OPERATION
EXPLANATION OF COMPONENTS
FUEL GAUGE
This meter (3) shows the amount of fuel remaining in the fuel
tank.
During normal operations, the indicator should be in the green
range.
If the indicator goes down to the E position during operation,
there is less than 3.5 l remaining, so check and add fuel.
When the starting switch is turned ON, the meter may not indi-
cate the actual level for a short time, but this is not an abnor-
mality.
ENGINE PRE-HEATING MONITOR
This monitor lamp(4) indicates the pre-heating time required
when starting the engine at an ambient temperature below 0°C
(32°F).
The monitor lamp lights when the starting switch is turned to
HEAT position and goes off after about 18 seconds to show
that the pre-heating is completed.
