THE
DAILY
ROUTINE
CHECK
LIST
Each day before starting your engine, take a few moments to
run this check list:
D Visually inspect the engine for fuel, oil, coolant and
exhaust leaks.
D Check the oil level.
D Check the transmission fluid level.
D Check for loose wires at the alternator.
D Check for loose wires and electrical connections at the
DC
alternator and elsewhere on the engine's
DC
harness.
D Check the starting batteries level (weekly)
D Check drive belts for wear and proper tension (weekly).
D Log your engine running time. These hours relate to
scheduled_maintenance.
D Check fuel supply; always keep fuel tank(s)
as
full as
possible.
D Look for clean fuel in the fueVwater separator bowl.
. D Check the coolant level in the plastic recovery tank.
D Check for any obviously loose components
or
nuts or
bolts.
NOTE:
Excessive
loss
of
coolant indicates a cooling system
leak.
Check
the
entire
system.
If
necessary,
use
a cooling
sys-
tem
pressure tester
to
pressurize the cooling system
to
locate
the
area
of
leakage.
In
cases
of
excessive coolant
loss,
refill
the
system as outlined
in
the
ENGINE COOLING CIRCUIT
section
in
this
manual.
START
YOUR
ENGINE
NOTE:
See
STARTING STOPPING PROCEDURE
in
this
manual for
more
detailed·
instructions.
1.
Put
transmission in neutral, throttle advanced.
2.
Tum
KEY to the
ON
position (2
0'
clock)
3.
Depress PREHEAT (10 to
15
seconds).
4. While pressing PREHEAT, push the START.
As engine fires - release START and PREHEAT.
5.
Observe the panel gauges, check the oil pressure, DC
charges, etc. Check for water discharge with the exhaust.
NOTE:
Should engine fail
to
start,
wait 30
seconds,
repeat
the
above
procedure,
and PREHEAT
longer.
6.
Allow a few minutes for the engine to warm at a
comfortable high idle
(1400- 1500 rpm), then reduce the
rpm to the normal idle position, shift into gear, and get
underway.
A
CAUTION:
When
shifting
the
transmission,
always
reduce
the
engine
rpm
to
idle,
then
shift
the
transmission
firmly
from
one
direction
to
another.
A
slight
pause
in
neutral
will
allow
the
propeller
to
slow.
Shifting
at
high
rpm
will
damage
the
transmission/damper
plate.
ALARMS
AND
CIRCUIT
BREAKER
ENGINE
CIRCUIT
BREAKER
The
DC
harness on the engine is protected by an engine-
mounted manual reset circuit breaker
(20 amps DC).
Excessive current draw
or
electrical overload anywhere in
the instrument panel wiring
or
engine wiring will cause the
breaker to trip. In this event most engines will shut down
because the open breaker disconnects the fuel supply.
If
this should occur, check and repair the source
of
the problem.
After repairing the fault, reset the breaker and restart the
engine.
LOW
OIL
PRESSURE
ALARM
SWITCH
A low oil pressure alarm switch is located off the engine's
oil gallery. This switch's sensor monitors the
eugine's oil
pressure. Should the engine's oil pressure fall to 5
-1.Q
psi
(0.4 - 0.7 kg/cm
2
),
this switch will activate a pulsating alarm.

SWITCH.
COOLANT
TEMPERATURE
SWITCH
A coolant temperature switch is located on the thetmostat .
housing. This switch will activate a
continuous
alarm
if
the
coolant's operating temperature reaches approximately
210"F (99°C).
