Hold 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 shock the operator.

Position the cord clear of the spinning accessory.

 If you 

lose control of the power tool, 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.

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 accu-

mulation of powdered metal may cause electrical haz-

ards.

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.

Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged 

rotating wheel, backing pad, brush or any other acces-

sory. 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 mate-

rial 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 incor-

rect 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.

 Acces-

sory may kickback over your hand.

Do 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.

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 cause loss of control or kickback.

Do not attach a saw chain woodcarving blade or toothed 

saw blade.

 Such blades create frequent kickback and loss 

of control over the power tool.

Additional safety instructions for grinding and 

cutting off operations

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 can-

not be adequately guarded and are unsafe.

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 

size and shape for your selected wheel.

 Proper wheel 

flanges support the wheel thus reducing the possibility of 

wheel breakage. Flanges for cut-off wheels may be differ-

ent from grinding wheel flanges.

Do not use worn down wheels from larger power tools.

Wheels intended for larger power tools are not suitable 

for the higher speed of a smaller tool and may burst.

Additional safety warnings

Use elastic spacers/liners when these are provided with the 

grinding/sanding accessory.

Make sure that the application tools are mounted in accord-

ance with the manufacturers instructions. The mounted 

application tools must be able to rotate freely.

 Incorrectly 

mounted application tools can become loose during 

operation and be thrown from the machine.

Handle accessories carefully and store them according to 

the manufacturer’s instructions.

 Damaged accessories can 

form cracks and break off during operation.

When using application tools with a threaded insert, take 

care that the thread in the application tool is long enough 

to hold the spindle length of the power tool. The thread in 

the application tool must match the thread on the spindle.

Incorrectly mounted application tools can loosen during 

operation and cause injuries.

Beware of any concealed electric cables, gas or water con-

duits;

 check the working area with a metal detector, for 

example, before commencing work.

Use a stationary extraction system, blow out ventilation 

slots frequently and connect a residual current device 

(RCD) on the line side.

 When working metal under 

extreme operating conditions, it is possible for conduc-

tive dust to settle in the interior of the power tool. The 

total insulation of the power tool can be impaired.

Do not rivet or screw any name-plates or signs onto the 

power tool. 

If the insulation is damaged, protection against 

an electric shock will be ineffective. Adhesive labels are 

recommended.

Before putting into operation, check the mains connection 

and the mains plug for damage.

This machine is also intended to be powered by a.c. gen-

erators with sufficient power output that correspond 

with ISO 8528, design class G2. Compliance with this 

Standard in particular is not given when the so-called dis-

tortion factor exceeds 10%. When in doubt, inform 

yourself about the generator in use.

Hand/arm vibrations

The vibration emission level given in this information 

sheet has been measured in accordance with a standard-

ised test given in EN 60745 and may be used to compare 

one tool with another. It may be used for a preliminary 

assessment of exposure.

The declared vibration emission level represents the 

main applications of the tool. However if the tool is used 

for different applications, with different accessories or 

poorly maintained, the vibration emission may differ. 

This may significantly increase the exposure level over 

the total working period.

An estimation of the level of exposure to vibration 

should also take into account the times when the tool is 

switched off or when it is running but not actually doing 

the job. This may significantly reduce the exposure level 

over the total working period.

Identify additional safety measures to protect the opera-

tor from the effects of vibration such as: maintain the tool 

and the accessories, keep the hands warm, organisation 

of work patterns.

The vibrational emission values are given for dry grinding of 

metal with grinding wheels. Other applications, such as belt 

sanding, can lead to other vibrational emission values.

Handling hazardous dusts

For work procedures with this power tool where mate-

rial is removed, dusts develop that can be hazardous to 

one’s health.

Contact with or inhaling some dust types, e. g. asbestos 

and asbestos-containing materials, lead-containing coat-

ings, metal, some wood types, minerals, silicate particles 

from materials containing stone, paint solvents, wood 

preservatives, and antifouling paints for vessels, can trig-

ger allergic reactions to the operator or bystanders and/

or lead to respiratory infections, cancer, birth defects or 

other reproductive harm. The risk from inhaling dusts 

depends on the exposition. Use dust extraction matched 

appropriately for the developing dust, as well as personal 

protective equipment and provide for good ventilation of 

the workplace. Leave the processing of asbestos-contain-

ing materials to specialists.

Wood and light-metal dust, hot mixtures of sanding dust 

and chemical materials can self-ignite under unfavourable 

conditions or cause an explosion. Avoid sparking in the 

direction of the dust collector as well as overheating of 

the power tool and the materials being sanded, empty 

the dust collector/container in time, observe the material 

manufacturer’s working instructions, as well as the rele-

vant regulations in your country for the materials being 

worked.

Operating instructions.

Take care that the inner flange is mounted firmly on the 

output spindle and that the centering sleeve is mounted.

Make sure to check that the grinding accessory is wider 

than the height of the centering sleeve. Pay attention that 

the grinding accessory is properly centred between the 

inner flange and the threaded flange.

Using the same pressure, move the power tool back-

wards and forwards across the surface of the work piece 

to prevent it from becoming too hot.

Motor protection switch MShy664-1 (see page 6).

If given, the motor protection switch switches off the 

power tool in case of overload. After approx. 30 seconds 

upon actuation, the electronic system can be reset via 

button (a).

Do not actuate button (a) until after having released the 

power tool’s switch.

Repair and customer service.

When working metal under extreme operat-

ing conditions, it is possible for conductive
