5.8 Starting
Before placing the coupling into service, check:
• The tightening torque of the hub screws.
• The correct alignment has been achieved.
• The correct distance between the hubs.
Working in hazardous zones, tightening of the screws must be made even more securely by using Loctite (medium strength).
The user must periodically check, depending on the type of use and the substances used:
• the state of wear and correct functioning of the coupling
• the presence of vibrations and/or noise: in this case, the user must identify the causes and contact the manufacturer
For use in zones classified for the presence of combustible dust, ensure regular cleaning in order to avoid the formation of dust layers;
for this purpose, use equipment suitable for the classification of the zone.
This operation must be performed with the elements tightly coupled and in the absence of electrical voltage.
Ensure routine maintenance, according to a frequency to be determined according to the operating conditions, environment and
temperature. Nevertheless, residual risks can be present during normal operation of the coupling, if:
• it is not subjected to the normal maintenance plans provided from the User and Maintenance Manual
• it is not used as provided in the design specifications
Different or additional uses not included in the technical specification are not permitted and SIT shall not be liable for any damage related
to unauthorised uses.
All maintenance operations must be carried out as indicated in the User and Maintenance Manuals: no modifications are permitted
without the written consent of SIT.
Unauthorised replacements or those using non-original parts invalidate the safety of TRASCO
®
couplings; all spare parts must be
obtained from SIT.
CAUTION!
All operations must be performed by trained and qualified
personnel; different or additional uses to those envisaged in
this User and Maintenance Manual are not permitted.
5.7 Internal manufacturing check
Before marking and placing on the market, TRASCO
®
transmission couplings have been subjected to the checks and inspections provided
for by the internal manufacturing system and by the company’s quality system.
SIT S.p.A. has in fact obtained Certification of the Quality Management System according to international UNI EN ISO 9001 standard.
CAUTION!
Replace the elastic spider with an equivalent one of the same size.
SIT S.p.A. does not accept any liability for incorrect replacements.
For information on correct assembly, please refer to this User and
Maintenance Manual.
