NOTE

When fluid regulating valve reaches cut-out pressure, there will be an audible "pop."

Start and run engine at idle until fluid regulating valve reaches cut-out

pressure.

Read pressure on dual brake gage. Reading must be approximately

106 psi.

� If reading is not approximately 106 psi, turn fluid regulating

valve adjusting screw (1) 1/4-turn to right to increase pressure,

or 1/4-turn to left to decrease pressure. Relieve air pressure

(page 2-23) from air tanks to approximately 80 psi and repeat

steps a and b until cut-out pressure is approximately 106 psi.

If correct cut-out pressure cannot be attained, replace fluid

regulating valve (page 4-306).
