The safety strap which is included with the analyzer should be checked for condition prior to each use. Most safety straps use Velcro and the Velcro is there for your safety. The strap is designed to separate to prevent injury should your cables become tangled in the rotating shaft or some other moving part of the machine.
Replace the straps if the Velcro becomes dirty or no longer holds. Never glue, bolt, staple, or otherwise permanently affix a strap to the analyzer, because this could prevent the strap from functioning correctly and result in serious injury to you or a coworker.
