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.
The rotational speed of this machine is adjustable. Depen-
ding on the mounted diamond joint cutter and the material
to be grinded, it may be desirable to reduce the rotational
speed.
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 fi lter 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, concrete
grinders with mounted guard and extraction hood as well
as dust category M vacuum cleaners that are recommen-
ded by Carat. Other combinations can lead to insuffi cient
dust collection and separation.
• Observe the operating instructions of the vacuum clea-
ner for maintenance and cleaning of the vacuum clea-
ner, including the fi lter. Empty dust collection containers
immediately once full. Clean the fi lters of the vacuum
cleaner regularly and always insert the fi lters completely
into the vacuum cleaner.
• Only use vacuum hoses as intended by Carat. Do not
manipulate the vacuum hose. When rocks or chunks of
stone/masonry are drawn into the vacuum hose, cease
work and clean the vacuum hose immediately. Prevent
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-fi ltering 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
Pull the mains plug of the power tool from the
socket, before any work on the machine itself!
Mounting the diamond joint cutter
This power tool is not intended to be used in combina-
tion with other tools than diamond joint cutter. The guard
doesn't supply suitable protection for tools other than dia-
mond joint cutter.
The arbor of the diamond joint cutter must fi t the mounting
fl ange. 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 10.000 per minute.
Always select a type diamond joint cutter suitable for the
specifi c 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.
