Engine Low Oil Warning Horn
The engine low oil warning horn gives an audible
signal that the engine oil quantity in the crankcase is
below the safe operating range. The signal will also
occur when operating the machine on steep slopes
(greater than 25 degrees) and the angle of operation
may
cause engine damage from insufficient lubrica
tion. If the horn is sounding when operating on flat
ground, stop the machine and check/adjust the en
gine oil level as noted in
LUBRICATION
for
Check-
ing Engine Crankcase Oil Level
in
Maintenance In
structions.
If the horn is sounding when operating on
a slope, stop the machine and check/adjust the en
gine oil level (on a level surface), and then reduce
the angle of operation if the horn continues to sound
on the slope
.
IMPORTANT:
Continued operation of the engine
with the engine low oil warning horn sounding
MAY
cause engine damage if not corrected as soon as
possible.

* These intervals reflect the actual time that the
reminder will flash (one hour prior to and one

** This reminder is only used one time.
*** In normal operating conditions, oil changes in
100-hour intervals are acceptable. Walker and
the engine manufacturers recommend engine
oil changes every 50 hours in extremely dirty or
dusty conditions or for units with less than 100
hours annual use.

The blinking hour glass on the display
means that the meter is operating properly.
