d) Do not abuse the cord. Never use the cord for carrying, pulling or unplug-
ging the power tool. Keep cord away from heat, oil, sharp edges or 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.
C) Personal safety
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
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 influ
-
ence of drugs, alcohol or medication.
A moment of inattention while operating
power tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection.
Safety equipment such
as dust mask, non skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off position before
plugging in.
Carrying power tools with your finger on the switch or plugging in
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) Only allow trained personnel to use the power tool.
Apprentices may only
operate the power tool when they are over 16, when this is necessary for their
training and when they are supervised by a trained operative.
D) 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) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools
operation. If damaged, have the power tool repaired by a qualified expert
or by an authorised ROLLER after-sales service facility 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) Secure the workpiece.
Use clamps or a vice to hold the workpiece. This is safer
than holding it with your hand, and also it frees both hands to operate the equip-
ment.
h) Use the power tool, accessories and tool bits etc., in accordance with these
instructions and in the manner intended for the particular type of power
tool, 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. All unauthorised modifications to the power tool are
prohibited for safety reasons.
E) 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.
b) Comply with maintenance instructions and instructions on tool replace-
ments.
c) Regularly check the connecting cable of the electrical device. If the connecting
cable needs to be replaced, this must be done by the manufacturer or his
representative to avoid a safety risk. Check extension cable regularly and
replace it when damaged.

drilling machines Centro S1, Centro S3, Centro SR and
Centro S2/3.5
DANGER
● Only hold the drive machine by the insulated grips provided when drilling, if the
drilling accessory can come into contact with concealed cables or its own cable
when drilling. If the drilling accessory hits a power cable, unprotected metal parts
of the power tool can conduct electricity, causing the user to suffer an electric
shock.
● The locking screw (Fig. 9, item 59) for the earthing cable may never be loosened
otherwise there is acute danger to life!
● You could hit concealed power cables when drilling. Check first with a test device!
WARNING
● Use the additional handles supplied with the device. Losing control of the machine
can cause injuries.
● Use only electrical plugs with shockproof socket. Check the earth (ground)
connection of the plug.
● Use only extension leads with shockproof socket.
● Never use the drive unit without the PRCD fault-current safety switch supplied.
● Always check the PRCD fault-current safety switch for correct functioning before
starting a drilling operation (see 3.).
● When drilling, hold the drive unit only by the insulated handles provided for the
purpose.
● Ensure that no water is allowed to get into the drive unit during operation.
● If you detect a leak in any part of the water supply system, shut the machine
down immediately and repair the fault. Water pressure should not exceed 4 bar.
● Have the core drilling operations marked out by the person in charge of operations.
● The statics must not be negatively influenced in any way by the core drilling work,
consult site management or the engineer engaged in statical calculations if
necessary.
● Take care not to damage gas, water, power and other conduits in the area of the
drilling operation. Drain or shut off these conduits as required.
● Block off the working area and place warning signs on both sides of the wall
when drilling through from one side to the other.
● Take appropriate precautions to ensure that, in the event of a drilling core drop-
ping out, no personal injury or material damage will result.
● When handling hollow components, check the flow route of the diluted soluble
oil in order to prevent damage (e.g. from frost).
● Note that the diamond core drilling crowns can become blocked at any time.
During manually controlled core drilling, there is a danger of the drive unit jumping
out of your hands.
● Do not attempt to work above shoulder height with electrically-driven core drilling
machines.
● Do not lock the switch (21) during free-hand drilling.
● Pull the plug out of the socket before making device settings or changing acces-
sories. Many accidents are caused by accidental starting of power tools.
Special safety instructions for ROLLER’S drill stands
S 2 and T
WARNING
● Pull the plug out of the socket before making device settings or changing acces-
sories. Many accidents are caused by accidental starting of power tools.
● Set up the stand correctly before mounting the power tool. Correct assembly is
important to prevent the risk of collapsing.
● Fix the power tool securely to the stand before use. Slipping of the power tool
on the stand can lead to loss of control.
● Fix the stand to a firm, level surface or wall. The power tool cannot be guided
evenly and safely if the stand can slip or shake (see 3.3.).
● Do not overload the stand or use it as a ladder or scaffold. Overloading or standing
on the stand can shift the centre of gravity of the stand upwards and cause it to
tip over.
Use for the intended purpose
WARNING
Use the ROLLER’S electric diamond core drilling machine for the intended purpose
of core drilling in steel-reinforced concrete, masonry and other materials, dry or wet
drilling, hand-held or with drill stand.
