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.

Dial
Graduation
Fig. 15
(1) If you pull the trigger further in, the
speed of the blade accelerates. Begin
cutting at a low speed to ensure the
accuracy of your target cut position.
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 recommend that
you use the following as a rough guide
in selecting the suitable speed for the
materials you are cutting.
Example of materials Recommended
to be cut dial scale
Mild steel pipes /
cast-iron tubes / 2 – 4
L-shaped angle steel
Wood / wood with nails
driven in
Stainless steel 1 – 3
Aluminum / brass / copper 2 – 4
Plaster board 4 – 5
Plastic / fiber board 1 – 3

speed
12
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
English
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. 16, Fig. 17)
(1) Straight cutting
You can perform straight cutting by
setting the change lever widthwise.
Straight cutting should normally be
performed when cutting hard
materials such as metal, etc. (Fig. 16)
Straight cutting
Fig. 16
(2) Swing cutting
You can perform swing cutting by
setting the change lever lengthways.
Swing cutting should normally be
performed when cutting soft materials
such as wood, etc.
Swing cutting is efficient since the
saw blade forcibly bites into the
material. (Fig. 17)
Swing cutting
Fig. 17
Change lever
Change lever
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.
䡬 When performing swing cutting, use
a saw with straight blade. If a saw
with curved blade is used, the saw
blade may be broken or the unit may
be damaged.
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).
Hold firmly the front cover by hand to
operate.
But, do not extend your hand or finger
beyond the flange (see Fig.18) of front
cover to avoid an injury.
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.
13
English
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. 18 and Fig. 19).
Flange of front cover

䡬 To maximize cutting efficiency for the
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 Press the base firmly against the
workpiece.
䡬 Never apply any unreasonable force to
the saw blade when cutting. Doing so
can easily break the blade.
(1) Fasten a workpiece firmly before
operation. (Fig.22)
Fig. 19
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. 20, Fig. 21)
Fig. 20
14
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) Use the dial to adjust the speed of the
saw blade to suit your working
conditions and materials.
English
(4) You can cut smoothly if you set the
change lever position to straight
cutting (Fig. 16).
2. Cutting lumber
(1) When cutting lumber, make sure that
the workpiece is fastened firmly
before beginning. (Fig. 23)
Fig. 23
(2) You can cut efficiently if the speed of
the saw blade is set to dial scale “5”.
(3) You can cut efficiently if the change
lever position is set to swing cutting
(Fig. 17). Alternatively, you can cut
cleanly if the change lever position is
set to straight cutting (Fig. 16).
CAUTION:
Never apply any unreasonable force
to the saw blade when cutting. Also
remember to press the base against
the lumber firmly.
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. 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 Page 18. 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)
Fig. 24
3. Sawing curved lines
We recommend that you use the
BIMETAL blade mentioned in Page 18
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.

CAUTION:
䡬 Avoid plunge cutting for metallic
materials. This can easily damage
the blade.
䡬 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.
䡬 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: Be sure to switch power OFF and disconnect the plug from the
receptacle during maintenance and inspection.
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: Using this reciprocating
saw with loosen screws
is extremely dangerous.
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.
4. Inspecting the carbon brushes (Fig. 30)
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.

5. Replacing carbon brushes
Disassemble the brush caps with a
slotted-head screwdriver. The carbon
brushes can then be easily removed.
6. Service and repairs
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
AUTHORIZED SERVICE CENTER, ONLY.
