the preheat lamp is turned off. (Ap-
prox. 8 sec)

the seat + Depressing Clutch
pedal. (Shuttle lever, PTO and

IMPORTANT
The glow plug lamp comes on for 8
seconds and then goes off when the
key switch is turned to the "ON" posi-
tion.
The engine should be started within
5 seconds after the glow plug lamp
goes off. After the engine is started,
post-heat is performed for 15 sec-
onds with the key switch in the "ON"
position.
The preheat/after-heat function and
glow plug lamp do not operate when
the coolant temperature is 30°C (86°
F) or higher. In this case, the engine
can be started without the preheat
operation.
* The post-heating is a function to
keep the preheating function acti-
vated for approx. 15 seconds after
the engine is started in order to
enhance the engine combustion
performance and reduce harmful
emissions right after engine start.
OPERATING PRINCIPLE OF PREHEAT SYSTEM
10. Warm up the engine for 3 to 4
minutes (10 minutes in winter)
after releasing the clutch pedal.
9. When the engine is started, re-
lease the key. Then, the key is
automatically turned back to the
"ON" position.
Never operate the start motor
for 10 consecutive seconds as
it consumes a lot of power. If
the engine cannot be started
within 10 seconds, wait for 30
seconds and try again.
When trying to start the engine
again, make sure that the fly-
wheel is stopped in advance.

the "Start" position while the
