GENERAL POWER TOOL SAFETY
WARNINGS
WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in
electric shock, fi re and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless)
power tool.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or 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
or 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.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply.
Use of an RCD 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 personal protective equipment. Always
wear eye protection.
Protective equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the
switch is in the off position before connecting to
power source and/or battery pack, picking up or
carrying the tool.
Carrying power tools with your fi nger on the switch
or energising 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 dust collection 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 and/
or the battery pack from the power tool 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 toolʼs 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,
taking into account the working conditions and
the work to be performed.
Use of the power tool for operations diff erent from
those intended could result in a hazardous situation.
5) Battery tool use and care
a) 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.
b) 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.
2
Page 3
c) 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.
d) 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.
PRECAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of
children and infi rm persons.
CORDLESS RECIPROCATING SAW
SAFETY WARNINGS
1. Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring.
Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
ADDITIONAL SAFETY WARNINGS
1. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
2. Never disassemble the rechargeable battery and
charger.
3. Never short-circuit the rechargeable battery.
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
4. Do not dispose of the battery in fi re. If the battery is burnt,
it may explode.
5. Bring the battery to the shop from which it was purchased
as soon as the post-charging battery life becomes too
short for practical use. Do not dispose of the exhausted
battery.
6. Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or infl ammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
7. When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch. Please leave
it without using it for approximately 15 minutes.
8. Wear earplugs to protect your ears during operation.
9. Do not touch the blade during or immediately after
operation. The blade becomes very hot during operation
and could cause serious burns.
10. Always hold the body handle and front cover of the
power tool fi rmly. Otherwise the counterforce produced
may result in inaccurate and even dangerous operation.
11. Remove the battery from tool or place the switch in the
locked or off position before making any adjustments,
changing accessories, or storing the tools.
12. Mounting and dismounting the blade
○ Be absolutely sure to keep the switch turned off and the
battery removed to prevent any accident.

○ 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. 3)
○ 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.
○ 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. 4)
○ 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.
○ As shown in Fig. 5, carry out lubrication around the
blade holder on a periodic basis by use of cutting fl uid,
etc.
○ 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. 5 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.
○ Do not use any saw blade with a worn-out blade hole.
Otherwise, the saw blade can come off , resulting in
personal injury.
13. When setting the base position, be absolutely sure to
keep the switch turned off and the battery removed to
prevent any accident.
14. Make sure that the battery is installed fi rmly. If it is at all
loose it could come off and cause an accident.
15. Do not carry tools with your fi nger on the switch. A
sudden startup can result in an unexpected injury.
16. 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.
17. Do not remove the front cover which will cause in an
injury.
Be sure to hold the body from the top of the front cover.
18. During use, press the base fi rmly against the workpiece.
19. Select a saw blade of the most appropriate length.
Ideally, the length protruding from the base of the saw
blade after su
larger than the material.
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. 8)
20. Never apply any unreasonable force to the saw blade
when cutting. Doing so can easily break the blade.
21. 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.
22. Fasten a workpiece fi rmly before operation. (Fig. 9)
23. When cutting metallic materials, use proper machine
oil (turbine oil, etc.). When not using liquid machine oil,
apply grease over the workpiece.
The service life of the saw blade will be drastically
shortened if you don’t use machine oil.
24. Delay the feed speed when cutting the material into
small circular arcs. An unreasonably fast feed may break
the blade.
btracting the stroke quantity should be
Page 4
25. Avoid plunge cutting for metallic materials. This can
easily damage the blade.
26. 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.
27. 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.
28. The use of the battery 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.

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. 12)
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. 999068.
5. Replacing carbon brushes (Fig. 12)
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.
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. Lastly, install the brush cap.

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 on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
7. Storage
Store the power tool in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
Important notice on the batteries for the Hitachi
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modifi ed (such as
disassembly and replacement of cells or other internal
parts).
NOTE
Due to HITACHI’s continuing program of research and
development, the specifi cations herein are subject to
change without prior notice.
