1. Place the engraving material between the two rollers and confirm whether they are far
enough apart to support your cylinder without lifting it up too high. Generally the lower
the cylinder sits, the better.
2. When the distance between rollers is not correct remove the 4 fixing bolts at the left and
right ends of the adjustable support shaft, and rotate the fixing bolt of the tensioner one turn
counterclockwise.
3. Move the adjustable roller to adjust the distance between it and the fixed roller according
to the actual situation. When the distance is appropriate, tighten the adjustable roller
fixing bolts.
4. Move the tensioning wheel assembly to make the synchronizing wheel under tension, and
tighten the fixing bolts.
5. Rotate one of the rollers by hand, and check whether the other roller and the synchronous
wheel of the motor rotate together as one. The movement should be smooth, if it is not
you may need to reduce the belt tension slightly.
