Extraordinary Maintenance; Re-Start After Long Period Of Inactivity; How To Request After-Sales Assistance; Diagnostics - Zhermack CALIFORNIA 2 Mode D'emploi

Elimination and/or recycling of the used sands (and,
consequently, sandblasting process residues) must be carried
out in compliance with EC directives or according to the laws in
force in the country of use.
If the sandblaster is not used for a prolonged period it is recommended that
you disconnect the apparatus from the electrical power supply.
8.2 ROUTINE MAINTENANCE
Once the equipment has been cleaned (see paragraph 8.1), the operator
must check for worn, damaged or loose parts. If any such situations are
detected, contact the Authorised After-Sales Centre.
If any of the previously-described situations should occur, it is
prohibited to re-start the equipment before the problems have
been solved.
In particular, before moving away from the equipment, the operator
detecting problems of any nature must place a sign on the it indicating
that equipment maintenance is in progress and that use is prohibited
(EC-compliant signs can be purchased from the relevant suppliers). Routine
maintenance, cleaning and correct equipment use are essential factors in
guaranteeing long-lasting equipment performance and safety.
Equipment safety devices/guards must never be removed
except for repair and maintenance purposes.
Such items must be replaced as soon as the situation which
led to their removal no longer exists and in any case before the
equipment is used again.

EXTRAORDINARY MAINTENANCE

Extraordinary maintenance includes the repair of any accidental breakage
and the replacement of worn or malfunctioning parts.
All electrical and mechanical interventions must only be
performed by a Zhermack-authorised maintenance technician.
Any modification that alters equipment features from a safety
and risk-prevention point of view can only be carried out by the
Manufacturer who will then certify conformity of the equipment
with safety standards. Therefore any modification or
maintenance intervention not considered in this manual is to be
considered prohibited. Any modification, tampering or repair
performed by unauthorised staff along with the use of non-
original spare parts relieve the Manufacturer from any liability. If
the necessary maintenance interventions are not considered in
this Use and Maintenance Manual, contact the Authorised After-
Sales Centre.
8.4

RE-START AFTER LONG PERIOD OF INACTIVITY

If the equipment is re-started after a particularly long period of
inactivity, operate as indicated in Chapter 6 regarding commissioning.
If the equipment functions anomalously, act as described in Chapter
9 regarding "Diagnostics". if the problem should persist or is not
considered, contact the Authorised After-Sales Centre immediately.
