Remove nozzles (2, fig. 2-7) from tool box and Install in spray bar (1) Adjust nozzles so that the angle
between slot and bar centerline is approximately 30 degrees. This is accomplished with nozzle wrench (3)
by turning the adjustment screw until the wrench touches adjacent nozzle.
Fold down the extension, then unlock bar turn-up lever and lower spray bar to operating position
Set spray bar height (3, fig. 2-8) by loosening locknut (1), then set adjusting screw (2) until the nozzles are
about 12 in. from road surface when tank is empty. Adjust both sides equally so that spray bar is level.
After adjustment tighten locknut (1). At this height, spray fans will properly overlap for triple lap coverage
Under heavy wind conditions it may be necessary to lower bar further.
Perform complete lubrication service (see LO 5-3895-371-12).
Make complete inspection of the distributor, looking for loose nuts and bolts or any damage that may have
occurred in transit Verify that all parts are securely mounted.
Check fluid level in hydraulic reservoir tank (9, fig. 2-2) and verify that fluid is above sight gage level (8).
If hydraulic oil becomes too hot, red light on control pedestal (3,fig.2-1 will go on. Fluid temperature should not
exceed 180 degrees. If light remains on for more than 60 seconds, discontinue pumping and check for
plugged bitumen lines and /or frozen bitumen pump. Report to Organizational Maintenance.
Do not operate pumps for long periods without bitumen material to supply lubrication.
