Table 2-2. Hydraulic System Gages and Controls
Key
Gage or Control
Function
1
Hydraulic Pressure Gage
(Primary Mainifold)
Shows hydraulic fluid pressure for entire
hydraulic system.
2
Hydraulic Pressure Control
Knob (Primary Mainifold)
(LV and ULV) Permits adjustment of hydraulic
pressure to primary manifold pesticide pump,
allowing boom pressure (flow rate of liquid
pesticide) to be regulated. Also controls speed
of rotary atomizers.
3
Hydraulic Pressure Gage
(Secondary Manifold)
Shows hydraulic fluid pressure for dispersal
valve in LV and ULV configurations, and for
chute gate actuators in SD configuration. This
manifold is normally adjusted for 300 psi. If
adjusted above 400 psi, damage to hydraulic
system could occur.
4
Hydraulic Pressure Control
Knob (Secondary Manifold)
Permits adjustment of hydraulic pressure to
dispersal valve and chute gate actuators.
