GENERAL SAFETY RULES

WARNING!

Read all instructions

Failure to follow all instructions listed below may result in

electric shock, ﬁ re and/or serious injury.

The term “power tool” in all of the warnings listed below

refers to your mains operated (corded) power tool or battery

operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) Work area

a) Keep work area clean and well lit.

Cluttered and dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of

ﬂ ammable liquids, gases or dust.

Power tools create sparks which may ignite the dust

of fumes.

c) Keep children and bystanders away while

operating a power tool.

Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet.

Never modify the plug in any way.

Do not use any adapter plugs with earthed

(grounded) power tools.

Unmodiﬁ ed plugs and matching outlets will reduce

risk of electric shock.

b) Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and

refrigerators.

There is an increased risk of electric shock if your

body is earthed or grounded.

c) Do not expose power tools to rain or wet

conditions.

Water entering a power tool will increase the risk of

electric shock.

d) Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges or

moving parts.

Damaged or entangled cords increase the risk of

electric shock.

e) When operating a power tool outdoors, use an

extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces the

risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating a power tool.

Do not use a power tool while you are tired

or under the inﬂ uence of drugs, alcohol or

medication.

A moment of inattention while operating power tools

may result in serious personal injury.

b) Use safety equipment. Always wear eye

protection.

Safety equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protection used for

appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in

the oﬀ position before plugging in.

Carrying power tools with your ﬁ nger on the switch or

plugging in power tools that have the switch on invites

accidents.

d) Remove any adjusting key or wrench before

turning the power tool on.

A wrench or a key left attached to a rotating part of the

power tool may result in personal injury.

e) Do not overreach. Keep proper footing and

balance at all times.

This enables better control of the power tool in

unexpected situations.

f) Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves

away from moving parts.

Loose clothes, jewellery or long hair can be caught in

moving parts.

g) If devices are provided for the connection of

dust extraction and collection facilities, ensure

these are connected and properly used.

Use of these devices can reduce dust related

hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct

power tool for your application.

The correct power tool will do the job better and safer

at the rate for which it was designed.

b) Do not use the power tool if the switch does not

turn it on and oﬀ .

Any power tool that cannot be controlled with the

switch is dangerous and must be repaired.

c) Disconnect the plug from the power source

before making any adjustments, changing

accessories, or storing power tools.

Such preventive safety measures reduce the risk of

starting the power tool accidentally.

d) Store idle power tools out of the reach of children

and do not allow persons unfamiliar with the

power tool or these instructions to operate the

power tool.

Power tools are dangerous in the hands of untrained

users.

e) Maintain power tools. Check for misalignment or

binding of moving parts, breakage of parts and

any other condition that may aﬀ ect the power

tools’ operation.

If damaged, have the power tool repaired before

use.

Many accidents are caused by poorly maintained

power tools.

f) Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp cutting

edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits

etc., in accordance with these instructions and

in the manner intended for the particular type

of power tool, taking into account the working

conditions and the work to be performed.

Use of the power tool for operations diﬀ erent from

intended could result in a hazardous situation.

5) Battery tool use and care

a) Ensure the switch is in the oﬀ position before

inserting battery pack.

Inserting the battery pack into power tools that have

the switch on invites accidents.

b) Recharge only with the charger speciﬁ ed by the

manufacturer.

A charger that is suitable for one type of battery pack

may create a risk of ﬁ re when used with another

battery pack.

c) Use power tools only with speciﬁ cally designated

battery packs.

Use of any other battery packs may create a risk of

injury and ﬁ re.

English

8

d) 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

burns or a ﬁ re.

e) Under abusive conditions, liquid may be ejected

from the battery; avoid contact. If contact

accidentally occurs, ﬂ ush with water. If liquid

contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation or

burns.

6) Service

a) Have your power tool serviced by a qualiﬁ ed

repair person using only identical replacement

parts.

This will ensure that the safety of the power tool is

maintained.

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.

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 recharged 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 ﬂ ickers 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.

PRIOR TO OPERATION

1. Mounting the blade

This unit employs a detachable mechanism that enables

mounting and removal of saw blades without the use of a

wrench or other tools.

(1) Turn on and oﬀ the switching trigger several times so

that the lever can jump out of the front cover completely.

Thereafter, turn oﬀ the switch and remove the battery.

(Fig. 5)

CAUTION

Be absolutely sure to keep the switch turned oﬀ and the

battery removed to prevent any accident.

(2) Push the lever in the direction of the arrow mark shown in

Fig. 6 marked on the lever (Fig. 6).

(3) Insert the saw blade all the way into the small slit of the

plunger tip with the lever pushing. You can mount this

blade either in the upward or downward direction (Fig. 7,

Fig. 8).

(4) When you release the lever, the spring force will return

the lever to the correct position automatically (Fig. 9).

(5) Pull the back of the saw blade two or three times by hand

and check that the blade is securely mounted. When

pulling the blade, you will know it is properly mounted if it

clicks and the lever moves slightly. (Fig. 10)

CAUTION

When pulling the saw blade, be absolutely sure to pull it

from the back. Pulling other parts of the blade will result

in an injury.

2. Dismounting the blade

(1) Turn on and oﬀ the switching trigger several times so

that the lever can jump out of the front cover completely.

Thereafter, turn oﬀ the switch and remove the battery.

(Fig. 5)

CAUTION

Be absolutely sure to keep the switch turned oﬀ and the

battery removed to prevent any accident.

(2) After you have pushed the lever in the direction of the

arrow mark shown in Fig. 6 and secured it, turn the blade

so it faces downward. The blade should fall out by itself.

If the blade doesn’t fall out, pull it out by hand.

CAUTION

Never touch the saw blade immediately after use. The

metal is hot and can easily burn your skin.

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 push

the lever in the direction of the arrow mark, 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. 11)

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) As shown in Fig. 12, carry out lubrication around the

blade holder on a periodic basis by use of cutting ﬂ uid,

etc.

NOTE:

Continued use of the tool without cleaning and lubricating

the area where the saw blade is installed can result in

some slack movement of the lever due to accumulated

sawdust and chips. Under the circumstances, pull a

rubber cap provided on the lever in the direction of an

arrow mark as shown in Fig. 13 and remove the rubber

cap from the lever. Then, clean up the inside of the

blade holder with air and the like and carry out suﬃ cient

lubrication.

The rubber cap can be ﬁ tted on if it is pressed ﬁ rmly onto

the lever. At this time, make certain that there exists no

clearance between the blade holder and the rubber cap,

and furthermore ensure that the saw-blade-installed area

can function smoothly.

CAUTION

Do not use any saw blade with a worn-out blade hole.

Otherwise, the saw blade can come oﬀ , resulting in

personal injury. (Fig. 14)

3. Moving the base

Loosen the set screw and move the base forward, as

shown in Fig. 15, Fig. 16. Tighten the set screw slightly,

ensure the base does not move back and forth, and

ﬁ rmly tighten the set screw. Ensure that the base does

not contact the blade.

4. Conﬁ rm that the battery is mounted correctly

HOW TO USE

CAUTION

○ Do not carry tools with your ﬁ nger on the switch. A

sudden startup can result in an unexpected injury.

○ 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 (refer to

Fig. 5).

○ Do not remove the front cover.

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

(refer to Fig. 5).

○ During use, press the base against the material while

cutting.

Vibration can damage the saw blade if the base is not

pressed ﬁ rmly against the workpiece.

Furthermore, a tip of the saw blade can sometimes

contact the inner wall of the pipe, damaging the saw

blade.

○ Select a saw blade of the most appropriate length.

Ideally, the length protruding from the base of the saw

blade after subtracting the stroke quantity should be

larger than the material (see Fig. 18 and Fig. 20).

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. 19, Fig. 21).

1. Switch operation

(1) Lock-oﬀ button

The tool is equipped with a lock-oﬀ button. To activate

the trigger lock, move the button to the right position.

Move the button to the left to operate the tool. (Fig. 17)

Always lock the switch when carrying or storing the tool

eliminate unintentional starting.

(2) Trigger switch

This tool is equipped with a variable speed controlled

trigger switch. The tool can be turned "ON" or "OFF" by

squeezing or releasing the trigger. The blade plunger

stroke rate can be adjusted from the minimum to

maximum nameplate stroke rate by the pressure you

apply to the trigger. Apply more pressure to increase the

speed and release pressure to decrease speed.

2. Cutting metallic materials

CAUTION

○ Press the base ﬁ rmly against the workpiece.

○ Never apply any unreasonable force to the saw blade

when cutting. Doing so can easily break the blade.

○ The motor can be locked sometimes, depending

on the combination of the material to be cut and the

blade. Whenever the motor gets locked, switch it oﬀ

immediately.

(1) Fasten a workpiece ﬁ rmly before operation. (Fig. 22)

(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. Cutting lumber

When cutting lumber, make sure that the workpiece is

fastened ﬁ rmly before beginning. (Fig. 23)

CAUTION

Never apply any unreasonable force to the saw blade

when cutting. Also remember to press the base against

the lumber ﬁ rmly.

4. Sawing curved lines

We recommend that you use the BI-METAL blade

mentioned in Table 6 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.

5. Plunge cutting

With this tool, you can perform plunge 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. 25, Fig. 27, and Fig. 29.

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 Table 6. 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. 24,

Fig. 25).

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

little by little (Fig. 26, Fig. 27).

(3) Hold the body ﬁ rmly until the saw blade completely cuts

into the material (Fig. 28, Fig. 29).

CAUTION

○ Avoid plunge cutting for metallic materials. This can

easily damage the blade.

○ Never pull the switch trigger while the tip of the saw blade

is pressed against the material. If you do so, the blade

can easily be damaged when it collides with the material.

○ Make absolutely sure that you cut slowly while holding

the body ﬁ rmly. If you apply any unreasonable force to

the saw blade during the cutting operation, the blade can

easily be damaged.

NOTE

The use of the battery BSL1430 and BSL1830 in

a cold condition (below 0 degree Centigrade) can

sometimes result in the weakened cutting torque and

reduced amount of work. This, however, is a temporary

phenomenon, and returns to normal when the battery

warms up.

6. About Remaining Battery Indicator

When pressing the remaining battery indicator switch,

the remaining battery indicator lamp lights and the

battery remaining power can be checked. (Fig. 30) When

releasing your ﬁ nger from the remaining battery indicator

switch, the remaining battery indicator lamp goes oﬀ . The

Table 4 shows the state of remaining battery indicator

lamp and the battery remaining power.

Table 4

State of lamp Battery Remaining Power

The battery remaining power is

enough.

The battery remaining power is a half.

The battery remaining power is nearly

empty.

Re-charge the battery soonest

possible.

As the remaining battery indicator shows somewhat

diﬀ erently depending on ambient temperature and

battery characteristics, read it as a reference.

NOTE:

○ Do not give a strong shock to the switch panel or break it.

It may lead to a trouble.

○ To save the battery power consumption, the remaining

battery indicator lamp lights while pressing the remaining

battery indicator switch.

SELECTION OF BLADES

To ensure maximum operating eﬃ ciency and results, it is

very important to select the appropriate blade best suited to

the type and thickness of the material to be cut.

NOTE:

Dimensions of the workpiece mentioned in the table

represent the dimensions when the mounting position

of the base is set nearest to the body of the Cordless

Reciprocating Saw. Caution must be exercised since

dimensions of the workpiece will become smaller if the

base is mounted far away from the body of the Cordless

Reciprocating Saw.

MAINTENANCE AND INSPECTION

CAUTION

Be sure to turned oﬀ the switch and remove the battery

before maintenance and inspection.

1. Inspecting the blade

Continued use of a dull or damaged blade will result in

reduced cutting eﬃ ciency 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

loose, retighten them immediately. Failure to do so could

result in serious hazard.

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. 31)

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. 999058.

5. Replacing carbon brushes

Take out the carbon brush by ﬁ rst removing the brush

cap and then hooking the protrusion of the carbon brush

with a ﬂ at head screw driver, etc., as shown in Fig. 33.

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 ﬁ nger as illustrated in Fig. 34. Lastly, install the

brush cap.

English

14

CAUTION

Be absolutely sure to insert the nail of the carbon brush

into the contact portion outside the brush tube (You can

insert whichever one of the two nails provided).

Caution must be exercised since any error in this

operation can result in the deformed nail of the carbon

brush and may cause motor trouble at an early stage.

6. Cleaning of the outside

When the Cordless Reciprocating Saw is stained, wipe

with a soft dry cloth or a cloth moistened with soapy

water. Do not use chloric solvents, gasoline or paint

thinner, as they melt plastics.

7. Storage

Store the Cordless Reciprocating Saw in a place in which

the temperature is less than 40°C, and out of reach of

children.

NOTE:

Make sure that the battery is fully charged when stored

for a long period (3 months or more). The battery with

smaller capacity may not be able to be charged when

used, if stored for a long period.
