Cleaning the Bowl

The regulator is equipped with a filter that becomes filled with drainage (moisture and dust) over time. When a certain amount of drainage collects, it drains automatically from the drain hose, but dirt remains inside the bowl ().

In the following situations, remove the bowl from the regulator and clean the bowl.

  • When drainage remains in the bowl.
  • When the inside of the bowl is dirty.

WARNING

Be sure to bleed off the air pressure before removing the regulator bowl.

Failure to do so may result in a rupture or components flying off.

WARNING

Before removing or attaching the regulator and before performing maintenance, make sure that the bowl is securely attached.

If the bowl is not properly attached, it may come flying off when compressed air is supplied.

WARNING

Clean the regulator bowl using a neutral detergent. Never use solvents such as gasoline, alcohol, or thinner.

Using solvents may degrade the bowl and may result in a rupture.

IMPORTANT

Before tightening a screw that has a specified tightening torque, be sure to attach a sleeve. Check the marking on the sleeve () and use a sleeve that matches the tightening torque value.

Failure to attach a sleeve will cause a torque in excess of the permitted amount to be applied, which may damage parts and materials.
