Usage of truck firewood heating switch

1. Turn on the firewood heating switch. At this time, the chassis of the vehicle will make a "bang", which is the sound made by the firewood heater.

2. Add diesel oil to the wood heater, turn on the wood heater controller, and adjust the temperature of the wood heater to a proper position.

3. Wait for a period of time until the diesel oil in the wood heater is completely burned and the vehicle chassis no longer makes a "bang" sound.
