air hose with a hose joint of shock resistant material.
In case universal twist couplings ( claw couplings) are used, the lock pins must be mounted.
Do not exceed the maximum air pressure as indicated on the tool.
Never carry the tool by the air hose.
On overhead work, use safety helmet.
Cut parts may eject, prevent exposure.
Due to the process, the work piece, inserted/mounted tool/accessory may get hot causing burning injuries: Be aware of this.
A high force on the tool may cause high reaction forces on the tool.
Only use air hoses that are designed for it and are resistant against the used air pressure.
Check that sparks and debris can not cause any hazard.
Check the abrasive product on damages after it dropped.
Always use "safety quick change couplers".
Never let the tool run free in the air: the accessory may come loose and become a projectile causing danger or injury

Do not wear any shawls jewelry etc that can be trapped or entangled causing injuries.​
​In case of power loss, release the trigger immediate.
​Make the possible countermeasures to minimize noise emission: if possible, use silence materials on the workpiece or walls around the
work station.
A risk assessment related to the noise emission at the work station on the work piece has to be made to determine the correct ear
protection according to health and safety regulation. ​
A risk assessment related to the vibration exposure to determine the maximum working hours per day for the operator. Vibration can
cause damage to blood vanes and nerves (white finger disease). Hold the tool with light but safe grip, higher grip force can increase
vibration effects.​
