of the head cover some parts are voltage-carrying. Contact may cause
serious damage! Work on voltage-carrying parts must be carried out by
service technicians approved by LEIBINGER.

 Upon contact the contents causes skin irritation. Protective equipment
 Read the safety data sheets and the personal protective equipment
The print head must be checked daily and cleaned in the event of recognizable dirt
through penetrating dust or ink. In this respect high release of solvent vapors should be
avoided through the economical use of Leibinger solvent (corresponding to the
Leibinger ink). This is achieved through applying the Leibinger solvent to fluff-free paper
with the spray bottle and wiping off the parts to be cleaned with this. Direct spraying off
of the print head with solvent should only be carried out with very major dirt and should
be limited to the front part of the print head. Following intensive cleaning the nozzle seal
must be lubricated with a commercially available oil (spindle and guide).
Oil must not get into the gutter (back absorption)! Solvent dropping down must be
collected using a solvent resistant metal vessel and disposed of properly.
This work must only be carried out by trained personnel or by Leibinger
service technicians!
