Maintenance

After passing the service limit, the display will indicate the negative number of excess operating hours or
cycles.
VACUUM PUMP
To protect the vacuum pump, proper maintenance is important. Carry out the following tasks carefully:
•
Check the vents and clean as necessary before turning on the machine to assure proper cooling of the
pump.
• When the air filter is saturated with oil, an oil mist may be expelled; replacement of the filter is required.
• Use the cool-down/dehumidification feature. When turning off the machine and closing the cover ,
the pump continues to run for some time. Any moisture in the oil of the pump will evaporate during this
phase. This increases the longevity of the machine and minimizes the need for oil changes and pump
maintenance.
•
Check the oil level regularly and add as needed.
•
Change the oil when the service symbol appears on the display.
NOTE
To reset the service interval counters after the oil change: Start machine and while the display shows the
hours or cycles, press and hold the button.
