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.
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 infl u-
ence 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 protec-
tion 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, picking up or carrying the tool. Carrying power
tools with your fi nger 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 these devices
can reduce dust related hazards.
h) Do not take your safety for granted and ignore the safety rules for power
tools even if you are very familiar with the power tool after frequent use.
Careless handling can lead to severe injury within split seconds.
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 before making any adjustments,
changing accessories, or storing power tools. Such preventive safety meas-
ures 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) Look after the power tools and accessories carefully. Check for misalign-
ment 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 power tools, accessories and insert tools etc. according to these
instructions. Take the working conditions and activity being performed into
consideration. The use of power tools for purposes for which they are not intended
can lead to dangerous situations.
h) Keep handles and gripping surfaces dry, clean and free from oil and grease.
Slippery handles and gripping surfaces prevent safe handling and control of the
power tool in unforeseeable situations.
5) Service
a) Have your power tool serviced by a qualifi ed repair person using only
identical replacement parts. This will ensure that the safety of the power tool
is maintained.
Safety instructions for electric diamond core drilling
machines
WARNING
Read all the safety notes, instructions, illustrations and technical data which
come with this power tool. Failure to heed the following instructions can lead to
electric shock, fi re and/or severe injuries.
Keep all safety notes and instructions for the future.
● Only connect the power tool of protection class I to a socket/extension lead
with a functioning PE conductor. There is a danger of electric shock.
● Never use the power tool without the PRCD fault current circuit breaker
included. The use of a fault current circuit breaker reduces the risk of electric
shock.
● Always check the PRCD fault current circuit breaker before starting drilling.
The use of a fault current circuit breaker reduces the risk of electric shock.
● Never loosen the locking screw for the earth cable under any circumstances
(Fig. 9 item 59). A correctly connected earth cable reduces the risk of electric
shock.
● Only hold the power tool by the insulated handles when performing work
where the diamond core drilling crowns can come into contact with concealed
electric cables or its own power cable. Contact with a live cable can also put
metal parts of the power tool under voltage and lead to electric shock.

● Check the areas concerned for concealed supply lines with a suitable fi nder
before drilling. Drilling can damage or sever gas or water pipes, electric cables
or other objects. Damaged gas pipes can cause explosions. Damaged water
pipes and electric cables can damage property or cause electric shocks. If you
do damage a water pipe, make sure that no water gets into the motor.
● Make sure that no water gets into the drive unit motor during operation.
There is a risk of injury by electric shock if water should penetrate.
● Never use the electric diamond core drilling machines for overhead work.
There is a risk of injury by electric shock if water should penetrate.
● Cease operation immediately in case of leaks in the water supply and fi x
the leak. Do not exceed a water pressure of 4 bar. There is a risk of injury by
electric shock if water should penetrate the motor.
● Do not operate the power tool in an explosive environment. Fumes or liquids
can ignite or explode.
● Clean the air vents of your power tool regularly. The motor fan draws dust
into the housing and a heavy accumulation of metal dust can cause injury due
to electrical hazards.
● Wear personal safety equipment. Use full face protection, eye protection
or protective glasses depending on the application. Where appropriate,
wear a dust mask, ear defenders, protective gloves or a special apron which
keep away grinding and material particles and protect you against sharp
edges and wear non-slip shoes to avoid injury from slippery surfaces. The
eyes should be protected against fl ying foreign bodies which occur in different
applications. Dust masks and respirators must fi lter the dust produced in the
application. Prolonged exposure to loud noise can lead to loss of hearing.
● Use the brace (12) provided with the drill for hand-held drilling. Losing control
of the power tool can cause injuries.
● Always be prepared for blocking of the diamond core drilling crown. Never
use stage 1 for hand-held drilling with ROLLER'S Centro SR. There is a danger
of injury from the power tool being torn from the hand and spinning round as the
torque increases.
● Do not lock the safety inching switch (21) for hand-held drilling. There is a
danger of injury from the power tool being torn from the hand and spinning round
as the torque increases. The power tool can then only be brought to a standstill
by pulling out the mains plug.
● Never put down the power tool until the diamond core drilling crown has
come to a complete standstill. Rotating diamond core drilling crowns can make
contact with the surface on which you put down the tool, causing you to lose
control of the power tool.
● Keep the connecting lead away from rotating diamond core drilling crowns.
If you lose control over the tool, the connecting lead could be severed or caught
and your hand or arm could get into the rotating diamond core drilling crown.
● Protect the working areas; on both sides in case of through-bores. A drilling
core could fall out and injure persons and/or cause damage.
● Make sure that the building statics are not negatively infl uenced by the
core drilling. Consult the building supervisors or a static engineer to determine
and mark the core drilling.
● Check where the bore water fl ows to in case of hollow parts. Damages (e.g.
frost damage) could be caused.
● Only use the power tool for dry drilling in connection with a suitable safety
vacuum cleaner/dust extractor. When working with mineral building materials,
e.g. concrete, steel-reinforced concrete, all types of masonry, all types of screed,
natural stone, a high degree of mineral dust containing quartz is produced which
is harmful to the health. Inhalation of quartz fi ne dust is harmful to the health.
The Directive 89/391/EEC on the taking of measures to improve the safety and
health protection of employees at work obliges the employer to carry out an
appropriate risk assessment at the employees place of work, determine and
evaluate the potential dust load and defi ne necessary protective measures. The
German technical ruling for hazardous substances TRGS 559 "Mineral Dust"
defi nes in Appendix 1 that work with slitting and cutting machines must be clas-
sifi ed in exposure category 3 if the effectiveness of the extraction has not been
proven. In accordance with EN 60335-2-69 a penetration level of < 0.1 % is
prescribed for sucking health hazardous dusts with an exposure limit/work place
limit (AGW) of > 0.1 mg/m³. For dry drilling of mineral building materials at least
one safety vacuum cleaner/dust extractor or dust class M should therefore usually
be used in order to effectively extract the harmful dusts from machines. In addi-
tion, the respective national safety provisions, rules and regulations valid for the
application site must be considered and observed.
● Do not aim liquid jet at the power tool, not even for cleaning. Penetration of
water into the power tool increases the risk of electric shock.
● Pull the plug out of the socket before making device settings or changing
accessories. Many accidents are caused by accidental starting of power tools.
● Do not use the power tool if it is damaged. There is a danger of accident.
● Never let the power tool operate unattended. Switch off the power tool, pull
out the mains plug and remove all hoses during longer work breaks. Elec-
trical devices can cause hazards which lead to material damage or injury when
left unattended.
● Children and persons who, due to their physical, sensory or mental abilities
or lack of experience and knowledge are unable to operate the power tool
safely may not use this power tool without supervision or instruction by a
responsible person. Otherwise there is a risk of injury due to false operation.
● Only allow trained persons to use the power tool. Apprentices may only use
the power tool when they are over 16, when this is necessary for their training
and when they are supervised by a trained operative.
● Check the power cable of the power tool and extension leads regularly for
damage. Have these renewed by qualifi ed experts or an authorised ROLLER
customer service workshop in case of damage.
