Oil Change Procedure
Changing oil is easy and visible. Start each job
with fresh oil. Change as needed during the job.
DRAINING OLD OIL
1. For extended pump life, drain the oil immediatly after the job
instead of waiting until the beginning of the next job.
2. Ensure the pump oil inside is warm enough, >75°F (>24°C), for
proper drainage. Run the pump for 10 minutes if ambient temp is
low.
3. Ensure the VP55/VP85 motor power switch is turned OFF (down).
Running the pump for longer than 3 minutes without oil will damage
the pump and void the warranty.
4. Plug in VP55/VP85 to activate the oil backlight.
5. Pull open the oil bottle access door.
6. Ensure your old empty oil bottle is located under the oil reservoir.
7. Open the oil drain valve clockwise (vertical) to empty the oil
reservoir of old oil.
8. Close the valve counter clockwise (horizontal).
9. Remove and cap the old oil for disposal.
ADDING FRESH OIL
10. Ensure the drain valve is closed (horizontal).
11. Unscrew the pump’s OIL FILL cap 1/4 turn counter clockwise.
12. Open a new 8 ounce bottle of Fieldpiece Vacuum Pump Oil (OIL8X3).
Put the bottle cap on the side of the bottle (CAP STORAGE).
13. Pour the entire 8 ounce bottle of fresh oil into the OIL port. The oil
level should land within the FILL ZONE. Replace OIL FILL cap.
14. Place the empty bottle under the drain valve so it’s ready to gather
oil at the next oil change.
Push down on the spring loaded platform to locate the bottle
underneath the drain.
15. Close the oil access door.
16. Your vacuum pump is now ready to operate.
Dynamic Vacuum Measurement
During the pull down, the system’s vacuum
level drops faster at the front of the system, near
the vacuum pump.
To ensure that your full system achieves the
target micron level, place the vacuum gauge
as far to the back of the system, away from the
pump, as possible.
Remote Exhaust
Unscrew the EXHAUST cap and connect an
obstruction-free garden hose if you need to
exhaust oil mist and vapor remotely to the
outside of a building structure.
