STARTING IN COLD WEATHER
WARNING
●
Check that there are no persons or obstacles in the sur-
rounding area, then sound the horn and start the engine.
●
Never use starting aid fluids as they may cause explo-
sions.
NOTICE
Do not keep the starting motor rotating continuously for
more than 20 seconds.
If the engine fails to start, repeat steps from 2 after waiting
for 2 minutes.
When starting in low temperatures, do as follows.
1. Set fuel control dial (7) at the low idling (MIN) position.
2. Hold the key in starting switch (6) at the HEAT position, and
check that preheating monitor lights up.
After about 30 seconds, preheating monitor will flash for
about 10 seconds to indicate that preheating is finished.
REMARK
The monitor and gauge also light up when the key is at the
HEAT position, but this does not indicate any abnormality. If the
temperature is low, the monitor screen may become dark or it
may take time for the display to appear. This is normal.
