the abrasive is too rich in investment
slags.

TECHNICAL REFERENCE REGULATIONS AND TEST PROCEDURES
The ORO sandblaster is mass-manufactured by DENTALFARM in compliance with
technical and safety rules in force, as provided for by the 2006/42 CEE Community
Directive on Machinery.
Careful inspection and full routine testing is carried out singularly on each machine which
is furtherly tested by an automatic test installation assuring compliance with the fixed
limits.
DEMOLITION AND WASTE DISPOSAL
According to International regulations, this unit has been classified as AEE
(electric and electronic device, whose correct operation depends on electric
currents and electromagnetic fields) and as a consequence, at the end of its
lifetime, it can not be treated as normal waste material but it must be disposed
separately, complying with the Directive 2002/96/CE
Stop up the end of the nozzle and operate the
valve; air flow will thus be inverted eliminating
any residuals from the piping; ev. replace the
abrasive.
Problem: INTERNAL LOSS OF AIR
Check: polyethylene pipes may not be perfectly
calibrated, try to cut a small piece from one end
and introduce it in the pipe-fitting; ev. replace.
Check plan of the sheet body, condition of the
joint and pressure of the closing dowel on the
window.
Check regulalry condition of the dry filter or of the
extraction system.
