PERSONAL SAFETY
WARNING: The MZ-350 is a dangerous machine to work
with.
Read all operating and safety instructions
before using the machine. Follow the instruc-
tions strictly for your own safety and always
keep these with the machine.
To avoid dangerous situations, it is extremely important
to work fully concentrated and always keep a good view
on the work area. When using the machine for extended
periods of time, or in a repetitive way, the concentration
can weaken. To avoid this take pauses on a regular base.
You must be at least 18 years old to use the machine.

INTENDED USE
The MZ-350 wall-saw machine is a handy tool to cut brick
walls, concrete walls and floors with the help of diamond
cutting blades.
This machine is not suitable for continuous use. For this
purpose we suggest the use of a professional wall-saw
machine on rail. The MZ-350 diamond grinding machine
can be used with water-cooling, dry with dust-extraction or
with water-cooling and direct extraction.
POWER SUPPLY
The MZ-350 may only be connected to the voltage which is
stated on the serial plate and only works with 1- phase AC
voltage. The machine is insulated according to European
Guidelines and consequently may only be used via a trip
switch (PRCD) with an under voltage safety level of < 10 mA
on an earthed electrical mains.
DUST EXTRACTION
When working without dust extraction,
wearing a dust mask is mandatory.
Dust released when processing (grinding or cutting of
minerals) can be harmful to one’s health. Touching or
breathing-in the dusts can cause allergic reactions and/or
lead to respiratory infections 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 with.
Please observe the following notes in order to reduce the
dust emissions occurring while working.
• Only use combinations of diamond cutting tools,
wall saw machines with mounted guard and extraction
hood as well as dust category M vacuum cleaners that are
recommended by CARAT. Other combinations can lead to
insufficient dust collection and separation.
• Observe the operating instructions of the vacuum
cleaner for maintenance and cleaning of the vacuum
cleaner, including the filter. Empty dust collection
containers immediately once full. Clean the filters of the
vacuum cleaner regularly and always insert the filters
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 wall saw machine 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
longer grinding jobs, the vacuum cleaner must be able to
move along freely and at the right time.
