Installing the Valve
Preparation
Hook the drill to a tractor. Move the opener lock
handles to "Field", unfold the drill and lower the
openers to the ground. Place the remote lever in
float position to relieve any residual hydraulic
pressure. Place tractor in park, turn off engine and
remove the key before preforming any mainte-
nance on the drill. Clean the area around the
pressure reducing valves by washing or using
compressed air.
!
WARNING!
If using compressed air to clean around the pressure
reducing valve make sure and keep others out of the
area and always wear safety goggles and face shield.
