Pre-Start Checklist
Implement Lift
The drill has six rephasing lift cylinders that raise and
lower the opener frame. Lift is on a dedicated circuit not
shared with any other air cart or drill functions.
Four (4) transport locks are provided, one each for the
rockshaft (center forward) and lift-assist (rear) cylinders.
These assure that the drill stays raised during
folding/unfolding, transport, storage, lubrication,
maintenance and some setup/adjustment tasks.
Lift
Over a period of normal use the cylinders may get out of
phase. This causes some implement sections to run
higher than others when lowered. To minimize this, or
rephase the cylinders, make the following steps your
normal raise sequence:
1. Raise the implement completely and hold the
hydraulic remote lever on for several seconds until all
cylinders are fully extended. Do this every time you
raise the implement out of the ground.
2. When all cylinders are fully extended, momentarily
reverse the hydraulic remote lever to retract the
system
1 ⁄
2
inch to maintain levelness.
If implement is still not level after re-phasing, see
“Bleeding Lift Hydraulics” on page 17 and “Level
Frame Side to Side” on page 19.
❑ Lubricate the drill as indicated under Lubrication,
“Maintenance and Lubrication” on page 54.
❑ Check the tires for proper inflation according to “Tire
Inflation Chart” on page 63.
❑ Check for worn or damaged parts and repair or
replace before going to the field.
❑ Check all nuts, bolts and screws. Tighten bolts as
specified on “Torque Values Chart” on page 64.
❑ Check implement lift switch on drill.
❑ Complete all pre-start checklist items on the air cart.
