TESTING INSTRUCTIONS
Thetestingprocessofthesafetybrakeconsistsof:
1. Anaccuratecheckofaperfectinstallation,bymakingsurethatallthefastening
screwsofthebaseandofthesafetybrakeareprovidedwithsuitableself-locking
washersandperfectlytightened.Makealsosurethatthesafetybrakehasnotbeen
undulyopened.
2. Acheckoftheelectricalcontinuityattheextremityofthemicro-switchthread.
