MAINTENANCE

WARNING

To reduce the risk of serious bodily injury, including

splashing in the eyes or on the skin, or injury from

moving parts, ALWAYS shut off the air supply and

relieve all air and fluid pressure in the system be-

fore removing or servicing the air regulator.

The regulator does not have to be removed from the air

line to clean it. Remove the two No. 10–32 screws on the

bottom of the regulator, then pull out the inner valve

assembly.

Wash the inner valve assembly with solvent. Be careful

not to damage the diaphragm and valve facings.

CAUTION

Do not use acetone, carbon tetrachloride, trichlo-

rethylene or similar solvents to clean the regula-

tor. These solvents could damage regulator

parts.

Be sure the spring housing vent hole is not clogged. Keep

the vent hole clear as a slight flow of air through this hole

is necessary for the regulator to operate properly.

Lubricate the adjusting screw with petroleum jelly.
