Special safety warnings
The term "disc" in the safety instructions
means a "diamond cutting disc" and a pair
of the cutting discs�
• The power tool is designed for cutting of solid min-
eral materials (for example, concrete, brickwork etc�)�
Do not use the power tool to cut any wood, plastic or
metal� The user must be responsible for any hazard
caused by improper use only� Carefully understand ac-
cident safety protection rules and safety instructions�
• The tool shall be used for dry operation only.
• Please hold insulating surface of the power tool dur-
ing operation since the cutting tool may contact hidden
line or built-in line� Contact with "live" line may make
metal part of the tool "electrified", and cause electric
shock to the operator�
Please pay special attention to following
warnings for personal safety and tool
maintenance.
• Do not use any grinding disc�
• Do not use diamond cutting disc not conforming to
provisions of the manufacturer�
• Do not use damaged, deformed or cracked diamond
cutting disc�
• Do not work with the protective cover removed or
with the front cover removed�
• Do not turn on the power tool if the diamond cutting
discs are in contact with the workpiece�
• After the power tool has been turned off, it can be set
aside only after a full stop of the diamond cutting discs�
Do not try to slow down the rotation of the diamond cut-
ting discs by pressing them against any surface�
• Before replacing the diamond cutting disc, adjusting
the depth or width of the cutting, and also before ser-
vicing the power tool, remove the plug of the current-
carrying cable from the power outlet� Diamond cutting
discs should not rotate�
• For operation in the occasion where the diamond
cutting disc may cut the hidden line or built-in line,
hold the power tool through the insulated holding sur-
face� Contact of diamond cutting disc with live con-
ductor may make exposed metal parts of the power
tool electrified and cause electric shock to the opera-
tor�
• For "blind cutting", be careful particularly when en-
tering the wall or other dead zone� The diamond cut-
ting disc may cut the gas pipe or water pipe, wire or
cause object on the rebound�
• Always keep your hands at a sufficient distance from
the cutting area and the diamond cutting discs� The
second hand must always hold the auxiliary handle�
• Always use diamond cutting discs of the proper size
and with the proper shape of the bore� If the bore of the
diamond cutting disc does not coincide with the clamp-
ing parts of the power tool, the lack of alignment will
lead to loss of control�
• Do not use fasteners for the diamond cutting discs
(flanges, bolts, etc.) that are damaged, or fasteners of
the wrong size� This may cause loss of control of the
power tool�
• Please always wear the safety goggles and ear
muff�
• Please wear additional protective equipment for per-
sonal safety, such as protective gloves, solid footware,
safety helmet and work apron�
• Please do not touch the wire if the power wire is
damaged or cracked during operation, pull the plug im-
mediately, and do not use power tool with damaged
wire�
• Please put the wire behind the power tool during
operation�
• Check to see whether there is any concealed line or
pipeline within the range of operation with appropriate
detector, and request support from local construction
unit whenever necessary� Fire and electric shock may
be caused if the cable wire is cut through during opera-
tion� Damage to gas pipe may cause explosion� Cutting
off the water pipe may cause financial loss and make the
power tool operator subject to electric shock accordingly�
• Hold the insulated handle to operate the power tool
when operating in a hidden place with buried wire�
Metal parts of the power tool may be electrified in case
that the power tool is in contact with "live" cable, and
electric shock will be caused thereby�
• Install and use the diamond cutting discs as recom-
mended by the manufacturer�
• The permissible speed of the diamond cutting discs
must be not less than the idling speed of the power
tool�
• Before use, check the integrity of the diamond cut-
ting discs� Install the diamond cutting discs correctly�
Make sure that the diamond cutting discs do not rub
against any parts during operation� After installation,
turn on the power tool and let it idle for at least 30 sec-
onds� Do not use damaged or deformed diamond cut-
ting discs, as well as discs that have vibration or beat�
• Pay attention to the size of the diamond cutting
discs� The bore of the diamond cutting discs must ex-
actly match the shape and size of the flange.
• Handle the diamond cutting discs with care� Protect
them from shocks, jolts or grease�
• Do no process materials containing asbestos�
• Fix the workpiece� Clip the workpiece more safely
and steadily with fixed tooling or bench screw.
• First turn on the power tool, then bring it to the sur-
face of the material for processing� Keep both hands
well away from rotating diamond cutting discs�
• Stop the power tool immediately if powerful rebound
is caused due to jamming of the diamond cutting disc
during operation�
• Turn off the power tool before putting it off� Do not
lay down the power tool until the diamond cutting discs
have come to a complete stop�
• Do not hand over the power tool to children for op-
eration�
• We can guarantee the power tool performance if
only using accessories specified for the power tool.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating diamond cutting disc� Pinching or snagging
causes rapid stalling of the rotating diamond cutting
disc which in turn causes the uncontrolled power tool
to be forced in the direction opposite of the diamond
cutting disc's rotation at the point of the binding�
For example, if an diamond cutting disc is snagged or
pinched by the workpiece, the edge of the disc that is
entering into the pinch point can dig into the surface
of the material causing the disc to climb out or kick
out� The diamond cutting disc may either jump toward
