Maintaining the Vacuum Pump
•
First oil change: After 25 hours of initial use.
•
Future oil changes: Every 60 hours, 3 months or if oil becomes discolored.
Remove the oil drain bolt -
Locate the oil fill
bolt on the side of the machine. Place an oil
catch cup under drain bolt. Using your 7/8”
socket wrench, remove the oil drain bolt. Oil will
immediately begin to flow out of the machine.
Capture oil -
When oil is completely drained,
replace the drain bolt. Dispose of old oil properly,
according to your local and state regulations.
Refill pump with new oil -
Follow the “How To:
Set Up - Adding Oil to the VP320” instructions
on page 6.
Prepare oil in the pump -
Run the vacuum process a few times. This will
warm up the oil, allowing it to drain freely and remove any contaminants.
NOTE: The VP320 vacuum pump requires periodic oil changes. Follow
this oil change schedule to ensure proper maintenance of your VP320.
IMPORTANT: Make sure the VP320 is turned OFF and unplugged
before adding oil. Do not plug in or use machine until oil has been
properly filled.
