OPTIONAL GAUGES
Fuel Filter Restriction
This gauge tells you the condition
of the fuel filter by indicating the
restriction from the fuel filter to the fuel
pump. Check the engine manual for
proper restriction. Replace the filter
with an approved filter only. Do not
substitute the wrong micron element.
NOTE
The maximum allowable restriction
could vary according to the type or
make of engine.
Consult the en-
gine manufacturer's manual or en-
gine dealer for fuel restriction speci-
fications.
Air Filter Restriction
Indicator or Gauge
This gauge indicates the condition of
the engine air cleaner.
CAUTION
Continued operation with the dirty air
filter may cause damage to the en-
gine. Inspect the filter and replace
if necessary. Holes in the paper el-
ement render an air cleaner useless
and may cause the Air Filter Restric-
tion Gauge to give a false reading,
even if the element is clogged. Re-
place the element if it is damaged.
Engine, Oil Pressure
It is important to maintain oil pressure
within acceptable limits. If oil pressure
drops below the minimum psi a red
warning light in the gauge will turn on,
the Stop Engine light will come on and
an audible alarm tone will sound.
