IMPORTANT INFORMATION

Read and understand all of the operating instructions, safety precautions and warnings in

the Instruction Manual before operating or maintaining this power tool.

Most accidents that result from power tool operation and maintenance are caused by the

failure to observe basic safety rules or precautions. An accident can often be avoided by

recognizing a potentially hazardous situation before it occurs, and by observing appropriate

safety procedures.

Basic safety precautions are outlined in the “SAFETY” section of this Instruction Manual and

in the sections which contain the operation and maintenance instructions.

Hazards that must be avoided to prevent bodily injury or machine damage are identified by

WARNINGS on the power tool and in this Instruction Manual.

Never use this power tool in a manner that has not been specifically recommended by

HITACHI, unless you first confirm that the planned use will be safe for you and others.

MEANINGS OF SIGNAL WORDS

WARNING indicates a potentially hazardous situations which, if ignored, could result in

serious personal injury.

CAUTION indicates a hazardous situations which, if ignored, could result in moderate

personal injury, or could cause machine damage.

NOTE emphasizes essential information.

English

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) Don’t 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.

(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.

English

(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 protective glasses. Dust mask, nonskid safety

shoes, hard hat, or ear plugs 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 form 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 tools 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 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.

English

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.

WHEN THE BLADE IS BROKEN

Even when the saw blade is broken and remains

inside the small slit of the plunger, it should fall out

if you turn the holder sleeve in the direction of the

arrow mark, secure the holder sleeve, and face the

blade downward. If it doesn’t fall out itself, take it

out using the procedures explained below.

(1) If a part of the broken saw blade is sticking out of

the small slit of the plunger, pull out the

protruding part and take the blade out.

(2) If the broken saw blade is hidden inside the

small slit, hook the broken blade using a tip of

another saw blade and take it out. (Fig. 8)

MAINTENANCE AND INSPECTION OF SAW

BLADE MOUNT

(1) After use, blow away sawdust, earth, sand,

moisture, etc., with air or brush them away with

a brush, etc., to ensure that the blade mount can

function smoothly.

(2) Periodically lubricate the saw blade mount with

machine oil through the semicircular slit at a

state where the holder sleeve is turned in the

direction of the arrow mark shown in Fig. 3. (Fig.

NOTE:

If the saw blade mount is used without proper cleaning and lubrication, the rotation

of the holder sleeve may be hampered by sawdust and particles of dust, disabling you

to remove the saw blade with your fingers.

In such a case, hold the periphery of the holder sleeve lightly using a pair of pliers and

the like, and turn the holder sleeve to left and right little by little. After the saw blade

has been successfully removed, be absolutely sure to clean it up with air, etc., carry

out proper lubrication, and then check and see if the saw blade mount can function

smoothly.

8. Adjusting the base

This unit employs a mechanism that can adjust the

base mounting position in three stages without the

use of a wrench or other tools.

(1) Press a pushbutton. When you do this, a base

lever will jump out to prepare the base for

adjustment (Fig. 10)

(2) Push up the base tip and jog the base back and

forth. (Fig. 11)

(3) You can adjust the base position in three stages.

Move the base at an interval of about 15 mm,

find the position where the base hooks, and

press in the base lever with your fingers. The

base is secured when you hear the clicking

sound. (Fig. 12)

9. Adjusting the blade reciprocating speed

This unit has a built-in electronic control circuit that

makes it possible to adjust the variable speed of the

saw blade either both by pulling a switching trigger

or turning a dial. (Fig. 13)

(1) If you pull the trigger further in, the speed of the

blade accelerates. Begin cutting at a low speed

to ensure the accuracy of your target cut position.

Once you’ve obtained a sufficient cutting depth,

increase the cutting speed.

(2) On the dial scale, “5” is the maximum speed and

“1” the minimum. The high speed is generally

suitable for soft materials such as wood, and the

low speed is suitable for hard materials such as

metal. We recommend that you use the following

as a rough guide in selecting the suitable speed

for the materials you are cutting.

CAUTION:

䡬 When cutting at low speed (scale of 1 – 2), never cut a wooden board more than

25/64" (10 mm) thick or a mild steel plate more than 5/64" (2 mm) thick. The load on

the motor can result in overheating and damage.

䡬 Although this unit employs a powerful motor, prolonged use at a low speed will

increase the load unduly and may lead to overheating. Properly adjust the saw blade

to allow steady, smooth cutting operation, avoiding any unreasonable use such as

sudden stops during cutting operation.

Adjusting the swing cutting operation

Two cutting systems can be selected with this

unit. The first is straight cutting, in which the

saw blade is moved linearly, and the second is

the swing cutting, in which the saw blade is

swung like a pendulum. (Fig. 14, Fig. 15)

(1) Straight cutting

You can perform straight cutting by setting

the change lever widthwise. Straight cutting

should normally be performed when cutting

hard materials such as metal, etc. (Fig. 14)

(2) Swing cutting

You can perform swing cutting by setting

the change lever lengthways. Swing cutting

should normally be performed when cutting

soft materials such as wood, etc.

Swing cutting is efficient since the saw blade

forcibly bites into the material. (Fig. 15)

CAUTION:

䡬 Even for soft materials, you should perform straight cutting if you wish to make

curved or clean cuts.

䡬 Dust and dirt accumulated on the change lever section can degrade the function of

the change lever. Periodically clean the change lever section.

HOW TO USE THE RECIPROCATING SAW

CAUTION:

䡬 Avoid carrying it plugged to the outlet with your finger on the switch. A sudden startup

can result in an unexpected injury.

䡬 Be careful not to let sawdust, earth, moisture, etc., enter the inside of the machine

through the plunger section during operation. If sawdust and the like accumulate in the

plunger section, always clean it before use.

䡬 Do not remove the front cover (refer to Fig. 2).

Be sure to hold the body from the top of the front cover.

䡬 During use, press the base against the material while cutting.

Vibration can damage the saw blade if the base is not pressed firmly against the

workpiece.

Furthermore, a tip of the saw blade can sometimes contact the inner wall of the pipe,

damaging the saw blade.

Fig. 15

Swing Cutting

Change Lever

Fig. 14

Straight Cutting

English

䡬 Select a saw blade of the most appropriate

length. Ideally, the length protruding from the

base of the saw blade after subtracting the

stroke should be larger than the material (see

Fig. 16 and Fig. 18).

If you cut a large pipe, large block of wood, etc.,

that exceeds the cutting capacity of a blade;

there is a risk that the blade may contact with

the inner wall of the pipe, wood, etc., resulting

in damage. (Fig. 17, Fig. 19)

䡬 To maximize cutting efficiency for the materials

you are using and working conditions, adjust

the speed of the saw blade and the switching to

swing cutting.

1. Cutting metallic materials

CAUTION:

䡬 Press the base firmly against the workpiece.

䡬 Never apply any unreasonable force to the

saw blade when cutting. Doing so can easily

break the blade.

(1) Fasten a workpiece firmly before operation.

(Fig. 20)

(2) When cutting metallic materials, use proper

machine oil (turbine oil, etc.). When not

using liquid machine oil, apply grease over

the workpiece.

CAUTION: The service life of the saw blade

will be drastically shortened if

you don’t use machine oil.

(3) Use the dial to adjust the speed of the saw

blade to suit your working conditions and

materials.

(4) You can cut smoothly if you set the change

lever position to straight cutting (Fig. 14).

2. Cutting lumber

(1) When cutting lumber, make sure that the

workpiece is fastened firmly before

beginning. (Fig. 21)

(2) You can cut efficiently if the speed of the saw

blade is set to dial scale “5”.

(3) You can cut efficiently if the change lever

position is set to swing cutting (Fig. 15).

Alternatively, you can cut cleanly if the

change lever position is set to straight cutting

(Fig. 14).

CAUTION: Never apply any unreasonable

force to the saw blade when

cutting. Also remember to press

the base against the lumber

firmly.

3. Sawing curved lines

We recommend that you use the BIMETAL

blade mentioned in Page 19 for the saw blade

since it is tough and hardly breaks.

CAUTION: Delay the feed speed when cutting the material into small circular arcs.

An unreasonably fast feed may break the blade.

4. Plunge cutting

With this tool, you can perform pocket cutting

on plywood panels and thin board materials.

You can carry out pocket cutting quite easily

with the saw blade installed in reverse as

illustrated in Fig. 23, Fig. 25, and Fig. 27. Use the

saw blade that is as short and thick as possible.

We recommend for this purpose that you use

BI-METAL Blade No. 132 mentioned in Page 19.

Be sure to use caution during the cutting

operation and observe the following procedures.

(1) Press the lower part (or the upper part) of the

base against the material. Pull the switch

trigger while keeping the tip of the saw

blade apart from the material. (Fig. 22, Fig.

23)

(2) Raise the handle slowly and cut in with the

saw blade little by little. (Fig. 24, Fig. 25)

(3) Hold the body firmly until the saw blade

completely cuts into the material. (Fig. 26,

Fig. 27)

Fig. 22

Fig. 23

Fig. 24

Fig. 25

Fig. 21

English

CAUTION:

䡬 Avoid plunge cutting for metallic materials.

This can easily damage the blade.

䡬 Never pull the switch trigger while the tip of

the saw blade tip is pressed against the

material. If you do so, the blade can easily

be damaged when it collides with the

material.

䡬 Make absolutely sure that you cut slowly

while holding the body firmly. If you apply

any unreasonable force to the saw blade

during the cutting operation, the blade can

easily be damaged.

MAINTENANCE AND INSPECTION

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

during maintenance and inspection.

1. Inspecting the blade

Continued use of a dull or damaged blade will result in reduced cutting efficiency and may

cause overloading of the motor. Replace the blade with a new one as soon as excessive

abrasion is noted.

2. Inspecting the mounting screws

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

Should any of the screws be loosened, retighten them immediately.

WARNING: Using this reciprocating saw 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 noto become damaged and/or wet with oil or water.

4. Inspecting the carbon brushes (Fig. 28)

The Motor employs carbon brushes which

are consumable parts. When they become

worn to or near the “wear limit”, it could

result in motor trouble. When an auto-stop

carbon brush is equipped, the motor will

stop automatically. At that time, replace

both carbon brushes with new ones which

have the same carbon brush Numbers shown

in the figure. In addition, always keep carbon

brushes clean and ensure that they slide

freely within the brush holders.

NOTE: Use HITACHI carbon brush No. 43 indicated in Fig. 28.

5. Replacing carbon brushes

Disassemble the brush caps with a slotted-head screwdriver. The carbon brushes can

then be easily removed.

6. 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.

7. Service parts list

CAUTION: Repair, modification and inspection of Hitachi Power Tools must be carried

out by an Hitachi Authorized Service Center.

This Parts List will be helpful if presented with the tool to the Hitachi

tion 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.

AVERTISSEMENT:

La poussière résultant d'un ponçage, d'un sciage, d'un meulage, d'un perçage ou

de toute autre activité de construction renferme des produits chimiques qui sont

connus par l'Etat de Californie pour causer des cancers, des défauts de naissance

et autres anomalies de reproduction. Nous énumérons ci-dessus certains de ces

produits chimiques:

● Plomb des peintres à base de plomb,

● Silice cristalline des briques et du ciment et autres matériaux de maçonnerie, et

● Arsenic et chrome du bois d'oeuvre traité chimiquement.

Le risque d'exposition à ces substances varie en fonction de la fréquence d'exécution

de ce genre de travail. Pour réduire l'exposition à ces produits chimiques, travailler

dans un lieu bien ventilé, et porter un équipement de protection agréé, par exemple

un masque anti-poussière spécialement conçu pour filter les particules microscopiques.

ADVERTENCIA:

Alogunos polvos creados por el lijado mecámico, el aserrado, el esmerilado, el

taladrado y otras actividades de construcción contienen sustancias químicas conocidas

por le Estado de California como agentes cancerígenos, defectos congénitos y otros

daños reproductores. Algunos ejemplos de estas sustancias químicas son:

● El plomo de las pinturas a base de plomo,

● El sílice cristalino de los ladrillos y cemento y otros productos de mampostería, y

● El arsénico y el cromo de la madera tratada químicamente.

El riesgo resultante de la exposición varía según la frecuencia con que se realiza

este tipo de trabajo. Para reducir la exposicíon a esta sustancias químicas: trabaje

en un lugar bien ventilado y realice el trabajo utilizando el equipamiento apropiado,

tal como las máscares para el polvo especialmente diseñados para eliminar las

partículas minúsculas.
