GENERAL SAFETY RULES

WARNING!

Read all instructions

Failure to follow all instructions listed below may result in

electric shock, ﬁ re and/or serious injury.

The term “power tool” in all of the warnings listed below

refers to your mains operated (corded) power tool or battery

operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

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.

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.

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

tools’ 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) Ensure the switch is in the oﬀ position before

inserting battery pack.

Inserting the battery pack into power tools that have

the switch on invites accidents.

b) 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.

c)

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.

English

7

d) 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.

e) 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.

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.

SHRUB SHEAR SAFETY WARNINGS

Temperatures at which the

battery can be recharged

BCL1015 0°C – 50°C

3) Regarding recharging time

Depending on the combination of the charger and

batteries, the charging time will become as shown in

Table 3

Table 3 Charging time (At 20°C)

Charger

Battery

UC10SFL

BCL1015 Approx. 40 min.

NOTE

The charging time may vary according to temperature

and power source voltage.

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 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.

English

11

○ When the pilot lamp ﬂ ikers (at 0.2-second 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 UC10SFL

is 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.

FUNCTIONAL DESCRIPTION

new blade when it loses sharpness.

Follow the steps below to replace the blade.

The tool shown in the illustration is the shrub shear, and it is

used in examples to explain features it shares with the grass

shear.

Before replacement, turn the switch on and oﬀ until the teeth

in the upper blade are positioned over the openings between

the teeth in the lower blade.

At this time, be careful of the moving blade.

WARNING

Be sure to turn oﬀ the power switch and remove the

battery from

the tool to prevent accidents.

CAUTION

Before blade replacement, be sure to use gloves and

attach the blade case or blade cover to prevent the blade

from coming into direct contact with your hands or face.

1. Remove the blade (Fig. 13)

(1) Turn the tool over, remove the four screws using

a Phillips

screwdriver, remove the bottom plate and the blade (with

blade case).

(2) Remove the remaining crank holder and crank cam (A)

from the tool. The grease used may cause the crank

holder and crank cam (A) to stick to the blade.

(3) Remove any chips and other debris from

inside the

housing.

2. Getting a new blade ready

Taking care to prevent injury from contact with the blade,

adjust the crank cam position as shown in Fig. 14.

This places the teeth in the upper blade over the openings

in the teeth in the lower blade.

3. Attach

the crank cam and crank cam holder to the

blade (Fig. 15)

The same type of crank cam holder is used in the shrub

shear and the grass shear. Use the crank holder installed

in the product.

4. Attach the new blade

(1) Align the pin on the tool with the

center hole in the crank

holder. (Fig. 16)

(2) When the hexagonal part in the crank holder and the

grooves in the gear do not align, ﬁ ne adjust so that the

crank holder aligns with the gear grooves. (Fig. 17)

(3) Turn over the tool making sure that the blade

does not

fall out, attach the bottom plate and secure it with the 4

screws. (Fig. 18)

NOTE

Be sure to check blade operation after it has been

attached. The blade and the crank cam has not been

properly ﬁ tted if the blade does not operate correctly. Do

the instructions

over from the beginning.

HOW TO USE

WARNING

○ To prevent accidents, make sure there are no people in

the work area.

○ Keep your hands and all parts of the body away from the

blade to prevent contact that could lead to injury.

○ Use protective goggles during work to prevent injury from

twigs and wood chips.

○ Do not use to tool to cut wire, metal plates or other hard

objects. The tool could be damaged and cause injury.

1. Trimming hedges and garden trees [Shrab shear]

CAUTION

○ Use a pair of pruning shears to cut thick branches before

using the shrub shear.

Do not force the

tool to prevent it from breaking.

○ Stop the tool immediately if the blade stalls against a too

heavy branch. Do not allow the motor to seize up as it

could damage the motor.

○ Use a sturdy ladder or step ladder when cutting tall

garden trees.

○ Use only

for cutting shrub.

(1) Clear the area around the garden tree you want to prune

and set up a stable platform to work from.

(2) Place the blade in the blade case to prevent accidental

contact.

(3) Install the battery in the tool.

(4) Press the Lock Oﬀ button and pull

back the switch to start

trimming.

NOTE

○ Lubricate (using sewing machine oil, mineral oil, etc.)

the blade before starting and then every hour. Use an

adequate amount of oil and wipe away excess oil.

○ During work (for example, when taking rests) do not

leave the tool in a place

exposed to direct sunlight or high

temperature. This will prevent proper cooling and could

result in damage.

○ Do not use the tool for work that exceeds its capacity.

Such operation could cause the motor to lock up or slow

down and will damage it.

Trimming garden trees

○ Use a

pair of pruning shears to remove 10 cm of branches

that are 8 mm or thicker so that they do not interfere with

trimming. (Fig. 20)

Fig. 20

○ Trees with luxuriant foliage should be trimmed starting

from the bottom and work up to achieve the desired

shape. (Fig. 21)

Fig. 21

Trimming hedges

○ Trim the top of hedges by moving the tool from right to left

(or left to right) and trim the sides by starting from below

and working up. (Fig. 22)

Fig. 22

NOTE

○ Do not use the tool for cutting the lawn or weeds. Grass

or weeds could stick to the blade.

○ Cut thick branches by gently pressing the blades against

the branch.

2. Trimming lawns [Grass shear]

CAUTION

○ Use only for cutting grass.

○ Stop the tool immediately should gravel

or branches

enter the blade during trimming and remove the battery.

Do not allow the motor to seize up as it could damage the

motor. Use a pair of tongs to gently remove gravel from

the blade. To prevent injury, keep hands, ﬁ ngers and

other body parts away from the

blade.

(1) Remove gravel and branches from the lawn to be

trimmed.

(2) Place the blade in the blade cover to prevent accidental

contact.

(3) Install the adjuster when required to adjust trimming

height.

(4) Install the battery in the tool.

(5) Press the Lock Oﬀ button and pull the

switch to start

trimming.

Place the tool on the lawn and slide the tool forward.

(Fig. 23)

○ During work (for example, when taking rests) do not

leave the tool in a place exposed to direct sunlight or high

temperature. This will prevent proper cooling and could

result in damage.

○ Do not use the tool for work that exceeds its capacity.

Such operation could cause the motor

to lock up or slow

down and will damage it.

○ Do not lower the front end of the blade to prevent sand,

gravel or soil from entering the blade and damaging it by

making it less sharp.

Trimming tall grass

Attempting to cut tall grass at one go will

expose the

blade to excessive load and wear the blade. First remove

1/3 of the height starting from the top before trimming it to

the desired height.

Trimming around stone walls and curbs

When trimming around curbs, move the blade sideways

along the curb. (Fig. 24)

This makes it possible

to trim without leaving untrimmed

edges.

3. Continuous operating time

Approx. 30 minutes (depending on the work conditions)

MAINTENANCE AND INSPECTION

WARNING

○ Be sure to turn the tool oﬀ and remove the battery

from the tool before making inspections or carrying out

maintenance.

○ Do not disassemble to blade. Failure to heed this warning

may result in injury.

○ Use gloves, or cloth to protect your hands when handling

the blade.

Failure to heed this warning may result in

injury.

1. Sharpening the blade (Fig. 19)

Move an iron ﬁ le in the direction of the arrow for a rough

sharpening then use an oil stone to give the blade a good

ﬁ nish.

(1) Use a ﬁ ne iron ﬁ le or one of

intermediate coarseness.

(2) Coat the oil stone with machine oil (bicycle oil or the like).

(3) Use a whetstone to gently remove any burrs from the

back of the blade edge.

When to sharpen the blade

While this will vary the type of trees that are trimmed and

how often

it is used, it is a good idea to sharpen the blade

about once a year to maintain a sharp edge.

NOTE

Do not use water for cleaning the blade to prevent rust or

other damage.

2. Lubricating the blade

During trimming, sap adhering to the blade edge will

increase load and

wear down the battery more rapidly.

Use machine oil (or bicycle oil or the like) to lubricate the

blade and wipe the blade with a cloth. To prevent the

blade from rusting, be sure to lubricate the blade after

use and when it will not be used for an extended

period

of time before placing it in the blade case.

3. 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.

4. Maintenance of the motor

The

motor unit winding is the very “heart” of the power

tool.

Exercise due care to ensure the winding does not

become damaged and/or wet with oil or water.

5. 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.

6. Storage

Store the power tool in a place in which the temperature

is less than 40°C and out of reach of children.

TROUBLESHOOTING

Use the inspections in the table below if the tool does not

operate normally. If this does not remedy the problem,

consult your dealer or the Hitachi Authorized Service Center.

Symptom Possible cause Remedy

Charger The Charge lamp does

not go on.

The power plug is not connected to an

AC outlet.

Connect the power plug to an AC outlet.

The battery is not properly connected to

the charger.

Insert the battery so that it is properly

seated in the charger.

The battery or charger electrodes are

soiled.

Use a cotton swab or other tool to clean

the electrodes.

The battery is extremely hot. Allow the battery to properly cool before

charging.

The Charge lamp does

not go oﬀ after 4 hours

of charging.

The battery or charger is faulty. Disconnect the power plug and consult

your dealer or the Hitachi

Authorized

Service Center.

Tool Does not operate. The battery is depleted. (The battery level

warning lamp does not go on.)

When a storage battery with little power

left is not used for an extended period of

time, battery power may drop so low that

it cannot turn on the battery level warning

lamp.

Charge the battery.

The battery has not been properly

installed.

Remove the storage battery from the

battery compartment in the tool and

check for foreign matter. Also check the

battery electrodes for soiling. Make sure

that the battery is pressed in until it clicks

into place.

The blade has been incorrectly

installed. If the blade does not move but the motor

is turning, the blade has probably been

incorrectly installed. Make sure that the

crank holder and crank cam has been

installed.

Foreign matter is lodged in the blade. When there is foreign matter in the

blade, remove the battery and

use a

pair of tongs or similar tool to remove it.

Take great care since the tool may start

operating when the foreign matter has

been removed.

Sap or rust may also prevent the blade

from operating. Use a wire brush or

similar tool to remove sap or rust.

The tool

has been used for heavy work. This is the eﬀ ect of a function that

protects the battery by turning oﬀ the

motor when the tool is exposed to an

excessive load. Release the switch and

remove what caused the excessive load

and pull back the switch to resume work.

The Lock Oﬀ button was not pressed

when the switch was pulled back.

To prevent accidents from incorrect

operation, the Lock Oﬀ switch must be

pressed while the switch is pulled back to

start the motor.

The tool does not trim

well.

The blade has become dull. Use a wire brush

or other tool to remove

sap and rust and use a ﬁ le or whetstone

to sharpen the blade. If these eﬀ orts fail

to make the blade sharper, the blade

has reached the end of its service life.

Replace the blade with a new one.

English

15

Symptom Possible cause Remedy

Toolr The tool does not trim

well.

[Shrub shear]

The blade stopped because it was used

to cut a branch whose width exceeded

the blade’s cutting capacity.

NOTE

Work that will repeatedly cause the

blade to stop will eventually damage

the motor.

Some garden trees have wood that

is very hard and

may be beyond the

capacity of the tool even if it is of a width

that is within normal capacity. Use a

pair of pruning shear to remove thick

branches before starting work.

An oblique cut may also exceed the

capacity of the tool since the length of

the cut

increases. Be sure to trim thick

branches at right angles.

Important notice on the batteries for the Hitachi

cordless power tools

Please always use one of our designated genuine

batteries. We cannot guarantee the safety and

performance of our cordless power tool when used with

batteries other than these designated by us, or when

the battery is disassembled and modiﬁ ed

(such as

disassembly and replacement of cells or other internal

parts).

NOTE

Due to HITACHI’s continuing program of research and

development, the speciﬁ cations herein are subject to

change without prior notice.
