Marker Hydraulics
Never allow anyone near the drill when cycling the markers.
1.
Make sure the tractor hydraulic fluid reservoir is filled
to the proper level. It will take one gallon to charge
the dual marker cylinders.
2.
With the drill unfolded and lowered, turn marker
switch on the control console to the left marker
position.
3.
With the marker unfolded, crack the hydraulic hose
fitting located at the base end of the left marker
cylinder.
4.
With the tractor at idle slowly work the tractor remote
lever to feed oil to the base end. Stop when you see
oil coming out around the hose ends. Tighten the
hose-end fittings.
5.
Repeat step 3 and 4 for the hose-end fitting at the
rod end of the cylinder.
6.
If dual markers are used, repeat steps 2, 3 and 4 for
the right marker cylinder.
Leave the control console switch in the left marker position
when bleeding the right marker cylinder. Both markers are
controlled by the left marker switch if your markers have a
sequence valve.
7.
Fold and unfold the marker slowly to work all the air
out of your marker hydraulics.
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 possible
danger of cracking hydraulic fittings from over tightening, do
not
use plastic sealant tape.
