To maintain consistent adequate pressure delivery to the cleaning tool, the piston seal of the MX3-500HE
pressure regulator must be lubricated regularly.

1.

Release pressure from system before proceeding.

2.

Remove Brass Knob from the regulator body.

3.

Remove the Spring and Spring Plate from the Regulator Body.

4.

Use needle nose pliers to pull the Piston from the Regulator Body.

5.

Examine Piston and Seal. Replace as needed.

6.

Use a synthetic grease with Teflon such as Ultra-Slick or Super-Lube
to lubricate the seal on the regulator piston.

7.

Place the piston back into the opening on the regulator body.

8.

Place the Spring Plate on top of the piston. (Concave side toward piston.)

9.

Place the spring back into the handle and thread the handle back
onto the regulator body.
