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, fire 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
1. Keep work area clean and well lit. Cluttered or 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 or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to
lose control.
Electrical safety
4. 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. Unmodified plugs and matching outlets will
reduce risk of electric shock.
5. 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.
6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
7. 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.
8. 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.
9. 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.
10. Use of power supply via a RCD with a rated residual current of 30mA or less is always
recommended.
Personal safety
11. 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.
12. 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.
13. 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 finger on the switch or energising power tools that have the switch on invites accidents.
14. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left

MH630 240V / MH631 110V Vibrating Hammer
MH630
attached to a rotating part of the power tool may result in personal injury.
15. Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
16. 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.
17. 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.
Power tool use and care
18. 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.
19. 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.
20. 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.
21. 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.
22. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts
and any other condition that may affect the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are caused by poorly maintained power tools.
23. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
24. 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 different from those intended could result in a hazardous situation.
Service
25. Have your power tool serviced by a qualified repair person using only identical replacement
parts. This will ensure that the safety of the power tool is maintained.
26. Follow instruction for lubricating and changing accessories.
27. Keep handles dry, clean and free from oil and grease.
HAMMER SAFETY WARNINGS
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 power tool by insulated gripping surfaces, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a
"live" wire may make exposed metal parts of the power tool "live" and could give the operator an
electric shock.
4. Wear a hard hat (safety helmet), safety glasses and/or face shield. Ordinary eye or sun glasses
are NOT safety glasses. It is also highly recommended that you wear a dust mask and thickly
padded gloves.

5. Be sure the bit is secured in place before operation.
6. Under normal operation, the tool is designed to produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check tightness of screws carefully before operation.
7. In cold weather or when the tool has not been used for a long time, let the tool warm up for a
while by operating it under no load. This will loosen up the lubrication. Without proper warm-up,
hammering operation is difficult.
8. Always be sure you have a firm footing. Be sure no one is below when using the tool in high
locations.
9. Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool only when hand-held.
12. Do not point the tool at any one in the area when operating. The bit could fly out and injure
someone seriously.
13. Do not touch the bit or parts close to the bit immediately after operation; they may be
extremely hot and could burn your skin.
14. Do not operate the tool at no-load unnecessarily.
15. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety data.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence
to safety rules for the subject product.
MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious
personal injury.
