When prompted, move the lever toward the
mast, the A direction, until the forks begin to
creep. Creep means moving the forks as
slowly as possible. Press the Enter Key and
the system records the valve reading.
When prompted, move the lever toward the
rear of the truck, the B direction, until the
forks begin to creep and press the Enter
Key. The system records the valve reading.
Steps 5 and 6 provide the hydraulic input for
function 1.
NOTE:
If a valve reading is not within the accept-
able range, an abort message appears. Press any
key to continue.
