Kegel FLEX 17-5801 Operator's Manual page 69

Whenever the OIL DISTANCE is increased the last BUFF LINE will need to be adjusted to the
OIL DISTANCE. When this change is made, the program will automatically change the OIL
DISTANCE to the 15th Forward BUFF LINE (F15). You will need to fix this.
The rest of the LINES, work just like the Forward screens. Row R2 will be the first LINE to
have LOADS.
The DISTANCE will automatically be calculated when the
LOADS & SPEEDS are entered. It is possible to have more
than one BUFF LINE during the return trip to the foul line,
by entering lines until you hit zero footage as the lower
limit.

After the forward screens are complete, through F15, the
screen will advance to REVERSE SCREEN I. "R1", the first
reverse line, will be used for buffing only. With the machine
traveling in reverse, the buffer brush will drop wherever the
REVERSE DROP BRUSH is set to and buff the lane until the
END DIST is reached. The END DIST is also where the
beginning of where the Reverse oil will start to be applied.
Like the Forward screens, once you have created BUFF LINES
you cannot create the next LINE with LOADS; the present
program does not allow skipping.
