OWNER PREVENTIVE MAINTENANCE PROCEDURE
INTRODUCTION
This customer PM section includes procedures to inspect for proper operation and cleaning of components.
Owner Preventive Maintenance Procedures are written for gas ovens. They can also be used for electric
ovens by omitting the steps that refer to components found only on gas ovens. To maintain the safety and
performance of bakery ovens, a program of scheduled periodic maintenance must be implemented. It is
the sole responsibility of the user to establish, schedule, and enforce such a program. Although the service
interval will vary depending on the environment in which the equipment is operating, it is recommended
that PM be performed and all safety devices are checked at a minimum of 12-month intervals. Check with
the authority having local jurisdiction if there are specific maintenance requirements specified by local,
state, or national codes. A convenient PM Checklist is provided at the end of this section.
NOTE:
This PM procedure does not discuss repair or replacement of components. Upon completion of
the PM procedure, you will need to contact a qualified servicer for any needed repairs.
Tools Used for Inspection Procedure
• Standard set of hand tools
• Vacuum cleaner - shop vac
PREVENTIVE MAINTENANCE PROCEDURE
Disconnect the electrical power from the machine and follow lockout / tagout

Certain procedures in this section may require electrical test or measurements
while power is applied to the machine. Exercise extreme caution at all times. If test points are not
easily accessible, disconnect power and follow lockout/tagout procedures, attach test equipment,
and reapply power to test.
