GAUGES
Y
FILTER MINDER
The air filter gauge (1) (FILTER MINDER) is
located just above the ground-control panel. The
gauge measures the vacuum (air pressure)
between the intake manifold and the air filter. As
the filter clogs, the vacuum increases (pressure
drops). As the vacuum increases, the yellow
indicator disk (2) raises toward the red area (3)
of the sight glass. When the yellow disk reaches
the red, it’s time to change the air filter.
The indicator disk (2) stays at its highest setting,
it does not go to the bottom of the sight glass
when the engine is turned off. After the filter is
changed, press the small RESET button (4) to
reset the indicator disk to the bottom of the sight
glass.
Y
TEMPERATURE
The TEMPERATURE gauge is located at the top
of the ground-control panel. For Ford engines it
shows the temperature of the water-antifreeze
mixture in the engine block. The typical
operating-temperature range for Ford engines is
160°F to 190°F (71°C to 88°C).
The TEMPERATURE gauge for Deutz engines
shows the temperature of the engine oil as the oil
leaves the oil filter. The typical operating-
temperature range for a Deutz engine is 172°F to
203°F (78°C to 95°C).
Y
AMPS
The AMPS gauge shows the electric current
from the alternator to the battery(ies). When the
engine is running, the needle in the AMPS gauge
should not be to the left of “0.” Under normal
operating conditions, after the engine has been
running for a few minutes, this gauge should
read “0.”
Y
HOURS
1
2
The HOURS gauge (1) is located on the wiring
box (2), to the left of the ground-control panel
(behind the cowling door). The HOURS gauge is
basically an electric clock. It accumulates time
when the BATTERY, EMERGENCY STOP (at
the ground), and MASTER switches are all in the
ON position. The HOURS gauge cannot be
reset. Use it to tell when it is time for 150 hour or
500 hour maintenance.
