INTENDED USE
The machine is intended to grind out joints of cement, in
conjunction with a dust-category M vacuum cleaner, wit-
hout the use of water.
POWER SUPPLY
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and can
only be operated on single-phase AC supply. The tool is
double-insulated in accordance with European Standard
and can, therefore be used from non-grounded sockets.
DUST EXTRACTION
Dust released when processing (grinding of
minerals) can be harmful to one's health. Tou-
ching or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infecti-
ons of the user or bystanders.
• To achieve a high degree of dust extraction, use a dust
category M vacuum cleaner for mineral dust together
with this power tool.
• Provide good ventilation of the working place.
• It is recommended to wear a FFP2 filter class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Please observe the following notes in order to reduce the
dust emissions occurring while working.
• Only use combinations of diamond joint cutters, concre-
te grinders with mounted guard and extraction hood as
well as dust category M vacuum cleaners that are re-
commended by Carat. Other combinations can lead to
insufficient dust collection and separation.
• Observe the operating instructions of the vacuum clea-
ner for maintenance and cleaning of the vacuum cleaner,
including the filter. Empty dust collection containers im-
JC-1253N
mediately once full. Clean the filters of the vacuum clea-
1700W
ner regularly and always insert the filters completely into
2 / II
the vacuum cleaner.
10.200 min-1
• Only use vacuum hoses as intended by Carat. Do not
M14
manipulate the vacuum hose. When rocks or chunks of
Ø 22,2 mm (7/8")
stone/masonry are drawn into the vacuum hose, cease
Ø 115 mm
work and clean the vacuum hose immediately. Prevent
3,3 kg
the vacuum hose from being bent or creased.
• Use the concrete grinder only as intended for.
• Observe the general requirements for construction sites.
• Provide for good ventilation.
• Ensure that the work area is free of obstructions. For lon-
ger grinding jobs, the vacuum cleaner must be able to
move along freely and at the right time.
• Wear hearing protection, protective goggles, a dust
mask and gloves as required. As dust mask, use at least
a particle-filtering class FFP 2 half-mask.
• Use a suitable vacuum cleaner for cleaning the work-
place. Prevent settled dust from being swirled up by
sweeping.
ASSEMBLY INSTRUCTIONS
Mounting the diamond joint cutter
This power tool is not intended to be used in combinati-
on with other tools than diamond joint cutter. The guard
doesn't supply suitable protection for tools other than di-
amond joint cutter.
The arbor of the diamond joint cutter must fit the mounting
flange. Do not increase the arbor of the diamond joint cut-
ter. Do not use reducers or adapters.
The permissible speed (rpm) of the diamond joint cutter
used must be at least the 10.200 per minute.
Always select a type diamond joint cutter suitable for the
specific material to be grinded. We advise diamond joint
cutters from Carat. Observe the manual of the joint cutters.
Make sure the diamond joint cutter is rotating in the correct
direction. Verify the direction of the arrow on the diamond
joint cutter is corresponding the direction of the arrow on
the power tool.
Clean the grinder spindle and all parts to be mounted
before you start. Verify the condition of the flanges and
diamond joint cutter. The supporting surfaces between the
flanges and the diamond joint cutter must be clean and
fit well.
Pull the mains plug of the power tool from the
socket, before any work on the machine itself!
