SAFETY

GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions 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.

3

English

A moment of inattention while operating power

tools may result in serious personal injury.

b) Use personal protective equipment. Always

wear eye protection.

Protective equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protection used

for appropriate conditions will reduce personal

injuries.

c) Prevent unintentional starting. Ensure the

switch is in the oﬀ -position before connecting

to power source and/or battery pack, picking

up or carrying the tool.

Carrying power tools with your ﬁ nger on the switch

or energising 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 dust collection 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 aﬀ ect the

power tool’s 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,

taking into account the working conditions and

the work to be performed.

Use of the power tool for operations diﬀ erent

from those intended could result in a hazardous

situation.

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 burns.

6) Service

a) Have your power tool serviced by a

qualiﬁ ed 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.

English

WARNING:

Some dust created by power sanding, sawing,

grinding, drilling, and other construction activities

contains chemicals known to the State of California

to cause cancer, birth defects or other reproductive

harm. Some examples of these chemicals are:

●

Lead from lead-based paints,

●

Crystalline silica from bricks and cement and other

masonry products, and

●

Arsenic and chromium from chemically-treated

lumber.

Your risk from these exposures varies, depending on

how often you do this type of work. To reduce your

exposure to these chemicals: work in a well ventilated

area, and work with approved safety equipment, such

as those dust masks that are specially designed to

ﬁ lter out microscopic particles.

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 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 the power tool by insulated gripping

surfaces only, when performing an operation

where the cutting tool may contact hidden wiring.

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 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.

Kickback causes and related warnings

– 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.

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 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.

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.

f) 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.

g) Use extra caution when sawing into existing

walls or other blind areas.

The protruding blade may cut objects that can cause

kickback.

English

6. Keep all screws, bolts and covers tightly in place.

Keep all screws, bolts, and plates tightly mounted.

Check their condition periodically.

7. Do not use power tools if the plastic housing or

handle is cracked.

Cracks in the tool’s housing or handle can lead to

electric shock. Such tools should not be used until

repaired.

8. Blades and accessories must be securely

mounted to the tool.

Prevent potential injuries to yourself or others. Blades,

cutting implements and accessories which have been

mounted to the tool should be secure and tight.

9. Carefully handle power tools.

Should a power tool be dropped or struck against

hard materials inadvertently, it may be deformed,

cracked, or damaged.

10. Do not wipe plastic parts with solvent.

Solvents such as gasoline, thinner benzine, carbon

tetrachloride, and alcohol may damage and crack

plastic parts. Do not wipe them with such solvents.

Wipe plastic parts with a soft cloth lightly dampened

with soapy water and dried thoroughly.

11. Keep motor air vent clean.

The tool’s motor air vent must be kept clean so that

air can freely ﬂ ow at all times. Check for dust build-up

frequently.

12. NEVER leave tool running unattended. Turn

power oﬀ .

Don’t leave tool until it comes to a complete stop.

13. NEVER touch the blade with bare hands after

operation.

14. For this mode, the saw blades should be 165 mm.

15. Because the cordless circular saw operates by

battery power, be aware of the fact that it can begin to

operate at any time.

16. When working at elevated locations, clear the area of

other people and aware of conditions below you.

17. Do not give a strong shock to the switch panel or

break it. It may lead to a trouble.

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

●

When the battery charger has been continuosly

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.

●

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 charge indicator

lamp of the charger lights for 0.3 seconds, does

not light for 0.3 seconds (oﬀ for 0.3 seconds). In

such a case, ﬁ rst let the battery cool, then start

charging.

●

When the charge indicator lamp ﬂ ickers (at

0.2–second intervals), check for and take out

any foreign objects in the charger’s battery

installation hole. If there are no foreign objects,

it is probable that the battery or charger is

malfunctioning. Take it to your authorized

Service Center.

PRIOR TO OPERATION

CAUTION

To avoid serious accident, ensure the switch is in

the OFF position, and pull out the battery.

1. Check the work area environment

Check the work area to make sure that it is clear of

debris and clutter.

Clear the area of unnecessary personnel. Ensure that

lighting and ventilation is adequate.

2. Mounting the Saw Blade (Fig. 8)

WARNING

If the left-hand bolt is worked using other tools

than the provided hex. wrench, excessive

tightening and insuﬃ cient tightening may take

place, resulting in injury.

(1) Thoroughly remove any sawdust which has

accumulated on the spindle, bolt and washers.

(2) Apply quality machine oil to the surfaces of washers

(B) and (A) which come into contact with the blade.

(3) As shown in Fig. 8, one side of the saw blade should

be ﬁ tted to the projecting center of washer (A) which

matches the blade’s inner diameter, and the other

side to the concave side of washer (B).

(4) To ensure that the saw blade rotates in the correct

direction, make sure the arrow on the saw blade

points in the same direction indicated by the arrow on

the saw cover.

(5) Using the ﬁ ngers, tighten the left-hand bolt securing

the saw blade as much as possible. Then press the

lock button, lock the spindle, and fully tighten the left-

hand bolt with the hex. wrench.

4. Check performance of lower guard

WARNING

Make absolutely sure that the lower guard is not

ﬁ xed. 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. 2) 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 lower guard

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.

5. Check for proper operation of the brake

This circular saw features an electric brake that

functions when the switch is released. Before using

the circular saw, ensure that the electric brake

functions properly. If it does not, bring the tool to a

HITACHI AUTHORIZED SERVICE CENTER.

6. Prepare a wooden work bench (Fig. 11)

Since the saw blade will extend beyond the lower

surface of the lumber, place the lumber on a work

bench when cutting. If a square block is utilized

as a work bench, select level ground to ensure it is

properly stabilized. An unstable work bench will result

in hazardous operation.

BaseLumber

Work bench

operation at an inclined precise angle, use the circular

saw after adjusting the angle between the base and

the saw blade with a protractor, etc.

3. Fine tuning of parallelism

It is possible to ﬁ ne-tune the parallelism of the saw

blade to the base using the parallelism adjustment

screw.

Adjustment has already been made at the time of

shipment from the factory. However, in the unlikely

event of parallelism being faulty, adjust as follows.

(1) Unfasten only the mounting screws of the saw cover

hinge portion (Fig. 16).

Fig. 16

17

English

(2) Retract the lower guard into the saw cover.

(3) Insert wood chip in the rear side of the saw blade

base, and mark the position on the base (Fig. 17).

Fig. 17

(4) Move the marked wood chip to the front of the base,

and turn the parallelism adjustment screw so that the

marking corresponds to the base side (Fig. 18).

Fig. 18

NOTE

After parallelism adjustment, if the saw cover hinge

portion is loose, tighten the M5 U-Nut. Do not over

tighten the nut as this may result in deformation of the

bevel plate.

(5) After adjustment, fasten the mounting screws tightly

in place.

NOTE

Parallelism may be slightly faulty if the cutting depth is

adjusted after parallelism adjustment.

4. Adjusting the guide piece

On the circular saw, it is possible to make ﬁ ne

adjustment of the ﬁ xing position of the guide piece,

where the saw blade and the premarked line are to be

aligned.

When the saw is shipped from the factory, the linear

portion of a front scale on the guide piece is aligned

with the central position of the saw blade (Fig. 19).

Guide piece

Fig. 19

Loosen the ﬁ xed M4 screw on the guide piece, should

the ﬁ xing position be wrong, and make necessary

adjustment of the position.
