NOTICE
If the engine is abruptly stopped before it has cooled
down, engine life may be drastically shortened. Do not
abruptly stop the engine except for an emergency.
If the engine has overheated, do not stop it abruptly, run it
at medium speed allowing the engine to gradually cool
down, then stop it.
1. Lower the work equipment to the ground.
2. Place fuel control dial (1) in the low idle (MIN) position and
run the engine at low idle speed for about 5 minutes to
allow it to gradually cool down.
