General Guidelines
The purpose of this Safety Inspection Guide is to help 
you identify possible unsafe conditions on machines 
that are being inspected for a Maintenance 
Agreement. Each machine has necessary functions 
items installed to provide the operators and service 
personnel with an acceptable level of safety. This 
guide lists only these items. Good judgment should 
be used to identify possible safety conditions not 
covered by this Safety Inspection Guide.
If any unsafe conditions are present, you must find 
out how serious the hazard is and if you can continue 
before you correct the hazard.
All current IBM Personal Computer service 
supplements outlining feature/model changes, along 
with the machine history, should be reviewed.
Check the following items:
•
Damaged, missing, or changed parts, especially in 
the area of the On/Off switch and the power 
supply.
•
Damaged, missing, or changed covers.
•
Possible safety exposure from any non-IBM 
attachments.
