench)

The tightening torque is reduced a little when an extension bar, universal joint or a long socket is used. (6) Clearance of the socket (Impact wrench)

A worn or deformed hex. or a square-holed socket will not give an adequate tightness to the fitting between

the nut or anvil, consequently resulting in loss of tightening torque.

Using an improper socket which does not match to the bolt will result in an insufficient tightening torque.

MAINTENANCE AND INSPECTION

CAUTION:

Pull out battery before doing any inspection or maintenance.

1. Checking the condition of the bit (Impact driver)

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. Checking the condition of the socket (Impact wrench)

A worn or deformed hex. or a square-holed socket will not give an adequate tightness to the fitting between

the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of a socket holes

periodically, and replace with a new one if needed.

3. 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.

4. 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.

English

5. Inspecting the carbon brushes (Fig. 14)

Wear limit 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.

6. 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,

Nail of carbon brush

etc., as shown in Fig. 16. 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
