tool is maintained.
SPECIFIC SAFETY RULES AND SYMBOLS
1. DANGER: 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.
2. Do not reach underneath the workpiece.
The guard cannot protect you from the blade below
the workpiece.
01Eng_C7SB2_US 7/29/11, 3:23 PM4
English
5
3. 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.
4. 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.
5. 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.
6. When ripping always use a rip fence or straight
edge guide.
This improves the accuracy of cut and reduces the
chance of blade binding.
7. 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.
8. 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.
9. 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.
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:
10. 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.
11. 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.
12. When restarting a saw in the workpiece, center
the saw blade in the kerf and check that saw teeth
are not engaged into the material.
If saw blade is binding, it may walk up or KICKBACK
from the workpiece as the saw is restarted.
13. 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 as shown in Fig. 1.
To minimize the risk of blade pinching and
kickback. When cutting operation requires the
resting of the saw on the work piece, the saw shall
be rested on the larger portion and the smaller
piece cut off.
14. Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and KICKBACK.
15. Blade depth and bevel adjusting locking levers
must be tight and secure before making cut.
If blade adjustment shifts while cutting, it may
cause binding and KICKBACK.
To avoid kickback, do support board
or panel near the cut.
Fig. 1
Don't support board or panel away
from the cut.
Fig. 2

16. 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.
NEVER place your hand or fingers behind the saw.
If kickback occurs, the saw could easily jump
backwards over your hand, possibly causing
severe injury.
17. 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 depths
of cut.
18. 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
damaged parts, gummy deposits, or a build-up of
debris.
19. 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.
20. 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.
21. Adjustments. Before cutting be sure depth and
bevel adjustments are tight.
22. Avoid cutting nails. Inspect for and remove all nails
from work piece before cutting.
23. When operating the saw, keep the cord away from
the cutting area and position it so that it will not
be caught on the workpiece during the cutting
operation.
Operate with proper hand support, proper
workpiece support, and supply cord routing away
from the work area.
WARNING: It is important to support the work
piece properly and to hold the saw firmly to prevent
loss of control which could cause personal injury.
Fig. 4 illustrates typical hand support of the saw.
24. Place the wider portion of the saw base on that
part of the work piece which is solidly supported,
not on the section that will fall off when the cut is
made.
As examples, Fig. 5 illustrates the RIGHT way to
cut off the end of board, and Fig. 6 the WRONG
way. If the work piece is short or small, clamp it
down.
DON’T TRY TO HOLD SHORT PLACES BY HAND!

25. Never attempt to saw with the circular saw held
upside down in a vise.
This is extremely dangerous and can lead to
serious accidents. (Fig. 7)
26. Before setting the tool down after completing a
cut, be sure that the lower (telescoping) guard has
closed and the blade has come to a complete stop.
27. Never touch moving parts.
Never place your hands, fingers or other body parts
near the tool’s moving parts.
28. Never operate without all guards in place.

of the tool.
29. Use right tool.
Don’t force small tool or attachment to do the job
of a heavy-duty tool.
Don’t use tool for purpose not intended —for
example— don’t use circular saw for cutting tree
limbs or logs.
30. Never use a power tool for applications other than
those specified.
Never use a power tool for applications other than
those specified in the Instruction Manual.
31. Handle tool correctly.

provided herein. Do not drop or throw the tool.
Never allow the tool to be operated by children,
individuals unfamiliar with its operation or
unauthorized personnel.
32. Keep motor air vent clean.
The tool’s motor air vent must be kept clean so
that air can freely flow at all times. Check for dust
build-up frequently.
33. Operate power tools at the rated voltage.
Operate the power tool at voltages specified on
their nameplates.
If using the power tool at a higher voltage than the
rated voltage, it will result in abnormally fast motor
revolution and may damage the unit and burn out
the motor.
Fig. 7
34. Do not run the saw while carrying it at your side.
35. Keep all screws, bolts and covers tightly in place.
Keep all screws, bolts, and plates tightly mounted.
Check their condition periodically.
36. Do not use power tools if the plastic housing or

CUTTING PROCEDURES
WARNING:
● Never touch the moving parts.
● Should the saw blade be stopped or make an abnormal noise during operation, turn
off the switch immediately.
● Don't remove circular saw from work piece during a cut while the saw blade is moving.
● Wear eye protection.
● Avoid cutting any material like metal, etc., that give off sparks.
● Do not use any abrasive wheels.
CAUTION:
● Always take care in preventing the power cord from coming near the revolving saw
blade.
● Before starting to saw, ensure that the saw blade has reached full speed revolution.
1. Place the saw body (base) on the work piece,
and as in Fig. 15 align the intended line of cut
with the saw blade, using the notch at the front
of the base. This relationship of base to work
pieces should remain unchanged regardless of
the inclination of the base.

MAINTENANCE AND INSPECTION
WARNING: To avoid serious accident, ensure the switch is in the OFF position and
disconnect the plug from the receptacle during maintenance and
inspection.
1. Inspecting the saw blade:
Since use of a dull saw blade will degrade efficiency and cause possible motor
malfunction, sharpen or replace the saw blade as soon as abrasion is noted.
CAUTION:
If a dull saw blade is used, reactive force is increased during cutting operation. Avoid
the use of the dull saw blade without repair.
2. Check the screws
Loose screws are dangerous. Regularly inspect them and make sure they are tight.
CAUTION: Using this power tool with loosened screws is extremely dangerous.
3. Inspecting the carbon brushes (Fig. 20)
The motor employs carbon brushes which are
consumable parts. Replace the carbon brush
with a new one when it becomes worn to its
wear limit. Always keep carbon brushes clean
and ensure that they slide freely within the
brush holders.
CAUTION:
Using this circular saw with a carbon brush which is worn in excess of the wear limit will
damage the motor.
NOTE: Use HITACHI carbon brush No. 38 indicated in Fig. 20.
4. Replacing carbon brushes:

screwdriver. The carbon brushes can then be
easily removed. (Fig. 21)
5. Performance checkup and maintenance of
safety cover
Keep the safety cover in good shape for smooth
performance at all times. Be sure to make
prompt repair in case of any malfunction.
6. Adjusting the base and saw blade to
maintain perpendicularity
