Figure 4-67. Hoses, Lines and Fittings
Check air hose and fittings listed below for leaks.
The 1/8 inch (3.18 mm) black hose between formulation tank and cab control panel pressure gage.
a. If hoses are frayed, cracked, or cut, replace them and go to Step 3e.
b. If fittings leak, tighten them and check the pressure gage again.
If pressure is 90-100 psi, the problem is solved.
If pressure is less than 90 psi, go to Step 3c.
If fittings are dented or bent, replace the hose and fitting and go to Step 3e.
d. If 1/8 inch (3.18 mm) hose is crimped or bent at a sharp angle, replace it and go to Step 3e.
