TM 5-3895-373-102.1.2SwitchPanel.The switch panel provides thefollowing control features to the operator.1.SCREED LIFT switchIn the up, LIFT position, the screed moves up.In the down, FLOAT position, the screed movesdown. The center, HOLD position, is the screedhold position.2.HORN switchOperates the paving machine horn. Power tothe paving machine is not required to operatethe horn.3.EMERGENCY STOP switchWhen pushed in, this switch cuts off all power tothe paving machine, except to the horn and worklights, and stops the engine. After the switch ispushed in, it must be pulled out before theengine can be restarted and paving machinefunctions operated.4.FLOW GATE switchesControl up and down movement of the flowgates, which control the amount of materialreaching the augers. In the up, OPEN position,the flow gates open, and in the down, CLOSEposition, the flow gates close. In the center,OFF position, the flow gates remain in position.5.AUGER/CONVEYOR switchesSelect between center OFF position, down"MAN", and up "AUTO" for control of theauger/conveyor systems. In the up, "AUTO"position, the auger/conveyor systems areautomatically controlled by the position of thefeed limit switch. In the down, "MAN" position,auger/conveyor system operatesregardless of the position of the feed limit switch.In either position, the feeder control switch onthe screed control panel must be in the ONposition.6.HOPPER WING switchesIn the up, RAISE position, the hopper wingsclose. In the down, LOWER position, the hopperwings open.CAUTIONUse extreme caution when retractingextension screed when auger andfender extensions or bolt-on screedextensions are installed. Damage toextension screed can occur.7.EXTENSION SCREED CONTROL switchesTwo switches control the extension andretraction of the extension screeds. Moving theleft switch to the left and right extends andretracts the left extension screed, respectively.Moving the right switch to the right and leftextends and retracts the right extension screed,respectively.8.SCREED VIBRATOR switchSelect between center OFF position, down"MAN" position, and up "AUTO" position, forcontrol of the screed vibrators.
