SAFETY

GENERAL SAFETY RULES

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) Double Insulated tools are equipped with a polarized plug (one blade is

wider than the other.) This plug will fit in a polarized outlet only one

way. If the plug does not fit fully in the outlet, reverse the plug. If it still

does not fit, contact a qualified electrician to install a polarized outlet.

Do not change the plug in any way. Double Insulation

eliminates the

need for the three wire grounded power cord and grounded power supply

system.

(2) Avoid body contact with grounded surfaces such as pipes, radiators,

ranges and refrigerators. There is an increased risk of electric shock if your

body is grounded.

(3) Do not expose power tools to rain or wet conditions. Water entering a

power tool will increase the risk of electric shock.

(4) Do not abuse the cord. Never use the cord to carry the tools or pull the

plug from a receptacle. Keep cord away from heat, oil, sharp edges or

moving parts. Replace damaged cords immediately. Damaged cords

increase the risk of electric shock.

(5) When operating a power tool outside, use an outdoor extension cord

marked “W-A” or “W”. These cords are rated for outdoor use and reduce

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.

01Eng_WR22SA_US 10/26/07, 18:234

English

(3) Avoid accidental starting. Be sure switch is off before plugging in. Carrying

tools with your finger on the switch or plugging in tools 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 enables 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. Any tool that cannot be

controlled with the switch is dangerous and must be repaired.

(4) Disconnect the plug from the power source before making any adjustments,

changing accessories, or storing the tool. 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) 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.

(7) 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.

(8) 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 with 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.

DOUBLE INSULATION FOR SAFER OPERATION

To ensure safer operation of this power tool, HITACHI has adopted a double insulation

design. “Double insulation” means that two physically separated insulation systems

have been used to insulate the electrically conductive materials connected to the

power supply from the outer frame handled by the operator. Therefore, either the

symbol “

” or the words “Double insulation” appear on the power tool or on the

nameplate.

Although this system has no external grounding, you must still follow the normal

electrical safety precautions given in this Instruction Manual, including not using

the power tool in wet environments.

To keep the double insulation system effective, follow these precautions:

䡬 Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble

this power tool, and only genuine HITACHI replacement parts should be installed.

䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy

water, and dry thoroughly.

Never use solvents, gasoline or thinners on plastic components; otherwise the

plastic may dissolve.

ASSEMBLY AND OPERATION

APPLICATIONS

䡬 Tightening and loosening various kinds of bolts and nuts.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power source

requirements specified on the product nameplate.

2. Power switch

Ensure that the switch is in the OFF position. If the plug is connected to a

receptacle while the switch is in the ON position, the power tool will start operating

immediately and can cause serious injury.

3. Extension cord

When the work area is far away from the power source, use an extension cord of

sufficient thickness and rated capacity. The extension cord should be kept as

short as practicable.

WARNING:

Damaged cord must be replaced or repaired.

4. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired.

Contact a licensed electrician to make appropriate repairs.

If such a faulty receptacle is used, it may cause overheating, resulting in a serious

hazard.

5. Confirming condition of the environment

Confirm that the work site is placed under appropriate conditions conforming to

prescribed precautions.

6. Attacking the side handle

The position of the side handle attached to the hammer case can be changed by

unscrewing the handle. (Right hand screw) Turn the handle to the desired posi-

tion for the job and secure the handle by screwing up tight.

7. Mounting the socket (Fig.2)

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.

HOW TO USE

1. Operation of switch (Fig.3)

The switch in this machine functions

as a motor switch and rotational direc-

tion selector switch. When the switch

is set to R indicated on the handle

cover, the motor rotates clockwise to

tighten the bolt. When the switch is set

to L, the motor rotates counterclock-

wise to loosen the bolt. When the

switch is released, the motor stops.

CAUTION:

Be sure to turn the switch OFF and wait until the motor completely stops be-

fore changing the direction of wrench revolution. Switching while the motor is

rotating will result in burning the motor.

2. Tightening and loosening bolts

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. Hold-

ing 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 preventing 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.

OPERATIONAL CAUTIONS

1. Confirm the line voltage (Fig. 4)

The available tightening torque is in-

fluenced by line voltage. Reduced line

voltage lowers the available tightening

torque.

For example, if you use a 120 V type

wrench on a 110 V line the available

tightening torque will be reduced to 70

to 90%. When extending the power

cord, use an extension cord which is

as short as possible. When the line volt-

age is low and a long extension cord is

needed a step up transformer should

be used. The relation between the line

voltage and the tightening torque are

shown in the figures.

2. Do not touch the bumper or hammer case during continuous operation

The bumper and hammer case become hot during continuous screw tightening

so be careful not to touch them at that time.

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

The optimum tightening torque for nuts and bolts differs with material and size

of the nuts and bolts. An excessively large tightening torque for a small bolt

may stretch or break the bolt. The tightening torque increases proportionally to

the operating time. Use the correct operating time for the bolt.

4. Selecting the socket to be matched to the bolt

Be sure to use a socket which is matched to the bolt to be tightened. Using an

improper socket will result not only 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 tight-

ness for fitting to the nut or anvil, consequently resulting in loss of tightening

torque.

Pay attention to wear of socket holes, and replace before further wear has

develops. Matching socket and bolt sizes are shown in Table 1.

The numerical value of a socket designation denotes the side-to-side distance

(S) of its hex. hole.

5. Holding the tool

Hold the Impact Wrench firmly with both hands by the body handle and the side

handle. 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 con-

firm 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) Line voltage:

The tightening torque decreases when the line voltage becomes low. (See

Fig. 4)

(2) Operating time:

The tightening torque increases when the operating time increases. But the tight-

ening torque does not increase above a certain value even if the tool is driven

for a long time. (See Fig. 4)

(3) Diameter of bolt:

The tightening torque differs with the diameter of the bolt as shown in Fig. 4.

Generally a larger diameter bolt has a 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 metal through which the

bolts are to be tightened.

(5) Using optional parts:

The tightening torque is reduced a little when an extension bar, universal joint

or a long socket is used.

(6) Clearance of the socket:

A worn or deformed hex. or a square-holed socket will not give an adequate tight-

ness to the fitting between the nut or anvil, consequently resulting in loss of tight-

ening torque.

Using an improper socket which does not match to the bolt will result in an insuf-

ficient tightening torque. Matching socket and bolt sizes are shown in Table 1.

MAINTENANCE AND INSPECTION

WARNING: Be sure to switch power OFF and disconnect the plug from the

receptacle during maintenance and inspection.

1. Inspecting the socket

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 socket holes periodically, and replace

with a new one if needed.

2. Inspecting the screws

Regularly inspect all screws and ensure that they are properly tightened. Should

any of the screws be loosened, retighten them immediately.

WARNING: Using this impact wrench with loosen 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

For your continued safety and electrical shock protection, carbon brush inspection

and replacement on this tool should ONLY be performed by a HITACHI

AUTHORIZED SERVICE CENTER.

5. Service and repairs

All quality power tools will eventually require servicing or replacement of parts

because of wear from normal use. To assure that only authorized replacement

parts will be used, all service and repairs must be performed by a HITACHI

AUTHORIZED SERVICE CENTER, ONLY.
