2.2.6
Feed Limit Switches. The feed limit switches are
two-position switches controlled by the position of the
feed limit switch paddles. Each endgate has a switch
and paddle which controls automatic operation of the
auger/conveyor system on that side. When paving
material fills the area between the augers and endgates
and presses against the feed limit switch paddle, the
auger/conveyor system stops. When the material is
used up and releases the paddle, the auger/conveyor
system starts again. Raising the position of the paddle
by loosening the thumbscrew and hex nut will increase
the amount of paving material at the leading edge of the
screed. Lowering the position of the paddle will
decrease the amount of material at the leading edge of
the screed.
2.2.7
Extension Screed Height Adjustments. The
height adjustments move the extension screeds up or
down to keep the extension screed plates parallel with
the main screed plates. Turn the extension screed
height adjustment knob forward to raise extension
screed plate height. Turn the knob back to lower
extension screed plate height. The adjusted height of
the extension screeds is locked in place using the
extension screed height catch plates. To change height
on one end of an extension screed, pull the quick release
pin out of the shaft. Slide the two halves of the knob
apart. Turn the left or right half of the separated knob to
raise or lower an end of the extension screed.
