Frequently Asked Questions
Can the oil gun be used for food oil?
The oil gun material is not food grade, it’s not recommended for dispensing food oil.
How do I replace the battery and what type is needed?
The counter is powered by 2pcs of AA batteries. When the power is low, you can change the batteries by opening the back bolts.
Why does oil output decrease after long time use?
There is a filter net in the inlet port. You can disconnect the oil gun from the hose, check if the filter net is clogged, remove it, and clean it.
What measurement units are available on the digital meter?
The meter supports 4 types of units: Liters (L), Pints (PT), Quarts (QT), and Gallons (GAL), which can be adjusted according to your needs.
Can this oil gun be used with electric pumps?
Yes, it can be connected to both pneumatic and electric pumps to accurately display the refueling quantity during the process.
What is the difference between the Rigid and Flexible output models?
Rigid output (e.g., 37713X-A) provides a fixed metal spout, while Flexible output (e.g., 37713X-C) uses a flexible hose spout for easier access to difficult filling points.
