Objective A1: Locate the hazardous areas of the machine
Warning
* Moving machine parts can cause injury.
* During this course the machine may be operated with covers
removed.
* Always remove system power prior to undertaking any work on
machine.
* Ensure you DO NOT push or press any buttons or operate the
machine until all personnel are clear of danger.
Personal Safety
Tick each safety item as it is demonstrated to you by your instructor:
Strong Magnet Warning (Machines with Linear Motors only)
The linear motors inside the machine contain*
strong permanent magnets.
These may interfere with pacemakers and metallic implants.*
These magnets could potentially erase data on credit cards,*
ID cards etc.
