How to Use Nemo Drill Underwater?

Before you use the Nemo tool underwater, you should pressurize the tool. You can do it by removing the red cap from the pressure valve on the back of the hammer drill. Then Attach a pump, such as a hand pump supplied with the hammer drill, to the valve.

Before you use the tool underwater, make sure the tool is pressurized with its recommended values.

Depth in MetersDepth in feetPressure
Up to 5m16 feetMinimum 15 psi ( 1 Bar )
Up to 10m33 feetMinimum 29 psi ( 2 Bars )
Up to 20m66 feetMinimum 44 psi (3 Bars)
Up to 30m98 feetMinimum 58 psi (4 Bars)
Up to 40m131 feetMinimum 73 psi (5 Bars)
Up to 50m164 feetMaximum 87 psi (6 Bars)
Nemo Pressure Related to Depth of the Water

*Do not add more than 87psi (6 bars)

Why is Nemo Pressurize Essential?

Nemo’s regular drills do not need to be pressured. It is with suitable seals. By pressurizing the tool is increased the inner pressure, which is a match to the working area pressure. When the depth is high, the water pressure is also increased. When the tool inside pressure is increased, its seals will not break due to the water pressure.

Nemo Best Practise for Usage

  1. In order to maintain the tool and battery, we need to practice the best steps. The drill can be used under salty, chlorine, and drinking water. Make sure to rinse the tool in salty water after you use it.
  2. Do not exceed the recommended depth
  3. Pressurize the inside before using in-depth water
  4. Follow the battery charging guide for the problem
  5. Before inserting the battery into the hammer drill, check that the three O-rings on the battery are present and undamaged.
  6. If any of the O-rings is missing, water will leak inside, and it will cause serious damage and lifetime of the drill
