injury, or may cause machine damage.
NOTE emphasizes essential information.
SAFETY
GENERAL SAFETY RULES
WARNING:
Read all instructions
Failure to follow all instructions listed below may result in electric shock, fire 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 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 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.
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.
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.
A moment of inattention while operating
power tools may result in serious personal
injury.
3
English
b) Use safety equipment. Always wear eye
protection.
Safety equipment such as dust mask, nonskid 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 finger 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
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 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 different
from intended could result in a hazardous
situation.
5) Service
a) Have your power tool serviced by a qualified
repair person using only identical
replacement parts.
This will ensure that the safety of the power
tool is maintained.
–WARNING–
To reduce the risk of injury, user must read
instruction manual.
SAFETY INSTRUCTIONS FOR ALL SAWS
DANGER!
a) Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or
motor housing.
If both hands are holding the saw, they cannot be
cut by the blade.
b) Do not reach underneath the workpiece.
The guard cannot protect you from the blade below
the workpiece.
c) Adjust the cutting depth to the thickness of the
workpiece.
Less than a full tooth of the blade teeth should be
visible below the workpiece.
d) Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable
platform.
It is important to support the work properly to
minimize body exposure, blade binding, or loss of
control.
e) Hold power tool by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a “live” wire will also make exposed
metal parts of the power tool “live” and shock the
operator.
f) When ripping always use a rip fence or straight
edge guide.
This improves the accuracy of cut and reduces the
chance of blade binding.
4
English
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware of
the saw will run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade washers
or bolt.
The blade washers and bolt were specially
designed for your saw, for optimum performance
and safety of operation.
䡬
Never use any abrasive wheels
Burst of abrasive wheel cause serious injury of
operator or persons around the working area.
d) Support large panels to minimize the risk of blade
pinching and kickback.
Large panels tend to sag under their own weight.
Supports must be placed under the panel on both
sides, near the line of cut and near the edge of the
panel.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut.
If blade adjustment shifts while cutting, it may
FURTHER SAFETY INSTRUCTIONS FOR
ALL SAWS
Causes and operator prevention of kickback:
–Kickback is a sudden reaction to a pinched, bound
or misaligned saw blade, causing an uncontrolled
saw to lift up and out of the workpiece toward the
operator.
– When the blade is pinched or bound tightly by the
kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back toward the
operator.
–If the blade becomes twisted or misaligned in the
cut, the teeth at the back edge of the blade can dig
into the top surface of the wood causing the blade
to climb out of the kerf and jump back toward the
operator.
cause binding and kickback.
g) Use extra caution when making a “plunge cut”
into existing walls or other blind areas.
The protruding blade may cut objects that can
cause kickback.
SAFETY INSTRUCTIONS FOR SAWS WITH
INNER PENDULUM GUARD
a) Check lower guard for proper closing before each
use. Do not operate the saw if lower guard does
not move freely and close instantly. Never clamp
or tie the lower guard into the open position.
If saw is accidentally dropped, lower guard may
be bent.
Raise the lower guard with the retracting handle
and make sure it moves freely and does not touch
the blade or any other part, in all angles and depth
of cut.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below.
b) Check the operation of the lower guard spring. If
the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to
a) Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade, but
not in line with the blade.
Kickback could cause the saw to jump backwards,
but kickback forces can be controlled by the
operator, if proper precautions are taken.
b) When blade is binding, or when interrupting a cut
for any reason, release the trigger and hold the
saw motionless in the material until the blade
comes to a complete stop.
Never attempt to remove the saw from the work
or pull the saw backward while the blade is in
motion or kickback may occur.
Investigate and take corrective actions to eliminate
the cause of blade binding.
c) When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw teeth
are not engaged into the material.
damaged parts, gummy deposits, or build-up of
debris.
c) Lower guard should be retracted manually only
for special cuts such as “plunge cuts” and
“compound cuts”. Raise lower guard by retracting
handle and as soon as blade enters the material,
the lower guard must be released.
For all other sawing, the lower guard should
operate automatically.
d) Always observe that the lower guard is covering
the blade before placing saw down on bench or
floor.
An unprotected, coasting blade will cause the saw
to walk backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to stop
after switch is released.
If saw blade is binding, it may walk up or kickback
from the workpiece as the saw is restarted.

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.

ASSEMBLY AND OPERATION
APPLICATIONS
䡬
Cutting Various types of wood.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized
conforms to the power source requirements
specified on the product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the
plug is connected to a receptacle while the switch
is in the ON position, the power tool will start
operating immediately and can cause serious injury.
3. Extension cord
When the work area is far away from the power
source, use an extension cord of sufficient
thickness and rated capacity. The extension cord
should be kept as short as practicable.
WARNING:
Damaged cord must be replaced or repaired.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the
receptacle must be repaired. Contact a licensed
electrician to make appropriate repairs.
If such a faulty receptacle is used, it may cause
overheating, resulting in a serious hazard.
5. Confirming condition of the environment:
Confirm that the work site is placed under appropriate
conditions conforming to prescribed precautions.
6. Prepare a wooden workbench (Fig. 2)
Since the saw blade will extend beyond the lower
surface of the work piece, place the work piece on
a workbench when cutting. If a square block is
utilized as a workbench, select level ground to
ensure it is properly stabilized. An unstable
workbench will result in hazardous operation.
Work piece
Workbench
Base
Saw blade
CAUTION:
To avoid possible accident, always ensure that the
portion of work piece remaining after cutting is
securely anchored or held in position.
7. Check if lever (A)s are tightened.
If the lever (A) to adjust cutting depth (Fig. 3) and
lever (A) to adjust angle of inclination (Fig. 4) are
loose, injury can result. Make sure that they are
tightened securely.
8. Check performance of safety cover
WARNING:
Make absolutely sure that the safety cover is not
fixed. Also, check and see if it can move smoothly.
If the saw blade is kept exposed injury can result.
The lower guard (refer to Fig. 1) serves to protect
your body from coming into contact with the saw
blade. Make absolutely certain that the cover
smoothly performs to cover the saw blade. If the
safety cover should not move smoothly, never use
it without repairing it.
In such a case, get in touch with the store where
you bought the circular saw or the HITACHI
Authorized Service Center for necessary repair.
9. Eye protection
When you use the tool, make certain that you wear
eye protection.
10. Check if saw blade is tightened
Refer to [mounting and dismounting the saw
blade] in Page 12, and make sure that the flange
bolt is tightened securely.
11. Check for proper operation of the brake.
Your saw has an automatic electric brake which is
designed to stop the blade from coasting in about
3 seconds, after you release the trigger switch. It
is useful when making certain cuts in wood where
a coasting blade would result a wide imprecise cut.
Occasionally, under certain conditions, the brake
will not function properly and won't stop the saw
in the 3 seconds discussed above.
If this condition persists, turn the saw on and off
four or five times. If the brake still does not stop
the blade in about 3 seconds, the problem may be
worn brushes. Replace the brushes and try the saw
again. If the problem still persists, have the tool
serviced at a HITACHI AUTHRIZED SERVICE
CENTER.
