6. Even after the engine is started, do not touch the work
equipment control levers and the travel pedals, while the
engine hydraulic pressure monitor lamp is still lighted.
NOTICE
If the engine oil pressure monitor does not go out even
after 4 to 5 seconds have passed, stop the engine immedi-
ately. Check the oil level, check for leakage of oil, and take
the necessary action.
REMARK
Regardless of the ambient temperature, it is possible to start
the engine preheating manually.
1. Turn the key in starting switch (3) to the left from OFF posi-
tion (A). The preheating monitor lights up and engine preheat-
ing starts.
(Preheating continues while the key in starting switch (3) is
held at the left position.)
2. The preheating monitor starts lighting about 30 seconds after
preheating starts and then goes off in about 10 seconds.
3. After the preheating monitor goes off, turn the key in starting
switch (3) to START position (C). The engine will start.
If the engine cannot be started with the above procedure, wait
for at least two minutes, then start again from Step 1.

The relationship between the turbocharger protection function and an engine cooling water temperature is as
shown in the table below.
The engine revolution dose not rise above 1000 rpm within the time shown in the table, even if the fuel control dial
is operated.

q In cold weather, the turbo protect function is actuated, so the engine speed is maintained below 1000 rpm for
several seconds. After that, the automatic warming-up function raises the engine speed to 1200 rpm.
