PERATION
T h e c u r r e n t o f f u e l w a r m e r s y s t e m i s
automatically controlled without thermostat
according to fuel temperature.
At the first state, the 15A current flows to the fuel
warmer and engine may be started in 1~2
minutes.
If the fuel starts to flow, ceramic-disk in the fuel
warmer heater senses the fuel temperature to
reduce the current as low as 1.5A.
So, fuel is protected from overheating by this
mechanism.
