1. Use the UP or DOWN ARROW
until LL:02 displays. This will set

dle-style" low level algorithm (like
the Graco G3 grease units). To
ensure a low level condition has
been met in this mode, 10 consec-
utive low level triggers must be
detected. If a low level trigger is
not detected in 30 seconds of run
mode, the count is reset to zero.
2. Press the ENTER button.
