GENERAL POWER TOOL SAFETY

WARNINGS

WARNING

Read all safety warnings, instructions, illustrations and

speciﬁ cations provided with this power tool.

Failure to follow all instructions listed below may result in

electric shock, ﬁ re 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

ﬂ ammable liquids, gases or dust.

Power tools create sparks which may ignite the dust

or 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.

Unmodiﬁ ed 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.

f) If operating a power tool in a damp location

is unavoidable, use a residual current device

(RCD) protected supply.

Use of an RCD 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 inﬂ uence of drugs, alcohol or

medication.

safety shoes, hard hat or hearing protection used for

appropriate conditions will reduce personal injuries.

8

English

5) Battery tool use and care

a) Recharge only with the charger speciﬁ ed by the

manufacturer.

A charger that is suitable for one type of battery pack

may create a risk of ﬁ re when used with another

battery pack.

b) Use power tools only with speciﬁ cally

designated battery packs.

Use of any other battery packs may create a risk of

injury and ﬁ re.

c) When battery pack is not in use, keep it away

from other metal objects, like paper clips, coins,

keys, nails, screws or other small metal objects,

that can make a connection from one terminal to

another.

Shorting the battery terminals together may cause

burns or a ﬁ re.

d) Under abusive conditions, liquid may be ejected

from the battery; avoid contact. If contact

accidentally occurs, ﬂ ush with water. If liquid

contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation or

by the manufacturer or authorized service providers.

PRECAUTION

Keep children and inﬁ rm persons away.

When not in use, tools should be stored out of reach of

children and inﬁ rm 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 ﬁ rm 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.

e) Do not use dull or damaged blades.

Unsharpened or improperly set blades produce narrow

kerf causing excessive friction, blade binding and

kickback.

9

English

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

ﬂ oor.

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 ﬁ re. 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 inﬂ ammables 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 speciﬁ ed 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 speciﬁ ed 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 ﬁ xed 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 should be 190 mm external diameter.

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 ﬂ oated 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 ﬁ ngers 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 ﬁ rmly 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 oﬀ when the cut is made. As

examples, Fig. 6 illustrates the RIGHT way to cut oﬀ the

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. 9)

33. Should lever remain loosened, it will create a very

hazardous situation. Always thoroughly clamp it.

(Fig. 11)

34. It is very hazardous to allow lever to remain loosened.

Always thoroughly clamp it. (Fig. 12)

10

English

35. Prior to cutting operation, make sure the material you

are going to cut. If the material to be cut is expected to

generate harmful / toxic dusts, make sure the dust bag

or appropriate dust extraction system is connected with

dust outlet tightly.

Wear the dust mask additionally, if available.

○ Before starting to saw, conﬁ rm that the saw blade

has attained full-speed revolution.

○ Should the saw blade stop or make an abnormal

noise while operating, promptly turn OFF the switch.

○ Using the circular saw with the saw blade facing

upwards or sideways is very hazardous. Such

uncommon applications should be avoided.

○ When cutting materials, always wear protective

glasses.

○ When ﬁ nished with a job, pull out the battery.

36. After having attached the saw blade, reconﬁ rm that the

lock lever is ﬁ rmly secured in the prescribed position.

37. Do not expose directly your eye to the light by looking

into the light.

If your eye is continuously exposed to the light, your eye

will be hurt.

38. Do not use the product if the tool or the battery terminals

(battery mount) are deformed.

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 ﬁ rmly 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 ﬁ rst 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 (oﬀ for

0.5 seconds). In such a case, ﬁ rst let the battery cool,

then start charging.

(*1) About the mode select function

Each time the mode selector switch is pushed, the

operation mode changes.

When Silent mode is selected, the Silent mode indicator

lamp lights up.

Silent mode reduces maximum motor RPM enabling

eﬃ cient work with less noise.

If the load increases while the motor is operating in

Silent mode, it automatically changes to Power mode.

Additionally, if the load decreases again, it automatically

returns to Silent mode.

In Power mode, no change is made to Silent mode even

when the load decreases.

Mode No-load speed

Power 3800 /min

Silent 2000 /min

NOTE

○ The mode will only change after a battery is installed and

the switch is pulled once.

○ The current mode will be maintained even if the switch is

on/oﬀ , or the battery is removed/reinserted.

LED LIGHT WARNING SIGNALS

(Fig. 25)

This product features functions that are designed to protect

the tool itself as well as the battery. While the switch is

pulled, if any of the safeguard functions are triggered

during operation, the LED light will blink as described in

Table 3. When any of the safeguard functions are triggered,

immediately remove your ﬁ nger from the switch and follow

the instructions described under corrective action.

Fig. 25

○ When the pilot lamp ﬂ ickers 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 conﬁ rm 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 eﬃ ciency

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. 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. 26).

Dust or particle accumulation in the motor can result in

damage.

4. 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. 26).

Doing so is eﬀ ective 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.

6. 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.

7. 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.

8. Storage

Store the power tool and battery in a place in which

the temperature is less than 40°C and out of 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,

signiﬁ cantly reducing battery usage time or rendering

the batteries incapable of holding a charge.

However, signiﬁ cantly reduced battery usage time may

be recovered by repeatedly charging and using the

batteries two to ﬁ ve 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.
