8. Unlock the display if the security function had been
activated. When operating the machine in severe
winter climates, the engine preheating icon is dis-
played as the engine is being preheated automati-
cally.
The engine is preheating.
Wait for the auto preheat to complete and the icon to
disappear.
9. Sound the horn with the button on the left control lever
to warn that the machine is starting up.
10. Turn the starter key (2) to START position. The en-
gine running takes approximately 1 s to stabilize after
it has been cranked up. Release the starter key as
soon as the engine is running regularly.
NOTICE: The cranking up of the engine may be difficult in severe winter climate. If the engine does not start after
10 s of operation of the starter motor, turn the key to OFF position and wait 2 min before attempting a new cranking.
NOTICE: When the engine is started in severe winter climate, moisture vapor may be temporarily generated resulting
in a whitened smoke.
NOTICE: Immediately after the engine is started, the engine sound is louder compared to the sound after the engine
is warmed up, and also the color of the exhaust smoke becomes more whitened or more blackened than the smoke
emitted during the normal operation. The engine sound and the color of the exhaust smoke get smoothed after the
engine is warmed up.
NOTICE: Due to resonance, vibration might come up while the engine is running at low speed. Increasing slightly the
engine speed reduces the vibration.
The seat belt icon turns on after the engine is started in
order to remind the operator to securely fasten the seat
belt.
Fasten the seat belt.
