SAFETY
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.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable liquids, gases or dust.
Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) 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.
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 influence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in serious personal injury.

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 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.
5) 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.
SPECIAL SAFETY INSTRUCTIONS
General safety instructions for grinding: Use
a) This power tool is designed for surface grinding. Refer to all safety warnings, instructions, illustrations and specifications provided with this power tool.
Failure to follow all the instructions may result in electric shock, fi re and/or serious injury.
b) This power tool is not suitable for routing, polishing, sanding, working with roughing discs, wire brushes, parting grinder discs or fl ap discs.
Using the power tool for tasks for which it was not designed may create a hazard and cause personal injury.
c) Do not use accessories that are not specifically designed and recommended by the tool manufacturer.
Just because an accessory can be attached to your power tool does not mean safe operation is guaranteed.
d) 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.
e) 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 protected or controlled.
f) 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.
g) Do not use a damaged accessory. Before use, always check accessories for splinters or cracks and check grinding wheels for cracks or signs of severe wear and tear. If a 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 no-load speed for one minute.
Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Depending on the application, use a face shield, safety goggles or safety glasses. As appropriate, wear a 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 respirator must be capable of filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
i) Keep bystanders a safe distance away from your work area. Anyone entering the work area must wear personal protective equipment.
Fragments of a workpiece or broken accessory may fly into the air and cause injury beyond the immediate area of operation.
j) Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord.
A cutting accessory that comes in contact with a "live" wire may render exposed metal parts of the power tool "live" and give the operator an electric shock.
k) 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.
I) Never lay the power tool down until the accessory has come to a complete stop.
The spinning accessory may catch the surface and pull the power tool out of your control.
m) 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.
n) Regularly clean the power tool's air vents.
The motor's fan draws dust into the housing.
o) Do not operate the power tool near fl ammable materials.
Sparks could ignite these materials.
p) Do 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 the sudden response to an accessory pinching or jamming while rotating. Pinching or jamming causes the rotating accessory to stop abruptly, which in turn forces the uncontrolled power tool in the direction against the accessory's rotation at the point of jamming.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions. It can be avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use the auxiliary handle 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.
b) Never place your hand near the rotating accessory.
The accessory may kickback over your hand.
c) Do not allow your body to enter the area where the power tool would move if kickback occurs.
Kickback will propel the power tool in the opposite direction of the accessory's movement at the point of jamming.
d) Use special care when working around corners, sharp edges etc. You must prevent accessories from bouncing off the power tool and becoming jammed.
A rotating accessory tends to jam around corners and sharp edges and also if bouncing occurs, thus causing loss of control or kickback.
e) Do not attach a saw chain woodcarving blade or toothed saw blade.
Such blades create frequent kickback and loss of control.
SAFETY WARNINGS SPECIFIC FOR GRINDING WITH DIAMOND CUP WHEELS
a) Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel.
Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.
b) The safety guard must be securely attached to the power tool. Always direct the power tool so that the wheel is not openly exposed to the operator.
The guard helps to protect the operator from broken fragments, accidental contact with the wheel and sparks that could ignite clothing.
c) Wheels must be used only for applications.
d) Always use undamaged wheel fl anges that are the correct size and shape for your selected accessories.
The correct fl anges support the accessories.
ADDITIONAL SAFETY INSTRUCTIONS
WARNING – Always wear protective goggles.
Wear a suitable dust protection mask.
Always operate with two hands.
Observe the specifications of the accessory manufacturer! Protect the accessories from grease and physical impact.
Accessories must be stored and handled with care in accordance with the manufacturer's instructions.
The workpiece must be seated firmly and be secured against slipping, e.g. using clamps. Large workpieces must be supported adequately.
If accessories with threaded inserts are used, the end of the spindle may not touch the base of the hole on the grinding tool. Make sure that the thread in the accessory is long enough to accommodate the full length of the spindle.
The thread in the accessory must match the thread on the spindle. See page 7 SPECIFICATIONS for more information on the spindle length and thread.
Impurities that manage to enter the machine may block the switching
mechanism. This is why, when the machine is running, it is necessary to blow compressed air through the rear ventilation slots of the machine regularly, frequently and thoroughly. The machine must be held firmly in this case.
Additional Warnings:
Observe the relevant guidelines for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal).
Collect the generated particles at the source, avoid deposits in the surrounding area.
Use suitable accessories for special work (See page 11 ACCESSORIES), thus less particles enter the environment in an uncontrolled manner.
Use a suitable extraction unit.
r Reduce dust exposure with the following measures:
- For efficient dust collection, use a suitable metabo HPT (L-class and over) vacuum cleaner together with this power tool.
- Do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits
– Use an extraction unit and/or air purifiers - Maintain good ventilation of the workplace and keep clean using a vacuum cleaner Sweeping or blowing will stir up dust
- Vacuum or wash your protective clothing Do not blow, beat or brush.
