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 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.

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 tool's operation. If damaged, have the tool

serviced by a HITACHI authorized service center 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 a HITACHI authorized service center. 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.

䡬 Regarding the temperature of the rechargeable battery.

The temperatures for rechargeable batteries are as shown in the table below, and

batteries that have become hot should be cooled for a while before being recharged.

䡬 Regarding recharging time

Table 4 shows the recharging time required according to the type of battery.

Table 4 Recharging time (approx. min.) at 68°F(20°C)

NOTE: The recharging time may vary according to ambient temperature and power

source voltage.

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.

English

5. Remove the battery from the battery charger.

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

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.

䡬 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.

䡬 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 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.

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.

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 holder sleeve 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) Turn the holder sleeve in the direction of the

arrow mark shown in Fig. 6 marked on the holder

sleeve. If you turn the holder sleeve halfway you

will be able to secure it automatically. (Fig. 6)

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

slit of the plunger tip. You can mount this blade

either in the upward or downward direction. (Fig.

7, Fig. 8)

(4) Pull the holder sleeve back slightly in the

direction of the arrow mark shown in Fig. 9 (in

the direction opposite to the arrow marked on

the holder sleeve). When you do this, the spring

force will return the holder sleeve to the correct

position automatically. There is no need to

fasten the holder sleeve at this time. (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 holder

sleeve 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 holder sleeve can jump out of

the front cover completely. Thereafter, turn off

the switch and remove the battery. (Fig. 5)

English

CAUTION:Be absolutely sure to keep the switch

turned off and the battery removed

to prevent any accident.

(2) After you have turned the holder sleeve 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

does'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 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. 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)

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. 6. (Fig. 12)

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.

3. Moving the base

Loosen the set screw and move the base forward,

as shown in Fig. 13. Tighten the set screw slightly,

ensure the base does not move back and forth, and

firmly tighten the set screw. Ensure that the base

does not contact the blade.

4. Confirm that the battery is mounted correctly.

HOW TO USE THE CORDLESS RECIPROCATING SAW

CAUTION:

䡬 Avoid carrying it 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. 5).

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.

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. 14 and Fig. 16).

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.

1. Switch operation

(1) Lock-off button

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

acivate the trigger lock, move the button to the right

positon. Move the button to the left to operate the

tool. (Fig. 18, Fig. 19)

English

CAUTION: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:

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.

䡬 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 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. Cutting lumber

When cutting lumber, make sure that the workpiece

is fastened firmly before beginning. (Fig. 21)

CAUTION:Never apply any unreasonable force

to the saw blade when cutting. Also

remember to press the base against

the lumber firmly.

4. Sawing curved lines

We recommend that you use the BIMETAL

blade mentioned in Page 26 for the saw blade

since it is tough and hardly breaks.
