LUBRICATE PRESSURE REGULATOR O-RINGS:
To maintain consistent adequate pressure delivery to the cleaning tool, the o-rings on the stem of the MX3-

Unscrew the brass knob assembly from the piston retainer.
3.
Remove the spring plate and spring from the piston retainer.
4.
Unscrew the piston retainer from the regulator body.
5.
Hold the hex head of the spindle with a wrench while using a screw driver to turn the piston screw and
separate the spindle head & piston screw so they can be removed from the stem retainer.

Use a synthetic grease with Teflon such as Ultra-Slick or Super-Lube to lubricate the o-rings on the piston
and spindle assembly.
7.
Re-install the piston and spindle assembly into the retainer and tighten.

Apply thread sealant to the threads of the stem retainer and screw the retainer back into the regulator
body and tighten.
