General Power Tool Safety Warnings
WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future
reference.
The term “power tool” in the warnings refers to your
mainsoperated (corded) power tool or battery-op-
erated (cordless) power tool.
2.1 Workplace safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust.
Power tools create sparks which may ignite the
dust or fumes.
c) Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.

2.2 Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way. Do not use
any adapter plugs with earthed (grounded)
power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) Avoid body contact with earthed or
grounded surfaces, such as pipes, radiators,
ranges and refrigerators.
There is an increased risk of electric shock if
your body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions.
Water entering a power tool will increase the risk
of electric shock.
d) Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,
sharp edges and moving parts.
Damaged or entangled cords increase the risk
of electric shock.
e) When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply.
Use of an RCD reduces the risk of electric
shock.
2.3 Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the influence of drugs, alcohol or
medication.
A moment of inattention while operating power
tools may result in serious personal injury.
b) Use personal protective equipment. Always
wear eye protection.
Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will
reduce personal injuries.
c) Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or battery
pack, picking up or carrying the tool.
Carrying power tools with your finger on the
switch or energising power tools that have the
switch on invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on.
A wrench or a key left attached to a rotating part
of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and
balance at all times.
This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts.
Loose clothes, jewellery or long hair can be
caught in moving parts.
g) If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used.
Use of dust collection can reduce dust-related
hazards.
2.4 Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application.
The correct power tool will do the job better and
safer at the rate for which it was designed.
b) Do not use the power tool if the switch does
not turn it on and off.
Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) 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 operation.
If damaged, have the power tool repaired
before use.
Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.

g) 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.
2.5 Service
a) 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.
2.6 Safety Warnings for Drills
• Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
• Use auxiliary handle(s), if supplied with the
tool.
Loss of control can cause personal injury.
• Hold power tool by insulated gripping
surfaces, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may
make exposed metal parts of the power tool
“live” and could give the operator an electric
shock.
2.7 Additional safety warnings
2.7.1 Operating personnel
requirements
• People below the age of 16 may not use the
machine.
• The operating personnel must be familiar
with the content of this instruction manual.
2.7.2 Workplace safety
• Secure the work area also behind openings
and cutouts.
Unsecured work areas can endanger you and
other people.
• Watch out for open and concealed electricity
cables, and water and gas pipes. Use
suitable detectors to find concealed utility
pipes and cables, or contact the local utility
company for advice.
Contact with electricity cables can cause fires
and an electric shock. Damage to a gas pipe
can cause an explosion. Penetrating a water
pipe causes damage to property or could cause
an electric shock.
• Do not use the power tool near flammable
materials.
Sparks could ignite these materials.
• Avoid causing situations where other people
can stumble or trip.
Tripping over cables can cause serious injuries.
• Secure the workpiece.
A workpiece securely held in clamping devices
or a vice is more safely held than in the hand.
• Avoid dust accumulation in the workplace.
Dusts can easily ignite.
• Ensure adequate ventilation in closed
rooms.
Risk due to dust and impaired vision.
• Dust from materials such as coatings
containing lead, several types of wood,
minerals and metals can be harmful
to health and cause allergic reactions,
respiratory diseases and/or cancer.
Asbestos-containing material may only be
machined by specialists.
fWherever possible, use a dust extractor
suitable for the material you are working on
(e.g. a special MAXIMA dust extractor).
fEnsure the workplace is properly ventilated.
fWe recommend wearing a face mask
respirator with filter class P2 or P3
(to EN 149:2001).
Observe the relevant regulations in your country
for the materials to be machined.

2.7.3 Electrical safety
• Before each use, check the power tool,
connection cable and plug for damage.
Damaged equipment is dangerous, and no
longer safe to use.
• Note the mains voltage! The power source
voltage must match the details given on the
rating plate of the power tool.
• If using the power tool with mobile
generators, loss of power or atypical
behaviour on switching on is possible.
• Do not use the power tool if the cable is
damaged. Do not touch the damaged cable
and disconnect the mains plug if the cable is
damaged while you are working.
Damaged cables increase the risk of an electric
shock.
• Only use extension cables suitable for the
machine's power consumption and which
have a minimum core cross-section of
1.5 mm2. If you use a cable drum, always
completely unwind the cable.
The rolled up cable can heat up and start to
burn.
• Regularly clean the ventilation slots of your
power tool by blowing it out. Never use
liquids. Never insert screwdrivers or any
other objects into the ventilation slits. Do
not cover the ventilation slits.
The motor fan draws dust into the housing and
a large accumulation of metal dust can cause
electrical hazards.
• External electromagnetic interference (e.g.
mains voltage fluctuations, electrostatic
discharges) can cause the power tool to
switch off automatically.
In this case, switch off the power tool and then
switch it back on again.
• Do not use any insert tools which require
liquid coolant.
The use of water or other liquid coolants could
result in an electric shock.
2.7.4 Safety of people
• Wear personal protective equipment and,
depending on the work situation, use:
Full-face protection, eye protection
or safety glasses/goggles, hard hat
and special apron
Protect yourself against debris thrown
up by wearing a hard hat, safety gog-
gles or face protection and wear an
apron, if necessary.
Hearing protection
The typical A-weighted sound pres-
sure level of this power tool is over 85
dB (A) while working with the tool.
If you are exposed to loud noise for
lengthy periods, there is a risk of hear-
ing damage or even hearing loss.
Anti-vibration safety glove
At a release value A (8) for arm-hand
vibrations of over 2.5 m/s2, the wearing
of anti-vibration safety gloves is rec-
ommended.
Non-slip safety footwear
Dust mask, half-face filter mask or
face mask respirator
Inhaling fine mineral dust can cause
health damage. We recommend wear-
ing a face mask respirator with filter
class P2 or P3 (to EN 149:2001).
Working with dry diamond core drill
bits is a grinding process in which ex-
tremely fine dust is produced. When
cutting materials containing quartz
there is a very high risk of silicosis;
in this case the machine should only
be used in conjunction with a suitable
dust extractor (e.g. a special MAXIMA
S.p.A. dust extractor).
• Ensure other people keep a safe distance
from your work area. Any person entering
the work area must be wearing personal
protective equipment.
Broken pieces of the workpiece or broken insert
tools can fly off and cause injuries, even outside
the immediate work area.
• Keep the mains power lead away from
rotating insert tools.
If you lose control of the tool, the mains power
lead can be cut or caught and your hand or arm
can be pulled into the rotating insert tool.
• Never put down the power tool until the
insert tool has come to a complete standstill.
The rotating insert tool can come into contact
with the surface on which the power tool is
placed, which could cause you to lose control of
the power tool.
• Do not leave the power tool running while
you are carrying it.
Your clothing can get caught by inadvertent
contact with the rotating insert tool and the
insert tool can drill into your body.
• If the machine is switched on, do not direct
insert tools towards your own or other
people's bodies. Do not touch or take hold
of the tools.

2.7.5 Hazards when using and
handling the power tool
• If the machine is used for hand-held
drilling, always hold both handles firmly
when switching on and while working with
the machine. (The additional handle must
be tightly screwed onto the drill!). When
switching on and while working with the
machine, expect reaction torques (e.g. due
to sudden jamming or breakage of the insert
tool).
• Do not use any accessories, which have not
been especially provided and recommended
for this power tool by the manufacturer.
Just because you can attach the accessories
to your power tool is not a guarantee of safe use.
• The approved speed of the insert tool must
be at least as high as the maximum speed
given on the power tool.
Accessories which rotate faster than approved
can break and fly off the tool.
• Change insert tools carefully and only use
the mounting tools provided, if they are in
perfect condition. Disconnect the mains
plug before changing the insert tool.
Use of the mounting tool provided prevents
damage to the power tool and insert tool.
• Never use damaged insert tools. Before
each use, check insert tools for splinters
and cracks. If the power tool or insert tool
is dropped or falls, check whether it is
damaged, or use an undamaged insert tool.
If you have checked and inserted the insert
tool, keep yourself and other people nearby
outside the plane of the rotating insert tool
and let the power tool run at maximum speed
for one minute.
Most damaged insert tools break during this test
period.
• Do not expose power tools to extreme heat
or cold.
Mechanical and electrical damage can occur
during extreme heat and/or cold.
• Allow the insert tools, tool holders and other
parts cool in the immediate vicinity of the
work area after use.
The equipment can be very hot after use. Do not
touch or grip the parts. Risk of injury.
• Additional signs or other, non Maxima
specific parts may not be screwed or
riveted onto the motor, handle, gearbox or
protective housing.
This could damage the power tool and cause
malfunctions to occur.
• Avoid unnecessary noise emissions.
• Note and follow the safety and work
instructions for the accessories used.
2.7.6 Service / Maintenance / Repair
• If the power tool is dropped or becomes wet,
have it checked.
A possibly damaged power tool is dangerous
and no longer safe to operate. Before using
the power tool again, have it checked by our
customer service or an authorised service
centre of Maschinenfabrik MAXIMA S.p.A.
• Repair and maintenance work may only be
carried out by an authorised workshop of
Maschinenfabrik MAXIMA S.p.A.
Otherwise, all liability and warranty claims
against Maschinenfabrik MAXIMA S.p.A.
expire.
• Ensure that original MAXIMA spare parts and
original MAXIMA accessories only are used
when needed.
Original parts are available from authorised
dealers. Use of non original parts can cause
damage to the machine and an increased risk of
accidents.
• Regular servicing by MAXIMA S.p.A.
or a servicing and repair
company authorised by us is specified.
Many accidents are caused by poorly serviced
and maintained power tools.

3) Total vibration values (vector sum in three directions) determined according to EN 60745
The vibration emission values given in this instruction manual have been measured according to a method
of measurement standardised in EN 60745 and can be used for comparison between power tools. They
are also suitable for a preliminary estimate of the vibratory stresses.
The vibration emission values given represent the main applications of the power tool. If the power tool is
used for other applications, with different insert tools or are insufficiently serviced, this can significantly
increase the vibratory stresses over the whole work period. For a precise estimate of the vibration
emission values, the times during which the tool is switched off or is running but not actually in use should
also be taken into account. This can reduce the vibration stresses over the whole work period significantly.
WARNING
Health risk due to vibrations.
ÎAdditional safety measures should be taken to
protect the user, e.g. wearing anti-vibration pro-
tective gloves, correct maintenance of power
tools and insert tools, keeping hands warm and
good organisation of work sequences.

3.3 Machine characteristics
The machines are equipped with specially
developed electronics with soft start. It monitors
the speed and the green / red indicator lights
(items 1 and 2, see Figure 1 ) help to achieve the
most favourable work progress and therefore tool-
protecting working conditions.
Visual display
Green: Speed for optimum drilling
performance
Green / red: Speed within the limit range
Red: Speed too low – stopping
If this warning signal is ignored, i.e. the feed is not
reduced, the electronics switch off on overload.
After the dry diamond core drill bit has stopped,
remove it from the drill hole. The machine can be
restarted immediately.
The machine is also equipped with a selectable
soft impact mechanism. It protects the diamond
segments of the core drill bits, allows faster working
and carries the drill dust away from the diamond
segments, which in turn enables a longer tool life for
the diamond core bits.

Dust extraction for dry diamond core drill
bits with 1 ¼" connection
If dry diamond core drill bits with 1¼" connection are
used, the dust is extracted using the MAXIMA suction
rotor (available as accessory, see MAXIMA catalogue
in combination with a MAXIMA special
dust extractor.
5.3 Switching on the dry diamond
drill and drilling
NOTE
The dry diamond core drill bit can be damaged
irreparably by overheating or jamming in the core
drill hole.
If harmful dust is produced during the work, a
suitable dust extractor must be connected to
the dry diamond drill (e.g.MAXIMA special dust
extractor).
Switch the drill's soft impact feature on or off,
depending on the material to be drilled:
• Drilling with soft impact feature is
recommended for drilling in concrete and other
hard materials.
• Drilling without soft impact feature is
recommended for drilling in abrasive materials
and materials with a lower hardness.
Switching on / off the soft impact feature
• 5 Switch on soft impact feature:
Press the side of the soft impact switch marked
green (1).
• 6 Switch off soft impact feature:
Press the side of the soft impact switch marked
black (2).

NOTE
Blunt dry diamond core drill bits can be
resharpened if necessary using MAXIMA
whetstones or other suitable materials.
Note and follow the information and instructions
on handling dry diamond core drill bits (see
page 36).
5.4 Ending the drilling process
NOTE
To avoid damage to the diamond segments, do not
switch off the dry diamond drill until the rotating
dry diamond core drill bit has been completely
removed from the masonry.
• 11 The dry diamond drill switches off as soon
as the ON / OFF switch (1) is released.
Breaking out the drill core
NOTE
The dry diamond core drill bit can be damaged
irreparably if it is jammed in the core drill hole.
Never use the dry diamond core drill bit to break
out the drill core!
• 12 Use a suitable tool
to break out the drill
core in the wall.
5.3.1 Drill centring hole
• 7 /
8 Push the centring drill bit (1) with the
knurled sleeve (3) towards the front (A) and lock
by turning anti-clockwise (B).
• Switch on the dust extractor connected to the
extraction dome (2) (see “Chap. 5.2 Connecting
the dust extractor”).
• Always hold on tight to both handles of the dry
diamond drill with both hands.
• 7 /
8 Move the centring drill bit (1) into the
required position on the wall.
• 11 Press the ON / OFF switch (1) to switch on
the dry diamond drill.
• 7 /
8 Drill until the diamond dry core drill bit is
centred approx. 5 – 10 mm deep in the wall.
• 9 /
10 Switch off the machine and after it has
stopped unlock the dry diamond core drill bit
knurled sleeve (1) by turning it clockwise (A) and
allow it to snap back (B).
5.3.2 Drilling a box hole
• Leave the dust extractor connected to the
extraction dome switched on.
NOTE
The dry diamond core drill bit can be damaged
irreparably by overheating or jamming in the core
drill hole.
The feed can only be as high as the diamond dry
core drill bit can wear away the material. Therefore,
do not exert too large a force on the dry diamond
core drill bit and avoid canting.
• Feed the dry diamond core drill bit into the pre-
centred hole.
• Switch on the dry diamond drill.
• Apply a light, uniform feed pressure and
continue drilling to the required depth.
• Pull back the dry diamond core drill bit a little
now and again to remove the drill dust.
• 11 If the feed is too fast, the red LED (2) lights
up. Then, reduce the feed immediately until the
green LED (3) lights up again.
If this warning signal is ignored, i.e. the feed is
not reduced, the electronics switch off the dry
diamond drill on overload.
The drilling process can then be restarted and
continued as described above.

9 Handling dry diamond core
drill bits
• Always use and store dry diamond core drill
bits in accordance with the manufacturer's
instructions.
• Too soft diamond segments:
fDry diamond core drill bits wear too quickly
at very high removal rate.
Remedy: The material to be machined
requires dry diamond core drill bits with a
harder bond.
• Too hard diamond segments:
fThe diamond grains become blunt and do
not break out of the bond. The dry diamond
core drill bits no longer have any cutting
power.
Remedy: The material to be machined
requires dry diamond core drill bits with a
softer bond.
• If extraction is not used during machining, the
dry diamond core drill bit rubs increasingly
against “soft” drill dust. The core bit segments
heat as a result, they become soft and the
diamond splinters sink into the substrate. The
dry diamond core drill bit becomes less sharp.
The cutting performance reduces and the user
increases the pressure on the dry diamond core
drill bit, which in turn increases the effect. After
drilling a few holes, the core bit segments are
“glazed” or they tear off at the least resistance in
the stone and the dry diamond core drill bit must
be replaced.
• Sharpening the dry diamond core drill bit on the
MAXIMA professional whetstone
or on a soft stone between drilling enables
sunken in diamonds to be re-released and the
dry diamond core drill bit is sharp again.
• It is necessary to cool the drill bit segments
through extraction to extend the life of the dry
diamond core drill bit and to keep the cutting
speed high.
• Excessive drilling pressure can cause material
fatigue in the base metal and therefore the
formation of cracks. Before use, ensure that
there are no cracks in the dry diamond core drill
bit.
• 11 The dry diamond core drill bit should plunge
into the wall only after the working speed has
been reached – green LED (3) lights up.
• After approx. 2 minutes of cutting time the
machine should be run with no load for
10 seconds, so that the dry diamond core drill
bit can cool.
