TROUBLESHOOTING
IMPORTANT: YOU MUST DISCONNECT AND LOCKOUT THE ELECTRIC SUPPLY
AND THE GAS 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.
