• Avoid operation with heavy loads or at high speeds.
• Immediately after starting the engine, avoid sudden starts, sudden acceleration, unnecessary sudden
stops, and sudden changes in direction of the machine.
METHOD FOR ENGINE WARM-UP OPERATION
NOTICE
• Do not accelerate the engine abruptly until it is warmed up.
• Do not run the engine at low idle or high idle with no load for 20 minutes or more. This will have an
adverse effect on the environment and also on the internal structure of the engine. If it is necessary
to run the engine at idle for 20 minutes or more, apply a load from time to time or run at a medium
speed.
This machine is equipped with an automatic engine warm-up system, so if the engine coolant temperature is
30 °C or less after the engine is started, the engine warm-up operation starts automatically. When the engine
automatic warm-up operation starts, the engine speed is maintained higher than the normal speed at low idle.
If the engine coolant temperature goes 30 °C or more or if the warm-up operation is continued for more than 10
minutes, the automatic warm-up operation is cancelled and the engine speed drops to the normal speed at low
idle.
Do not start operating the machine immediately. First, perform the following operations and checks.
1.
Check that the engine coolant temperature caution lamp
(1) displays the correct temperature.
If it displays the low temperature, perform additional warm-
up operation according to step 2 until it displays the correct
temperature.
• Display (A) when temperature is correct: Caution lamp
background (C) is blue.
• Display (B) when temperature is low: Caution lamp
background (C) is white.
2.
Turn the fuel control dial (2) to the middle between Low
idle (MIN) and High idle (MAX) to run the engine at a medi-
um speed.
