SAFETY INSTRUCTIONS FOR ABRASIVE 

CUTTING APPLIANCES

FURTHER SAFETY INSTRUCTIONS FOR 

ABRASIVE CUTTING APPLICATIONS

 

 

a) The upper guard, which is a part of the power tool, must be 

attached securely and set in a way that ensures maximum 

safety, i.e. the smallest possible amount of the grinding tool is 

exposed to the operator. Ensure that you and anyone else in 

the vicinity remain outside of the range of the rotating 

grinding disc. The upper guard is designed to protect the 

operator from fragments and accidental contact with the 

grinding tool.

b) Use only diamond-coated cutting discs for your power tool. 

Just because you can attach the accessories to your power 

tool, does not ensure they are safe to use.

c) The maximum speed of the accessory tool used must be at 

least as high as the maximum speed specified for the power 

tool. Accessories which rotate faster than the maximum 

permissible rate can break and throw pieces into the air.

d) Grinding tools should on!/ be used for the recommended 

applications. For example: Never grind with the side surface 

of a citing disc. Cutting discs are designed to remove material 

with the edge of the disc. Any lateral application of force on 

these grinding tools can lead to breakage.

e) Always use an undamaged clamping flange of the correct 

size and shape for the selected grinding disc. Suitable 

Ranges support the grinding disc and reduce the risk of disc 

breakage.

 f)  Do not use worn grinding discs from larger power tools. 

Grinding discs for larger power tools are not designed for the 

higher rotational speeds of smaller power tools and can 

break.

g) The external diameter and thickness of the accessory tool 

used must comply with the dimensions of your power tool. 

Incorrectly dimensioned accessory tools cannot be 

sufficiently shielded or controlled.

h) Grinding discs and flanges must fit precisely onto the grinding 

spindle of your power tool. Accessory tools which do not fit 

precisely on the grinding spindle of the power tool will rotate 

unevenly, vibrate severely and can lead to a loss of control.

i)  Do not use damaged grinding discs. Check the grinding discs 

before each use for chips and cracks. If the power tool or 

grinding disc is dropped, check to see if it either are dam> 

aged, or use an undamaged grinding disc. After checking and 

inserting the grinding disc, ensure that you and any other 

people in the vicinity remain outside of the range of the 

rotating grinding disc, and allow the tool to rotate at maximum 

speed for one minute. Damaged grinding discs usually break 

during this test period.

j)  Wear personal protective equipment. Depending on the 

application, ensure that you use full face protection, eye 

protection or goggles. If required, use a dust mask, ear 

protectors, protective gloves or special apron particles. Eyes 

should be protected from flying debris that may be generated 

during certain applications. Dust or filter masks must filter any 

dust created by ^he application. If you are exposed to loud 

noise for any length of time, you can suffer a hearing loss.

k) Ensure that other people remain at a safe distance to your 

workspace. Anyone who enters the workspace must wear 

personal protective equipment. Fragments of the workpiece 

or broken accessory tools can fly off and cause injury -even 

outside the immediate working area.

l) Hold power tool by the insulated gripping surfaces when 

performing an operation where the accessory tool may 

contact hidden wiring or its own cord. Contact with a "live" 

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

and could give the operator an electric shock.

m) Keep the power cord away from any Totaling accessories. If 

you lose control of the appliance, the cord may get cut or 

caught and your hand or arm could get caught in the rotating 

accessory tool.

n) Never put the power tool down until the accessory tool has 

com» to a complete standstill. The rotating accessory tool 

could come into contact with 

e surface and cause you to 

lose control of the power tool.

o) Do not leave the power fool running while carrying it. 

Accidental contact between your clothing and the rotating 

accessory tool could cause your clothing to get caught and 

the accessory tool to penetrate a part of your body.

p) Clean the ventilation slits of your power fool regularly. The 

engine fan draws dust into the housing and a strong 

accumulation of metal dust  can cause electrical hazards.

q) Do not use the power tool in the vicinity of flammable 

materials. Sparks can ignite such materials.

r) Do not use any accessory tools which require liquid coolant. 

The use of water or other liquid coolants may lead to electric 

shock.

Kickback and corresponding safety instructions 

Kickback - causes and corresponding safety instructions

•   Kickback is a sudden reaction caused when o rotating 

grinding disc catches or jams. Catching or jamming causes 

the rotating accessory tool to stop abruptly. If this happens, 

on uncontrolled power tool turns rapidly against the direction 

of rotation of the accessory tool caught in the blockage.

•   If for example, a grinding disc catches or jams, the edge of 

the grinding disc that is projecting into the workpiece can get 

caught and break off the grinding disc or cause a kickback. 

The grinding disc can then fly in the direction of the operator 

or away from him, depending on the direction of rotation of 

the disc at the blockage. This can also break grinding discs.

a) Hold the power tool firmly in both hands and position your 

arms so they can absorb the force of a kickback. Always use 

the auxiliary handle, if available, so you have the maximum 

control over the kickback force or reaction torques at full 

speed. By taking adequate precautions, the operator con stay 

in control of the kickback and reaction torques.

b) Never hold your hand close to a rotating accessory tool. The 

accessory tool could hit your hand in the case of a kickback.

c) Avoid the area in front of and behind the rotating cutting disc. 

The kickback will force the power tool in the opposite 

direction to the direction of rotation of the grinding disc at the 

blockage.

d) Take special care when working around corners, sharp 

edges, etc. Avoid allowing the accessory tool to bounce back 

from the workpiece or jam. The rotating accessory tool it 

more likely to jam in corners or sharp edges or if it bounces. 

This can cause a loss of control or kickback.

A kickback is caused by incorrect use or misuse of the power 

tool. This can be avoided by taking proper precautions as given 

below
