Hydraulic Charge
The hydraulic system was fully charged and bled when
the drill left the factory. If any changes were made prior to
delivery (such as installing markers), or there is any
question about the status of the system, see “Bleeding
Hydraulics” on page 54.
After some use, it is normal for the lift cylinders to get out
of phase. If one or more sections are not fully lifting, or
are lifting to different heights, see “Re-phasing Lift
System” on page 24.
Drill Level
A new drill has been aligned at the factory and should
not require adjustment prior to first use. Level needs to
be checked periodically, and possibly adjusted.
See “Leveling Drill” on page 56
