The KL 1204 is strong, but it hates misalignment. The drive rod must be perfectly aligned with the switch rail connection.

When you crack open the casing (figuratively, of
Fuse check: If the unit fails to power on, check the replaceable fuse located on the front or rear panel. Why Collectors Love It The drive rod must be perfectly aligned with
The hydraulic fluid in the KL 1204 is designed to last a long time, but it isn't immortal. In extremely cold climates, the viscosity of the fluid can change, slowing down the operation time. If you notice the switch moving sluggishly in winter, check the fluid viscosity specifications. Always use the manufacturer-specified fluid; generic hydraulic oil can degrade the seals over time.
