Power is transmitted via a toggle lever mechanism. This design enables high pressing forces to be achieved despite the compact construction. Important for operation: With the toggle lever mechanism, maximum pressure is only achieved when the toggle lever is fully extended, i.e., just before the end of the stroke. - Hardened spindle - Long spindle guide for high pressure - Adjustable working height - Hand lever ergonomically positioned - The working height can be adjusted quickly and with extreme precision using the threaded spindle
