On the sliding block (forming roll) side of the seamer there are two spring rods (part# K9236 / Locking Handle Assembly).
Behind each spring rod there are 3 disc spring washers (part# K9286 / Locking Handle Assembly). These spring rods can be used to increase or decrease seaming pressure.
Insert a pin wrench into the holes on the spring rod and turn clockwise to increase seaming pressure
Turn the spring rod counter-clockwise to reduce seaming pressure.
NOTE: The spring rods are each attached to a separate sliding block. These blocks can be adjusted independently from each other. Adjustments on the front sliding block will affect the first and second stage only. Adjustments to the rear will affect the third and fourth stage.
