5. Connect hydraulic hoses to tractor ports in a sequence familiar and comfortable to the operator.
Wipe hose ends to remove any dirt
before connecting couplers to tractor
parts or contamination may cause
equipment failure.
NOTICE
Pressurized hydraulic fluid can penetrate
body tissue and result in death, serious
infection, or other injuries. Fluid injected
under skin must be IMMEDIATELY
removed by a surgeon familiar with this
type of injury. Make sure connections
are tight and hoses and fittings are
not damaged before applying system
pressure. Leaks can be invisible. Keep
away from suspected leaks. Relieve
pressure before searching for leaks or
performing any system maintenance.
WARNING
Connect hydraulic motor case drain to
a case drain return line with zero PSI
on tractor. Failure to connect to a return
with zero PSI will cause hydraulic motor
shaft seal damage. DO NOT connect
hydraulic motor case drain to a SCV
outlet or motor return circuit connection.
Contact tractor manufacturer for specific
details on “zero pressure return”.
NOTICE
Always connect hydraulic motor return
hose to tractor motor return port. Do not
connect to tractor SCV unless through
a motor spool or hydraulic motor failure
can occur. If a motor return port is
not available on the tractor, the SCV
controlling the bulk fill system MUST
be in the float position before planter is
moved in planting or field raised position
when bulk fill system is not in use.
