Maintenance
Do not attempt any service on this oven before opening the main power disconnect
switch.
Checklist
Keep equipment clean. Gradual dirt accumulation retards airflow. A dirty
oven can result in unsatisfactory operation such as unbalanced temperature
in the work chamber, reduced heating capacity, reduced production,
overheated components, etc. Keep the walls, floor and ceiling of the oven
work chamber free of dirt and dust. Floating dust or accumulated dirt may
produce unsatisfactory work results. Keep all equipment accessible. Do
not permit other materials to be stored or piled against it.
Protect controls against excessive heat. This is particularly true of
controls, motors or other equipment containing electronic components.
Temperatures greater than 51.5°C (125°F) should be avoided.
Establish maintenance & checkup schedules. Do this promptly and
follow the schedules faithfully. Careful operation and maintenance will be
more than paid for in continuous, safe and economical operation.
Maintain equipment in good repair. Make repairs immediately. Delays
may be costly in added expense for labor and materials and in prolonged
shut down.
Practice safety. Make it a prime policy to know what you are doing before
you do it. Make CAUTION, PATIENCE, and GOOD JUDGMENT the safety
watchwords for the operation of your oven.
Lubrication. Fan motor bearings are permanently lubricated. All door
latches, hinges, door operating mechanisms, bearing or wear surfaces
should be lubricated to ensure easy operation.
