Temperatures
• The maximum surrounding temperature for which the
certification is valid is 40°C.
• 40°C is also the maximum allowed temperature of the
compressed air when it enters the product.

• If the product is installed in an equipment, the entire
equipment has to correspond to the guidelines 2014/34/
EU.
• Make sure that the compressed air fulfil our quality de-
mands (quality classes 2.4.3. and 3.4.4 respectively 3.5.4
acc. to ISO/DIS 8573-1:2010).
• Do not exceed maximum pressure of 6.3 bar, or as stated
on the product nameplate. Exceeding the operating pres-
sure can increase the surface temperature due to higher
rotating speed and the product can become an ignition
source.
Ex Classification
If the product is part of an assembly where the components
have different Ex classification, the component with the low-
est level of safety defines the Ex classification of the com-
plete assembly.
Explosion Prevention Guidelines
Cleanliness
• Make sure the product is kept clean from dust and dirt to
prevent increased bearing and surface temperature.
• If using a silencer: Make sure a silencer with a filtering
effect at the air outlet is installed to prevent any friction-
heated particles entering into the surrounding atmosphere.
Usage
• Make sure the product is earthed to the equipotential
bonding system of the workshop, for example through ac-
cessories such as hoses and air-pressure connections.
• It is the responsibility of the user to make sure that the
product and all possible accessories, such as wrenches
and air connections, conform to the national safety regu-
lations for equipment used in potentially explosive areas.
