GENERAL POWER TOOL SAFETY
WARNINGS
WARNING
Read all safety warnings, instructions, illustrations and
specifications provided with this power tool.
Failure to follow all instructions listed below 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

PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.
CORDLESS CIRCULAR SAW SAFETY
WARNINGS
Cutting procedures
a) 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.
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 the workpiece in your hands or across
your leg while cutting. 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 the 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 could give the operator
an electric shock.
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.
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 off-centre, 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.
Kickback causes and related warnings
-kickback is a sudden reaction to a pinched, jammed 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 jammed 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.
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 so that the saw teeth are not
engaged into the material.
If a saw blade binds, it may walk up or kickback from the
workpiece as the saw is restarted.
d) Support large panels to minimise 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.
00BookC1806DAAUST.indb800BookC1806DAAUST.indb8 2021/05/1210:23:542021/05/1210:23:54

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 the cut.
If blade adjustment shifts while cutting, it may cause
binding and kickback.
g) Use extra caution when sawing into existing walls
or other blind areas.
The protruding blade may cut objects that can cause
kickback.
Lower guard function
a) Check the lower guard for proper closing before
each use. Do not operate the saw if the lower guard
does not move freely and close instantly. Never
clamp or tie the lower guard into the open position.
If the saw is accidentally dropped, the 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.
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 damaged
parts, gummy deposits, or a build-up of debris.
c) The lower guard may be retracted manually only for
special cuts such as “plunge cuts” and “compound
cuts”. Raise the lower guard by the retracting
handle and as soon as the 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 the 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.
ADDITIONAL SAFETY WARNINGS
1. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
2. Never disassemble the rechargeable battery and
charger.
3. Never short-circuit the rechargeable battery.
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
4. Do not dispose of the battery in fire. If the battery is burnt,
it may explode.
5. When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch. Please leave
it without using it for approximately 15 minutes.
6. Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
7. Using an exhausted battery will damage the charger.
8. Bring the battery to the shop from which it was purchased
as soon as the post-charging battery life becomes too
short for practical use. Do not dispose of the exhausted
battery.
9. Wear earplugs to protect your ears during operation.
10. Use only blade diameter specified on the machine.
11. Do not use any abrasive wheel.
12. Do not use saw blades which are deformed or cracked.
13. Do not use saw blades made of high speed steel.
14. Do not use saw blades which do not comply with the
characteristics specified in these instructions.
15. Do not stop the saw blades by lateral pressure on the
disc.
16. Always keep the saw blades sharp.
17. Ensure that the lower guard moves smoothly and freely.
18. Never use the circular saw with its lower guard fixed in
the open position.
19. Ensure that the retraction mechanism of the guard
system operates correctly.
20. Never operate the circular saw with the saw blade turned
upward or to the side.
21. Ensure that the material is free of foreign matters such as
nails.
22. The saw blades range should be from 165 mm to
162 mm.
23. Pull out battery before carrying out any adjustment,
servicing or maintenance.
24. Be careful of brake kickback.
This circular saw features an electric brake that functions
when the switch is released. As there is some kickback
when the brake functions, be sure to hold the main body
securely.
25. Ensure that the switch is in the OFF position. If the battery
installed to power tool while the switch is in the ON
position, the power tool will start operating immediately,
which could cause a serious accident.
26. Avoid cutting in the state where the base has floated up
from the material.
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.
27. Support large panels to minimize the risk of blade
pinching and KICKBACK. Large panels tend to sag
under their own weight (Fig. 3). 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. 2.
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.
28. Use extra caution when making a “Pocket 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
(Fig. 4). If kickback occurs, the saw could easily jump
backwards over your hand, possibly causing severe
injury.
29. 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. 5
illustrates typical hand support of the saw.
30. 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 offwhen the cut is made. As
examples, Fig. 6 illustrates the RIGHT way to cut offthe
end of board, and Fig. 7 the WRONG way. If the work
piece is short or small, clamp is down.
DON’T TRY TO HOLD SHORT PLACES BY HAND!
31. 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. 8).
32. When using the guide, do not attempt an inclined cut
which would allow the cut material to slip between the
saw blade and guide. Doing so could result in injury.
(Fig. 12)

NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
CAUTION
When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
4. Disconnect the charger’s power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period
is not activated, the electric discharge might be low when
using them the first and second time. This is a temporary
phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2–3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery. If
you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate, and
the battery life will be shortened. Leave the battery and
recharge it after it has cooled for a while.
CAUTION
○If the battery is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used,
the pilot lamp of the charger lights up green or lights
for 1 second, does not light for 0.5 seconds (offfor
0.5 seconds). In such a case, first let the battery cool,
then start charging.
○When the pilot lamp flickers in red (at 0.2-seconds
intervals), check for and take out any foreign objects in
the charger’s battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.
○Since the built-in micro computer takes about 3 seconds
to confirm that the battery being charged with chargers
are taken out, wait for a minimum of 3 seconds before
reinserting it to continue charging. If the battery is
reinserted within 3 seconds, the battery may not be
properly charged.

MAINTENANCE AND INSPECTION
1. Inspecting the saw blade
Since use of as dull saw blade will degrade efficiency
and cause possible motor malfunction, sharpen or
replace the saw blade as soon as 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
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Inspecting the carbon brushes (Fig. 22)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon brush
No. ⓐshown in the figure when it becomes worn to or
near the “wear limit” ⓑ. In addition, always keep carbon
brushes clean and ensue that they slide freely within the
brush holders.
CAUTION
When replacing the new carbon brushes, always use
genuine HiKOKI carbon brushes with the number
specified in the drawing.
4. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. Motor unit maintenance
The motor winding is an important part of this tool. Avoid
damaging and be careful to avoid contact with cleaning
oil or water.
After 50 hours of use, clean the motor by blowing into the
ventilation holes of the motor housing with dry air from an
air gun or other tool (Fig. 25).
Dust or particle accumulation in the motor can result in
damage.

6. Inspecting and maintaining the lower guard
Always make sure that the lower guard moves smoothly.
In the event of any malfunction, immediately repair the
lower guard.
For cleaning and maintenance, use an air gun or other
tool to blow clean the space between the lower guard
and gear cover as well as the rotation part of the lower
guard with dry air (Fig. 25).
Doing so is effective for the emission of chips or other
particles.
Accumulation of chips or other particles around the lower
guard may result in malfunction or damage.
WARNING
To prevent dust inhalation or eye irritation, wear
protective safety goggles and a dust mask when
using an air gun or other tool to clean the lower guard,
ventilation holes or other parts of the product.
Ensure smooth movement

8. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
9. Cleaning on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
10. Storage
Storing in a place below 40°C and out of the reach of
children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
significantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, significantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to five times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
