Maintenance

Repairs are to be performed only by authorized dealers. Before connecting the
reference device and the test specimen, the seals at both connections must be
checked for proper fit and wear and tear and replaced if necessary. A maintenance kit
consisting of O rings and seals is available as an accessory. The manual test pump
may not be dirty and in particular may not come into contact with damp, wet, or
aggressive media.
