III. DRY RUN CHECK OUT
A. Operation of Distributor Controls
First with bar turned up and ends latched in place,
move distributor levers to circulate in tank position (Fig.
72). Next, let fifth wheel down and with P T.O. engaged
drive distributor forward at a steady speed of 300 ft/min.
While driving at this steady speed, adjust micro control
until pump flow rate is 100 gal/min Hold micro control in
this location by turning lock tube up against under side of
micro control knob After locking knob in place, increase
distributor ground speed to 450 ft/min Pump flow rate
should be 150 gal/min. Next, decrease speed to 200
ft/min and flow rate should drop to 75 gal/min. If these
ground speeds and flow rates do not correspond, check
and pump suction port Tighten fittings as necessary Air

input equals 1000 FPM reading Therefore, if R P.M. of
say an electric drill press, for example, is known to be
600 R P M., then the ground speed indicator should read
600 ft/mm. when driven by the drill press. If ground
speed indicator, (bitumeter) checks satisfactory proceed
to check pump flow indicator.
