Renfert Vario basic Mode D'emploi page 16

• Always wear appropriate eye protection when
operating the unit! Failure to wear eye protec-
tion can result in eye injuries due to airborne
particles.
• Never direct the nozzles towards your eyes or
uncovered areas of skin!
• Never work with the viewing pane open!
• Regularly inspect all connecting lines and hos-
es (e.g., power cord and compressed air hoses)
for damage (e.g., kinks, cracks, porosity).
• Units with damaged connecting lines or hoses,
or those which exhibit other defects may not be
used.
• Always disconnect the unit from the com-
pressed air supply prior to performing any
maintenance tasks.
• Always disconnect the unit from the mains
power supply prior to performing any work on
electrical components.
• Do not activate the foot switch when only the
compressed air inlet hose is connected. The
unconnected hose can whip about, resulting in
a significant risk of injury.
• It is the responsibility of the operator that na-
tional regulations during operation and regard-
ing a repeated safety inspection of electrical
equipment are complied with. For Germany
these are the regulation 3 by DGUV (German
Statutory Accident Insurance) in relation with
VDE (Association for Electrical & Electronic
Technology) 0701-0702.
• Only spare parts and accessories supplied or
authorized by Renfert GmbH may be used with
this product. If other spare parts or accessories
are used, this could have a detrimental effect
on the safety of the device, increase the risk of
serious injury and lead to damage to the envi-
ronment or the device itself.
When using micro sandblasting tanks:
• Check the tank cover for a secure seat prior
to starting operation. Tank covers that are not
securely closed can explosively open. Ejected
parts and abrasive represent a significant risk
of injury.
• Always wear safety glasses when working with
the tank (filling, cleaning, maintenance).
• Abrasive residue on the seal will result in leaks
and premature seal wear. Always clean the
threads and seal after filling and handtighten
the cover.
• Solvents and tensides can result in the for-
mation of microscopic cracks in the plastic
(explosion hazard!). Use only a clean, dry cloth
to wipe the tank out and off. Never write on the
tanks or place adhesive labels on them.
• Regularly inspect the tanks and tank covers for
damage and immediately replace any suspect
components.
