Bleeding Lift Assist Hydraulics
!
WARNING!
Crushing hazard. The hydraulics could fail, causing
the soybean machine to fall and crush you. Never work
under the raised soybean machine unless secured with
channel locks. Never bleed an O-ring fitting, which
could damage the seal and cause the implement to
drop rapidly.
The lift-assist hydraulics must be free of air. If the
lift assist raises with jerky, uneven motions, or if a
hydraulic component is replaced during the life of
the lift assist, follow these steps to bleed air from
the hydraulics.
1. Check that the tractor hydraulic reservoir is
full.
2. Loosen tee fitting on one side of tee. Engage
tractor hydraulic lever for the lift assist until oil
appears at loosened fitting. Tighten fitting.
25. Place warning decals (4) on outside of frame-
arm plates at locations shown.
26. Place lubrication decals (5) at locations
shown.
