AMPS
The AMPS gauge shows the electric current
from the alternator to the batteries. 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.”

ENGINE OIL
CONTINENTAL CUMMINS
2
Engine oil level is measured with a dipstick (1)
(2). Oil sump and oil filter capacities given in the
“SPECIFICATIONS” chapter are approximate.
True values may vary from machine to machine
due to slight variations or modifications during
production. The oil dipstick is the only way to
accurately gauge if the engine oil level is correct.
CONTINENTAL CUMMINS
3
4
Engine oil level should always be in the cross-
hatched area (3) (4) of the dipstick — never
above or below it. Check the oil level after the
engine has been turned off a few minutes so that
oil can run down out of the engine into the sump.
T
FILTER MINDER
The air filter gauge (1) (FILTER MINDER) is
located just above the ground-control box. 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 (2) raises toward the red area (3) of the
sight glass. When the yellow indicator reaches
the red, it’s time to change the air filter.
The indicator (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.
