Bleeding Marker Hydraulics
Crushing and Sharp Object Hazard:
You may be injured if hit by a folding or unfolding marker.
Markers may fall quickly and unexpectedly if the hydraulics
fail. Never allow anyone near the drill when folding or
unfolding markers.
1.
Review warnings, bleeding notes and system
information on page 68.
2.
With markers unfolded in field position, crack
hydraulic-hose JIC fittings
at base and rod ends of
each marker cylinder.
3.
With tractor at idle speed, activate tractor hydraulic
valve forward until oil appears at a fitting. When oil
begins to seep out around a fitting, tighten that fitting.
Reverse the tractor hydraulic valve until oil appears
at opposite hose fitting. Tighten that fitting.
4.
If you have dual markers, activate tractor hydraulic
valve forward again until oil seeps out around a fitting
on the other marker cylinder. Tighten that fitting.
Reverse tractor hydraulic valve until oil seeps out
around remaining hose fitting and tighten it.
5.
Fold and unfold markers slowly to work out all air.
NOTE:
Use caution when folding and unfolding markers for
the first time, checking for pinching and kinking of
hoses.
