WARNINGS
Read all safety warnings, instructions, illustrations and specifications 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.

Work area safety

• Keep work area clean and well lit.
• Cluttered or dark areas invite accidents.
• 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 or fumes.
• Keep children and bystanders away while operating a power tool.
• Distractions can cause you to lose control.

Electrical safety

• 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.
• 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.
• Do not expose power tools to rain or wet conditions.
• Water entering a power tool will increase the risk of electric shock.
• 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.
• 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.
• 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.

Personal safety

• 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 influence of drugs, alcohol or medication.
• A moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection.
• Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
• 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.
• 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.
• Do not overreach. Keep proper footing and balance at all times.
• This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts.
• Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used.

PRECAUTION
Keep children and in firm persons away. When not in use, tools should be stored out of reach of children and infi rm persons.

DEMOLITION HAMMER SAFETY
WARNINGS
Safety instructions for all operations

1. Wear ear protectors. Exposure to noise can cause hearing loss.
2. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
3. Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord.
4. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

ADDITIONAL SAFETY WARNINGS

1. Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.
2. Ensure that the power switch is in the OFF position.
3. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.
4. When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.
5. RCD The use of a residual current device with a rated residual current of 30mA or less at all times is recommended.
6. Do not touch the bit during or immediately after operation. The bit becomes very hot during operation and could cause serious burns.
7. Before starting to break, chip or drill into a wall, floor or ceiling, thoroughly confirm that such items as electric cables or conduits are not buried inside.
8. Wear a mask when turning your head upward.
9. Properly set the bit holder.
10. At the start of work, confirm screw tightening.
11. When working at a highly elevated location, pay attention to articles and persons below.

• Operate this Demolition Hammer by utilizing its empty weight. The performance will not be better even if it is pressed or thrust forcibly against the work surface.
• Hold this Demolition Hammer with a force just sufficient to counteract the reaction.
• This Demolition Hammer is equipped with a spring cushion on the handle so that chipping vibration is not conveyed to the operator.
• Operate this Demolition Hammer without forcing the handle too strongly.

CAUTION
Sometimes the power tool does not begin the striking stroke even when the motor rotates because the oil has become thick. If the power tool is used at low temperatures or if it is used after a long idle time, this Demolition Hammer should be kept running in for about five minutes in order to warm it up.

GREASE REPLACEMENT
This Demolition Hammer is of full air-tight construction to protect against dust and to prevent lubricant leakage. Therefore, this Demolition Hammer can be used without lubrication for long periods. Replace the grease as described below.

Grease Replacement Period
After purchase, replace grease after every 6 months of usage. Ask for grease replacement at the nearest authorized Service Center.

MAINTENANCE AND INSPECTION

CAUTION
Be sure to switch OFF and disconnect the attachment plug from the receptacle to avoid a serious accident.

Inspecting accessories
Since use of a dull accessory, such as a bull point, a cutter, etc. will degrade effi ciency and cause possible motor malfunction, sharpen or replace with a new one as soon as abrasion is noted.

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.

Inspecting the retainer
The retainer may become loose due to excessive use. Always, pay attention to its proper functioning to securely  hold the accessory shank portion. If any wear and tear is found, bring this Demolition Hammer to an authorized service center for maintenance service.

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.

Inspecting the carbon brushes (Fig. 7)
The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit” ⓐ, it results in motor trouble. When an auto- stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers ⓑ shown in the Fig. 7. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

Replacing supply cord
If the replacement of the supply cord is necessary, it has to be done by HiKOKI Authorized Service Center to avoid a safety hazard .

CAUTION
In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.

We guarantee HiKOKI Power Tools in accordance with statutory/country specifi c regulation. This guarantee does not cover defects or damage due to misuse, abuse, or normal wear and tear. In case of complaint, please send the Power Tool, undismantled, with the GUARANTEE CERTIFICATE found at the end of this Handling instruction, to a HiKOKI Authorized Service Center.

IMPORTANT
Correct connection of the plug The wires of the main lead are coloured in accordance with the following code:

• Blue: — Neutral
• Brown: — Live

As the colours of the wires in the main lead of this tool may not correspond with the coloured markings identifying the terminals in your plug proceed as follows: The wire coloured blue must be connected to the terminal marked with the letter N or coloured black. The wire coloured brown must be connected to the terminal marked with the letter L or coloured red. Neither core must be connected to the each terminal.

NOTE
This requirement is provided according to BRITISH STANDARD 2769: 1984. Therefore, the letter code and colour code may not be applicable to other markets except The United Kingdom. Information concerning airborne noise and vibration The measured values were determined according to EN62841 and declared in accordance with ISO 4871. Measured A-weighted sound power level: 102 dB(A) Measured A-weighted sound pressure leve: 82 dB(A) Uncertainty K: 3 dB(A). Wear hearing protection. Vibration total values (triax vector sum) determined according to EN62841.

Equivalent chiselling value

• Vibration emission value ah, CHeq = 10.1 m/s2
• Uncertainty K = 1.8 m/s2

The declared vibration total value and the declared noise emission value have been measured in accordance with a standard test method and may be used for comparing one tool with another. They may also be used in a preliminary assessment of exposure.

WARNING

• The vibration and noise emission during actual use of the power tool can diff er from the declared total value depending on the ways in which the tool is used especially what kind of workpiece is processed; and
• Identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).
