7. Repin cylinders to hitch frame. Reinstall short com-
pression springs on cylinder-support-brace bolts and
re-tighten 1/2-inch nylock nuts until springs are com-
pressed to 32 mm (1 1/4 inches). If for any reason the
1/2-inch jam nuts in centre of support-brace bolts
were changed, refer to Transport Cylinder Support
Brace, page 32, for proper adjustment.
8. Refill tractor hydraulic-fluid reservoir to proper level.
Bleeding Marker Hydraulics
!
CAUTION!
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 the
markers.
1. Check that tractor hydraulic reservoir is full.
2. With both markers lowered into field position, loosen
hydraulic-hose fittings at rod and base ends of marker
cylinders. Loosen fittings on back side of sequence
valve.
3. With tractor idling, activate tractor hydraulic valve until
oil seeps out around a loosened fitting. Tighten that fit-
ting.
4. Reactivate tractor hydraulic valve until oil seeps out
around another loosened fitting. Tighten that fitting.
Repeat process until all loosened fittings have been
bled and tightened.
IMPORTANT: Never bleed an O-ring fitting. Instead,
bleed a nearby pipe or JIC fitting.
IMPORTANT: JIC fittings do not require high torque.
JIC and O-ring fittings do not require sealant. Always
use liquid pipe sealant when adding or replacing pipe-
thread fittings. To avoid cracking hydraulic fittings from
over tightening, do not use plastic sealant tape.
