SAFETY
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, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (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
flammable 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.
Unmodified 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 influence of drugs, alcohol or
medication.
3
English
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, nonskid 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 finger 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.

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 affect the power tool’s operation.
If damaged, have the power tool repaired
4
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 different
from those intended could result in a
hazardous situation.

DOUBLE INSULATION FOR SAFER
OPERATION
To ensure safer operation of this power tool, HITACHI
has adopted a double insulation design. “Double
insulation” means that two physically separated
insulation systems have been used to insulate the
electrically conductive materials connected to the power
supply from the outer frame handled by the operator.
Therefore, either the symbol “ ” or the words “Double
insulation” appear on the power tool or on the nameplate.
Although this system has no external grounding, you
must still follow the normal electrical safety precautions
given in this Instruction Manual, including not using the
power tool in wet environments.
To keep the double insulation system effective, follow
these precautions:
䡬
Only HITACHI AUTHORIZED SERVICE CENTER
should disassemble or assemble this power tool,
and only genuine HITACHI replacement parts
should be installed.
䡬
Clean the exterior of the power tool only with a
soft cloth moistened with soapy water, and dry
thoroughly.
Never use solvents, gasoline or thinners on plastic
components; otherwise the plastic may dissolve.

CAUTION:
䢇
Although this unit employs a powerful motor,
prolonged use at a low speed will increase the load
unduly and may lead to overheating. Properly
adjust the saw blade to allow steady, smooth
cutting operation, avoiding any unreasonable use
such as sudden stops during cutting operation.
HOW TO USE THE RECIPROCATING SAW
CAUTION:
䢇
Avoid carrying it plugged to the outlet with your
finger on the switch. A sudden startup can result
in an unexpected injury.
䢇
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.
䢇
Do not remove the front cover (refer to Fig. 2).
Be sure to hold the body from the top of the front
cover.
䢇
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.
䢇
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. 16 and Fig. 18).
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. 21
CAUTION:
Never apply any unreasonable force to the
saw blade when cutting. Also remember to
press the base against the lumber firmly.
3. Sawing curved lines
We recommend that you use the BIMETAL blade
mentioned in Page 14 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.
4. Plunge cutting
With this tool, you can perform pocket 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. 23,
Fig. 25, and Fig. 27. 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 Page 14. Be sure to use caution
during the cutting operation and observe the
following procedures.

Make absolutely sure that you cut slowly
while holding the body firmly. If you apply
any unreasonable force to the saw blade
during the cutting operation, the blade can
easily be damaged.
MAINTENANCE AND INSPECTION
WARNING:
1. Inspecting the blade
Continued use of a dull or damaged blade will
result in reduced cutting efficiency 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 loosened, retighten them immediately.
WARNING:
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 noto become damaged and/or wet
with oil or water.
12
Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance
and inspection.
Using this reciprocating saw with
loosen screws is extremely
dangerous.
4. Inspecting the carbon brushes (Fig. 28)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or
near the “wear limit”, it could result in motor
trouble. When an auto-stop carbon brush is
equipped, the motor will stop automatically. At that
time, replace both carbon brushes with new ones
which have the same carbon brush Numbers
shown in the figure. In addition, always keep
carbon brushes clean and ensure that they slide
freely within the brush holders.
English
Wear Limit

6. Service and repairs
Use HITACHI carbon brush No. 43 indicated
in Fig. 28.
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
All quality power tools will eventually require
servicing or replacement of parts because of wear
from normal use. To assure that only authorized
replacement parts will be used, all service and
repairs must be performed by a HITACHI
