1.2 Intended use
•The wall chaser (normative cut-off machine), in the following also referred to as device, in
conjunction with an approved industrial dust extractor, is intended to cut or slit primarily
mineral materials, e.g. concrete or masonry when firmly applied with the guide sled without
the use of water. Any other uses, and/or modifications to the appliance, are deemed to be
improper usage and may result in serious physical injury. Not for commercial applications.
1.3 General safety instructions for power tools
•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 mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1.3.1 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.
1.3.2 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.
1.3.3 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
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.

User’s Manual – AREBOS Wall Chaser

•Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
•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.
•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.
1.4 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 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.
•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. 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.
1.5 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.
1.6 Cut-off machine safety warnings
•The guard provided with the tool must be securely attached to the power tool and positioned for
maximum safety, so the least amount of wheel is exposed towards the operator. Position
yourself and bystanders away from the plane of the rotating wheel. The guard helps to protect
operator from broken wheel fragments and accidental contact with wheel.
•Only use diamond-tip cutting discs with your power tool. Just because an accessory can be
attached to your power tool, it does not assure safe operation.
•The rated speed of the accessory must be at least equal to the maximum speed marked on the
power tool. Accessories running faster than their rated speed can break and fly apart.
•Wheels must be used only for recommended applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
•Always use undamaged wheel flanges that are of correct diameter for your selected wheel.
Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
•Do not use worn down reinforced wheels from larger power tools. Wheels intended for a larger
power tool are not suitable for the higher speed of a smaller tool and may burst.
•The outside diameter and the thickness of your accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
•The arbour size of wheels and flanges must properly fit the spindle of the power tool. Wheels
and flanges with arbour holes that do not match the mounting hardware of the power tool will

User’s Manual – AREBOS Wall Chaser

run out of balance, vibrate excessively and may cause loss of control.
•Do not use damaged wheels. Before each use, inspect the wheels for chips and cracks. If power
tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting
and installing the wheel, position yourself and bystanders away from the plane of the rotating
wheel and run the power tool at maximum no load speed for one minute. Damaged wheels will
normally break apart during this test time.
•Wear personal protective equipment. Depending on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust mask, hearing protectors and shop apron capable of
stopping small abrasive or workpiece fragments. The eye protection must be cap-able of
stopping flying debris generated by various operations. The dust mask or respirator must be
capable of filtrating particles generated by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
•Keep bystanders a safe distance away from work area. Anyone entering the work area must
wear personal protective equipment. Fragments of workpiece or of a broken wheel may fly away
and cause injury beyond immediate area of operation.
•Hold the power tool by insulated gripping surfaces only, 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.
•Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into the spinning wheel.
•Never lay the power tool down until the accessory has come to a complete stop. The spinning
wheel may grab the surface and pull the power tool out of your control.
•Do not run the power tool while carrying it at your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the accessory into your body.
•Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal may cause electrical hazards.
•Do not operate the power tool near flammable materials. Sparks could ignite these materials.
•Do not use accessories that require liquid coolants. Using water or other liquid coolants may
result in electrocution or shock.
1.7 Further safety instructions for abrasive cutting-off operations
Kickback and related warnings
•Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging
causes rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to be
forced in the direction opposite of the wheel’s rotation at the point of the binding.
•For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into the surface of the material causing the wheel to
climb out or kick out. The wheel may either jump toward or away from the operator, depending
on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break
under these conditions. Kickback is the result of power tool misuse and / or incorrect operating
procedures or conditions and can be avoided by taking proper precautions as given below.
•Maintain a firm grip on the power tool and position your body and arm to allow you to resist
kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or
torque reaction during start-up. The operator can control torque reactions or kickback forces, if
proper precautions are taken.
•Never place your hand near the rotating accessory. Accessory may kickback over your hand.
•Do not position your body in line with the rotating wheel. Kickback will propel the tool in
direction opposite to the wheel’s movement at the point of snagging.
•Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and

User’s Manual – AREBOS Wall Chaser

cause loss of control or kickback.
•Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral
gap greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of
control.
•Do not “jam” the wheel or apply excessive pressure.Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or
binding of the wheel in the cut and the possibility of kickback or wheel breakage.
•When wheel is binding or when interrupting a cut for any reason, switch off the power tool
and hold the power tool motionless until the wheel comes to a complete stop. Never attempt
to remove the wheel from the cut while the wheel is in motion otherwise kickback may occur.
Investigate and take corrective action to eliminate the cause of wheel binding.
•Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted
in the workpiece.
•Support panels or any oversized workpiece to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under their own weight. Supports must be placed under
the workpiece near the line of cut and near the edge of the workpiece on both sides of the
wheel.
•Use extra caution when making a “pocket cut” into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
