Strainers - One is provided in the filling line (fig. 3-8), one in the discharge header (fig. 24) between the
pump and control valves, one in the manhole (fig. 3-5), one in the fuel lines (fig. 3-4), and one at each burner control valve
Transfer Valve - "Leakless" type Quick-action union connections for transferring material at full pump
capacity. Complete with Morrison Couplings for attaching filling hose or hand spray hose.
Pump - Heavy-duty, rotary gear type Capable of supplying bitumen to the 24-foot spray bar with sufficient
pressure to produce an even, fanlike spray from all nozzles at any rate of application within the distribution range of 1/10 to
1 gallon per square yard. Capacity, 400 gpm
Filling Line - Quick-acting, screw-clamp, hinged-type connection with Morrison Couplings, for connecting
filling hose Located in front of left operator's platform
Pressure Gages and Control Valves. The gages and valve (fig. 2-5) provide the operator visual indications and
control of hydraulic oil pressure
Air Pressure Gage - Provides visual indication of the air pressure in the distributor system Indicates 0-160
psi Normal reading is 120 psi.
Motor Control Valve - The valve has an On/Off position to control the flow of hydraulic fluid to operate the
Hydraulic Pressure Gage - (Fig. 2-5) provides visual indication of the hydraulic pressure developed in the
distributor system. Indicates 0-5000 psi. Maximum pressure is 4000 psi
Fuel Pressure Gage - Indicates the amount of fuel pressure applied to the burners to mix air for ignition.
Indicates 0-100 psi. Normal reading is between 10-15 psi.
