SAFETY

GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS

WARNING:Read and understand all instructions.

Failure to follow all instructions listed below, may result in electric shock,

fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

1. Work Area

(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite

accidents.

(2) 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.

(3) Keep bystanders, children, and visitors away while operating a power tool.

Distractions can cause you to lose control.

2. Electrical Safety

(1) A battery operated tool with integral batteries or a separate battery pack must be

recharged only with the specified charger for the battery.

A charger that may be suitable for one type of battery may create a risk of fire when

used with another battery.

(2) Use battery operated tool only with specifically designed battery pack.

Use of any other batteries may create a risk of fire.

3. Personal Safety

(1) Stay alert, watch what you are doing and use common sense when operating a

power tool. Do not use tool while tired or under the influence of drugs, alcohol, or

medication. A moment of inattention while operating power tools may result in

serious personal injury.

(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your

hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long

hair can be caught in moving parts.

(3) Avoid accidental starting. Be sure switch is off position before inserting battery.

Carrying tools with your finger on the switch or inserting the battery pack into a tool

with the switch on invites accidents.

(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that

is left attached to a rotating part of the tool may result in personal injury.

(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and

balance enables better control of the tool in unexpected situations.

(6) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety

shoes, hard hat, or hearing protection must be used for appropriate conditions.

English

4. Tool Use and Care

(1) Use clamps or other practical way to secure and support the workpiece to a stable

platform. Holding the work by hand or against your body is unstable and may lead to

loss of control.

(2) Do not force tool. Use the correct tool for your application. The correct tool will do

the job better and safer at the rate for which it is designed.

(3) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled

with the switch is dangerous and must be repaired.

(4) Disconnect battery pack from tool or place the switch in the locked or off position

before making any adjustments, changing accessories, or storing the tools. Such

preventive safety measures reduce the risk of starting the tool accidentally.

(5) Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

(6) 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 sparks, burns, or a fire.

(7) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained

tools, with sharp cutting edges are less likely to bind and are easier to control.

(8) Check for misalignment or binding of moving parts, breakage of parts, and any other

condition that may affect the tools operation. If damaged, have the tool serviced

before using. Many accidents are caused by poorly maintained tools.

(9) Use only accessories that are recommended by the manufacturer for your model.

Accessories that may be suitable for one tool may create a risk of injury when used

on another tool.

5. Service

(1) Tool service must be performed only by qualified repair personnel. Service or

maintenance performed by unqualified personnel could result in a risk of injury.

(2) When servicing a tool, use only identical replacement parts. Follow instructions in

the Maintenance section of this manual. Use of unauthorized parts or failure to follow

Maintenance Instruction may create a risk of electric shock or injury.

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 filter

out microscopic particles.

English

SPECIFIC SAFETY RULES

1.DANGER! Keep hands away from cutting area and 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.

Keep your body positioned to either side of the saw blade, but not in line with the saw

blade. KICKBACK could cause the saw to jump backwards. (See KICKBACK)

Do not reach underneath the work. The guard can not protect you from the blade below

the work.

2. Check lower guard for proper closing before each use. Do not operate 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.

3. Check the operation and condition of the lower guard spring. If the guard 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 buildup of debris.

4.lower guard should be retracted manually only for special cuts such as “Pocket Cuts”

and “Compound Cuts.” Raise lower guard by Retracting Handle. As soon as blade enters

the material, lower guard must be released. For all other sawing, the lower guard should

operate automatically.

5.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.

6.NEVER hold piece being cut in your hands or across your leg. It is important to support

the work properly to minimize body exposure, blade binding, or loss of control.

7.Hold tool by insulated gripping surfaces 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 tool “live” and shock the operator.

8.When ripping always use a rip fence or straight edge guide. This improves the accuracy

of cut and reduces the chance for blade binding.

9.Always use blades with correct size and shape (diamond vs. round) arbor holes. Blades

that do not match the mounting hardware of the saw will run eccentrically, causing loss

of control.

10.Never use damaged or incorrect blade washers or bolts. The blade washers and bolt

were specially designed for your saw, for optimum performance and safety of operation.

11.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 tool misuse and/or incorrect operating procedures or conditions

and can be avoided by taking proper precautions as given below:

English

12. Maintain a firm grip on the saw and position your body and arm in a way that allows you

to resist KICKBACK forces. KICKBACK forces can be controlled by the operator, if proper

precautions are taken.

13. 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.

14. When restarting a saw in the workpiece, center the saw blade in the kerf and check that

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.

15.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.

To avoid kickback, do support board Don't support board or panel away

or panel near the cut. from the cut.

Fig. 1 Fig. 2

16.Do not use dull or damaged blade. Unsharpened or improperly set blades produce

narrow kerf causing excessive friction, blade binding, and KICKBACK.

17.Blade depth and bevel adjusting locking levers must be tight and secure before making

cut. If blade adjustment shifts while cutting, it will cause binding and KICKBACK.

18.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.

19.Hold tools 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

make exposed metal parts of the tool “live” and shock the operator.

20.Never touch moving parts.

Never place your hands, fingers or other body parts near the tool’s moving parts.

21.Never operate without all guards in place.

Never operate this tool without all guards or safety features in place and in proper

working order. If maintenance or servicing requires the removal of a guard or safety

feature, be sure to replace the guard or safety feature before resuming operation of the

tool.

English

22.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.

23.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.

24.Handle tool correctly.

Operate the tool according to the instructions 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.

25.Definitions for symbols.

---/min ........ revolutions or reciprocation per minute

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

Keep all screws, bolts, and plates tightly mounted. Check their condition periodically.

27.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.

28.Blades and accessories must be securely mounted to the tool.

Prevent potential injuries to yourself or others. Blades, cutting implements and accesso-

ries which have been mounted to the tool should be secure and tight.

29.Never use a tool which is defective or operating abnormally.

If the tool appears to be operating unusually, making strange noises, or otherwise

appears defective, stop using it immediately and arrange for repairs by a Hitachi

authorized service center.

30.Carefully handle power tools.

Should a power tool be dropped or struck against hard materials inadvertently, it may be

deformed, cracked, or damaged.

31.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.

English

IMPORTANT SAFETY INSTRUCTIONS FOR USE OF THE CORDLESS

CIRCULAR SAW

WARNING:Death or serious bodily injury could result from improper or unsafe use

of the cordless circular saw. To avoid these risks, follow these basic

safety instructions:

(2) Regarding the temperature of the rechargeable battery

The temperatures for rechargeable batteries are as shown in the table below, and

batteries that have become hot should be cooled for a while before being recharged.

4. Disconnect battery charger from the receptacle

CAUTION:

Do not pull the plug out of the receptacle by pulling on the cord.

Make sure to grasp the plug when removing from receptacle to avoid damaging cord.

5. Remove the battery from the battery charger

Supporting the battery charger by hand, pull out the battery from the battery charger.

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.

● If the battery is recharged when it is warm due to battery use or exposure to sunlight,

the pilot lamp may light in green.

The battery will not be recharged. In such a case, let the battery cool before charging.

● When the pilot lamp flickers rapidly in red (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 an

authorized Service Center.

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.

Table 3 Recharging of batteries that have become hot

Rechargeable battery Temperatures at which the battery can be recharged

EB1414S 23°F — 140°F (–5°C — 60°C)

English

(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.

aged. Have it repaired immediately.

2. Insert the battery to the battery charger.

Insert the battery into the battery charger as shown in Fig. 7. Make sure it contacts the

bottom of the battery charger.

3. Charging.

When the battery is connected to the battery charger, charging starts, and the charge time

lamp lights red, orange, or green according to the remaining charging time. (See

Table 4)

(1) Lamp indications

This charger is equipped with a charge time lamp that indicates remaining charging time,

and a charge status lamp that indicates battery status as shown in Table 4.

(a) Charging time

After charging commences, the charge time lamp lights red indicating 30 minutes,

orange indicating 20 minutes, and green indicating 5 minutes until completion. When

the battery is fully charged, the charge status lamp lights green, and the buzzer sounds

continuously for 6 seconds.

(b) Overheat standby

When the battery is overheated, it cannot be charged, and the charge time lamp

flashes red (in 0.6 second intervals). Leave the battery inserted in the charger, and

charging will commence when the battery cools down.

When there is a malfunction with the battery or charger, the charge status lamp

flashes orange rapidly (in 0.2 second intervals), and the buzzer sounds intermittently

for 5 seconds.

5. Remove the battery from the battery charger.

Supporting the battery charger with hand, pull out the battery from the battery charger.

CAUTION:

● Repair is required if the receptacle is not secured properly or the power cord does not

stay in the receptacle. Consult your electrician. Using the charger in this condition

may lead to fire.

● If the charge status lamp is blinking orange rapidly (in 0.2 second intervals) and the

buzzer sounds intermittently for 5 seconds, check that the hole for connecting the

battery is not obstructed. Remove any obstructions. If no obstructions are found, the

battery or charger may be malfunctioned. Return both to your place of purchase.

● If the charge time lamp does not light when the power cord is connected to the

receptacle, disconnect the power cord, and check that the battery is attached

correctly.

Rechargeable battery Temperatures at which the battery can be recharged

EB1414S 23°F — 131°F (–5°C — 55°C)

English

● The battery retains heat when used or left for prolonged periods in direct sunlight.

In this state, the charge time lamp flashes red, and the battery cannot be charged

immediately. Leave the battery inserted in the charger, and charging will commence

when the battery cools down.

● If the lamp goes out while charging, disconnect the power cord, and leave for 3 to 5

minutes before reconnecting. If the problem persists, call for repairs.

● Leave 5 minutes between charging batteries as the charger may overheat leading to

malfunction.

● The battery life is finished if it can only be used for short periods even when fully

charged. Purchase a new battery. Continuing to use a depleted battery may cause the

charger to malfunction.

NOTE:

䡬 Charging times may be longer depending on the surrounding temperature and battery

conditions.

䡬 Charge time lamp indications are only a guide, and may vary depending on the

surrounding temperature and battery conditions.

䡬 Remove the battery from the charger when not in use.

Revitalizing the battery (trickle recharge)

A new battery or a battery that has not been used for extensive periods may not charge

completely due to internal chemicals being inert.

Leave the battery inserted in the charger for 8 to 12 hours after charging is complete. The

charger automatically “revitalizes” the battery by trickle recharging.

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.
