WARNING:
Make sure that there is no flammable near outlet port of
exhaust gas at engine starting. It is very dangerous due to
deformation, discoloration or a fire.
(3) Engine Starting
1) Depress the engine throttle lever or throttle pedal and turn the starter
switch key clockwise to START position.
The cranking period must not exceed ten seconds.
Continuous starter operation of more than ten seconds will lead to
overdischarge of the batteries as well as starter seizure.
Release the starter switch after the engine starts.
The switch will return to the "DRIVE" position automatically.
For the engine equipped with a safety unit, the starter circuit is
automatically turned off when the engine starts. This prevents the
starter from overrunning.
If the engine cannot be started in one time attempt, keep the batteries
and the starter stationary at least 30 seconds for their functional
recovery, then repeat the pre-heating and the starting operations.
CAUTION:
Continuous re-engagement of the starter to the flywheel ring
gear without giving them a break will result in the damaged
starter pinion gear and flywheel ring gear.
2) If, despite repeated operations, the engine does not start, wait for a
minute or more until the functions of the batteries and starter are
recovered and then repeat pre-heating and starting operations.
