Page 43: Maintenance
Maintenance Maintenance Preventive maintenance has been reduced to a minimum by the careful design of reliable components and material. However, the following measures should be taken at regular intervals and in proportion to the hours of service. IMPORTANT! Make certain that all electrical power to the machine is shut off before removing top or rear panels.
Page 44: Trouble-Shooting
Trouble shooting The purpose of the trouble-shooting guide is to facilitate the location and correction of the most common machine problems. Before the top panel is removed, power to the machine must be switched off at the main source or at the separate circuit breaker. At each trouble-shooting attempt, the plug in connectors on the control panel should be moved in and out in order to eliminate improper contact due to faulty connection.
