Safe handling of WAGNER spray units
The maximum surface temperature of the pump can be reached if it runs dry.
œ Ensure that the pump is filled with sufficient working or cleaning medium.
Mechanical sparks can form if the unit comes into contact with metal.
In an explosive atmosphere:
œ Do not knock or push the unit against steel or rusty iron.
œ Do not drop the unit.
œ Use only tools that are made of a permitted material.
Ignition temperature of the pumped material
œ
Check that the ignition temperature of the pumped material is higher than
the max. allowable surface temperature.
Medium supporting atomizing
œ
To atomize the material, use only weakly oxidizing gases, e.g. air.
