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 mainsoperated (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.

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 toolʼs 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.

Page 6

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.

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.

HEDGE TRIMMER SAFETY WARNINGS

○ Keep all parts of the body away from the cutter

blade. Do not remove cut material or hold material to be cut when blades are moving. Make sure the switch is oﬀ when clearing jammed material. A

moment of inattention while operating the hedge trimmer may result in serious personal injury.

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. 10)

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. 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.

6. Cleaning on the outside

When the hedge trimmer 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.

7. Transport of the tool

Remove the battery and attach the blade case to the

blade before carrying this tool.

If you carry it without the blade case, the blade may

come in contact with your body, causing injury.

8. Storage

Store the hedge trimmer 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.

Page 12

CAUTION

In the operation and maintenance of power tools, the

safety regulations and standards prescribed in each country must be observed.

Important notice on the batteries for the Hitachi cordless power tools
