TROUBLESHOOTING
IMPORTANT: YOU MUST DISCONNECT and LOCKOUT THE ELECTRIC SUPPLY

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 component(s) 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 ... and not necessarily the suspected component itself.
Electrical parts should always be checked for failure before being returned to the factory. The information
provided should not be misconstrued as a handbook for use by an untrained person making repairs.
IMPORTANT: When replacing blown fuses, the replacement must be of the exact rating as the
fuse being replaced. For information provided should not be misconstrued as a
handbook for use by an untrained person in making repairs.

QUALIFIED PROFESSIONAL or SERVICE AGENCY.
