WA470-6H – VEAM946100
The time that the preheating pilot lamp (2) stays lighted up
depends on the ambient temperature as shown in the table
on the right.
2. If the preheating pilot lamp (2) does not light up, or it lights
up and then goes out to inform that the engine preheating
has been completed, turn the key in starting switch (1) to the
START position (C).
3. The starting motor will continue to turn and the engine will
start.
Keep the key in starting switch (1) at the START position (C)
to keep the starting motor running until the engine starts.
REMARK
In low temperatures, to ensure lubrication of the engine and to
improve the durability, no fuel is supplied to the engine for 3 sec-
onds after the key in starting switch (1) is turned to the START
position (C), so the engine will not start during this time.
Therefore, keep the key in starting switch (1) at the START posi-
tion (C) to keep the starting motor running until the engine starts.
4. After the engine starts, release the key in starting switch (1).
The key will automatically return to the ON position (B).
5. After the engine starts, if the engine water temperature is low
(below 20°C), the warming-up operation (engine speed:
1020 rpm) is automatically carried out.
6. For details, see "Automatic warming-up operation (3-109)".
REMARK
Keep the accelerator pedal depressed after the engine starts up,
until engine warming-up run is finished. Do not step on the pedal
to the full stroke.
REMARK
Immediately after the engine is started, the turbo protect function
is actuated. Even if the accelerator pedal is depressed, the
engine speed will not rise above 1,000 rpm.
The turbocharger rotates at extremely high speed. Immediately
after the engine is started, the pressure of the lubricating oil has
not risen sufficiently, so if the engine speed is suddenly raised, it
may lead to damage or seizure of the turbocharger bearing. The
turbo protect function acts to prevent this problem. It uses elec-
tronic control to prevent the engine speed from rising above a
certain speed for the first few seconds after the engine started.
