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 or shorted wire may be at fault
where electrical components are concerned and not necessarily the suspected 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 making repairs.
WARNING: ALL SERVICE AND TROUBLESHOOTING SHOULD BE PERFORMED BY A
QUALIFIED PROFESSIONAL OR SERVICE AGENCY.
