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 mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

• Keep the 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.

• A void body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of elec-tric 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.

• D o not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
  D o 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. 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 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.

• Press properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewel-lery 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. D o 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 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.
• 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.

SAFETY WARNINGS COMMON FOR GRINDING OR ABRASIVE CUTTING-OFF OPERATIONS:

• 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.
• Use only diamond cut-off wheels for 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 cut­off 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.
• 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.
•  Threaded mounting of accessories must match the grinder spindle thread. For accessories mounted by flanges, the arbour hole of the accessory must fit the locating diameter of the flange. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
• D o not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an unda­maged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no­load speed for one minute. Damaged accessories will normally break apart during this test time.
• W ear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respira-tor must be capable of filtrating particles gene-rated 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. Frag-ments of workpiece or of a broken accessory 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 accessory.
• Never lay the power tool down until the acces­sory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
• D o 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 hou-sing and excessive accumulation of powdered metal may cause electrical hazards.
• D o not operate the power tool near flammable materials. Sparks could ignite these materials.
• D o not use accessories that require liquid cool­ants. Using water or other liquid coolants may result in electrocution or shock.

Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’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 start­up. 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.
• D o not position your body in the area where po­wer tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
• U se 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 cause loss of control or kickback.
• D o not attach a saw chain woodcarving blade 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 bin-ding 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 re­enter the cut. The wheel may bind, walk up or kickback if the power tool is restar-ted 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 kick-back.

ADDITIONAL SAFETY WARNINGS

• People below the age of 16 may not use the machine.
• The user or operator must be familiar with the content of this instruction manual.
• Before chasing in load­bearing walls, consult with the responsible structural engineer, archi­tect or site supervisor.
• Use the power tool only when included guard is installed. Guard must be securely fitted to power tool and adjusted to guarantee the best possible safety level, which means that cutting disc part facing operator must be shielded as much as pos­sible. The guard must protect the operator against splinters and accidental contact with cutting disc.
• Use only diamond cutting discs. Possibility of equipment installation in the power tool alone does not guarantee safe use.
• Use diamond cutting discs only for tasks they are designed for. For example, never grind with side surface of a cutting disc. Cutting discs are designed to remove material with disc edge. Applying side force may break disc of this type.
• Always use undamaged fixing flanges with size matching to cutting disc. Proper flanges sup-port cutting disc and reduce risk of breaking.
• Secure the work area, also behind openings and cut­outs. Unsecured work areas can endan-ger you and other people.
• Watch out for open and concealed electricity cables, as well as water and gas pipes. Use suitable detectors to find concealed utility pipes and/or cables, or contact a 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.
•  W henever power tool can hit hidden electric wi­res or its own power cord during operation, hold it only by insulated handle. When in contact with live wires all metal parts of the power tool are live too, this may cause electric shock of the operator.
• 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.
• A void dust accumulation in the workplace. Dusts can easily ignite.
• Ensure adequate ventilation in closed rooms. Risk due to dust and impaired vision.
• Ensure the workplace is properly ventilated. O bserve the relevant regulations in your country for the materials to be machined.
• Keep power cord away from rotating working tools. Loss of control over the power tool can lead to cutting or catching the power cord, also hand or whole arm can get into rotating work tool.
• Do not carry power tool when it is rotating. Accidental contact of rotating working tool with clothes may cause its catching and plunging of working tool into operator’s body.
• Do not start working before the power tool reaches its full rotary speed.
• D o not expose diamond dry­cutting discs to lateral pressure.
• Never use diamond dry­cutting discs for rough grinding.

Electrical safety

The wall chaser is designed to work with speci-al 3-in-1 discs. Only use discs approved by the manufacturer.

1. Hold the outer flange (7) using the supplied large spanner.

2. Remove the bolt (6) using the supplied small spanner.
   Note: the bolt has a left hand thread.

3. Remove the outer flange (7).

4.  Mount the disc (8) onto the spindle. Ensure the arrow on the housing correspond with the arrow on the disc (8).
   Note: the spindle does not protrude the hole of the disc (8).

5. Put the outer flange (7) into the hole of the disc. Rotate the outer flange (7) while pressing it, until it is fully tightened.

6. Tighten the bolt (6).

7. Use the large spanner to hold the outer flange (7). Now tighten the bolt (6), using the small spanner.

To remove the disc, follow the installation proce-dure in reverse sequence.

Dust extraction (Fig. A, F)
Provide good ventilation at the workplace. Wear dust protection.
The dust from certain materials such as such as particulate matter can be harmful to your health. Breathing in this dust can cause allergic reactions and/or cause respiratory illnesses for the user or people in the near vicinity. Therefore a dust extraction system that is suitable for the material must be used. To do so:
The dust extractor must be suitable for the material being worked.
When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a special dust extractor.
A vacuum cleaner hose (14) can be connected to the dust extraction port (12). When starting to work, first switch on the dust extraction system, e.g. industrial vacuum cleaner, next switch on the wall chaser. When the work is finished proceed inversely – switch off the wall chaser first, next the vacuum cleaner.
Avoid dust accumulation at the workplace. Dust can easily ignite.
The dust extraction system can be blocked by dust, chips or fragments of the workpiece. Thus, it must be cleaned regularly. To do so:

1. Disconnect the mains plug from the power supply.
2. Wait until the disc (8) has come to a complete stop.
3. Remove any blockage if necessary.

OPERATION

Adjusting the cutting depth (Fig. B, E)
Set the chase depth before starting to work and with the device switched off.

1. Loosen the lever (11) by moving it backwards. Adjust to the required cutting depth, as shown on figure E.
2. The depth can be read on the scale (13).
3. Tighten the lever (11) by moving it forwards.

Switching on and off (Fig. A)

• To switch on the machine, keep the lock-off but-ton (2) pressed and simultaneously press the on/off switch (1).
• To switch off the machine, release the on/off switch (1).

Making a cut (Fig. A, G)
The wall chaser is designed only for straight cuts. Making curved or round cuts is not allowed.
The tool is designed for dry cuts only.
Always hold the tool with two hands on the insulated handles.

1. Draw lines to define the direction in which to guide the discs.
2. Mount a vacuum cleaner to the dust outlet.
3. Set the cutting depth.
4. Position the rear roller (4) on the wall surface. Note that the disc should not yet touch the wall surface.
5. Switch the wall chaser on and wait until the discs reach full rotational speed.
6. Gradually lower the wall chaser, plunging the discs into the wall surface.
7. As soon as the front roller (9) rests on the wall surface, continue with the cut and move the wall chaser forward and away from you (in direction opposite to rotation of cutting disc).
8. Slowly move the machine along the pre-drawn lines, firmly pressing the wheels against the wall. Note: Do not apply too much pressure on the machine. Let the machine do the work. Applying excessive pressure may cause motor overhea-ting and damage of the cutting disc.
9.  To end the cut, switch off the machine and wait until the discs have stopped completely. After-wards remove the discs from the chase and put down the machine.

After switching the wall chaser off, do not force the braking of the rotating disc by pressing it against processed material.
Cutting discs heat up to high temperatures during operation – do not touch them with unprotected parts of your body before they cool down.

Note: When cutting very hard materials, cutting disc may be overheated and become damaged in consequence. Excessive sparks around the cutting disc indicate overheating. When it appears, stop cutting and cool down the disc by running it with full rotational speed with no load for 3–5 minu-tes. A decrease of cutting efficiency and constant excessive sparks around the cutting disc may indicate a blunt cutting disc.

MAINTENANCE

Before cleaning and maintenance, always switch off the machine and remove the mains plug from the mains.
Clean the machine casings regularly with a soft cloth, preferably after each use. Make sure that the ventilation openings are free of dust and dirt. Re- move very persistent dirt using a soft cloth moistened with soapsuds. Do not use any solvents such as gasoline, alcohol, ammonia, etc. Chemicals such as these will damage the synthetic components.
