WARNING

The vibration emission level given in this information sheet has been measured in accordance with a standardised 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 signifi cantly 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 signifi cantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep 

the hands warm, organisation of work patterns

WARNING! Read all safety warnings and all instructions

. 

Failure to follow the warnings and instructions may result in 

electric shock, fi re and/or serious injury. 

Save all warnings and instructions for future reference. 

ANGLE GRINDER SAFETY WARNINGS

Safety Warnings Common for Grinding, Sanding, Wire 

Brushing or Abrasive Cutting-Off Operations: 
a) This power tool is intended to function as a grinder, 

sander, wire brush, or cut-off tool.

Read all safety warnings, 

instructions, illustrations and specifi cations provided with 

this power tool. 

Failure to follow all instructions listed below may 

result in electric shock, fi re and/or serious injury.

b) Operations as polishing are not recommended to be 

performed with this power tool. 

Operations for which the power 

tool was not designed may create a hazard and cause personal 

injury.

c) Do not use accessories which are not specifi cally designed 

and recommended by the tool manufacturer.

 Just because the 

accessory can be attached to your power tool, it does not assure 

safe operation.

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 fl y 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 guarded or 

controlled.

f) Threaded mounting of accessories must match the grinder 

spindle thread. For accessories mounted by fl anges, the 

arbour hole of the accessory must fi t the locating diameter of 

the fl ange.

 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 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 no-load speed for one 

minute. 

Damaged accessories will normally break apart during 

this test time.

h) Wear personal protective equipment. Depending on 

application, use face shield, safety goggles or safety glasses. 

As appropriate, wear dust mask, hearing protectors, gloves 

and shop apron capable of stopping small abrasive or 

workpiece fragments.

 The eye protection must be capable of 

stopping fl ying debris generated by various operations. The dust 

mask or respirator must be capable of fi ltrating particles generated 

by your operation. Prolonged exposure to high intensity noise may 

cause hearing loss.

i) 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 accessory 

may fl y away and cause injury beyond immediate area of 

operation.

j) Hold the power tool by insulated gripping surfaces only,  

when performing an operation where the cutting accessory 

may contact hidden wiring. 

Cutting accessory contacting a "live" 

wire may make exposed metal parts of the power tool "live" and 

could 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.

l) 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.

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 

will draw the dust inside the housing and excessive accumulation 

of powdered metal may cause electrical hazards.

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 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.

a) Maintain a fi rm 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.

b) Never place your hand near the rotating accessory.

Accessory may kickback over your hand.

c) 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.

d) 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.

e) Do not attach a saw chain, woodcarving blade or toothed 

saw blade. 

Such blades create frequent kickback and loss of 

control.

Safety Warnings Specifi c for Grinding and Abrasive 

Cutting-Off Operations:
a) Use only wheel types that are recommended for your 

power tool and the specifi c guard designed for the selected 

wheel.

 Wheels for which the power tool was not designed cannot 

be adequately guarded and are unsafe.

b) The grinding surface of the centre depressed wheels must 

be mounted below the plane of the guard lip.

 An improperly 

mounted wheel that projects through the plane of the guard lip 

cannot be adequately protected.

c) The guard must be securely attached to the power tool and 

positioned for maximum safety, so the least amount of wheel 

is exposed towards the operator.

 The guard helps to protect 

operator from broken wheel fragments and accidental contact with 

wheel and sparks that could ignite clothing.

d) 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.

e) Always use undamaged wheel fl anges that are of correct 

size and shape for your selected wheel.

 Proper wheel fl anges 

support the wheel thus reducing the possibility of wheel breakage. 

Flanges for cut-off wheels may be different from grinding wheel 

fl anges.

f) Do not use worn down wheels from larger power tools.

Wheel intended for larger power tool is not suitable for the higher 

speed of a smaller tool and may burst.

Additional Safety Warnings Specifi c for Abrasive Cutting-Off 

Operations:
a) Do not “jam” the cut-off 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.

b) Do not position your body in line with and behind the 

rotating wheel.

 When the wheel, at the point of operation, is 

moving away from your body, the possible kickback may propel 

the spinning wheel and the power tool directly at you.

c) 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 cut-off 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.

d) 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.

e) 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.

f) 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.

Safety Warnings Specifi c for Sanding Operations:
a) Do not use excessively oversized sanding disc paper. 

Follow manufacturers recommendations, when selecting 

sanding paper.

 Larger sanding paper extending beyond the 

sanding pad presents a laceration hazard and may cause 

snagging, tearing of the disc or kickback.

Safety Warnings Specifi c for Wire Brushing Operations:
a) Be aware that wire bristles are thrown by the brush even 

during ordinary operation. Do not overstress the wires by 

applying excessive load to the brush.

 The wire bristles can 

easily penetrate light clothing and/or skin.

b) If the use of a guard is recommended for wire brushing, do 

not allow any interference of the wire wheel or brush with the 

guard. 

Wire wheel or brush may expand in diameter due to work 

load and centrifugal forces.
