Safety
General safety and power tool warnings
WARNING
All safety warnings and instructions must be read.
Failure to comply with safety warnings and instructions may result in electric shock, fire and/or
serious injury.
All safety warnings and instructions must be kept for future reference.
The term used in safety warnings "power tool" refers to power tools operating with mains
connection (with power supply cable) and power tools operating with batteries (without power
supply cable).
1) Safety in the workplace
a) The work environment must be kept clean and well lit.
Clutter and unlit workspaces can lead to injuries.
b) With the power tool you have to work in an environment where there is no
danger of explosion, and where there are no liquid, gaseous or powdered
flammable substances.
Power tools cause sparks that could ignite dust or vapours.
c) When using the power tool it is necessary to keep children and other people at
a distance.
Distraction can cause you to lose control of the equipment.
2) Electrical safety
a) The connection plug of the power tool must be able to enter the power socket.
No changes must be made to the plug under any circumstances. No adapter
plug should be used in conjunction with power tools that are grounded.
Unmodified plugs and suitable power outlets reduce the risk of electric shock.
b) You must prevent your body from coming into contact with grounded surfaces,
such as pipes, heaters, stoves and refrigerators.
There is a high risk of electric shock if the body of the operator is grounded.
c) Power tools should be kept away from rain and moisture. The penetration of
water into a power tool increases the risk of an electric shock.
d) The cable must not be used for purposes unrelated to its function, such as
dragging the power tool, hanging it or pulling it out of the socket. The cable
must be kept away from heat sources, oils, sharp edges or moving parts of the
equipment.
Damaged or twisted cables increase the risk of electric shock.
e) If you are working with an electric tool in the open air, you should only use
extension cables that are also suitable for outdoor use. The use of an extension
cable suitable for outdoor use reduces the risk of electric shock.
f) If the use of the power tool in a humid environment is unavoidable, then it is
necessary to use a safety circuit breaker for fault currents. The use of a safety
circuit breaker for fault currents (FI RCD switch with maximum opening current of 10
mA) reduces the risk of electric shock.

CAROMAX 1800 ASP

Safety
3) Personal safety
a) It is recommended to be cautious and to pay close attention to what you are
doing, and it is recommended to proceed rationally when you are working
with a power tool. You should not use any electrical tools when you feel tired,
or when you are under the influence of drugs, alcohol or medicines.
Any drop in attention during the use of the power tool can have very serious
consequences.
b) Personal protective equipment and goggles must be worn at all times.
The risk of injury is reduced by wearing personal protective equipment, such as dust
mask, non-slip safety shoes, protective helmet and hearing protection, depending on
the type of power tool and its use.
c) Unintentional commissioning must be avoided. It is necessary to ensure that
the power tool is switched off, before connecting it to the power supply and/or
before connecting the battery, and also before picking it up or transporting it. If
you have your finger on the switch during the transportation of the power tool, or if the
equipment is already powered when it is connected to the mains power, then this can
result in accidents.
d) Adjusting tools or nut wrench must be removed before turning on the power
tool.
A tool or wrench that is in a rotating component of the equipment can cause injury.
e) You should avoid working in an unnatural position of the body. You must
always work in a safe position, always maintaining a balanced position. In this
way you can better control the power tool in unexpected situations.
f) Suitable clothing must be worn. Loose clothing or jewellery should not be
worn. Hair, clothing and gloves should be kept away from moving parts.
Loose clothing, jewellery or long hair can get caught in moving parts.
g) If dust extraction and dust collection devices can be fitted, then it is necessary
to ensure that they are connected and used correctly.
The use of a dust extraction system can reduce the dangers caused by dust.
4) Use and treatment of the power tool
a) The machine must not be overloaded. Specially suitable power tools must be
used to carry out the work.
By using the right power tools, you can work better and more safely in the
corresponding operating space.
b) No power tool should be used if the on/off switch fails. A power tool that can no
longer be switched on or off is dangerous, and must be repaired.
c) The plug must be removed from the socket and/or the battery removed before
adjusting the equipment, before replacing accessory components, or before
putting the equipment away.
This precautionary measure prevents unintentionally starting up the power tool.

CAROMAX 1800 ASP

Safety
d) When not in use, power tools should be stored in a place that is not
accessible to children. This equipment should not be used by persons who
are not familiar with its operation, or who have not read these instructions.
Electrical equipment is dangerous if it is used by inexperienced people.
e) Maintenance and care of the power tool must be carried out meticulously. It is
necessary to check that the moving parts work flawlessly and do not jam. It is
also necessary to check for broken or damaged parts that could affect the
correct functioning of the power tool. Damaged parts must be repaired before
the equipment is used.
The cause of many accidents is due to poor maintenance of electrically operated tools.
f) Cutting tools must be kept sharp and clean.
If cutting tools with sharp edges are subjected to careful care and maintenance, then
they jam more rarely and are more easily handled.
g) The power tool, accessories, spare tools used, etc. must be used in accordance
with these instructions. In this respect, account must be taken of the working
conditions and the activity to be carried out. The use of power tools for applications
other than those intended may cause dangerous situations.
5) Service
a) The power tool must be repaired only by qualified personnel, and only with
original spare parts.
This ensures that the safety of the power tool is maintained.
Machine-specific safety warnings
➢Service personnel requirements
•People under the age of 16 cannot use this machine.
➢Safety in the workplace
•The work space must be protected, even behind perforated walls.
Unprotected workspaces can pose hazards to the operator and other people.
•It is necessary to pay attention to the uncovered and hidden pipelines of
electricity, water and gas. You must use research equipment suitable for locating
hidden power lines, or you must contact the corresponding local supply company.
Contact with electrical cables can cause fire and electric shock. Damage to a gas
pipeline can cause an explosion. Drilling into a water pipe causes material damage, or
can cause electric shock.
•The workpiece must be protected.
It is best to clamp the workpiece with fasteners, or with a screw vice, rather than with
your own hand.
•The formation of dust in the workplace must be avoided.
Powders are highly flammable.
•Sufficient air flow and ventilation must be provided indoors.
Danger resulting from the formation of dust and reduced visibility.

CAROMAX 1800 ASP

Safety
•Powders from certain materials such as paints containing lead, certain types of
wood, minerals and metals can be harmful to health and can cause allergic
reactions, respiratory diseases and/or cancer.
Materials containing asbestos must be processed exclusively by qualified personnel.
– Every effort must be made to use a dust extraction system suitable for the material
in question (e.g. the special dust catcher by MAXIMA).
– Good ventilation of the workplace must be ensured.
– It is recommended to wear a respiratory mask with filter class P2 and/or P3
(according to DIN EN 149:2001).
The regulations in force in your country must be respected with reference to the
materials to be processed.
•Power tools must not be used in the vicinity of combustible materials.
Sparks could ignite these materials.
•You should avoid the presence of points where people could trip over cables.
Falling caused by the presence of cables can cause serious injuries.
➢Electrical safety
•This power tool can only be operated, for water coring, with a flawlessly
functioning PRCD circuit breaker for the protection of people (see page 17).
•Before commissioning the power tool, it is essential to ensure that there is a
protective conductor (PE) that works flawlessly.
•Before using the machine, it is necessary to check for damage to the power
tool, connection line and plug each time.
If equipment is damaged, then it is dangerous and is no longer safe for operation.
•The mains voltage must be observed! The mains voltage of the current
source shall match the information on the rating plate on the model of the
power tool.
•If the power tool is put into operation with mobile power generators, then
power losses or unusual behaviour may occur at the time of start-up.
•The power tool should not be used when the cable is damaged. You should not
touch the damaged cable and if the cable is damaged during the course of the
work, then you should pull out the electric current plug.
Damaged cables increase the risk of electric shock.
•Only extension cables suitable for the power of the machine, and with a
minimum gauge of 1.5 mm2 must be used. If a cable drum is used, then the
cable must always be unwound completely.
The wound cable can overheat a lot and start burning.
•The ventilation air slot should be kept periodically clean by blowing when the
power tool is dry. Under no circumstances should screwdrivers or other
objects be inserted into the ventilation air slot. The ventilation air slot should
not be covered.
The motor-driven fan extracts dust into the housing, and considerable buildup of
metal dust can cause electrical hazards.

CAROMAX 1800 ASP

Safety
•The power tool can automatically switch off in the event of external
electromagnetic malfunctions (e.g. mains voltage fluctuations, electromagnetic
discharges).
In this case the power tool must be switched off and on again.
•Before using the machine, it is necessary to check all the water supply
components –even those of the accessories –every time to ensure that they
are in impeccable and airtight conditions.
Water leakage increases the risk of electric shocks.
➢Personal safety
•Personal protective equipment should always be worn, and depending on the
situation the following should be used:
Full face protection mask, eye protection or goggles, protective
helmet and special protective apron.
It is necessary to protect yourself from any flying objects by wearing a
protective helmet, goggles or protective mask, and if necessary also
wearing an apron.
Hearing protection
During the course of the work, the typical sound pressure level
classified in class A of this electrical equipment is above 85 dB (A).
When you are exposed to loud noise, there is a risk of hearing damage
and/or hearing loss.
Dust mask, mouth and nose filter mask or respiratory protection
mask
Breathing in very fine mineral powders can pose health hazards. It is
recommended to wear a respiratory mask with filter class P2 and/or P3
(according to DIN EN 149:2001).
Water drilling: Drilling with the diamond core drill tube is a grinding
process during which very fine powders are generated, which are
captured by the supply water. If the water used with the captured
powder is not collected, then the powders are released again after
drying. Drilling quartz materials
the risk of silicosis is very high, and therefore in principle the machine
can only be used together with the MAXIMA water adapter, the centring
plate and a suitable water suction device (e.g. the special dust catcher
by MAXIMA).
Dry drilling: Drilling with the diamond core drill tube is a grinding
process during which very fine powders are generated. Drilling quartz
materials poses a very high danger of silicosis, and therefore in
principle the machine can only be used together with the suction hose
and a suitable dust extraction device installed (e.g. a special dust
catcher by MAXIMA).
Vibration protection gloves
With a reaction value A (8) for hand-arm vibrations greater than 2.5
m/s2 it is recommended to wear vibration protection gloves.
Vibration can pose health hazards.

CAROMAX 1800 ASP

Safety
Non-slip safety shoes
•In case of the presence of other people, care must be taken that they keep a safe
distance from the operator's work area. Anyone entering the work area must
wear their own personal protective equipment.
Fragments of the part or broken spare tools can be thrown and cause injuries even
outside the work area.
•The equipment should only be held in the hand by the insulated surfaces of the
handle, if work is carried out in the course of which the spare tools used could
come into contact with hidden power cables or with your own power supply
cable.
Contact with a live line can also power metal components of the equipment and can
cause an electric shock.
•The power supply cord must be kept away from the spare tools that are in
operation.
Loss of control of the equipment may result in breakage of the power cord, or the cord
may become entangled, resulting in the operator's hand or arm coming into contact with
the spare tool used that is rotating.
•The power tool should never be put down before the spare tool has stopped
completely.
The spare tool that is rotating could come into contact with the support surface,
resulting in loss of control over the electrical equipment.
•The power tool must not be placed in operation while it is being transported.
The operator's clothes can become entangled in the spare tool that is rotating, due to
random contact, and thereby possibly piercing the operator's body.
•Spare tools that are used with the machine running must never be turned
towards parts of one's own body or towards parts of someone else's body, and
must not even be grazed or touched.
•The On/Off power switch must be switched to the Off position, if the power
supply is cut off, for example due to a power failure, or as a result of the plug
being removed from the socket.
This prevents it from starting back up again in an uncontrolled manner.
➢Hazards related to the operation and use of the power tool
•If the machine is used for freehand drilling, then during start-up and during the
course of work, the machine must always be held in place with both handles.
(The extra handle must be screwed on firmly to the machine!) During start-up and
during the course of work, moments of reaction of the machine must be taken
into account (e.g. following sudden jamming or breakage of the spare tool).
•If freehand drilling is performed, then the On/Off switch should not be
locked.

CAROMAX 1800 ASP
10
Safety
• No accessories shall be used that the manufacturer has not explicitly
prescribed and recommended for this power tool.
The mere fact that the accessory can be attached to your power tool is in no way a
guarantee of safe use.
• The permissible speed of the spare tool used must be at least as high as the
maximum speed indicated on the power tool.
Accessories that spin faster than allowed can shatter and get thrown.
• The spare tool that is used must be replaced with the utmost care, and can only
be carried out with suitable and defect-free mounting tools. Before replacing
the spare tool that is being used, it is necessary to pull out the electric current
plug. By using the specially provided mounting tools, damage to the power tool and
the spare tool being used can be avoided.
• No damaged spare tools should be used. Before each use, it is necessary to
check for chips and cracks on the spare tools that are used. If the power tool or
spare tool falls, then you should check whether it has been damaged, or you
must use another undamaged spare tool. After checking and inserting the
spare tool, the operator and any persons in the vicinity must remain out of the
range of operation of the rotating spare tool, and the power tool must run for
approximately one minute at maximum rpm.
In most cases damaged spare tools break down during this test phase.
• Power tools should not be exposed to excessively high or excessively low
temperatures.
In the case of excessively high or excessively low temperatures, mechanical damage
and electrical damage could occur.
• After use, spare tools, tool holders and other components must be allowed to
cool in the immediate vicinity of the working area. After use, the equipment can
be red-hot, and the components must not be grazed or touched: there is a risk of
injury.
• Additional plates or specific non-original MAXIMA parts must not be screwed or
nailed to the motor housing, handle, gears or even to the protective housing.
This can result in damage to the power tool, and malfunctions may occur.
• The operator should never bring his/her hand in the vicinity of the spare tools
that are rotating.
In case of recoil, the spare tool used can move in the hand of the operator using it.
• Unnecessary noise must be avoided.
• It is necessary to pay attention to the safety warnings and work instructions of
the accessories that are used.

Machine features
The diamond core drill is equipped with a special electronic system with soft start
It monitors the number of revolutions, and with the red / green indicator lights it helps to
achieve the most favourable performance of the work, resulting in work conditions that help
reduce tool wear.
Optical display
Green: optimal rom for drilling performance.
Green / red: rpm within the tolerance margin.
Red: rpm too low, powering off.
If this alarm signal is not observed, i.e. if advancement is not reduced, then the
electronic system triggers the disconnection due to overload. After stopping it is possible
to extract the core drill tube from the drilled hole. The machine can be restarted
immediately.
These machine models are also equipped with a soft percussion device that can be
activated. It reduces the wear of core drill tube segments, allows the operator to work
more quickly and transports drilling powder away from the core drill tube segments,
resulting in a longer-lasting use of core drill tubes.
The diamond core drill is equipped with a protective circuit breaker (PRCD).
