Fuel Filter Restriction
This gauge tells you the condition
of the fuel lter by indicating the
restriction from the fuel lter to the fuel
pump. Check the engine manual for
proper restriction. Replace the lter
with an approved lter 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 manufacturers manual or engine
dealer for fuel restriction specica
-
tions.
Air Filter Restriction
Indicator or Gauge
This gauge indicates the condition of
the engine air cleaner.
CAUTION
Continued operation with the dirty air
lter may cause damage to the engine.
Inspect the lter and replace if neces
-
sary. Holes in the paper element ren-
der an air cleaner useless and may
cause the Air Filter Restriction Gauge
to give a false reading, even if the ele
-
ment is clogged. Replace 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.
