SECTION VII
TROUBLESHOOTING
IMPORTANT: YOU MUST DISCONNECT and LOCKOUT THE ELECTRIC SUPPLY and
THE GAS SUPPLY or THE STEAM SUPPLY BEFORE ANY COVERS or
GUARDS ARE REMOVED FROM THE MACHINE TO ALLOW ACCESS
FOR CLEANING, ADJUSTING, INSTALLATION, or TESTING OF ANY
EQUIPMENT per OSHA (Occupational Safety and Health Administration)
STANDARDS.
The information provided will help isolate the most probable components associated with the difficulty described.
The experienced technician realizes, however, that a loose connection or broken/shorted wire may be at fault
where electrical components are concerned...not necessarily the suspect component itself. Electrical parts
should always be checked for failure before being returned to the factory.
IMPORTANT: When replacing blown fuses, the replacement must be of the exact rating as the fuse
being replaced. The information provided should not be misconstrued as a
handbook for use by an untrained person in making repairs.
WARNING: ALL SERVICE and TROUBLESHOOTING SHOULD BE PERFORMED BY A
QUALIFIED PROFESSIONAL or SERVICE AGENCY.
WARNING: WHILE MAKING REPAIRS, OBSERVE ALL SAFETY PRECAUTIONS
