Cleaning

Clean with a soft dam cloth After use, wipe the power plunger down with a soft damp cloth, removing any dirt or water from the power plunger.
 When wiping the power plunger down, check to make sure no dirt or water as affected any of the parts of the plunger, or possibly seeped inside.
Plunger submerged in bucked If you happen to accidentally drop your power plunger in the water, or if water accidentally covers the air chamber, a more thorough clean will be required.
Air chamber, pump, trigger The air chamber will need to be dried out.

This is done by unscrewing the air chamber and disconnecting from the trigger and pump section of the power plunger.

O ring, differential valve The rubber O ring and the differential valve will need to be dried and cleaned if the power plunger is dropped into unclean water.

Both need to be dry and clean for the seal to work correctly, as any grit or moisture will affect the power plunger’s ability to work well.

Silicone spray should be used to protect the seals Applying a liberal amount of silicone spray to the seals and the internal workings of the power plunger will prevent the seals from drying out and cracking. This will also ensure that the parts of the tool are working smoothly.
