OWNER PREVENTIVE MAINTENANCE PROCEDURES
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. Customer PMs should be conducted bi-monthly per OSHA Bakery Oven Inspection
Standard 29 CFR 1910.263(l)(9)(ii). 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 Hobart Bakery System service agency for any needed
repairs.
