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.
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 flammable
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
losecontrol.
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. Unmodified 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 influence of drugs, alcohol or

6
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 finger 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 affect the power tool's 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 different from those intended could result in a hazardous situation.

5) Service
a) 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.
b) If the replacement of the supply cord is necessary, this has to be done by the manufacturer or
his agent in order to avoid a safety hazard.
Additional Safety Rules for Hammer
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 tools by insulated gripping surfaces, when performing an operation where the
cutting tool 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 dust mask.
5. Be sure the bit is secured in place before operation.
6. Under normal operation, the machine is designed to produce vibration, the screws and bolts can come
loose, causing a breakdown and accidents. Check tightness of them carefully before running.
7. In cold weather or a long time tool not be used, please keep the tool running without load a few
minutes to warm up the grease inside, otherwise hammering function is difficult to get.
8. Be sure you stand stably and no one is below when you using tool is in high location.
9. Hold the tool firmly with two hands.
10. Don't touch any moving parts.
11. Don't leave the tool running itself, operate tool only when hand-held.
12. Don't point the tool to anybody for the bit could fly out in case.
13. Don't touch the BIT OR PARTS CLOSE TO THE BIT immediately after operation, they may
extremely hot and could burn your skin.
14. Any damage and abnormal happen, please stop to use immediately and disconnect it, ask authorized
serve center to check and repair.
15. Parts replace: Only original XINPU's parts can be used to replace by authorized service center.
16. Right use accessories and parts: Don't use other parts and accessories which not mentioned in the
manual otherwise may cause injuries!
17. Special attention to voltage: Before connect the power tool, please make sure the rated voltage on
the tool can match the power supply, otherwise the power tool may be damaged and cause injuries.
18. Don't wipe plastic part with solvent: Solvent such as gasoline, thinner, alcohol etc. these kind of
chemical material, are not allowed to use, water or soap are recommended!
19. In case of damages the replacement of the plug or the supply cord shall always be carried out by the
manufacturer of the tool or his service organization
