2 Safety
2.1 General power tool safety warnings
WARNING Read all safety warnings, instructions, illustrations and specifications
provided with this power tool. Failure to follow all instructions listed below 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 mains-operated (corded) power tool
or battery-operated (cordless) power tool.
Work area safety
▶Keep work area clean and well lit. Cluttered or dark areas invite accidents.
▶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.
▶Keep children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
Electrical safety
▶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.
▶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.
▶Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
▶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 or moving parts.
Damaged or entangled cords increase the risk of electric shock.
▶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.
▶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.
Personal safety
▶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.
▶Use personal protective equipment. Always wear eye protection. Protective
equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce personal injuries.
▶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.
▶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.
▶Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.

*2328079* 2328079 English 7
▶Dress properly. Do not wear loose clothing or jewellery. Keep your hair and
clothing away from moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
▶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.
▶Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe
injury within a fraction of a second.
Power tool use and care
▶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.
▶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.
▶Disconnect the plug from the power source and/or remove the battery pack,
if detachable, 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.
▶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.
▶Maintain power tools and accessories. 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.
▶Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
▶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.
▶Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and control of
the tool in unexpected situations.
Service
▶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.
2.2 Additional safety instructions for wall saws
▶Operate power tool by insulated grasping surfaces, when performing an oper-
ation where the cutting accessory may contact hidden wiring or its own cord.
A cutting accessory contacting a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an electric shock.
▶Wear ear protectors when diamond sawing. Exposure to noise can cause hearing
loss.
▶When sawing through the workpiece, ensure to protect persons and the work
area on the other side. The diamond wheel may protrude through the workpiece.
▶Never leave the wall saw unattended during operation. This reduces the risk of
the diamond wheel jamming, which could cause loss of control or damage to the wall
saw.

8 English 2328079 *2328079*
▶Ensure that the method of securing the track guiding system to the workpiece
is capable of holding and restraining the machine during use. If the workpiece
is weak or porous, the anchor(s) can pull out, causing the track guiding system to
release from the workpiece.
▶If the diamond wheel becomes jammed, stop applying feed force and turn off
the tool. Investigate and take corrective action to eliminate the cause of the
diamond wheel jamming. Attempting to continue operation with a stalled diamond
wheel can lead to loss of control or damage to the wall saw.
▶Before starting, make sure that the AC supply voltage, AC supply frequency and fuse
rating correspond to the specification given on the type identification plate.
▶Check the machine’s electric supply cable at regular intervals and have it replaced by
a qualified electrical specialist if found to be damaged.
▶Check extension cords at regular intervals and replace them if found to be damaged.
▶If the electric supply cable to the saw is damaged while working, do not touch the
supply cable or the saw. Switch the wall saw off at the on/off switch or press the
EMERGENCY STOP button and unplug the supply cord from the power outlet.
▶Use only extension cables of a type approved for the application and with conductors
of adequate gauge.
▶Do not work with rolled-up extension cables. A rolled-up cable may cause a drop in
power and may result in the cable overheating.
▶Disconnect the power cable before beginning cleaning and maintenance work or in
the event of an interruption between periods of operation.
▶Drilling and sawing work on buildings and other structures may influence the statics of
the structure, especially when steel reinforcing bars and/or load-bearing components
are cut through. Approval must always be obtained from the site engineer or site
management before beginning drilling and sawing work.
▶Make sure that the workplace is adequately ventilated. Exposure to dust at a poorly
ventilated workplace may present a health risk.
▶Install suitable supports to ensure that the part cut out does not move. Blocks slipping
or falling when cut free could cause serious injury and/or damage.
▶Install suitable supports to ensure that the structure retains its stability while cutting
work is in progress and also after removal of the part cut away.
▶In cooperation with the site engineer or architect, check to ensure that no gas, water,
electricity or other supply lines are located in the cutting area. Supply lines of these
kinds present a serious risk of accident if damaged during the course of the work.
External metal parts of the machine could become live if, for example, an electric
supply cable is damaged.
▶Avoid skin contact with drilling and sawing slurry. In the event of contact with the
eyes, rinse immediately with clean water and consult a doctor if necessary.
▶Dust produced by grinding, sanding, cutting and drilling can contain dangerous
chemicals. Some examples are: lead or lead-based paints; brick, concrete and other
masonry products, natural stone and other products containing silicates; certain types
of wood, such as oak, beech and chemically treated wood; asbestos or materials
that contain asbestos. Determine the exposure of the operator and bystanders by
means of the hazard classification of the materials to be worked. Implement the
necessary measures to restrict exposure to a safe level, for example by the use of
a dust collection system or by the wearing of suitable respiratory protection. The
general measures for reducing exposure include:
▶working in an area that is well ventilated,
▶avoidance of prolonged contact with dust,

*2328079* 2328079 English 9
▶directing dust away from the face and body,
▶wearing protective clothing and washing exposed areas of the skin with water and
soap.
▶When working in dusty conditions, use a suitable dust removal system whenever
possible. Dust from materials such as concrete, masonry and stone containing quartz,
as well as minerals and metals, may present health risks. Contact with or inhalation
of the dust may cause allergic reactions and/or respiratory or other diseases to the
operator or bystanders.
▶Always lead cables and hoses flat on the ground or floor away from the machine. This
will help to reduce the risk of tripping while working.
▶Keep cables and hoses away from rotating parts.
▶Make sure that the cooling water used is drained away or collected (vacuum) in a
suitably controlled manner. Water that’s allowed to flow away or spray around in an
uncontrolled manner can lead to damage or accidents. Also remember that water
could drain away into internal, hidden cavities.
▶Don’t work from a ladder.
2.3 Safety measures at the danger areas
WARNING
A risk is presented by moving parts, by falling objects or debris that may fly off!
Falling or flying objects could cause serious injury.
▶Make sure that the area is cordoned off and that warnings to third parties are displayed.
▶Make sure that no one is present in the area immediately beneath the workplace while
work is in progress.

Safety measures must also be implemented in the area not directly visible to the operator,
i.e. at the rear of objects being cut.
Never loiter in a position directly below the equipment.
2.4 Safety during operation
▶Check the flange and saw blade for damage and degrease the blade holder each time
before putting the saw into operation.
▶Begin work with the saw only when the track supports are securely and rigidly
fastened to a solid surface and when the wall saw system has been correctly installed
(all screws tightened securely, the saw head locked securely on the track and the end
stops correctly installed).
▶Use only suitable fastening materials of adequate dimensions to fasten the track
supports and to secure the parts of the object being cut.
▶As a basic rule, never stand directly in line with the rotating saw blade.
▶Always use the appropriate, correctly fitting blade guard (type BG for normal cutting,
type BGFT for flush cutting). For dry cutting, use the blade guard for dry cutting with
dust extractor.
▶When making corner cuts that require use of a partly open blade guard, operate the
machine from the side at which the blade guard is closed, i.e. from the protected side.
When necessary, the operator must implement suitable additional safety measures.
▶Before entering the danger area, switch the wall saw off at the on/off switch or press
the EMERGENCY STOP button. Persons may enter the danger area only after the
blade drive unit has been switched off and the blade has come to a standstill.
▶Adhere to the permissible drive unit parameters and recommended guide values for
blade rotation speed and advance speed while sawing.
▶Use only saw blades that comply with the requirements of EN 13236. Observe the
information on the diameter of the arbor hole and the maximum saw blade disc
thickness in the section headed Technical data. Mount the blades the right way

*2328079* 2328079 English 11
round (observe correct direction of rotation). Use of saw blades of a size outside
the specified diameter range is prohibited!
▶Always wear working gloves when touching the saw blade. The saw blade is sharp
and can get hot.
▶Stay alert at all times while working. Monitor the progress of the sawing operation and
keep an eye on the cooling water system and the area surrounding the workplace. Do
not operate the machine if your full attention is not on the job.
2.5 Safety during transport
▶Transport only tracks of length up to max. 1.5 m on the transport trolley. The higher
center of gravity of tracks longer than 1.5 m would increase the risk of the transport
trolley tipping over.
▶Use the transport trolley only to transport the saw system and its specified accessories.
Do not use the trolley to transport other items or materials.
▶Before transporting, make sure that all removable items of equipment are securely
fastened to the transport trolley or locked in position.
▶Avoid lifting and carrying heavy objects. Use suitable lifting equipment and means of
transport and share heavy loads between several people as necessary.
▶Use the grips provided for transportation. Keep the grips dry, clean and free from oil
and grease.
▶Bear in mind that the transport trolley can topple. Stand the transport trolley only on a
solid, level surface.
▶Secure the saw system and its components to prevent inadvertent movement or falling
over during transportation.
▶Bear in mind that only tested and approved lifting gear correctly secured to the points
provided for the purpose may be used for crane-lifting the transport trolley.
▶Never loiter beneath a load suspended by a crane or lifting equipment.

The sound pressure and vibration values given in these instructions have been measured
in accordance with a standardized test and may be used to compare one power tool with
another.
Sound emissions in operation can vary up to 10 dB(A) from the stated measured values,
depending on the type of diamond saw blade used and the operating conditions. Adapt
ear protection and other noise-control measures to the specific operating conditions.
The noise pressure level can be reduced by approx. 10 dB(A) when noise-reducing
(silent) saw blades are used.

5 Planning
5.1 Cutting sequence
▶Make dividing cuts to adjust the maximum size and weight of the concrete blocks
to the prevailing conditions (i.e. the lifting capacity of the crane or the maximum
permissible floor loading capacity and size of doors).
A rational cutting sequence can be achieved by appropriate spacing of the track
supports.
