• 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 op-
eration. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools�
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control�
• 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�
• Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations�
• Note that when you operate a power tool, please
hold the auxiliary handle correctly, which is helpful
when controlling the power tool� Therefore, proper
holding can reduce the risk of accidents or injuries�
Service
• 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�
• Follow instruction for lubricating and changing ac-
cessories�
Special safety warnings
• Reasonable use of power tool: the power tool is ap-
plicable for grooving or cutting on high mineral material
(such as marble)� 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 accident safety protection rules and safety
instructions�
• 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 operate when the fixed guard is removed.
• Do not start the power tool when the diamond cut-
ting disc is in contact with the workpiece�
• Do not put down the power tool before complete
stop of the diamond cutting disc after the power tool is
powered off, and do not use any external force to stop
the diamond cutting disc�
• Pull the plug from power source before diamond
cutting disc replacement, cutting depth or water pipe
adjustment or power tool maintenance, and make the
diamond cutting disc under the condition of rest�
• Check action reliability of RCD before operation for
power tool equipped with RCD�
• 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 surface�
Contact of diamond cutting disc with live conductor
may make exposed metal parts of the power tool elec-
trified and cause electric shock to the operator.
• 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�
• Keep hands always away from the sawing area and
diamond cutting disc� Make the other hand always hold
the auxiliary handle� Harm from the diamond cutting
disc will be avoided if holding the power tool with both
hands�
• Do not contact bottom of the workpiece� The guard
can not protect diamond cutting disc under the work-
piece�
• Always use diamond cutting disc with proper size
and axis shape (rhombic or round)� Loss of control will
be caused by eccentric operation due to unconform-
ity of diamond cutting disc with clamping parts of the
power tool�
• Do not use damaged gasket and bolt or those with
nonconforming size� Operation out of control may be
caused if using damaged gasket and bolt or those with
nonconforming size�
• 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�
• Please install and use the diamond cutting disc
in accordance with the specification provided by the
manufacturer�
• Permissible speed of diamond cutting disc shall not
be less than no-load speed of the power tool�
• Check completeness of the diamond cutting disc be-
fore using it, install the diamond cutting disc correctly,
and ensure that the diamond cutting disc will not be
subject to friction with any part during operation� Test
run of at least 30s is required under no-load condition
after installation� Do not use any damaged, deformed
diamond cutting disc or such with abnormal vibration
during operation�
• Pay attention to size of diamond cutting disc� Mount-
ing hole of the diamond cutting disc must match the
joint flange exactly.
• Protect the diamond cutting disc, and prevent the di-
amond cutting disc from any knock, collision or oil dirt�
• Do no process materials containing asbestos�
