each part of reflow soldering furnace needs to be maintained very carefully.
the following seven dimensions will be used to decompose and maintain each part of reflow soldering furnace.

adjustment method: take the width at the inlet as the reference point.
if the plate outlet is wide or narrow, use fixed pliers and 19mm open-end wrench to separate the chain from the rail rear end rotating gear bar, and then manually rotate the front and rear end driving gear bar to adjust to the same distance with the front and middle end.

it is necessary to manually adjust the track width to the limit in the temperature gear, and then walk back and forth to observe whether the main force affects the track width.

it is also necessary to use a hexagon wrench to check whether the fixed screws of the track are loose.
ensure that the position of the front and rear steel plates at the fixed edge of the track is stable and correct.
