Maintenance
Do not attempt any service on this oven before
opening the main power disconnect switch.
Checklist
Do not allow flammable solvents, combustibles, or other organic material to
accumulate in Class A ovens, as this could lead to fire or explosion, particularly if
the maximum solvent rating of the oven is exceeded.
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 50.5°C (122°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.
WARNING:
Disconnect the main power switch
or power cord before attempting
any repair or adjustment.
