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.
5
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.

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.
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.
16
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.
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.
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)
18
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:
Avoid carrying it with your finger 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.
Do not remove the front cover (refer to Fig. 5).
Be sure to hold the body from the top of the front
cover.
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.
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.

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:
Press the base firmly 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 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.
