Maintenance
Before
each
day:
It
is
highly
recommended
that
the
sprayer
friction
pads
are
greased.
Ensure
there
is
a
clean,
dry
foam
disc
inserted
in
each
sensor.
If
it
is
clogged
with
dust
or
other
debris,
clean
it
as
described
below.
Cleaning
Ultrasonic
Height
Sensors:
Remove
the
foam
disc
from
the
sensor
and
wash
it
with
clean
water.
Squeeze
out
water
and
allow
the
foam
disc
to
dry.
If
the
transducer
inside
the
sensor
is
also
dirty,
wash
it
using
clean
water.
Do
not
submerge
or
pressure
‐
wash
the
sensor.
Chemicals
or
compressed
air
should
never
be
used.
The
sensor
can
be
used
if
it
is
wet,
however
a
valid
height
reading
may
not
be
obtained
until
it
is
completely
dry.
