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.
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 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.
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 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 and clothing
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 remove the battery pack,
if detachable, 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.
P
ower tools are dangerous in the hands of
untrained users.
e) Maintain power tools and accessories.
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.
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.

before use.
Usage: This machine is suitable for gouging on
concrete, bricks, stone and asphalt. After appropriate
accessories are installed, it can also be used for
squeezing and tamping.
INSTALLATION
Warning: Be sure to unplug the power
cord before any commissioning or repair
on the machine.
1. AUXILIARY HANDLE (SEE FIGURE A)
You can change the position of the auxiliary handle (8)
as needed to improve work safety and comfort.
Tighten the auxiliary handle (8) in the counter-clockwise
direction and loosen the auxiliary handle (8)in the
clockwise direction.
Warning: The auxiliary handle must be
used during operation.
2. HEXAGONAL CHISEL
With the HEX chucks (2), the hexagonal chisel can be
easily replaced without other auxiliary tools.
The dust-proof cover (1) prevents the dusts from
entering the hexagonal chisel during operation. Be
cautious when installing a hexagonal chisel without
damaging the dust-proof cover (1).
Warning: Replace the dust-proof cover
once it is damaged. To avoid danger,
it must be replaced by the special service
center, or a professional person with equivalent
qualifications.
1) Installation
Pull down the HEX chuck (2) and screw it into the
hexagonal chisel. Release the HEX chuck (2) to lock the
hexagonal chisel. (See Figure B1-B3)
Pull the hexagonal chisel to make sure it is locked.
2) Disassembly
Pull down the HEX chuck (2) and remove the hexagonal
chisel. (See Figure C)
Note: Use a sharp hex chisel to achieve good
performance. It is important to grind the
hexagonal chisel in time to extend its service
life and achieve better performance.
3) Regularly add lubricant to the gearbox
Open the oil cover with the accompanying wrench (3),
and add the appropriate amount of grease (see Figure
