 Antistatic plastics are provided with conductive fillers to prevent
the build-up of static charge. This also reduces the insulating
properties of the plastic.
Do not work on electrically live parts.
 Always wear eye protection when working with desoldering
applications.
 Please be sure to read and follow the operating instructions for

plated suction nozzles with solder in order to remove storage-
related oxide film or impurities from the suction nozzles.
 Make sure that the suction nozzles are thoroughly wetted during
intervals between desoldering work and prior to storage of the
device.
 Do not use aggressive fluxing agents.
 Always make sure that the suction nozzles are seated correctly.
 Select the lowest possible working temperature.
 Select the largest possible suction nozzle shape for the
application. It should be about the same size as the soldering
