The heater must be checked carefully before use, ensuring
that there are no leaks and that all connections are in safe
conditions. If dense smoke, fuel smells or irregular noise
become apparent, the heater must be shut down and the
fuse removed. The heater must only be put back into use
after repair by a qualified professional.

3.confirm thatgapbetweenthe wheelmagnetandcontroller’s Hallsensoris not excessive;
4.confirm thatthepower lineis notin a short-circuitoropen-circuit state;
5.Electric leakage.
1. confirmadequate fuel,and absence of lowtemperaturesolidificationoffuel orother blockageinfuel
pipeline andfuel pump;
2. Confirm thatintakeandexhaustductsarenot blocked;
3. confirm thathousingtemperaturesensorisin completecontactwiththehousing,and thepressurespring
isapplying adequate pressure.
1.confirm that the fuel has not run out;
2.confirm that the fuel pipelines are not frozen or blocked;
3.confirm that the fuel pump is operating normally:
3.1 confirm that there is no air trapped in the fuel line causing discontinuous fuel supply;
3.2 confirm that the fuel is of adequate quality;
3.3 refer to fault code E-8 for other pointers.
1.sensor connectors are damaged or have loosened;
2.sensor is damaged.

2.4 confirm that intake and exhaust pipe are not blocked;
2.5 confirm that glow plug is not damaged;
3. ignition is normal but ignition failure fault is reported:
3.1 confirm that housingtemperaturesensorisinfull contactwithhousing,thatpressurespringisstrong,and
 that sensoris operating normally;
3.2 confirm that excessive carbon deposition has not occurred, if so this must be cleaned.
