1) The Snap-On connector seems tight – Is this normal?

Yes. Inside the connector is a rubber ring which grips the tire valve when you pull down the lever. Its normal for the rubber to be tight at first, especially in cold weather when the rubber is harder. Over time the rubber will wear and the connector will become easier to push on.

2) The set pressure seems to be slightly out compared to my standalone pressure gauge?

The tire compressor will stop pumping at your set pressure at an accuracy of +/-1Psi. Standalone pressure gauges are accurate to ANSI B40.1 (2% accuracy), so there can be a slight difference between the two. We recommend that if you need highly accurate tire pressures, to check with a standalone gauge. Then adjust the set pressure slightly on the inflator to compensate.

3) The pump seems loud. Is this normal?

Unfortunately, all pneumatic pumps are relatively loud. However, our inflator has a higher-grade pump fitted, which is quieter than other similar inflators.

4) What is the maximum pressure I can pump up a tire?

100Psi is the maximum pressure of this type of pump. There are some other similar pumps on Amazon that state 150Psi, but this is only a marketing tactic and they will not be able to pump this high

5) Do I really have to have the vehicle engine running?

Although not essential, we do recommend having the vehicle engine running for the following reasons:

  1. The voltage will be higher in the 12V outlet, meaning the pump will run faster.
  2. A weak battery will not be drained by the pump.

6) Why should I always start the vehicle engine before connecting the inflator to the 12V socket?

Always start the vehicle engine and then connect the tire inflator to the 12V socket. This is because some vehicles can produce a voltage surge on start-up which could blow the fuse in the inflator

7) How do I replace the fuse?

The fuse is installed in the 12V connector. To replace it, unscrew the end cap from the connector. Ensure to fit a 15A glass fast blow fuse (6 x 30 mm)

8) How Often Should I check my tire pressure?

You can check your pressure as often as you want, but a minimum of once a month or before a long journey is a recommendation made by Michelin and other major tire manufacturers. Tire pressure changes with any relatively small fluctuations ambient in temperature. Therefore if you live in an area which sees large temperature swings, then it may be prudent to check your tires more regularly.

9) What pressure should my tires be set at?

Each vehicle and tire have their own ideal pressure which changes with the load that you are carrying.  The recommended pressure is usually found in the user manual of your vehicle, on a label (tire placard) on the door frame of your vehicle or on the inside of the flap covering the gas tank.
