Good quality crimping is essential in ensuring the long term reliability of the wheelchair ’s electrical system. Poor quality crimps
may initially appear to be satisfactory but, over time, they may cause problems. It is recommended that crimp quality is
maintained by implementing the procedures detailed in IEC-60352-2 1990.
WARNING:
Defective or poor quality crimps may affect the warranty of the control system. Curtiss-Wright accepts no liability for losses
of any kind arising from failure to comply with this condition.
Hand tools for crimping and extraction are available from Greenstock. The references are as below.
