OWNER PREVENTIVE MAINTENANCE PROCEDURE
INTRODUCTION
This customer preventive maintenance (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 Preventive Maintenance 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
specic maintenance requirements specied 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 qualied servicer for any needed repairs.
