AKH2.2 - recommended tightening torques*

* maximum value
When bolting together dissimilar materials, always tighten to the lowest
recommended torque of the components in the joint. Using higher torques
may cause excessive deformation of the „softer" material in the joint
The fully closed, waterproof actuator consists of a body with lid, worm gear, input
shaft and hand wheel. For the correct adjustment of the ball position, there are
two adjustable stops mounted in the body.
The gear is fully greased and does not need any further lubrication.
The actuator with hand wheel is mounted on a bracket with four stainless steel
bolts. The on/off position is indicated through a pointer. The actuator is self-locked.
