CAUTION

◆1.Alwayskeepfuelcan,containers,andburnablematerialawayfromtheburner.Andkeepawet

・ニードルバルブをあけすぎると、生ガスの発生と、燃焼の妨げになります。あけすぎない

ようご注意下さい。

・オイルは、専用のスモークオイルをご使用下さい。

・ニードルバルブはデリケートなので、過度な開閉は避けて下さい。

・２回目からは、発煙タンク内のドレンを抜いてからオイルを入れて下さい。

・Toomuchopeningoftheneedlevalvecausesraw-gasanddiscouragecombustion.So

takecarenottoopenthenozzletoomuch.

・Usethededicatedoilforthesmoke.

・Theneedlevalveisverydelicatesoavoidopeningtoowideorclosingtootight.

・Fromthe2ndoperation,pourtheoilintothetankafterremovingwasteoilfromthetank.
