Warm-up in cold ambient temperatures
In cold weather, the engine oil may be cold with
increased viscosity. This can delay oil circulation or
abnormally low oil pressure for some time after engine
start-up. This can result trouble in the lubrication
circuit or damage to the engine moving parts.
To prevent the above problems, perform the following
instructions:
Warm up the engine at rated revolution with no load.
Ambient temperature
Above 0°C (32°F)
0°C (32°F) to -10°C (14°F)
Below -10°C (14°F)
