SAFETY
GENERAL SAFETY RULES
WARNING: Read and understand all instructions.
Failuretofollowall instructions listed below,mayresultin 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) Double Insulated tools are equipped with a polarized plug (one blade is wider than
the other.) This plug will fit in a polarized outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified
electrician to install a polarized outlet. Do not change the plug in any way. Double
Insulation eliminates the need for the three wire grounded power cord and
grounded power supply system.
(2) Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
(3) Don’t expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
(4) Do not abuse the cord. Never use the cord to carry the tools or pull the plug from a
receptacle. Keep cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock.
(5) When operating a power tool outside, use an outdoor extension cord marked “W-A”
or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.
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. Looseclothes, jewelry, orlonghair
can be caught in moving parts.
(3) Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools that have the switch on invites accidents.

English
5
(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 enables better control of the tool in unexpected situations.
(6) Use safety equipment. Always wear protective glasses. Dust mask, nonskid safety
shoes, hard hat, or ear plugs must be used for appropriate conditions.
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 the plug form the power source before making any adjustments,
changing accessories, or storing the tool. 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) 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.
(7) Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tools operation. If damaged, have the tool serviced
before using. Many accidents are caused by poorly maintained tools.
(8) 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 qualified repair personnel. 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.

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
fromtheouterframe handled bytheoperator. Therefore, eitherthesymbol“ ” or thewords
“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.

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. 8)
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. 3. (Fig.
9)
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.
8. Adjusting the base
This unit employs a mechanism that can adjust the
base mounting position in three stages without the
use of a wrench or other tools.
(1) Press a pushbutton. When you do this, a base
lever will jump out to prepare the base for
adjustment (Fig. 10)

(2) Push up the base tip and jog the base back and
forth. (Fig. 11)
(3) You can adjust the base position in three stages.
Move the base at an interval of about 15 mm,
find the position where the base hooks, and
press in the base lever with your fingers. The
base is secured when you hear the clicking
sound. (Fig. 12)
9. Adjusting the blade reciprocating speed
This unit has a built-in electronic control circuit that
makes it possible to adjust the variable speed of the
saw blade either both by pulling a switching trigger
or turning a dial. (Fig. 13)
(1) If you pull the trigger further in, the speed of the
blade accelerates. Begin cutting at a low speed
toensuretheaccuracyofyourtargetcutposition.
Once you’ve obtained a sufficient cutting depth,
increase the cutting speed.
(2) On the dial scale, “5” is the maximum speed and
“1” the minimum. The high speed is generally
suitable for soft materials such as wood, and the
low speed is suitable for hard materials such as
metal.We recommendthatyouusethefollowing
as a rough guide in selecting the suitable speed
for the materials you are cutting.
CAUTION:
䡬When cutting at low speed (scale of 1 – 2), never cut a wooden board more than
25/64" (10 mm) thick or a mild steel plate more than 5/64" (2 mm) thick. The load on
the motor can result in overheating and damage.
䡬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.

10. Adjusting the swing cutting operation
Two cutting systems can be selected with this
unit. The first is straight cutting, in which the
saw blade is moved linearly, and the second is
the swing cutting, in which the saw blade is
swung like a pendulum. (Fig. 14, Fig. 15)
(1) Straight cutting
You can perform straight cutting by setting
the change lever widthwise. Straight cutting
shouldnormallybe performedwhencutting
hard materials such as metal, etc. (Fig. 14)
(2) Swing cutting
You can perform swing cutting by setting
the change lever lengthways. Swing cutting
shouldnormallybe performedwhencutting
soft materials such as wood, etc.
Swingcuttingis efficientsincethe sawblade
forcibly bites into the material. (Fig. 15)
CAUTION:
䡬Even for soft materials, you should perform straight cutting if you wish to make
curved or clean cuts.
䡬Dust and dirt accumulated on the change lever section can degrade the function of
the change lever. Periodically clean the change lever section.
HOW TO USE THE RECIPROCATING SAW
CAUTION:
䡬Avoid carrying it plugged to the outlet 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. 2).
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.
Fig. 15

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. 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. 17, Fig. 19)
䡬Tomaximizecutting efficiencyforthe materials
you are using and working conditions, adjust
the speed of the saw blade and the switching to
swing cutting.
1. Cutting metallic materials
CAUTION:
䡬Pressthebase firmlyagainstthe workpiece.
䡬Never apply any unreasonable force to the
sawbladewhen cutting. Doingso can easily
break the blade.
(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) Use the dial to adjust the speed of the saw
blade to suit your working conditions and
materials.
(4) You can cut smoothly if you set the change
lever position to straight cutting (Fig. 14). Fig. 19

(Fig. 14).
CAUTION: Never apply any unreasonable
force to the saw blade when
cutting.Alsoremember to press
the base against the lumber
firmly.
3. Sawing curved lines
We recommend that you use the BIMETAL
blade mentioned in Page 19 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 19.
Be sure to use caution during the cutting
operationandobservethefollowing procedures.
(1) Pressthelowerpart (or theupperpart) of the
base against the material. Pull the switch
trigger while keeping the tip of the saw
blade apart from the material. (Fig. 22, Fig.
23)
(2) Raise the handle slowly and cut in with the
saw blade little by little. (Fig. 24, Fig. 25)
(3) Hold the body firmly until the saw blade
