(1) Regularly clean the oil filter, and the interval between each cleaning depends on the quality of the fuel used. If a single oil pipe system is used, an exhaust program is required when restarting the combustion engine after each filter cleaning.

(2) Keep the photosensitive eye clean. The photosensitive eye can be easily removed from the socket, cleaned, and replaced. However, please note that when placing the photosensitive eye back into the socket, the photosensitive part should face forward.

(3) If there is a drain valve installed at the bottom of the fuel tank, the drain valve should be opened every once in a while to discharge any accumulated water and dirt at the bottom of the tank. If possible, the inner wall of the fuel tank should also be cleaned.

(4) Clean the interior of the combustion engine at regular intervals.

(5) The temperature near the combustion engine should not be too high, otherwise it will affect normal operation or cause damage to the combustion engine, especially the control box. Please pay special attention to the insulation of the furnace body. If using a bottom frame instead of a sealed installation, pay more attention to the heat that may leak out from the furnace mouth.

(6) The vicinity of the combustion engine should be kept clean and flammable debris should not be piled up. If fuel leakage is found at the connection of the fuel supply pipe, please check and organize it properly before continuing to use.

(7) Unstable voltage can cause damage to some components of the combustion engine.

(8) The combustion engine should be avoided from being splashed with water.

(9) The design of chimneys should avoid allowing strong outdoor winds to roll back into the furnace chamber,
