Rephasing Lift System
Over a period of normal use the cylinders may get
out of phase. This will cause some drill sections to
run higher than others. To rephase cylinders:
1.
Raise the implement completely and hold the
hydraulic remote lever on for several seconds
until all cylinders are fully extended. Do this
every 3 0r 4 times you raise drill out of ground.
2.
When all cylinders are fully extended, mo-
mentarily reverse hydraulic remote lever to re-
tract system 1/2 inch to maintain levelness.
