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.

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.
English

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.
8. Service parts list
CAUTION
Repair, modifi cation and inspection of Hitachi Power
Tools must be carried out by a Hitachi Authorized Service
Center.
This Parts List will be helpful if presented with the tool to
the Hitachi Authorized Service Center when requesting
repair or other maintenance.
