●
The type with an indicator light, 10 seconds are
required until the indicator light at the instrument panel
goes off.
2. Turn the starter key clockwise to the “START” position
as soon as the indication lamp goes off.
(3) Engine Starting
1. Depress the engine throttle lever or throttle pedal and
turn the starter key clockwise to the “START” position.
The cranking period must not exceed ten seconds.
Continuous starter operation of more than ten seconds
will lead to over discharge of the batteries as well as
starter seizure.
If the engine cannot be started in a one time attempt, wait
at least 30 seconds for their functional recovery, then
repeat the pre-heating and the starting operations.
CAUTION: Continuous re-engagement of the
starter to the flywheel ring gear will result in dam-
aged starter pinion gear and flywheel ring gear.
2. If, after repeated attempts, the engine does not start, wait
for a minute or more, then repeat pre-heating and starting
operations.
3. When repeating starting operation, return the key to the
OFF position and then pre-heat and start the engine once
again.
If the engine still will not start, something may be wrong
with the engine. Contact your Authorized Hustler Turf
dealer/service shop if the problem can not be located.
CAUTION: Do not use starting "aids" in the air
intake system. Such aids can cause immediate
engine damage.
6.3 Check and Operation After Engine Start-up
(1) Engine Warm-up Procedure
Run engine at Low or Middle speed about ten minutes
after the engine has started.
As the lubrication for the entire engine systems will be
done in this warming-up, do not speed up and load it abruptly.
Particularly, observe this in cold season operation.
(2) Check After the Engine Start-up
Check the following items during engine warm-up opera-
tion.
1. Engine oil pressure
Check to see if the oil warning lamp is off.
2. Charge condition
Check to see if the charge warning lamp is off.
3. Engine noise and exhaust smoke color
Pay attention to engine noise and, if any abnormal noise
is heard, check the engine to detect the cause.
Check the fuel combustion condition by exhaust smoke
color.
The exhaust smoke color after engine warming-up and at
no load operation:
Colorless or
light blue . . . . . .Normal (Perfect combustion)
Black color . . . . . . .Abnormal (Imperfect combustion)
White color. . . . . . .Abnormal (Imperfect combustion)
CAUTION: Engine noise after start-up might be
noisier than that of warmed-up engine and, the
exhaust smoke color also may be blacker than the
normal condition. However, it should normalize
after warm-up.
Leakage in the systems
Check the following items:
1. Oil leaks
Check both sides and bottom of the engine assembly for
oil leaks, paying particular attention to the oil pressure
gauge pipe joint, oil filter and oil pipe joints.
2. Fuel system leaks
Check the fuel injection pump, fuel lines and fuel filter
for leakage.
3. Coolant leaks
Check the radiator and water pump hose connections and
the water drain cocks on the radiator and cylinder blocks
for leakage.
4. Exhaust smoke or exhaust gas leakage
Checking coolant level
The coolant level could drop depending on the equipment
because the mixed air is expelled in about 5 minutes after the
engine started. Let engine cool before removing radiator cap.
Stop the engine, remove radiator cap, and add coolant.
WARNING: Hot steam will rush out and you
could get burnt, if the radiator cap is removed
when the engine is hot. Allow engine to cool
before removing radiator cap.
Cover the radiator cap with a thick cloth and
loosen the cap slowly to reduce the pressure, then
remove the cap.
6.4 Precautions During Engine Operation
During engine operation, always pay attention to the fol-
lowing items if the engine indicates any sign of abnormalities.
(1) Engine Oil Pressure
1. When the engine is warmed up at the specified speed, and
the oil warning lamp is off, the oil pressure is normal.
2. When the oil warning lamp is flashing with the increased
engine speed, stop the engine immediately and check the
engine oil level or for an oil leak.
If the engine oil level is within proper operating range
and no leaks are found contact your local Authorized
Hustler Turf dealer/service shop.
