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 motor power switch is turned OFF (right).
Running the pump for longer than 3 minutes without oil will damage
the pump and void the warranty.
4. Plug into power to activate the oil backlight.
5. Ensure your old empty oil bottle is located under the oil drain.
6. Open the oil drain valve clockwise (vertical) to empty the oil
reservoir of old oil.
7. Close the valve counter clockwise (horizontal).
8. Remove and cap the old oil for disposal.
ADDING FRESH OIL
9. Ensure the drain valve is closed (horizontal).
10. Unscrew the pump’s oil fill cap 1/4 turn counter clockwise.
11. Open a new 8 ounce bottle of Fieldpiece Vacuum Pump Oil (OIL8X3).
Put the bottle cap on the side of the bottle (CAP STORAGE).
12. Pour the entire 8 ounce bottle of fresh oil into the oil port and
ensure the oil level is between the MIN and MAX lines indicated on
the window bezel. Replace oil fill cap.
13. Place the empty bottle under the drain valve so it’s ready to gather
used oil during the next oil change.
14. 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 brass 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.
